Sustainable energy savings 

with heat recovery 

When using rotary screw compressors, boosters and blowers, a considerable portion of the energy generated is lost as heat. However, this doesn’t have 

to be the case: Thanks to innovative heat recovery systems from KAESER KOMPRESSOREN, this heat can be recovered and put to effective use. 

Heat recovery – The right decision 

Energy efficiency: You can significantly reduce your energy costs by recovering recyclable heat. The recovered 

heat can be used to heat spaces, to heat water, or to support industrial processes. You are therefore able to use your 

energy twice and save money at the same time. 

Sustainability: By utilising the recyclable heat from your compressed air supply, you significantly reduce CO2 emissions. 

Heat recovery actively contributes to climate protection and helps your company operate more sustainably. 

Durability: A lower compressor operating temperature means a longer service life. Heat recovery therefore not only 

saves money but also protects your investment. 

Flexibility: Heat recovery systems from KAESER can be adapted to almost any compressor. Whether you already 

have an existing system or wish to install a new one, our innovative technology can be integrated seamlessly. 

Funding opportunities: Government subsidy programmes are available to support energy-efficiency measures.

CEO of JUMO, Fulda, Germany 

Opportunities for the process 

industry, but 2025 remains 

turbulent 

2025 promises new challenges 

as Germany’s economy is faced 

with ongoing turmoil. Even now, 

after just the first few weeks, it’s 

clear that nothing will be easy! 

Yet there are numerous opportunities 

for companies in the process 

industry, in particular SMEs. 

Several key developments that 

harbour tremendous growth potential 

are currently shaping this 

sector. 

The focus on sustainable and 

energy-efficient processes remains 

unbroken. Such technologies 

not only improve the CO 2 

balance, they also address the 

rising demands of customers and 

stakeholders. We have eliminated 

fossil energy carriers entirely in 

our new SENSILO plant near Fulda 

– a clear commitment to sustainable 

production. Companies 

are increasingly focusing on environmentally 

friendly alternatives 

in other areas as well, such as the 

thermal treatment of materials. 

Digitalisation and automation 

Process digitalisation and automation 

continues to be a driving 

force for the industry. Companies 

are increasingly investing in 

digital technologies to improve 

their production processes. As 

a system and solution provider, 

JUMO offers an innovative portfolio 

that covers virtually the entire 

automation pyramid – from the 

field level to the control level to 

the management level, including 

cloud connectivity. We offer tailor-made 

solutions to meet the individual 

needs of our customers. 

These examples impressively illustrate 

the strong position and 

innovative, visionary operations 

of the process industry. However, 

the picture is not quite so rosy in 

view of global business opportunities: 

things are getting considerably 

more difficult here. 

Global challenges 

I believe that business with China 

continues to be risky. Some China 

experts are warning against new 

investments in the Middle Kingdom, 

with the possibility of total 

losses. Conditions in the USA are 

worsening. Under President Donald 

Trump who recently took office, 

the imposition of high tariffs 

on certain goods is already causing 

tremendous uncertainty. My 

prognosis: Doing business with 

own production facilities in the 

USA is potentially profitable. The 

export business with the USA on 

the other hand could become increasingly 

more difficult. 

The process industry is facing a 

suspenseful year with numerous 

opportunities but also great challenges. 

Buckle up: many weeks 

remain in 2025 and they are sure 

to be turbulent.

Process air is omnipresent in the 

maritime sector. It enables energy 

savings, protects the environment 

and marine life, improves safety, ensures 

a smooth ride and much more. 

This may sound like the best sailor's 

yarn, but it's the truth. Professionally 

implemented blower and compressor 

concepts are indispensable 

for a wide range of applications 

and processes and pay off in every 

respect. As a long-standing, experienced 

partner to the maritime industry, 

AERZEN knows understands 

the challenges faced on board and 

provides innovative solutions for a 

wide range of applications. 

Shipping, shipbuilding, marine technology 

and the offshore industry are 

facing major challenges. “Saving fuel, 

reducing CO 2 

emissions, switching 

from heavy fuel oil to LNG drives and 

ongoing cost pressure are currently 

among the biggest issues confronting 

the maritime industry. They are the 

driving force behind innovation and 

are driving the transformation of the 

sector,” explains Torsten Lehmann, 

AERZEN Sales Office Manager for 

Northern and Eastern Germany: “Our 

blower and compressor solutions 

help to fulfil increasing environmental 

and climate protection requirements. 

They reduce energy consumption, 

thus lowering energy costs and 

they improve maritime safety.” 

Heading for the future 

AERZEN blowers and compressors 

combine the expertise and experience 

of more than 160 years of technological 

leadership and prove themselves 

successfully every day in the 

most demanding applications worldwide. 

For maritime applications this 

concentrated sector and application 

expertise is invaluable. “The technology 

on board must first and foremost 

be robust, safe and corrosion-resistant. 

With the short waiting times of a 

ship in the harbour or shipyard, speed 

and worldwide availabili ty of spare 

parts are also essential,” says Torsten 

Lehmann. “We know what our customers 

want and are well networked 

across miscellaneous sectors. This 

experience and expertise is incorporated 

into our solutions for the maritime 

industry,” he adds. The result is 

durable, low-maintenance packages 

with maximum functionality, compactness 

and reliability. AERZEN machines 

are at home on all the world’s 

oceans and they ensure trouble-free, 

economical operation even in stormy 

times. And in the event that something 

should happen, an extensive 

network of service centres, decentralised 

parts warehouses and over 

50 foreign companies ensures worldwide 

service with short reaction times. 

Safe, robust packages 

In terms of variety and flexibility, 

AERZEN’s range of solutions has always 

been market-leading. With its 


Cover story 

very broad and sensibly graduated 

product portfolio and an almost limitless 

range of options and auxiliary 

parts, the innovation pioneer really 

does fulfil every process requirement. 

In the maritime industry, the 

robust positive displacement blowers 

and screw compressors and 

energy efficient screw blowers are 

used. These machines defy the difficult 

conditions at sea and perform 

their work safely and reliably even 

in high waves and extreme temperatures. 

They provide 100 % oil and 

absorption material-free process air, 

fit into any machine room, thanks 

to their small footprint, and are designed 

to run efficiently, smoothly 

and maintenance-free for long periods. 

The packages are certified by 

DNV GL and Lloyd’s Register, among 

others, and can also be used for safety-related 

tasks on board. 

Utilisation of Boil-Off Gas 

Speaking of LNG (liquefied natural gas), 

Boil-Off Gas (BOG) is produced as a byproduct 

during the storage and transport 

of liquefied natural gas. It is liqueinjected 

VMX packages are used. The 

robust machines are designed for reliable 

continuous operation and are 

particularly low-maintenance thanks 

to reduced wear parts. Oil-free operation 

is required when returning the 

Always a hair’s breadth of air at the 

bottom of the keel 

Fig. 3: If process air is blown under the bottom of a ship's hull, this reduces friction between 

the ship’s hull and the surrounding water and thus reduces fuel consumption, Image AERZEN 

Currently, one of the most exciting 

applications is ALS technology (Air 

Lubrication Systems). Here, compressors 

are used to blow hundreds 

of thousands of micro-bubbles of air 

per second evenly under the hull of 

a ship - for example passenger ships, 

container freighters or LNG tankers 

- in order to reduce the friction between 

the hull and the surrounding 

water. According to research reports, 

frictional drag is responsible for 60- 

80 % of a ship’s total drag, and a significant 

reduction in this can lead to 

a sustainable reduction in greenhouse 

gas emissions from ships in 

the order of 6-10 %. AERZEN is at the 

forefront of the ALS market as a technology 

driver, supplier and development 

partner. The proven VML and 

VM compressors are in particular demand 

as well as special positive displacement 

blowers, supplemented 

by VFDs, coolers, piping, regulators 

and isolating valves as well as a master 

control system. Together with its 

partners, the compressor manufacturer 

is developing ever more efficient, 

compact and sound emissionoptimised 

systems in order to meet 

the demanding requirements of the 

Energy Efficiency Design Index (EEDI). 

Fig. 4: AERZEN compressors can feed the Boil-Off Bas, which is produced on LNG tankers during 

transport by heating LNG, back to the ship's engine after pressure adjustment, Image AERZEN 

fied again in a suitable compression 

process and fed back into the tank as 

LNG. However, it can also be used as 

fuel and thus enables climate-friendly 

operation, for example of LNG tankers, 

cruise ships or ferries. AERZEN realises 

application and cost-optimised 

compressor concepts for the handling 

and processing of BOG. If the BOG is 

used as fuel for the ship’s engine,oilreliquefied 

gas to the LNG tank. First 

choice is therefore multi-stage, oil-free 

screw compressors. Bespoke solutions 

optimally fulfil the high safety requirements 

and at the same time offer maximum 

reliability, process safety and 

energy efficiency. And by the way, oilinjected 

compressors from the VMX 

series are also used to supply LNG as 

fuel for the ship's engines.

Water treatment at sea 

Environmental, climate and marine 

protection also play a central 

role in wastewater and 

drinking water treatment. In the 

past, waste water was simply 

to the ship dynamically ensure 

an always smooth and stable 

position in the water. Using an 

exactly dimensioned blower, 

water in the ship’s ballast water 

tanks is pushed from one side of 

the ship to the other via a pipe

oil-free screw compressors that ensure maximum process reliability, Image AERZEN 

dumped out at sea. In the meantime, 

ship wastewater treatment 

plants have become established. 

And where there is a wastewater 

treatment plant, AERZEN technology 

is never far away. The 

company is one of the leading 

international suppliers of ventilation 

systems for aeration 

tanks the expertise of the company 

from Lower Saxony can 

be found in more than 100,000 

waste water treatment plants 

of all sizes worldwide. Shipping 

also bene fits from this unique 

expertise. Mobile plants from 

the supplier are installed on the 

largest passenger and cruise 

ships and enable reliable, efficient 

and sustainable wastewater 

treatment at sea. 

Have a safe journey at all times 

AERZEN solutions also support 

manoeuvring, stabilising and 

keeping ships free of ice. Antiheeling 

systems exactly tailored 

system. The plant uses air valves 

to control which side the water 

is pressed onto, depending on 

the current position of the ship. 

These can change the air flow in 

less than one second. Anti-heeling 

systems with blowers are 

significantly more economical 

and energy-saving than those 

which involve pumps. Cruise 

ships, cargo ships, tankers or 

cable ships lie more calmly in 

moving water and remain stable 

during loading and unloading. If 

the anti-heeling plant is used in 

reverse, a “duck walk” occurs, a 

slight swaying that serves to keep 

ships free of ice. This is used in 

icebreakers, for example. 

CO 2 

injection is still a 

relatively new application. In the 

past, reciprocating compressors 

were used as standard for 

this purpose. However, the process-related 

vibrations can cause 

the perlite, which binds the carbon 

dioxide in the reservoirs, to 

settle. This makes storage and 

removal of the gas more difficult. 

High-pressure blowers (positive 

displacement blowers) are an alternative. 

The machines are dynamically 

balanced and therefore 

do not cause any vibrations. 

Process air protects marine life 

Even on the seabed, nothing 

works without process air. Noise 

emissions are generated during 

the laying of foundations for 

offshore wind turbines. Without 

appropriate measures, these 

spread for kilometres across the 

water and harm fish, marine 

mammals and birds. To protect 

marine ecosystems, so-called air 

curtain systems are therefore 

mandatory for foundation construction. 

Air is blown into the 

sea via a hose, and, using sophisticated 

technology, a protective 

column is created around the 

pile-driving site on the seabed 

by millions of small air bubbles 

rising upwards. These air bubbles 

practically create a protective 

wall so that the sound cannot 

spread from the pile-driving 

site across the sea. This means 

that marine life is not disturbed 

and negatively affected by the 

sound. As a lot of air is required 

fto produce the millions of small 

air bubbles, several oil-free compressors 

are usually needed. 

AERZEN has also installed 

positive displacement blowers on 

survey and research vessels undertaking 

seismic surveys of the 

seabed. The blowers serve as the 

first stage before reciprocating 

compressors (compressor charging). 

Pre-compression means 

that smaller reciprocating compressors 

can be used. The situation 

is similar for borehole blockages 

using highly compressed 

nitrogen. VMX compressors supplement 

the reciprocating compressors 

in the first stage. 

Customer satisfaction 

guaranteed 

Whether process air or process 

gas, whether on the ship or on 

the seabed, whether in inland 

shipping, in the harbour area or 

on the high seas, whether passenger, 

freight, tanker or research 

vessel, there are virtually 

no limits to the possible applications 

of AERZEN positive displacement 

blowers, rotary lobe 

compressors and screw compressors. 

Other fields of application 

include reducing the noise 

level of transverse thrusters and 

propellers on luxury ships (keyword: 

cavitation interruption), 

cooling on fishing vessels, the extraction 

of VOC gases on oil tankers 

and the pneumatic conveying 

of bulk materials during loading 

and unloading. “Thanks to our 

extraordinarily wide portfolio of 

solutions and our flexibility in 

terms of modifications, AERZEN 

leaves nothing to be desired. 

AERZEN is involved in many developments 

of new maritime applications 

and works with its customers 

to develop solutions that 

lead to greater efficiency and 

safety. Whatever the requirements, 

we will find the optimal 

solution. AERZEN makes everything

A perfect homogenisation: 

Customised solution optimises 

gel production in chemical plant 

Stefan Baudner 

Quality and efficiency - to guarantee 

both, precision in the handling of fluids 

is crucial in the chemical industry. 

This was also the case at a longstanding 

German chemical plant, 

which faced particular challenges 

when homogenising gel chunks of 

different sizes. The aim was to generate 

a steady flow with a uniform 

particle size. This challenging task 

required a customised solution considering 

the medium’s sensitivity. 

Using an innovative, customer specific 

solution from NETZSCH Pumps 

& Systems, the manufacturing process 

was optimised regarding quality, 

duration, and costs. Today, the 

chemical plant benefits from a high 

degree of flexibility in production 

and can offer a wide range of highquality 

gels. 

As an expert in producing inorganic 

speciality chemicals, the company 

manufactures high-quality materials 

for users in various industries, including 

hydrogel. It is used to produce 

silica gel, typically used in the protein 

stabilisation of beer, as a matting 

agent in paints and varnishes, or as a 

coating for inkjet paper. 

Tension between homogenisation 

and destruction 

This requires the hydrogel lumps, up 

to 30 mm in size, to be crushed in a 

defined manner so that a steady flow 

of uniform particle size can be realised. 

Like in any process in the chemical 

industry, efficiency and product 

quality take centre stage. 

The material must be handled 

precisely and gently to achieve the 

desired particle size without damaging 

the product. Because the hydrogel

Diaphragm pumps 

Spent caustic requires hermetically tight, 

high pressure pump technology 

Treating spent caustic liquors: Diaphragm pumps used in 

WAO treatment of toxic, hazardous industrial wastewater 

from ethylene plants and refineries 

Wastewater from ethylene production 

in chemical and petrochemical 

industries as well as in petroleum 

refineries poses a particular challenge 

in terms of water treatment. 

As it contains hazardous pollutants 

such as sulfides and mercaptans, 

that do not respond to traditional 

treatment methods, chemical companies 

and refineries resort to Wet 

Air Oxidation (WAO). With elevated 

temperature and high pressure, this 

method is able to achieve oxidation 

of the critical compounds, making 

the liquid suitable for subsequent 

biological treatment. The Best Available 

Technique (B.A.T.), as acknowledged 

by the European Union IPPC 

Commission, is the TOP – Wet Air 

Oxidation process developed by the 

Italy-based process equipment provider 

3V Group. Based on this technology, 

3V Tech manufactures industrial 

scale modular systems that 

reduce the chemical oxygen demand 

(COD) of spent caustic up to 

99 %, with the residual COD being 

detoxified, decolored and almost 

entirely biodegradable. To handle 

the spent caustic water, however, 

the process requires hermetically 

tight, high pressure pump technology 

that is suitable for dangerous fluids 

and allows for adjustable flow 

rates as well as high positioning accuracy. 

For their TOP plants, 3V Tech 

therefore relies on LEWA diaphragm 

pumps, whose patented PTFE diaphragm 

heads provide highest 

chemical resistance. 

“When it comes to industrial wastewater 

from petrochemical and chemi cal 

plants, the effluent is contaminated 

with heavy and complex organic molecules. 

These are particularly difficult 

to deal with,” explains Camilla Navicello, 

Sales Expert from LEWA Italy 

Srl. “Spent caustic liquors are not just 

odorous and highly colored, but, more 

importantly, contain sodium sulfides, 

mercaptans, phenols and emulsified 

hydrocarbons. Wet Air Oxidation 

(WAO) is used to degrade the complex 

organic loaded caustic water at high 

pressures and tempera tures with the 

addition of oxygen in an efficient, environmentally 

friendly and flexible way.” 

Through this process, most hazardous 

pollutants can be degraded into easier 

treatable substances such as carbon 

dioxide, water vapor, sulfite and 

sulfate, and simpler organic forms, 

which are biodegradable in a second 

conventional process stage. 

Among the world market leaders in 

terms of WAO ranks the Italy-based 

3V Group with the TOP – Wet Air Oxidation 

process. In a process similar 

to flameless burning, this method is 

able to oxidize heavy and complex

corrosion-resistant pump technology that is suitable for dangerous fluids and allows for 

high-precision flow rates as well as high positioning accuracy. Image: LEWA

materials. Image: LEWA 

molecules at high temperature and pressure 

levels, reducing the COD of the hazardous liquid 

up to 99 % and permanently removing any 

odor and color. Subsidiary company and process 

equipment provider 3V Tech realizes this 

method on an industrial scale, manufacturing 

turn-key modular systems specifically for the 

toxic, non-biodegradable spent caustic. 

Hermetically tight and safe pumps handling 

hazardous fluids 

To withstand the heavily polluted and odorous 

water, TOP – Wet Air Oxidation plants must be 

equipped with a hermetically tight and safe 

pump. In that respect, 3V Tech approached 

LEWA Italy, as the pump specialists have extensive 

experience in this type of application. 

Drawing on the joint expertise of the teams 

from LEWA Germany and LEWA Italy, the latter 

thus recommended energy efficient LEWA 

ecoflow diaphragm pumps for this challenging 

project: “Our diaphragm pumps are characterized 

by the material as well as design of 

the patented sandwich diaphragm itself,” explains 

Navicello. “Firstly, it is made from PTFE, 

which has higher chemical resistance than 

conventionally used materials like EPDM. Secondly, 

the pump is continuously monitored 

by the reliable DPS diaphragm protection system.” 

The DPS instantly detects if one of the 

diaphragms is damaged, while the sandwich 

diaphragm design is keeping the entire pump 

head hermetically tight even after damage has 

occurred. This particular construction and the 

special diaphragm system are the key to providing 

the state-of-the-art pump characteristics 

required for efficient and safe WAO plants. 

Regarding the material of the other wetted 

components of the LEWA ecoflow pumps, 

standard 316/316L high-grade steel is usually 

fine to prevent corrosion even with highly 

aggressive spent caustic containing sulfide. 

Depending on the specific fluid consistency 

and opera ting temperatures, however, it 

may be necessary to choose special alloys 

such as Ti-Alloy or Hastelloy, which provide 

even higher chemical resistance. Ex-proof 

designs are manufactured, depending on 

the safety zone requests on site. All pump 

components are designed to reliably maintain 

their excellent suction and overall operating 

conditions for extended periods of 

time and require low maintenance. The reliability, 

process safety and operator friendliness 

of theses pumps are outstanding. They 

are essential qualities when dealing with 

such toxic and odorous types of wastewater 

for very different locations worldwide. 

Modular pump design for various ethylene 

and refinery applications 

Through their cooperation with 3V Tech and 

supplying LEWA diaphragm pumps for TOP 

– Wet Air Oxidation for spent caustic plants, 

LEWA Italy has gained extensive experience 

with different WAO applications. Depending 

on the amount of wastewater to be treated, 

LEWA pumps in different designs are used, 

with the very robust and compact LEWA triplex 

pump series being best suited for lager 

installations. Thanks to their variable modular 

design, LEWA can realize specific pump 

solutions for WAO applications to meet all 

kinds of requests. Some locations even require 

challenging documentation and pump 

tests, which are also provided by the pump 

manufacturer. “Although LEWA Italy is in 

charge of the 3V Tech project, we would like 

to thank our colleagues from Germany for 

their close cooperation. With LEWA’s international 

presence, we are capable of realizing 

these types of WAO solutions all over the 

world,” Navicello concludes.

Sugar syrup in motion: 

moving molasses easily 

Verena Schmorleiz 

The conveyance of molasses poses 

major challenges for companies in 

the sugar industry. This is because 

the highly viscous sugar syrup is 

very gooey and therefore requires 

special pump technology. The company 

Hansa Melasse, which specialises 

in the procurement and distribution 

of molasses and related 

products, is also dependent on a reliable 

and efficient solution. In order 

to convey the viscous medium 

smoothly, the company relies on rotary 

lobe pumps from Vogelsang’s 

VX series. They ensure trouble-free, 

maintenance-friendly and economical 

pumping processes. 

Hansa Melasse Handelsgesellschaft 

mbH in Bremen supports its 

customers with comprehensive services 

in the transport, storage and 

handling of liquid products. This also 

includes a storage and delivery service 

for (organic) sugar cane molasses. 

The product range includes sugar 

cane molasses, sugar beet molasses 

and organic molasses. 

Fig. 1: The tank farm of Hansa Melasse Handelsgesellschaft mbH in Bremen.

Complex transport processes for 

variable viscosity 

The Hansa Melasse tank farm in 

Bremen is a central hub for loading 

and unloading ships and storage 

tanks, as well as loading tanker lorries 

and general cargo into IBCs (intermediate 

bulk containers). Tank farms 

in particular place high demands on 

pump technology due to the many 

transport processes. For example, 

the sugar syrup has to be transferred 

from ships into storage tanks and 

from the tanks into lorries or IBCs. 

The viscous consistency of the sugar 

syrup and the conveyance of the medium 

over a long distance with a gradient 

pose particular challenges. 

In addition, the varying viscosity 

of the molasses requires special

tank on the shore. (Source: Hansa Melasse Handelsgesellschaft mbH) 

pump technology: for example, the 

sugar syrup is thinner and easier 

to pump in summer than in winter 

due to the higher temperatures. The 

country of origin and even the producer 

also influence fluidity. This is 

partly due to the different composition 

of the molasses during the 

production process. In addition, the 

viscosity of the medium varies depending 

on the starting product – 

sugar cane or sugar beet. 




Fig. 4: The conveying principle of rotary lobe pumps. 

(Source: Vogelsang GmbH & Co. KG) 

How rotary lobe pumps work 

The pumping principle of rotary lobe pumps is based on two 

counter-rotating conveying elements, the so-called rotary 

lobes. These are mounted on two synchronised shafts. The 

rotary movement of the lobes increases the volume of the conveying 

chamber on the suction side. The vacuum generated 

in this way sucks the medium into the rotary lobe pump. As 

the rotary motion continues, the medium is trapped in cavities 

between the rotary lobes and the pump housing and discharged 

on the pressure side through the conveying chambers 

as they become smaller again. The rotary lobe pump 

delivers the medium directly. Due to their axially symmetric 

design, the pumps are not dependent on the direction of rotation 

and can pump in both directions without restriction. Pulsation-free 

HiFlo lobes ensure low vibration and particularly 

gentle conveyance. 

Smooth processes with rotary 

lobe pumps 

Hansa Melasse relies on several 

Vogelsang rotary lobe pumps 

from the VX186-260QD and 

VX186-130Q series to meet these 

high requirements and convey 

the sugar syrup smoothly. They 

are used at the tank farm in 

Bremen to transport the molasses 

from a jetty on the site to one 

of the three storage tanks on the 

“The viscosity of the molasses depends on 

various factors, such as the country of origin, 

temperature and whether the molasses is 

made from sugar cane or sugar beet.”

Hansa Melasse Handelsgesellschaft mbH 

shore. The company uses additional 

pumps from the VX series, 

some of which are mobile, for onward 

transfer into tanker lorries 

and for filling IBCs. 

The rotary lobe pumps in the 

VX series pump media with varying 

viscosities without any problems 

and with consistent performance 

– even over a long 

distance with a gradient. In addition 

to highly viscous or aggressive 

media of all kinds, they 

also pump liquids containing 

coarse solids without clogging. 

The pumps are self-priming and 

insensitive to dry running and 

foreign bodies – which reduces 

wear, increases system availability 

and ensures that the pumping 

process is trouble-free. The pulsation-free 

HiFlo pistons enable 

a gentle pumping process without 

foaming and ensure smooth 

pump operation. The sugar crystals 

remain intact. A housing geometry 

equipped with the InjectionSystem 

optimises the flow 

of the molasses. Cartridge mechanical 

seals are designed as a 

compact unit. Due to the design 

of the sealing chamber, the seals 

can be checked without removing 

the pump. 

The QuickService 

also 

concept 

enables 

on-site maintenance; 

employees 

can 

carry out service 

work independently without 

dismantling the unit, thereby 

minimising downtime. Thanks to 

their compact design, the pumps 

are space-saving and can be integrated 

into any system. 

Proven technology in 

long-term use 

Hansa Melasse has been working 

with Vogelsang rotary lobe 

pumps for over 20 years in order 

to meet the challenges of 

smoothly conveying the demanding 

sugar syrup and offering its 

customers the best possible service. 

The molasses at the Bremen 

tank farm is pumped reliably 

from station to station.

Almost made 

Gentle conveying of mayonnaise salad 

Mayonnaise salad is traditionally 

found on party buffet tables or, 

fresh from the chiller, makes a 

hearty addition for lunch or dinner. 

Thanks to the gentle conveying by 

WANGEN PUMPS twin screw pumps, 

even delicate peas or diced carrot 

remain appetising and firm to the 

bite in its manufacture. We are currently 

running a test phase to ensure 

that the mayonnaise salad can 

be gently pumped by the series 104 

twin screw pump. 

The challenge: gentle pressure for 

gentle vegetables 

In the test, the mayonnaise salad is 

conveyed to the pump through the 

vertical spigot on the pump housing 

and then through a hopper. The combination 

of gravity and the plug screw 

feeder in the hopper ensures an even 

feed. A DN50 hose with a DN50 outlet 

valve is fitted to the horizontal discharge 

flange. No pressure measurements 

are taken on the pump itself, 

as the theoretical calculated pressure 

losses in the connected hose and outlet 

valve are known in advance. 

Practical test 

Twin screw pumps feature cells between 

the edges of the spindle and 

the pump housing that “shift” from 

the suction to the pressure side due to 

the counter-rotational movement of 

the spindles. As there is no change of 

volume in these cells, the mayonnaise 

salad is transported especially gently. 

After pumping, the testers rinse off 

the mayonnaise with water to evaluate 

the shape of the vegetables. The 

result: at all three pumping rates, the 

required size and form of the vegetables 

is retained. This delicate salad can 

therefore be economi cally pumped by 

WANGEN PUMPS twin screw pumps 

without any loss of quality. 

In short 

WANGEN PUMPS twin screw pumps 

have been proven to be very suitable 

for use in the food industry. The tested 

pump manages to balance costeffective 

production with the highquality 

standards of the product: the 

vegetables are not squashed even at

The series 104 twin screw pumps 

feature a sufficient spindle gradient 

to prevent the product becoming 

squashed between the edges of the

we are testing the pump with 

a salad containing peas, diced gherkins 

and carrots, bound together with 

mayonnaise. The aim is to convey the 

salad without changing its texture 

– so that it looks and tastes almost 

home-made. After all, the appearance 

of the salad would be impaired if the 

vegetables were to be squashed. The 

mayonnaise would take on an unattractive 

colour as colouring could be 

released by the crushed vegetables.

3 questions to Markus Gutfrucht, Application Technology, WANGEN PUMPS 

PuK: How quickly can the spindle 

be changed if the medium to be 

pumped changes? 

Markus Gutfrucht: The spindle 

change takes between 10 minutes 

and 1 hour, depending on the size 

and whether re-synchronisation 

is required. The spindle can be 

changed quickly in a workshop. If 

the pump is installed in the system, 

it is possible that there is no access 

to the pump and it must first be removed. 

Then it takes even longer. 

PuK: How much time can be saved 

on average for cleaning the pump? 

Markus Gutfrucht: Compared to 

a progressive cavity pump, you do 

not save any time, as the CIP line 

has to be cleaned with a CIP pump. 

With a WANGEN Twin NG, which 

delivers the necessary flow rate to 

achieve the corresponding flow velocity 

of 1.5 to 2.1 m/s in the lines 

to be cleaned, you save the CIP 

pump. The CIP pump is an additional 

pump that only needs to be 

provided for cleaning. If the Twin 

NG pump has a sufficiently fast rotating 

motor, then you can save on 

the CIP pump and the corresponding 

pipework for connec ting the 

CIP pump. You also save on the 

CIP bypass on the progressive cavity 

pump and the valve installed 

in the bypass. The savings with a 

twin pump are more in the area of 

hardware. If you compare CIP with 

a twin to mechanical cleaning with 

dismantling the pump and cleaning 

the components in a washbasin 

with brushes, you will certainly save 

up to an hour of time. Depending 

on how the pump is installed. 

PuK: Will the replaced seal cartridges 

be taken back by the manufacturer 

or can they be reconditioned? 

Markus Gutfrucht: The sealing 

cart ridges are not taken back, as 

we would otherwise be under warranty. 

We have no control over 

the substances that are pumped 

with our pumps. What we do offer, 

however, is to supply customers 

with spare parts packages for the 

O-rings, slide rings and springs. 

This allows the customer to replace 

all wear parts on their seals. This is 

a cost-effective alternative to purchasing 

new parts. Customers often 

buy a complete new seal and 

the corresponding spare parts 

packages the first time, with which 

the old seal is then refurbished 

and stored. This means that the 

next time there is a leak, the procurement 

time is virtually non-existent 

and the pump can be provided 

within a very short time (around 

30 minutes for experienced service 

technicians).

Peristaltic pumps in titanium dioxide production 

Flexible and reliable dosing pumps 

for brilliant white 

Titanium dioxide is the world’s most 

important white pigment with countless 

applications. At its Leverkusen 

site, KRONOS Titan researches and 

develops groundbreaking new processes 

and methods for producing 

this crucial substance. For demanding 

dosing tasks at its Technikum, 

the research and technical department, 

where new products and procedures 

are developed, the company 

relies on peristaltic dosing 

pumps from Watson-Marlow Fluid 

Technology Solutions. These pumps 

are valued for their reliability, accuracy, 

easy maintenance, and flexibility, 

which are crucial in the development 

phase. 

Titanium dioxide in everyday life 

Fig. 1: At the acid station, KRONOS primarily relies on Qdos pumps from Watson-Marlow. 

The compact, self-priming pumps significantly simplify chemical storage and dosing applications. 

Titanium dioxide is found in countless 

everyday products. Its application 

spans from paints and coatings 

to plastics, paper, the textile industry, 

pharmaceuticals, cosmetics, and many 

other products. With over 60 % of the 

global production volume, paints, coatings, 

and printing inks are by far the 

largest sectors. Aircraft and ships, usually 

painted white to reflect heat and 

minimise the effects of extreme temperature 

fluctuations, also benefit 

from the durability and high performance 

of titanium dioxide pigments. 

Thanks to its high refractive index 

and excellent light-scattering properties, 

titanium dioxide offers exceptional 

whiteness, brightness, and 

opacity. It not only produces white 

colours but also enhances the coverage 

and durability of vibrant colours. 

A global leader in titanium 

dioxide production 

KRONOS, an American company, is 

one of the world’s leading manufacturers 

of titanium dioxide pigments. 

Fig. 2: For applications requiring higher flow rates of acids or bases, the company also uses 

the 500 and 600 series cased peristaltic pumps, offering flow rates of up to 1,080 l/h depending 

on the pump head used. 

As the oldest and one of the largest 

TiO 2 

producers worldwide, with a 

market share of 11 %, the company 

is recognized as a leader in quality 

and innovation. With more than 

2,200 employees, its own raw material 

mine, and six production sites, it 

stands out in the industry. In Germany, 

KRONOS is the largest titanium dioxide 

manufacturer, with production 

at two sites. 

Research and development 

at the Leverkusen 

chemical production plant 

One of these sites is in Leverkusen 

CHEMPARK, a chemical production 

plant, where titanium dioxide has 

been produced for nearly 100 years. 

This historic site is also a key research 

and development facility, focusing 

on new processes to improve prod- 




uct quality and reduce environmental 

impacts. The world's first rutile-form 

titanium dioxide pigment was developed 

here by one of the company’s 

predecessors. 

The research facilities in Lever kusen 

include several Technika, crucial research 

and technical departments. 

“Here, we can further explore the 

processes and formulations developed 

in the lab on a smaller scale, optimising 

their suitability for scaling up 

to large-scale production,” explains 

Patrick Glebocki, Group Leader at the 

technical center in Leverkusen. 

Peristaltic pumps for demanding 

dosing tasks 

Research in Leverkusen focuses on 

optimising the two main production 

methods for titanium dioxide: 

the sulphate process and the chloride 

process, as well as methods 

that combine the advantages of both 

processes. In all processes, dosing 

pumps play a central role, whether in 

Fig. 3: The only wear part on the entire 

pump is the patented ReNu pumphead, 

which can be replaced as a single component 

in just a few minutes 

dissolving titanium dioxide or breaking 

down titanium ore, during subsequent 

neutralisation, regeneration, 

or reduction processes, or in downstream 

filtration, post-treatment, and 

refining processes. 

Dosing pumps – maintenance in 

minutes 

At the chemical plant’s central acid 

station, KRONOS uses Qdos dosing 

pumps from Watson-Marlow Fluid 

Technology Solutions. These compact 

pumps feature an innovative design: 

the only wear part is the patented 

ReNu pump head, which can be 

replaced in minutes as a single component, 

making the pump “as good 

as new.” The sealed pump head prevents 

fluid leaks, ensuring the operator 

never comes into contact with the 

pumped fluid. 

The versatile Qdos dosing pumps 

are used in countless chemical applications. 

A variety of pump models are 

available to meet different requirements, 

with flow rates ranging from 

20 l/h to 600 l/h and extensive control 

options, including manual control, 

4-20 mA, Profibus, ProfiNet, or 

Ether net. Different tubing materials 

are also available for da broad variety 

of applications, ensuring optimal 

chemical compatibility. 

We tackle the 

challenges of the 

future – with our 

intelligent vacuum 

solutions.

KRONOS uses Qdos 120 models, delivering 

up to 120 litres per hour at 

a pressure of up to 4 bar. For applications 

requiring higher flow rates 

of acids or bases, the company also 

utilises the 500 and 600 series cased 

peristaltic pumps, offering flow rates 

of up to 1,080 l/h depending on the 

pump head used. For the 500 and 

600 series cased pumps, a wide selection 

of different hose materials 

and pump heads is available in addition 

to various drive options. This includes 

the innovative LoadSure hose 

connectors from Watson-Marlow, 

which enable particularly easy hose 

replacement. 

Superior dosing accuracy 

All Watson-Marlow peristaltic pumps 

provide a key advantage: superior 

dosing accuracy. “We need precise 

control of our experiments in 

the research and technical department, 

and we must rely on the accuracy 

of the dosing pumps used,” says 

Patrick Glebocki. The pumps ensure 

reli able accuracy of up to 0.5 % even 

with highly concentrated chemicals, 

offering exceptional flexibility across 

the entire flow range. 

Challenges with diaphragm pumps 

Fig. 5: At the dosing station for bases, KRONOS primarily relies on 600 series cased peristaltic 

pumps and Qdos metering pumps. 600 series pumps offer a flow rate of up to 1,080 l/h 

with very high accuracy. 

Fig. 6: The Qdos metering pump is available in different sizes with maximum flow rates 

ranging from 333 ml/min to 600 l/h 

“We previously used diaphragm 

pumps for dosing acids and bases,” 

explains Rafael Gasior, team leader 

at KRONOS. “However, we often encountered 

dosing errors and had to 

repeatedly adjust the stroke length, 

recalibrate, and reprime.” Peristaltic 

pumps eliminate these issues, as 

they are self-priming and do not require 

manual priming. 

This is especially beneficial in 

the technical centre: “Diaphragm 

pumps had frequently faced priming 

issues, requiring us to store chemical 

containers on elevated platforms 

to avoid suction problems. Peristaltic 

pumps are self-priming, facilitating 

container replacement or recipe 

changes. This eliminates the need 

for additional feed pumps and allows 

us to store chemicals on the 

same level as the pumps, significantly 

simplifying our workflows,” says 

Rafael Gasior. 




Easy installation and comprehensive 

control options 

Replacing diaphragm pumps with 

peristaltic pumps was straightforward. 

Unlike other dosing pumps, 

peristaltic pumps require no diaphragms, 

valves, or seals and usually 

do not need pulsation dampeners, 

ensuring minimal maintenance and 

easy integration into existing dosing 

systems. 

Operating the pumps is also userfriendly: 

“Unlike diaphragm pumps, 

no extensive training is needed for 

our staff,” notes Patrick Glebocki. Additionally, 

the pumps offer various 

communication and connectivity options, 

such as 4-20 mA, PROFIBUS, 

ProfiNet, and Ethernet/IP for modern 

process control. Another advantage 

is their reduced noise level compared 

to diaphragm pumps. 

Efficient and flexible for multiple 

applications 

Due to the closed pumping principle—only 

the inner surface of the 

tube contacts the medium—pro duct 

changes and cleaning are much simpler 

than with diaphragm pumps. 

This efficiency, combined with reliability, 

accuracy, easy maintenance, 

and flexibility, makes Watson- 

Marlow peristaltic dosing pumps the 

preferred choice for KRONOS. 

“The Watson-Marlow peristaltic 

dosing pumps provide the reliability, 

accuracy, easy maintenance, 

and flexibility we need for our research 

and technical department. 

That’s why they will remain our first 

choice for dosing tasks in the future,” 

concludes Patrick Glebocki Group 

Leader at KRONOS.

Vacuum Technology 


From wind tunnels to space: vacuum 

for aerospace research 

At the German Aerospace Center 

(DLR) in Göttingen, scientists are 

exploring the phenomena of compressible 

flow mechanics in Europe’s 

largest and most powerful tube 

wind tunnel using a COBRA screw 

vacuum pump from Busch Vacuum 

Solutions. The goal is to make the 

aerospace of tomorrow safer and 

more efficient. 

more efficient? And how can you use 

precise computer simulation of supersonic 

flight to evaluate new configurations 

while still in the design 

process? The scientists want to provide 

answers to these questions, and 

many others, with the tube wind tunnel. 

Vacuum technology from Busch 

is an indispensable part of these research 

projects. 

tunnels, which enabled studies with 

supersonic and hypersonic flows to 

be carried out. He called this principle 

a tube wind tunnel – which to this day 

is also known around the world as a 

“Ludwieg tube.” In 1968, the Ludwieg 

Tube Wind Tunnel, Göttingen (RWG) 

was the first of these large-scale aerodynamic 

research plants in the world 

to be put into operation. It is still in 

use at the DLR to this day. 

Experiments at supersonic speed

80 meters in length run over an open

The enormous dimensions of 

the research facility become clear as

Institute of Aerodynamics and Flow 

Technology at the DLR in Göttingen. 

Inside, a giant vacuum vessel with a 

volume of 50 m³ is connected to the 

tubes. Detailed and fundamental 

studies are carried out there to investigate 

the fluid mechanics phenomena 

that are essential for adequately 

predicting the performance of supersonic

environmentally friendly, safer and 

The large-scale research facility was 

opened in the 1950s. Göttingenbased 

physicist and flow researcher 

Prof. Hubert Ludwieg developed a 

revolutionary drive system for intermittently 

operating high-speed wind 

The operating principle of the tube 

wind tunnel uses the interaction of 

pressure and vacuum, where the 

accumulator tubes serve as pressure 

vessels in which the air is compressed. 

To prevent air condensation 

in the ultrasonic nozzle, which occurs 

due to the strong expansion and the 

associated cooling of the air, the accumulator 

tubes must be heated to 

simulate high supersonic velocities. 

The accumulator tubes are connected 

to the ultrasonic nozzle via a 

quick-action slide valve. The measuring 

section is found at the end. This 

is where experiments are carried out. 

At the end of the measuring section 

is the vacuum vessel, which the vacuum 

pump is connected to. A vacuum 

slide valve between the measuring 

section and the vacuum vessel 

enables access to the measuring section 

as required. The vacuum vessel 

is evacuated using the vacuum

pump. A COBRA NX screw vacuum 

pump from Busch Vacuum Solutions 

is used for this. It generates vacuum 

of approximately 10 to 40 mbar in 

the vacuum vessel. In the accumulator 

tubes, there is overpressure of approximately 

2 to 40 bar. 

To perform a test, the test model 

is placed in the measuring section 

using a movable model holder. Test 

models include aircraft models, sensors 

or material samples. Opening 

the quick-slide valve creates a running 

dilution wave that flows into the 

accumulator tube and accelerates the 

accumulator air towards the nozzle. 

Due to the differential pressure between 

the accumulator tube and the 

vacuum vessel, and thanks to the 

specially shaped ultrasonic nozzle, 

an ultrasonic flow is created in the 

RWG measuring section. Speeds of 

up to Mach 7 can be achieved – corresponding 

to seven times the speed 

of sound. Measurement times of up 

to 350–400 milliseconds are realized 

in the RWG. This is a peak value for 

wind tunnels of this type and gives 

researchers enough time to study the 

flow around the test models. During 

this time period, statistically relevant 

data or image sequences can be recorded 

to enable reliable data averaging 

and analysis.

cial that the vacuum pump used works 

reliably, because the flow generated in 

the tube wind tunnel must be clean. 

The tests are often carried out several 

times, and it is important that the conditions 

are reproducible at all times – 

which is why nothing should interfere 

with the flow.” The performance of the 

COBRA also made a very positive impression. 

Compared to the previous 

rotary vane pump, the screw vacuum 

pump evacuates the vacuum vessel 

twice as fast. The most commonly 

required pressure of 50 mbar in the 

vessel is now reached after just 15 

minutes instead of half an hour. These 

shorter run times have a very positive 

effect on the ener gy consumption of 

the plant. In addition, a frequency converter 

adapts the vacuum pump's rotational 

speed to the required pressure 

conditions. 

The institute’s employees are also 

pleased with the new vacuum solution. 

Previously, they were unable 

to use the working rooms directly 

above the plant during the tests due 

to the high noise level and vibrations 

genera ted by the old vacuum pump. 

This is no longer a problem, as it operates 

very quietly and with low vibration. 

“You can’t hear anything except 

a slight buzz,” laughs Pfeiffer. Another 

major benefit is oil-free operation. “In 

the past, I had to do hands-on work 

regularly and change the oil – and 

then also change my resulting dirty 

clothes. This is no longer necessary. 

Maintenance is carried out by a Busch 

service technician as part of a main- 

tenance contract. All I have to do is 

switch on the pump and it starts running,” 

says Pfeiffer happily. Above all, 

the proximity of Busch to customers 

is a key benefit. Thanks to the company’s 

extensive service network, the local 

contact person can be on site very 

quickly when needed. 

Clean vacuum for technological 

progress 

The reliable vacuum solution plays a 

key role in the success of the experiments 

in the RWG and supports technological 

progress. The DLR makes 

the results of its basic research available 

to companies in the aerospace 

industry to develop and refine technologies 

for current and future missions. 

The Göttingen-based scientists 

also work closely with international 

organizations such as NASA, ESA 

and the other DLR sites on global research 

projects. In the past, for example, 

a model of the X-38 spacecraft 

was tested in the Göttingen Ludwieg 

Tube Wind Tunnel on behalf of NASA 

and ESA. This craft was intended as a 

crew return vehicle (CRV) to be able 

to bring ISS astronauts back to Earth 

in the event of an emergency. This 

type of spacecraft must withstand 

enormous heat and mechanical loads 

when entering the Earth’s atmosphere. 

These conditions were replicated 

as accurately as possible in the 

tube wind tunnel. 

“Despite enormous advances 

in numerical flow mechanics, many 

phenomena in turbulent flows still 

cannot be adequately and accurately 

predicted. In our studies, we create 

an important validation database that 

helps improve existing models and 

develop new numerical calculation 

methods. We see this as the actual 

purpose of this research facility,” says 

Schülein. Vacuum technology from 

Busch is an important part of this.

PERIPRO ® tube pump: Reliable dosing 

pump for a wide range of applications 

NETZSCH Pumps & Systems, the global specialist for conveying complex 

media, is expanding its product portfolio in the field of peristaltic 

pumps with the PERIPRO ® tube pump. The pump has been specially 

developed for demanding dosing applications and enables efficient 

pumping in numerous areas of application. 

Photo © : NETZSCH Pumpen & Systeme GmbH 

As a global expert in the development, manufacture and sale of pumps 

and systems, NETZSCH has been offering customised and sophisticated 

pump solutions for over 70 years. Customer satisfaction is always 

the top priority for NETZSCH. This is why the products are constantly 

being further developed and adapted to meet the needs of customers. 

The PERIPRO ® tube pump is a robust pump, equipped with big rollers 

to reduce friction between the rollers and the tube, resulting in a 

lower power consumption. Its hermetically sealed design provides the 

perfect solution for applications where no liquid may escape from the 

pump housing, such as in wastewater treatment or the chemical industry. 

This way, leakages into the atmosphere are prevented, therefore 

protecting employees and the environment. The pump is also 

equipped with a leakage sensor as standard, helping to detect tube 

ruptures at an early stage and enabling the customer to intervene 

quickly in order to prevent any further damage within the pump. 

The pump offers a 24/7 continuous operation, ensuring performance 

to the process. It features a robust drive, providing the necessary 

power and durability for demanding applications. By reversing 

the rotation direction, the pipes can be emptied after use. In combination 

with the big rollers, the pump ensures consistent and high-performance 

operation, making the system ideal for a wide range of industrial 

uses. It can handle a wide range of complex fluids including products 

containing solids, viscous, corrosive or in multiphase state. 

The configuration is without any rotating parts coming into contact 

with the fluid. Besides that, it is not necessary to have a sealing system. 

This design significantly reduces maintenance costs, as there are fewer 

components that can wear out or require frequent service. Additionally, 

the absence of a sealing system simplifies the overall maintenance 

process. This combination of features ensures that the pump operates 

efficiently, providing a cost-effective solution. 

In addition, the pump has the capability to evacuate air from the 

suction line, eliminating the need for foot valves, flooding systems or 

other auxiliary equipment. Combined with its precise dosing capability 

up to 26 litres per hour at pressures up to 4 bar, the tube pump is ideal 

for applications, where maintaining strong and reliable suction is critical, 

while also ensuring highly accurate dosing. 

Since the media does not have to lubricate any rotating parts, the 

pump can run dry indefinitely. Furthermore, it does not require the installation 

of a suction or discharge valve. This makes the tube pump perfect 

for products that typically cause problems with valves. The absence 

of valves simplifies the system design and reduces the risk of blocking 

or malfunction, ensuring smooth and uninterrupted operation. 

The new PERIPRO ® tube pump offers numerous advantages, making 

it an ideal addition to the NETZSCH product portfolio. Its precise 

dosing capabilities for small volumes, combined with its versatility 

across a wide range of applications, creates the perfect solution for different 

process needs. This pump ensures accuracy, reliability, and efficiency, 

making it an excellent choice for optimizing operations.

Industrial wastewater pumps at PCK 

Refinery in Germany achieve 25 years 

of reliable operation 

A quarter-century has passed since PCK Refinery GmbH in Schwedt/ 

Oder renovated its canal systems, the so-called main sluice. In 1997, 

two solution approaches were pursued and compared with each other. 

Photo © : NETZSCH Pumpen & Systeme GmbH 

The conventional approach consisted of renewing the underground 

pipe systems. The second solution concept envisaged placing a pump 

station at each plant. In this approach, the slop products of the production 

plant as well as the resulting rain and surface water are pumped via 

an existing pipeline network on the pipe bridges to the central wastewater 

treatment. The second solution approach was awarded the contract. 


PCK Refinery GmbH initiated discussions with various pump manufacturers. 

The composition of industrial wastewater can vary greatly, 

and corrosive substances can also enter the pits. Therefore, the 

minimum requirement for the material of the parts in contact with 

the medium was defined as Duplex 1.4462. The design temperature 

of 80 °C ruled out the use of submersible motor pumps. Ultimately, 

PCK specified submersible pumps with a dry-mounted IEC standard 

motor. The switch-on level for the pumps had to be chosen to avoid 

backflow into the inlet channels. This resulted in installation lengths 

of 2.5 to 5 m.

The Swiss pump manufacturer EGGER was one of these potential 

suppliers. As a pump manufacturer specializing in solid-laden fluids, 

EGGER was able to convince during the technical award. The 

patented Turo ® Vortex hydraulics has an impeller completely retracted 

into the housing with a free ball passage the size of the pressure 

nozzle. Clogging can be virtually ruled out, and coarse solids 

such as stones, branches, screws, or other coarse materials can pass 

through the pump without any failure. Moreover, the pump is selfsufficient 

and operates without any external supply such as sealing 

fluid. The shaft seal as a single-acting mechanical seal sits directly 

behind the impeller. The slide bearings above are lubricated with a 

clean liquid supply and do not come into contact with the pumped

Intelligent pump monitoring optimizes 

the use of ABEL pumps 

For decades, ABEL has been offering reliable and efficient pump solutions 

for a wide range of industrial sectors, such as wastewater, mining, 

ceramics, recycling, etc. ABEL pumps are used worldwide for the 

transport of sludge and abrasive media. Due to their robust construction 

and high performance, the pumps of the northern German engineering 

company are ideally suited for use in various industries. An 

outstanding is their durability. Many national and international companies

medium. Through a water-glycol mixture, the pumps are additionally 

frost-proof, and the journal bearings are protected against corrosion. 

In addition to these technical advantages, the very positive 

operational experience with already used pit pumps was the reason 

for placing the order for a total of 48 pumps of this type with EGGER 

in 1998. Two pumps were installed per wastewater station. The base 

load pump is operated via variable speed drive controlled by the liquid 

level. The second pump with fixed speed serves as a reserve and as an 

overload pump, which is switched on in parallel during heavy rainfall. 

After over 25 years of operation, it can be positively noted that the 

EGGER shaft pumps of the SG type have proven themselves excellently. 

Subsequently, other application sites were also equipped with EGG- 

ER submersible pumps, including pits and tanks classified as Zone 0. 

Further very demanding applications followed, so that currently over 

100 EGGER products are in use in the refinery. 

To further extend the product cycle and efficiency of the pumps, ABEL 

has developed the Smart Pump Assistant. It is an innovative, AI-supported 

monitoring system that enables predictive maintenance of 

pumps. Therefore, relevant process data is sent to the cloud where it 

is analyzed by an in-house developed tool, and users are continuously 

informed about the status and action recommendations for their 

pumps, ensuring efficient and reliable operation. The system provides 

information on the general condition of the pump, but also details 

on the safe running time of wear parts or detected fault patterns and

Customised high-pressure cleaning 

system for EMR Elektromaschinenbau 

In Bavaria 

The sera Group stands for innovative and application-orientated solutions. 

A current example is the development and delivery of a customised 

high-pressure cleaning system to Elektromaschinenbau Ruhstorf 

(EMR) in Bavaria. 

Fig. 3: Predictive pump maintenance 

From the outset, the focus of the collaboration was on developing a 

solution that is precisely tailored to EMR’s specific requirements. Continuous 

dialogue between the companies played a central role in this. 

EMR had clear requirements – including the highest standards of quality 

and efficiency. These were not only met, but exceeded through technical 

innovation and precise customisation. 

The result of the collaboration is a continuous flow system that has 

been specially designed for cleaning special profiles for powder coating. 

The system combines the latest dosing and conveying technology 

and ensures optimal cleaning results thanks to the precise interplay of 

pressure, water volume and specially adapted nozzles.

their location via app or email. The data supports the maintenance of 

the pump itself but can also provide conclusions about adjacent plant 

components. The system is active around the clock and identifies 

anomalies at an early stage. 

Users of the ABEL Smart Pump Assistant will appreciate its benefits. 

Early detection of wear and other problems allows maintenance 

work to be planned and unplanned downtimes avoided, resulting in reduced 

downtime. The key is predictive maintenance. Data-based maintenance 

planning ensures process reliability with maximum utilization 

of wear parts and greatly reduced maintenance effort, which increases 

cost efficiency. The Smart Pump Assistant ensures that pumps are 

always operating in optimal operating condition, optimizing efficiency 

and reliability. Continuous monitoring and analysis of pump data 

enables informed pump and process conclusions and recommendations 

to be made, enabling data-based decisions. Overall, ABEL pumps, 

optimized by Smart Pump Assistant, help reduce operating costs and 

improve workflow efficiency. In addition, plant operators also benefit 

from a “peace of mind” that relies on the Smart Pump Assistant, and 

resources can be used where they are really needed. 

Technical details of the system 

The high-pressure cleaning system is equipped with two flexibly deployable 

nozzle rings that can handle different types of profiles and 

paintwork – both in single and parallel operation. At the heart of the 

system is a high-performance unit with four high-pressure pumps 

that work at a pressure of 250 bar and a delivery rate of 31 litres per 

minute. With dimensions of 2,600 mm x 1,400 mm x 800 mm, the system 

is designed for high performance and efficiency. 

One particular advantage of the system is the drastic reduction in 

cleaning times. Where EMR previously needed around eight hours a 

day for cleaning, it now takes just two hours. The cycle time per profile 

is only about a minute. At the same time, an integrated water treatment 

system ensures resource-efficient operation – a decisive contribution 

to greater sustainability in industrial cleaning.

BRINKMANN PUMPS launches innovative solution for efficient pump 

maintenance 

With the introduction of the new “bproductive” app, BRINKMANN 

PUMPS is taking customer service and technical support to a new level. 

BRINKMANN PUMPS has always been known for its fast and reliable 

support - with bproductive, this claim is now being extended digitally. 

The app developed in-house offers customers an early opportunity to 

identify technical problems or potential faults with the pumps in use. 

This is made possible by access to pump data, which can also be made 

available as a report. If a pump is not working as usual or a fault occurs,

maintenance and fast customer support, Photo: Brinkmann Pumpen 

support can be requested quickly and easily via the app. Users can 

send relevant information directly, including detailed reports, images 

or videos, to enable the service team to accurately assess the problem. 

This reduces delays caused by queries and ensures that solutions are 

provided more quickly. Thanks to optimized communication between 

customers and support, downtimes can be minimized. 

In addition, bproductive creates a transparent overview of all registered 

pumps. Customers can manage their pumps, create groups for 

specific systems and access all relevant information centrally. With the 

deep integration of the “bpsense” condition monitoring system, the app 

enables direct interaction with the pumps so that potential faults can be 

detected at an early stage and preventative measures can be initiated. 

Technically, bproductive impresses with its simple registration 

of pumps by serial number and pump type. If the pump is equipped 

with a bpsense, data can be recorded quickly via an NFC interface. The 

bpsense pump monitor records essential operating data such as energy 

consumption, operating hours, direction of rotation, vibration 

speeds, temperature, current and voltage. The app can also be used 

to create detailed pump reports, which can be saved in the history and 

exported as a PDF for documentation purposes. 

The user-friendly app will be available for both iOS and Android and 

will support companies in their digital transformation from June 2025.

less expensive single-head pump to be used in this transitional area. 

However, their high residual pulsation can be the deciding factor for 

switching to a three-headed pump, which only has approx. 20 percent 

residual pulsation due to the superimposition of the flow rates. LEWA 

has therefore added a new size to its portfolio of triplex process diaphragm 

pumps in 2024. The LEWA triplex G3E is the smallest of its kind 

to date. With a hydraulic output of 10 kW, it offers a low-pulsation alternative 

to single-head pumps in the medium output range. Compared 

to a three-headed pump with a modular design, the G3E also requires 

a footprint that is around 30 percent smaller. 

“Triplex pumps are the first choice for applications that rely on a 

particularly low-pulsation flow rate,” says Thomas Bökenbrink, Lead 

Product Manager Pumps at LEWA. “Due to their design, these pumps 

have a residual pulsation of only approx. 20 percent, since the flow rates 

of the individual plungers overlap.” In principle, 3-headed pumps can 

be built in a modular or monoblock design. The combination of sever-

Compact triplex diaphragm pump in 

robust mono-block design for smooth 

metering and unique power output 

Around 30 percent space savings compared to modular pump models 

For applications in process technology with medium hydraulic outputs, 

the question often arises as to whether the pulsation of an oscillating 

pump with only one plunger is too high. It is not uncommon for a

al individual units in a modular design requires more space as well as 

additional couplings and gaskets, which comes at the expense of simplicity 

and robustness. So far, the lower costs of the modular solution 

have compensated for the disadvantages of this design. For this reason, 

LEWA generally met requests for particularly low-pulsation pumps with 

a three-pump combination of modular LEWA ecoflow drive units. With 

the new LEWA triplex G3E, however, the pump manufacturer from Leonberg, 

Germany, is now ushering in a new era for process technology 

applications with medium hydraulic outputs. 

Monoblock design is efficient and “bullet proof” 

As with all models in the LEWA triplex series, the three plungers of what 

is now the smallest triple process diaphragm pump are located in a common 

crankcase. The monoblock design not only makes the unit more 

compact than comparable modular solutions; it also has fewer individual 

components like gaskets and couplings, which makes the machine 

extremely robust. Thanks to this design, the LEWA triplex G3E can also 

be operated with stroke frequencies that are not possible with modular 

pumps. “Many of our customers appreciate that LEWA triplex pumps are 

virtually 'bullet proof' and can easily withstand even the most demanding 

application conditions,” Bökenbrink notes. “However, the design also 

makes maintenance extremely easy for specialist personnel: for example, 

the gearbox is very easy to inspect even when it is installed.” 

Due to its robustness, the LEWA triplex G3E can run significantly 

faster than modular three-headed pumps. It has a permissible stroke 

frequency of up to 350 spm, which is very high for this size range. It 

thus achieves a maximum flow rate of around 20 m 3 /h at 16 bar. However, 

pressures of up to 400 bar are also possible at lower flow rates. 

With these technical specifications, the new development closes a crucial 

gap, also in terms of overall project costs, as Bökenbrink comments: 

“With the new triplex process diaphragm pump, a jump to the 

next larger machine can often be avoided. Above all, this reduces the 

investment costs for users.” 

High efficiency and long life espan 

In several respects, the LEWA triplex G3E is more efficient than modular 

variants. As already mentioned, the monoblock design is more compact 

from the outset, since there is no need for additional connecting 

elements. And there is the vertical design of the motors, which reduces 

the footprint by a total of 30 percent. In addition, the new triplex process 

diaphragm pump achieves extraordinarily high efficiencies of between 

80 and 90 percent over a very broad operating range. “In a fuel 

gas supply system on a ship, in this example a very large gas carrier 

(VLGC) with a cargo volume of approx. 90,000 m³, the energy costs 

would be reduced by around 20,000 to 30,000 euros per year compared 

to another pump technology with significantly lower efficiency,” 

says Bökenbrink in conclusion. “In combination with the low wear of 

the few wear parts, this economic advantage is multiplied by the life 

expectancy of 20 to 40 years.”

Emission-free URACA plunger pumps 

An important step in environmental protection: The development of 

an emission-free pump design allows the plunger pump manufacturer 

URACA to handle critical media under high pressure without them being 

released into the environment. 

Pumping aggressive problem fluids with high displacement and under 

high pressure is the speciality of URACA plunger pumps. 

High pressure plunger pumps from URACA are designed and manufactured 

for a vast variety of applications with respect to power and 

pumped medium. The machines normally work in continuous operation. 

The flow volumes may reach up to 11,000 l/min/2,900 USGPM, the 

operating pressure is up to 3,000 bar/43,500 psi. Dampers on suction 

and pressure side enable low pulsation and thus reliable and secure 

operation of the overall system. A particular advantage are the high 

rates of efficiency and the related economical operation of the pumps. 

Pumping neutral and aggressive thin liquid and viscous as well as 

abrasive media is no problem for URACA pumps, whereby the temperature 

ranges may vary from extremely cold up to very high temperatures. 

Taking care of the constantly increasing requirements regarding 

environmental protection, the high-pressure pump manufacturer 

URACA developed a concept that allows the pumping of critical media 

with plunger pumps under high pressure without the pumped media 

escaping to the environment. 

The aim was to transfer the legal requirements from the BImSchG 

to a high-pressure plunger pump and prevent its emissions of air pollutants. 

As a result, the safety and health of the operators can be guaranteed. 

The “TA Luft” (Technical Instructions on Air Quality Control) and 

its limit values for emissions are used as a basis. Compliance with TA 

Luft ensures that the valid EU regulations are implemented. In this context, 

emissions are defined by TA Luft as “the air pollutants emitted by 

a plant”. 

The emission-free pump design was realized by using a sophisticated 

and tailormade sealing concept with special oil sealing at the stuffing 

box. This prevents the pumped liquid escaping from the plunger pump 

in the rear stuffing box area. 

In general, all pump models from small to big can be equipped with 

this very special sealing method in order to achieve „technically tight 

status in the sense of TA Luft and VDI 2440“. The corresponding TÜV 

statement can be found in the download area at URACA website.

Watson-Marlow launches new 

Bredel Heavy Duty hose pump for 

toughest applications in mining and 

construction 

Bredel Hose Pumps, part of Watson-Marlow Fluid Technology Solutions 

(WMFTS), has launched the new Bredel Heavy Duty pump for the 

toughest applications in the mining and construction sectors. Building 

on the existing Bredel series, the world’s leading hose pumps for industrial 

applications on the market, the new Heavy Duty pump offers 

increased safety features and improved durability for maximum lifetime 

and minimum maintenance. 

Emission-Free URACA Plunger Pumps, Image: URACA 

The Heavy Duty pump is an ideal solution for handling difficult solids in 

the mining and construction industries, such as transferring abrasive 

high-solid content slurries, thick sludge and corrosive fluids with flow 

rates to 108,000 l/h and pressures up to 16 bar. A robust frame enables 

safer pump transportation using a forklift truck, while heavy duty 

bearings provide an extended lifetime when pumping high-solid content 

slurries. The new Bredel Heavy Duty pump’s safety features also 

include a window guard that offers extra protection, a flange bracket 

that reduces the risk of lubricant leakage and lowers maintenance, as 

well as a C4H paint coating that brings higher resistance for harsh environments. 

Like all Bredel hose pumps, the new Heavy Duty pump has no 

valves or seals to leak, clog or wear making it the ideal solution for han- 




Operating principle 

The new chemical bellows pumps are based on the principle of a positive 

displacement or rotary lobe pump. Due to their simple design and 

numerous possibilities, these pumps are the optimal solution for your 

aggressive and demanding pumping tasks. 

The fluid is pushed by the eccentrically rotating piston (rotor) inside 

the pump housing, from the suction port towards the discharge 

port. The flow direction of the pump corresponds to the rotation direction 

of the motor. In both flow directions the pumps deliver their full 

pumping capacity. 

An elastic rubber component (the so-called pump bellows) completely 

covers the rotor and is available in various materials: FKM, 

EPDM, Buna (NBR) for oils. The pump bellows is simultaneously 

pressed tightly against the housing by the flange and end plate. As a 

result, the rotor and internal components of the pump are completely 

separated from the conveyed medium. Therefore, the fluid being 

pumped only gets in contact with the inner surface of the housing and 

the outer surface of the elastic pump bellows, with the latter being the 

only component subject to natural wear. 

The pump flange and end plate are made from durable cast steel 

and are specially coated. Due to the closed design, the shaft and bearings 

are well protected against aggressive external influences. 

Self-priming, dry running capability and minimal wear 

Due to their design, the chemical bellows pumps are self-priming and 

completely dry-run safe. They are suitable for mobile and stationary 

use and guarantee the highest level of safety and flexibility when 

pumping aggressive chemicals such as acids and alkalis. The pumps 

contain no moving seals, stuffing boxes or valves. They are insensitive 

to soft particles.

Electric chemical bellow pumps 

made of Polypropylene and PVDF for 

pumping aggressive media such as 

acids and alkalis 

The Ottobrunn-based pump manufacturer JESSBERGER has further 

rounded off its production program and will present its new chemical 

bellows pumps to a broad audience for the first time at the European 

Coatings Show in Nuremberg. 

Drives and options 

In addition to three-phase motors, single-phase motors are available 

as an option. Unlike air-operated diaphragm pumps, these pumps 

are particularly energy-efficient and convince by offering low energy 

and operating costs. The drive speed for all pumps is 1500 rpm, with 

a power requirement of 0.25 kW for sizes JP-900.5 to 18, 0.37 kW for 

size JP-900.35, and 0.55 kW for size JP-900.70. Due to the electric motor, 

the pumps operate independently of rotation direction, allowing 

the direction of flow to be reversed. The flow rate can be adjusted via 

a frequency inverter. 


39



Five pump sizes 

From May 2025, five pump sizes will initially be available from the 

Ottobrunn pump manufacturer: 

JP-900.05, nominal capacity 05 l/min. 





According to managing director, Tobias Jessberger, JESSBERGER strategically 

rounds out its production program with this new product line: 

“Our more than 13.000 customers and we have always lacked electric 

pumps that have a suction hose instead of a rigid suction tube and that 

are also self-priming and capable of running dry. With the new chemical 

bellows pumps, we have been able to impressively close this gap. 

These are simple and universally applicable pumps that are suitable 

for a wide range of applications. The ability to change the flow direction 

also makes these pumps very attractive to many customers.” 

An overview of the advantages 

– Electric drives in 230/400 V or 230 V 

– Frequency inverter as an option for regulating the flow rate 

– Possibility of changing the flow direction 

– Pump housing made of Polypropylene and PVDF, Polyethylene as 

an option 

– No metal pump components coming into contact with the medium 

– Use of suction and discharge hoses instead of a rigid suction pipe

AchemAsia 2025 

AchemAsia 2025: 

Where innovation meets industry 

AchemAsia is back: from 14 to 16 

October 2025, the trade show in 

Shanghai will once again present itself 

as the leading platform for the 

Chinese process industry as well as 

the chemical and pharmaceutical 

sectors. As the ‘International Expo 

and Innovation Forum for Sustainable 

Chemical Production’, the focus 

will be on innovative technologies 

for a climate-neutral future, including 

process technology, pharmaceutical 

technology and digitalisation 

(primarily using AI and robotics) 

as well as the rapid development of 

a hydrogen economy and hydrogen-based 

processes in the Chinese 

chemical industry.

China is the largest global player in 

both the chemical and pharmaceutical 

industries contributing almost 

half of the world’s chemical output 

and being the second-largest pharmaceutical 

market globally. With a 

$330 billion in revenue from organic 

chemicals alone and a workforce of 

over 725,000 as well as a pharmaceutical 

industry worth over $145 billion, 

the country stands as a global powerhouse 

in innovation and production. 

Driven by investments in sustainability, 

hydrogen technologies, and circular 

economy practices, China’s chemical 

sector is setting benchmarks for 

the future. On the other hand, China’s 

chemical industry accounts for 20 per 

cent of the country’s total industrial 

emissions and 13 per cent of its overall 

CO 2 

emissions. Therefore, a transition 

towards sustainable chemical 

production and a carbon-free industry 

is essential to achieving the country’s 

long-term goal of carbon neutrality 

and driving the global chemical value 

chain towards a low-carbon future. 

This transformation of a market which 

combines half of the total capital investment 

in the sector opens up opportunities 

for international suppliers. 

China: A global leader in chemicals and pharmaceuticals 

China is not just a production hub - it is the driving force behind global 

chemical innovation. Here is why: 

– Massive Domestic Demand: As the world’s largest manufacturer and exporter, 

China’s industries – ranging from automotive to pharmaceuticals 

– require vast amounts of specialty chemicals, polymers, and advanced 

materials. 

– Government-Led Innovation: Investments in green hydrogen, circular 

economy practices, and digital transformation have positioned China 

at the forefront of sustainable chemical production and policies like the

Compressors and Systems 


Turbo compressors reduce lifecycle costs 

Combining sustainability and efficiency 

Oil-free Class 0 compressed air with 

the smallest footprint – with the T 

series, BOGE once again demonstrates 

the benefits of the state-ofthe-art 

technology combined with a 

sophisticated concept. Significantly 

fewer components and doing completely 

without oil and lubricants 

guarantee low-wear operation. The 

clever design with high-speed motors 

and compression in several 

stages results in the best efficiency 

values and a reduced CO 2 

footprint. 

Compact, lightweight, quiet and particularly 

low-maintenance – these are 

just some of the positive features that 

characterise BOGE’s T series. It also 

sets new standards when it comes to 

efficiency. Each component has been 

optimised for its purpose. The series 

is divided into low-pressure and 

high-pressure versions. The LPT 150 

low-pressure turbo compressor, for 

example, supplies high-quality, absolutely 

oil-free compressed air between 

2 and 4 bar ü 

. This type of compressed 

air can be used for all sorts of 

purposes: for water and waste water 

treatment, for use in fish farms when 

combined with oxygen generators or 

for loading or unloading silo vehicles. 

With a rated output of 150 kW, the 

compressor produces a free air de-

and therefore weigh significantly less. 

ble screw compressors and therelivery 

between 31.3 and 42.9 m³/min. 

The T 220 turbo compressor could be 

seen as the “big brother” which generates 

oil-free compressed air between 

5 and 8 bar with a rated output 

of 220 kW. The free air delivery is between 

34.5 and 38.4 m³/min. This oilfree 

Class 0 compressed air produced 

is required in the pharmaceutical industry, 

for example, in the pharma 

industry, automotive as well as food 

and beverage industries. 

Clever design principle 

Adjusting the compressor to the compressed 

air requirements is essential 

for an efficient and economic compressed 

air supply. To achieve this, 

the compressor’s free air delivery 

must be adjustable. The adjustment 

range is determined by the system 

design as well as by counter-pressure, 

intake temperature and refrigerant 

temperature. Benefits particularly 

worth highlighting include a high 

degree of efficiency and economic 

operation with an adjustment range 

of up to 30 per cent. The heart of the 

T series is the innovative drive concept 

with high-speed motors and an 

air-cushioned drive shaft. The high- 

speed motors take up little space, allow 

high speeds beyond 100,000 rpm 

and are characterised by their very 

high energy density. The design features 

high-quality impellers on the 

ends of the drive shaft in connection 

with a diffusor and spiral housing. 

The titanium impellers are robust 

and allow low manufacturing tolerances, 

which results in higher speeds. 

Air bearings are characterised by 

virtually wear-free operation – without 

the need for oil. The drive shaft 

stabilises itself and requires neither 

additional energy nor lubricants. This 

is what sets them apart from conventional 

magnet and roller bearings. No 

lubrication is required for the drive 

mechanics. Therefore, there is no 

need for any oil circuit components, 

which, in turn, saves space. Thanks to 

the design, no oil or oil filter replacement 

is necessary. The fact that there 

are neither gears nor an oil system 

means that the compressors in this 

series stand out with particularly lowmaintenance 

operation. Another advantage 

compared with oil-free screw 

compressors is the exceptionally small 

footprint: The T series compressors 

are merely half the size of compara- 




fore weigh significantly less. Thanks to 

their compact size, these all-rounders 

are easy to integrate into intended 

operating areas and they save space. 

Special compression principle and 

cooling concept 

The technical components of the 

high-speed motor, air-cushioned 

drive shaft and compression system 

with several stages are perfectly synchronised. 

This means that losses can 

be reduced to a minimum. Practically 

100 per cent of air taken in by the 

compressor is compressed. The air 

taken in initially passes the intake filter 

and is partly used for cooling. The 

other part is directly guided into the 

first airend via an intake air box. The 

air warmed by cooling the motors is 

cooled again and then also used for 

compression. This is a particular advantage 

compared with conventional 

screw compressors in which the cooling 

air is directed into the compressor 

space where it warms up and then 

needs to be extracted again. 

Turbo compressors are characterised 

by compression in several 

stages. The LPT 150 has twostage 

compression, the T 220 has 

three-stage compression. Distribution 

across several airends results 

in mini mised compression temperatures. 

“The T 220’s three-stage compression 

optimises the efficiency of 

the compression process”, explains 

Jonas Begemann, BOGE Product 

Manager. “On the one hand, this reduces 

the temperature and on the 

other hand, mechanical losses are 

limited.” Using the integrated 3-level 

frequency converters, the volumetric 

flow rate can be adapted continuously 

to requirements. The frequency 

converter’s multi-level pulse width 

modu lation reduces rotor loss, thus 

allowing lower rotor temperatures. 

This means thermal loads can be additionally 

reduced. 

Quiet operation with economic and 

ecological benefits 

BOGE’s turbo compressors have 

even more benefits. They generate 

significantly less noise during operation, 

for example. Oil-free screw 

Fig. 3: The T 220 turbo compressor generates oil-free compressed air between 5 and 8 bar 

with a rated output of 220 kW. 

compressors generate sound pressure 

levels of 80 dB(A) during use, 

while the LPT compressor remains 

below this value at 73 dB(A) and the 

T compressor at 70 dB(A). Noise protection 

measures at the installation 

site are therefore not required. Users 

benefit from a reasonable purchase 

price, low opera ting costs and therefore 

signifi cantly reduced Total Cost 

of Ownership. With this sustainable 

design principle, BOGE ensures economic 

as well as ecological relief. 

Up to 90 per cent of the energy consumed 

can be used as heat, for example, 

because the T series models can 

be equipped with heat recovery as 

an option. This does not require additional 

space because all prerequisites 

are stan dard features. The heat 

from the compressed air process is 

emitted to the process water. External 

energy sources are therefore not 

required. The water reaches temperatures 

of up to 90 °C and is then 

available for further use, to heat offices, 

for example. Doing without oil, 

the high degree of energy efficiency, 

weight reduction and associated material 

savings result in the turbo compressors’ 

low CO 2 

footprint anyway, 

but this can minimise it even further. 

Increased reliability and 

maximum planning security 

The T series has been tried-andtested 

for its operational safety, offering 

maximum reliability. Since no 

gears, no fan motor, no oil pump and 

no lubrication systems are installed, 

they cannot wear out. The comprehensive 

maintenance concept promises 

planning reliability. The maintenance 

contract is initially valid for five 

years, but it can be extended several 

times and expanded by an additional 

component, creating Full Service. 

“With their maintenance agreement, 

customers also receive a guarantee 

for the motor-compressor unit”, 

Jonas Begemann explains. “In our Refurbishing 

Programme, we refurbish 

the whole unit instead of scrapping 

it.” Maintenance and wear parts are 

checked for the entire contract term 

of the Maintenance Package of five 

years and replaced as a precautionary 

measure if required. If a separate 

“no hassle” guarantee contract 

is signed, all costs will be covered in 

the event of a failure. The contracts 

can be extended by five years after 

a term of five years. This is followed 

by a maintenance contract that can 

be extended annually. It can also be 

complemented with BOGE’s “add-on” 

guarantee that is also available for 

yearly renewal. This results in system 

operators benefiting from increased 

planning reliability.

Biogas to biomethane: The role of 

compressors in enhancing renewable energy 

competitiveness 

Antoine Ferret 

The challenges posed by climate 

change and the pursuit of energy independence 

are considerable, both 

in Europe and across the world. 

Bio gas, produced through the anaerobic 

decomposition of organic 

materials, presents a viable solution 

to address these challenges. 

It helps reduce CO 2 

emissions and 

decreases dependence on imported 

energy sources, thus strengthening 

the energy sovereignty of the European 

Union. 

The full potential of biogas can 

be unlocked by upgrading it into 

biomethane, which can then be used 

for grid injection or green mobility. 

During biogas upgrading, carbon dioxide 

and gas impurities are removed 

to achieve high-purity methane. For 

the agricultural sector, it offers major 

benefits. Firstly, it enables the use of 

self-produced biomethane to power 

farming vehicles in an environmentally 

sustainable manner. Secondly, 

Methanepowered

work 

it facilitates the production of organic 

fertilisers recovered from fermentation 

residues, just as in combined 

heat and power (CHP) plants. 

However, biogas upgrading stands 

out with another benefit compared to 

CHP plants: the carbon dioxide, once 

lique fied, can also be put to use – for 

instance, in the food industry. 

Among various upgrading techniques, 

membrane technology is particularly 

notable for its high efficiency 

and minimal environmental impact, 

achieving methane concentrations 

exceeding 97 %. This approach utilises 

semi-permeable hollow fibre 

modules, which obviates the need for 

chemicals, water, or other auxiliary 

resources. 

Cost-effective climate neutrality: 

The role of compressors in enhancing 

renewable energy

technology is crucial to boost the competitiveness 

of biomethane within the 

energy market. The BAUER Group, a 

premium manufacturer certified to 

ISO 14001 standards with a strong 

commitment to environmental protection, 

plays a key role in supporting 

this development. For over 40 years, 

BAUER has been a leading company 

in high-pressure methane compression, 

particularly for use in vehicles, 

setting industry standards. About 10 

years ago, the family-owned company 

expanded its offerings to include 

solutions for low-pressure biogas 

compression, incorporating highly 

efficient screw compressors from 

its subsidiary ROTORCOMP ® . Screw 

compressors are ideal for meeting 

the specific pressure and flow 

requirements of biogas upgrading 

plants using membrane technology. 

Over 600 BAUER screw compressor 

systems have been successfully commissioned, 

with notable installations 

across Europe, the USA, and India. 

Harnessing years of accumulated 

experience, BAUER continuously optimises 

its “CNK product line,” which 

is manufactured in the company’s 

German and French plants to the 

highest quality standards. These compressors 

now handle flows of up to 

3,500 Nm³/h of biogas and pressures 

exceeding 16 bar. Designed for more 

than just industrial applications, the 

product line also serves research institutions 

and start-ups working with 

flow rates starting at 15 Nm³/h, supporting 

the development of future renewable 

energy solutions. 

Engineered with a consciously 

minimal design, the product line reduces 

the risk of downtime – staying 

true to the principle: “Fewer unnecessary 

parts mean fewer failures.” This 

reliability is essential for biogas upgrading 

plants, which operate around 

the clock to feed into the grid. The re-

EnviThan Gas upgrading technology 

in Friedland (DE): Efficiency and 

performance in focus 

The CNK420 compressor system, 

ope rating at the heart of the EnviThan 

gas upgrading plant of EnviTec Bio gas 

in Friedland, exemplifies this development 

philosophy. The EnviThan gas 

upgrading technology has established 

itself as a groundbreaking solution 

in the modern biogas industry. 

The CNK420 system in Friedland 

operates with an intake pressure of 

84 mbar, an outlet pressure of 10 bar, 

and delivers an impressive performance 

of 1,580 Nm³/h. 

With a frequency converter, the 

system can be reduced to as low 

as 600 Nm³/h. This not only simplifies 

plant start-up but also enhances 

adaptability to the production output 

of the biogas fermenter. The 

technolo gy behind this compressor 

unit prioritises what matters most: 

consistently compressing biogas 24/7 

while keeping energy consumption to 

a minimum. Particular emphasis was 

placed on minimising vibrations for 

instance, since they are a frequent 

cause of shutdowns in such highduty 

systems. On the CNK420, the requirements 

of the VDI 3836 guideline 

are fully met. Additionally, the inter- 

nal parameters of the biogas compressor 

unit were optimised through 

calculations and extensive testing to 

minimise energy consumption and 

maximise heat recovery efficiency. In 

Friedland, up to 80 % of the compressor 

unit’s energy consumption is returned 

as usable heat in the cooling 

water circuit. 

Thanks to its clean design, the 

system not only offers compact dimensions 

and high reliability but 

also easy access for maintenance. 

During the design process, considerable 

attention was given to 

streamlining maintenance duties to 

minimise downtime. One example is 

the oil separator tank and its swivelling 

mechanism, which significantly 

simplifies the replacement of the coalescence 

filter. 

With its modular setup, the compressor 

unit can be tailored to the 

operator’s exact requirements while 

maintaining the standardisation of 

the core machine. As a result: reduced 

costs, quicker delivery times, and improved 

quality. For instance, the CNK 

unit in Friedland is seamlessly aligned 

with the cutting-edge heat recovery 

concept of the EnviThan technology. 

As another illustration, the unit fits 

easily into standard ISO containers, 

like those of EnviThan. However, it 

can also be delivered as a turnkey solution, 

fully equipped with an outdoor 

housing and customisable sound insulation 

to accommodate the specific 

requirements of other operators onsite. 

A last example is the optional gas 

filtration in Friedland, which meets 

the strict requirements of the Envi- 

Than technolo gy for gas quality upstream 

of the membranes. With an 

oil content of less than 0.0025 mg/m³,

in the corresponding series of 

standards for functional safety are

Enhanced safety and efficiency 

through “artificial eyes” 

Dipl. Betriebswirtin Daniela Köhler, Dipl.-Ing. (FH) Gerhart Hobusch 

All industries face ever-growing technical 

demands, driving the need for 

continuous optimisation and energy-efficient 

advancements in production 

processes, including compressed 

air supply systems. Measurement 

technology is crucial in maintaining 

both the efficiency and safety of 

these systems. Cutting-edge intelligent 

devices deliver exceptional 

transparency, enhance supply reliability, 

and significantly reduce costs. 

Compressed air generation transforms 

electrical or mechanical 

energy into pneumatic energy, a process 

that comes with its own set of 

challenges, such as minimising energy 

consumption, maintaining stable 

pressure levels, ensuring production 

safety, and preventing contamination 

or leaks. Measurement technology 

tackles these challenges by delivering 

key data that can be used to 

monitor, control, and optimise system 

performance. 

Compressed air quality requirements 

in the industrial production 

are sometimes highly demanding. 

Manufacturing guidelines are becoming 

increasingly rigorous, often 

requiring certification and detailed 

docu mentation. Continuous monitoring 

across the entire process chain - 

from compressed air generation to 

distribution - is therefore essential to 

guarantee quality and safety in sensitive 

compressed air applications. 

In recent years, innovative compressed 

air solution providers have 

developed advanced measurement 

technology systems capable of fully 

monitoring entire compressed air 

networks. These systems aggregate 

data, conduct analyses, and generate 

evaluations, paving the way for continuous 

monitoring and optimisation. 

Every compressed air system 

generates an enormous volume of 

data every second. The challenge lies 

in capturing this data and converting 

it into meaningful information that 

can then be used to draw conclusions 

and derive actionable recommendations, 

providing tangible benefits for 

the compressed air station operator. 

While sensors in compressors 

and compressed air stations have 

been in use for years, not all sensors 

and monitoring systems are created 

equal. Digitalisation has revolutionised 

measurement technology. 

Modern compressed air systems utilise 

multi-sensors capable of transmitting 

real-time data to central control 

units or cloud platforms via IoT 

solutions. This allows for advanced 

trend analysis and predictive maintenance, 

reducing both costs and unplanned 

downtime. 

The right device in the right place 

A meaningful picture only emerges 

when intelligent sensors are strategically 

positioned to capture and interpret 

optimisation-relevant data. 

Purpose-specific individual sensors, 

strategically installed at key points 

within the compressed air system, 

act as “artificial eyes”, capturing targeted 

data points. This information is 

then transmitted to a central management 

system, where it is recorded, 

analysed, and visualised. The subsequent 

results can be accessed in the 

operator’s control system and forwarded 

to the compressed air provider’s 

cloud for intelligent remote 

monitoring. The station operator has 

the option to independently monitor 

their compressed air system and implement 

optimisation measures or 

leverage the provider’s expertise for 

real-time monitoring, allowing them 

to oversee and continuously optimise 

the compressed air supply as a tailored 

service. 

Data collection requires the use 

of suitable sensors. With advancements 

in sensor technology, modern 

measuring devices have become 

ever more compact and powerful. 

The latest generation of innovative, 

intelligent sensors allow flexible installation, 

even in challenging or

hard-to-reach places. These sensors 

are energy-efficient and deliver reliable 

data over extended periods. 

The complete system in view 

For comprehensive air system monitoring, 

it is recommended to install 

a range of measuring devices to accurately 

assess flow rate, process 

air, pressure dew point, intake and 

ambient air, and energy consumption. 

These devices should support 

process and environmental monitoring, 

ensure quality and energy oversight, 

and integrate all components 

into a highly efficient system. Quick 

and intuitive data analysis is equally 

essential to maximise efficiency and 

effectively meet documentation requirements. 

So, where are sensors needed, 

and why? When evaluating a compressed 

air system, it is crucial to begin 

at the intake point of the compressors. 

Room monitoring, often 

overlooked, plays a significant role, 

since intake and ambient conditions 

directly influence the compressed air 

station components and the quality of 

the compressed air that is produced. 

For instance, ambient temperature 

impacts the compressor’s operating 

temperature, which in turn affects 

its efficiency by altering the amount 

of electrical energy required to generate 

the desired volume of compressed 

air. In air-cooled compressors, 

the ambient air also determines 

the compressed air discharge temperature. 

Based on the measured conditions, 

adjustments may be needed for 

downstream compressed air treatment 

components, such as refrigeration 

or desiccant dryers. If key parameters 

exceed the limits accounted 

for during the system's initial design, 

this can lead to a degradation in compressed 

air quality - a particularly unfavourable 

outcome for sensitive applications 

such as tablet manufacturing, 

where overly moist compressed air 

can cause tablets to swell. Furthermore, 

and most importantly, contamination 

in the compressed air poses a 

health risk to the end consumer. 

A measuring device that monitors 

room and intake conditions is 

ideal for evaluating environmental

relevant data.

parameters, determining the operating 

conditions of compressed air station 

components, and assessing the 

moisture entering the system under 

the prevailing conditions. The operating 

and intake conditions relayed 

to the monitoring system offer valuable 

insights into the performance of 

the components. For instance, this 

data can help determine the necessary 

cooling and ventilation requirements 

within the compressed air station, 

such as managing recirculated 

air during the winter months. For certain 

processes, compressed air mass 

flow is required instead of volume 

flow. By measuring intake conditions, 

the mass flow can be accurately determined, 

dynamically adjusted, and 

supplied as required. 

Moreover, intake and ambient 

conditions are invaluable for error 

analysis and play a key role in applications 

such as flow rate control for 

blowers, vacuum regulation, and dynamic 

compensation for standardised 

volume flow. The measured 

parameters ensure that system malfunctions 

resulting from irregularities 

can be effectively prevented. 

One of the most important process 

parameters is the pressure at 

the transfer point, which is essential 

for optimising compressor control 


53



and determining whether production 

can continue safely. 

Further analysis options involve 

measuring media temperatures or 

pressures downstream from the compressed 

air generators, as well as upstream 

and downstream from the 

compressed air treatment process. 

The data obtained provides valuable insights 

into additional opportunities for 

compressed air supply optimisation. 

The next type of measuring device to 

include in a compressed air station is 

one designed to monitor flow rates. It 

is important to distinguish the operating 

principle of the measuring device 

and where it is used within the compressed 

air system. Installed directly 

downstream from the compressor, a 

flow rate measuring device based on 

the differential pressure principle is 

ideal for determining the generated 

flow rate, even at high temperatures 

and for air with an increased moisture 

concentration. In this case, the 

flow rate and total consumption are 

measured and calculated, while pressure, 

temperature, and flow velocity 

are also recorded. These devices typically 

operate within a measurement 

range of 1:10. 

A flow meter based on the thermal 

mass flow sensor principle has 

the advantage of covering a larger 

measurement range. However, it is 

more sensitive to contamination and 

should therefore only be used in the 

compressed air system downstream 

from compressed air treatment components, 

such as a refrigeration dryer. 

This device can also measure low flow 

rates, making it possible, for example, 

to detect leaks when work is not being 

carried out over the weekend. 

or upstream of sensitive applications. 

This setup enables, among other aspects, 

pressure differential monitoring 

throughout the entire compressed 

air treatment process and 

compressed air network, as well as 

ensuring compliance with required 

temperature levels. It also helps identify 

potential savings opportunities, 

such as lowering system pressure, 

scheduling timely filter replacements 

and more. In addition, the inlet and 

outlet temperatures of components 

can be monitored. Early detection of 

elevated inlet temperatures in treatment 

components effectively prevents 

overloading. An advanced version 

of this device also measures the 

pressure dew point, which reflects 

the moisture content of the compressed 

air, ensuring the air meets 

the required degree of dryness to 

maintain optimal quality. 

Energy monitoring 

The system is complemented by one 

or more measuring devices for energy 

analysis, such as a multifunctional 

network analyser designed to monitor 

the electrical energy supply. The 

analyser tracks the quality and reliability 

of the power supply while recording 

all critical values and metrics, 

making it an ideal system solution 

for modern energy data management, 

including compliance with ISO 

50001 standards. For operators who 

wish to use the device for energy 

data management, it can be optionally 

upgraded with MID (Measuring Instruments 

Directive) certification for 

legal metrology. This device also supports 

compressed air station operators 

in documenting energy savings 

and meets the requirements for verifying 

voltage quality, such as those 

outlined in EN 61000-2-4. 

Networking for an efficient system 

As previously mentioned, all of the 

intelligent sensors collect data in 

various ways and transmit relevant 

measurements from their respective 

locations via a data line to a compressed 

air management system, 

seamlessly integrating them into a 

unified network. This process enables 

Fig. 5: Cutting-edge technology ensures 

data is accessible anytime, allowing operators 

to maintain complete system oversight. 

Safety for production 

Adherence to specific limit values is 

of immense importance when using 

compressed air in production. With 

proper monitoring, failures and production 

downtime become a thing 

of the past. For this purpose, and to 

assess system pressure at various 

points, combined measuring devices 

that monitor pressure and temperature 

are the ideal choice. These can 

be installed at key locations, such as 

the inlet and/or outlet of components

real-time monitoring, data analysis, 

the creation of key performance indicators, 

and predictive maintenance. 

Any irregularities can be identified 

early on, and in the event of a fault, 

long-term data storage facilitates detailed 

problem diagnosis. 

In an optimally-designed compressor 

station, the integration of decentralised 

intelligence (component 

control) with centralised intelligence 

(a compressed air management system) 

establishes the perfect framework 

for seamless data exchange and 

analysis. This capability provides the 

operator with complete oversight. 

Using internal interfaces and the 

compressed air management system, 

they gain a clear, consolidated view of 

all critical performance metrics of the 

compressed air station. This is done 

in real time and on any device. Compressed 

air management systems can 

provide the following information: 

compressor operating data, faults, 

consumption behaviour, efficiency of 

the entire compressed air system and 

connected peripheral devices such as 

compressed air dryers, condensate 

drains, and treatment units, as well as 

ambient conditions and process data. 

This enables analysis of past anomalies, 

the prediction of future issues, 

and the proactive resolution of potential 

issues before they arise. The 

collected data can be retrieved from 

the compressed air management system 

for up to one year. 

This enables the operator to remotely 

monitor the status of the 

compressed air supply. Moreover, 

detailed reporting and effortless data 

downloads further streamline documentation 

processes. 

With the integration of advanced 

measuring devices and intelligent 

technology, previously hidden operations 

and processes can now be revealed 

and visualised. The goal is to 

achieve complete transparency, providing 

the critical insights needed to 

create accurate predictive models. 

Cutting-edge advancements are making 

this a reality, steadily setting high 

supply reliability as the new standard.

Acoustic Emission Testing 

Sound never lies 

Rainer Semmler, Hermann Schubert 

The German Industrial Safety Regulation 

(BetrSichV) allows operators 

of pressurized equipment, under 

certain conditions, to conduct 

their mandatory regular inspections 

using acoustic emission testing. 

Acoustic Emission Testing (AT) is an 

economical and efficient alternative 

to traditional visual and hydrostatic 

testing methods. TÜV SÜD outlines 

what needs to be considered. 

In AT, acoustic emission sensors are 

attached to the pressure vessel or 

machine parts being tested. These 

sensors capture the transient elastic 

waves generated by, for example, 

plastic deformation, crack propagation, 

erosion, corrosion, impact, and 

leakage — all of which can occur in 

components under stress. One significant 

advantage of this method is 

that the source of these elastic waves 

can be accurately located, making 

fault detection easier. While AT has 

long been used in other industries, 

advancements in sensor technology

dustries, which have high safety and 

reliability requirements for all utilized 

vessels. 

Typical facilities, such as those 

used in the production of polymer 

resins for the automotive or packaging 

industries, consist of numerous 

vessels where processes like heating, 

cooling, and mixing of raw materials 

are controlled under specific process 

production interruption required for 

emptying the vessels, refilling them 

with water, and then drying them is 

eliminated. The drying process alone 

can take one or two days, and any remaining 

liquid can lead to vessel corrosion. 

If the operator can avoid this 

downtime, the costs associated with 

the inspection are reduced by the 

equivalent daily revenue. 

parameters, such as pressure. Inspection methods requiring 

These processes can only function 

correctly with a properly maintained 

and regularly inspected system. Previously, 

inspections were performed 

using visual internal examinations 

or hydrostatic strength tests. These 

production shutdowns also place additional 

strain on all system components 

due to repeated start-ups and 

shutdowns, as well as the associated 

pressure and temperature fluctuations. 

This can shorten the equipment’s 

methods often required production 

life span. Additionally, the nec-

workflows. 

essary replacement of all seals after 

opening a vessel adds to the inspection 

costs. Materials and assembly account 

for approximately 2.5 percent 

of the total inspection costs — an expense

the risk of unexpected downtime due 

AT offers several advantages in this 

context, particularly compared to hydrostatic 

testing. For example, the

When assessing the cost-effectiveness 

of an inspection method, it is 



Sensors 

important to consider not just the direct 

inspection costs but also the associated 

efforts, resource consumption, 

and disposal of used testing 

materials. The significantly shorter 

downtime alone results in substantial 

cost savings. While a traditional 

inspection may require five days of 

downtime, an AT inspection is typically 

completed within a day. If downtime 

costs are estimated at 30,000 

Euros per day, the total savings can 

easily reach six figures. 

Another cost advantage of AT is 

that multiple inspections can be performed 

simultaneously, requiring 

fewer personnel. This reduces overall 

inspection time, making planning 

and organization easier. Components 

that raise concerns can 

immediately undergo further investigation 

using other non-destructive 

testing methods. Integrative testing 

approaches make maintenance 

not only more cost-effective but also 

more sustainable. 

A recognized method 

Annex 2, Section 4 of the BetrSichV 

outlines the requirements for the recognition 

of AT in mandatory pressurized 

equipment inspections. The 

inspection concept must be approved 

by an accredited supervisory body, 

confirming that AT delivers safety results 

equivalent to other conventional 

methods. This approval also serves 

as the basis for inspecting pressure 

vessels and their components during 

operation — one of AT’s key advantages. 

Machines suitable for AT inspection 

include rotating equipment 

such as pumps, turbines, compressors, 

and motors. 

Predictive maintenance with AT 

AT methods commonly use piezoelectric 

sensors. These sensors generate 

an electrical charge when subjected 

to vibrations, capturing sound waves 

caused by material changes. Unlike 

pressure testing, AT detects these deviations 

early — before leaks occur. 

Cracks or corrosion can also be identified 

through characteristic acoustic 

emission signatures. Thus, AT supports 

predictive maintenance, allowing 

for targeted planning of maintenance 

measures. This reduces the 

risk of unplanned downtime as well 

as emergency repair costs. Another 

financial advantage comes from the 

extended lifespan of all components 

with proactive maintenance. Once 

digitized, the electrical signal can be 

transmitted, processed, and analysed 

through any digital system. 

This method is not only suitable 

for recurring inspections but also for 

general functional checks of pressure 

vessels and tanks. It utilizes the 

acoustic emissions of the material 

within the vessels, eliminating the 

need for emptying and refilling with 

alternative test substances. A minimum 

filling level is required, but even 

hard-to-reach or underground ves-

Conclusion: numerous benefits of AT 

Using AT as an alternative to traditional 

inspection methods for pressure 

vessels and tanks offers several 

advantages. The primary benefit is 

that inspections can be performed 

during regular operations, making 

them significantly more efficient in 

terms of organization, time, and cost. 

Additionally, sensors detect material 

changes much earlier — before leaks 

even occur. TÜV SÜD calculates the financial 

advantages and assists with 

implementation.

Piezoelectric Sensors in AT 

– The sensors are highly sensitive and detect even the smallest changes 

and vibrations. 

– Their wide frequency range makes them versatile – they can be used for 

various AT inspection scenarios with different materials. 

– Piezoelectric sensors instantly convert displacement into electrical 

signals, making them highly dynamic. They precisely capture time 

sequen ces without needing additional signal amplification. 

– Their small size and lightweight design make them ideal for complex 

structures or difficult-to-access areas. 

– The sensors withstand significant mechanical stress. However, their 

functionality may be impaired in very high-temperature environments.

Measurement of hotspot temperatures: 

Reliable measurement in stators 

Günter Grommes 

DIN EN 61800-5-1 plays an important 

role for temperature measurement 

in engines, particularly in the context 

of electric high-performancedrive 

systems with an adjustable 

speed. This DIN standard forms a 

comprehensive framework for safe 

and reliable temperature measurement 

in engines within electric drive 

systems. It ensures that temperature 

monitoring meets the required 

KTY. Here, manufacturers like to apply 

heat-shrink tubing to the measuring 

point as insulation materials 

with single or multiple layers. Given 

the increased requirements of the 

standard, this design type only partially 

meets the more demanding requirements 

for the stipulated insulation 

system. The heat-shrink tubing 

is made of PVDF (polyvinylidene fluoride). 

PVDF is part of the per- and 

safety standards and therefore contributes

subject to criticism due to their persistence 

in the environment.

sensors for measuring hotspot temperatures 

in the engine and motor industry. 

The task was to ensure that 

the new standard requirements for 

electric strength and the insulation 

system in the power drives were also 

met by the temperature sensors. 

Fig. 1: Example of a wound stator with a rotor insert 

The key requirements here were: 

– The use of a platinum measuring 

resistance Pt1000 according to IEC 

60751 

– Ensuring the withstand electric 

strength as a permanent electrical 

insulation between the sensor 

and the engine winding (standard 

requirement DIN EN 61800-5-1) 

– Ensuring surge voltage safety to 

resist short-term voltage peaks or

Impressive solution for the industry 

The innovative PGT solution contains 

a thermoplastic polymer developed 

especially for this product. This polymer 

is used to injection-mold the 

sensor measuring head using an injection 

molding process that has also 

been newly developed. This means 

that PVDF heat-shrink tubing is no 

longer needed. Due to the high number 

of units on the market, the injection 

molding process is very suitable 

for producing even very high quantities 

with a reproducible sensing element 

position in the sensor head to 

maintain the insulating system. Currently, 

the sensors are produced in a 

PGT 4-fold injection molding tool. 

The following new product features 

have been implemented through this 

new process: 

Fig. 4: Customer-specific sensor version 

– UL-approved components 

– Free choice of design for the sensor 

head (standard diameter 3 to 

4 mm, length 16 to 18 mm)

and an electric strength of 

up to 13 kV 

– Thermoconductive sensor head 

made of thermoplast (2 to 6 W/mK) 

– Very high shock resistance and vibration

– Designable withstand electric 

strength in the range of 4 to 10 kV 

according to DIN EN 61800-5-1 

– Surge electric strength according to

– Temperature approval for all insulation 

systems A, E, B, F, H, N (105 

to 220 °C)

the sensor module < 10 pC at 

1.5 × UPD (15 sec.) 

– Temperature range -40 to +240 °C 

– Rapid sensor head reaction time/ 

response time of the sensor head 

in the range of a few seconds (t90) 

– Use of a Pt1000 measuring resistance 

as an SMD design type or as a 

wired version (JUMO) 

Thanks to the innovativeness of PGT, 

which is integrated into the JUMO 

group, the engine market now has 

temperature sensors available that 

meet not only the current requirements 

of the DIN EN 61800-5-1 standard 

but also the increased requirements 

of the future standard. The 

sensors are currently being produced 

in high quantities for industrial, but 

also vehicle engines. They are used 

to safely detect temperature increases 

in or on engine winding packages. 

Measurement is performed directly 

on the live conductors. 

The newly developed technology 

of plastic sheathing for sensitive 

sensing elements is also used for 

solutions on a cross-industry basis. 

In addition to processing analogue 

measuring resistances, digital temperature 

sensors can also be formed 

in this manner.

Automation with multi-couplings: 

Process optimisation from steel processing 

to the automotive industry 

Process automation is a crucial 

success factor in modern industry. 

Multi- couplings enable quick, 

secure, and reliable connections of 

various media circuits. An increasing 

number of companies are recognizing 

the enormous potential for 

streamlining operations, enhancing 

process safety, and improving 

workplace safety through the use 

of multi-couplings. Depending on 

the application area and specific requirements, 

different coupling systems 

are employed. 

What can multi-couplings do? 

In industries such as automotive and 

steel, where high production rates, 

reliability, and precision are required, 

multi-couplings have secured a vital 

role. Essentially, they consist of a 

fixed half and a loose half (or a supply 

side and a consumer side). The 

fixed half contains an arrangement 

of coupling elements specific to the 

lines, while the loose half houses the 

corres ponding nipple elements. During 

the coupling process, the two 

halves connect reliably. 

The use of multi-couplings and docking 

systems offers numerous advantages: 

– Efficiency Improvement: By simultaneously 

connecting and disconnecting 

multiple lines, changeover 

times can be reduced. This enhances 

productivity and allows for 

higher utilization of equipment. 

– Safety: The fixed arrangement of 

coupling elements and the precise 

alignment of lines eliminate the 

risk of mix-ups. This improves operational 

safety and protects both 

employees and the equipment and 

its processes. 

– Reliability: The robust design and 

dependable connections reduce 

maintenance efforts and increase

hydraulically, or electrically. Often, 

a push or pull mechanism is employed, 

in which the coupling halves 

are brought together or separated 

with a defined force. The separation 

forces that occur during operation 

are absorbed by additional mechanical 

locks. These ensure that 

the coupling plates remain securely 

connected even under full operating 

pressure. Multi-couplings with such 

build in actuation ensure a fast and 

reliable change of tool connections. 

They are also used in test benches, 

for instance in e-mobility applications, 

such as connecting large electrical 

plugs to electric motors. In

to change batteries quickly. 

ling systems integrated into hot strip 

mills must withstand extreme conditions 

and ensure reliable media supply. 

An example of this is a plate-style 

multi-coupling for coilers, which wind 

the hot sheet metal after the rolling 

process. The quick and secure connection 

of cooling media ensures optimal 

cooling of the mandrel, thereby 

guaranteeing the quality of the 

final product. The demands on such 

systems are high, as they must enable 

rapid changes of the coilers while 

maintaining high reliability.

disconnection of various media such 

as fuel, coolants and lubricants. They 

also serve as an interface between 

self-propelled workpiece carriers and 

the systems to be supplied, enabling 

efficient and flexible material flow 

organisation. By minimising set-up 

times and ensuring a long service life, 

multi-couplings help to optimise testing 

processes and increase system 

availability. 

Tool changers for industrial robots 

Tool changers are also used in the 

automotive industry. They enable the 

fast and precise exchange of tools 

on robots without the need for manual 

intervention, ensuring the secure 

connection of fibre optic control 

lines, welding current, or pneumatic 

and hydraulic systems. With tool 

changers, robots can flexibly switch 

between different tasks, thereby increasing 

productivity. Typical application 

areas are found in body construction, 

where industrial robots 

perform various tasks such as welding, 

gluing, or clinching. Tool changers 

are also used as handling tools in 

palletizing applications. 

Challenges and specific features of 

automated multi-couplings 

Automated multi-couplings face a 

range of specific design challenges. 

On the one hand, they must be capable 

of compensating for positioning 

inaccuracies in all axes. Floating bearings 

enable flexible adaptation in this 

regard. Moreover, ensuring the secure 

separation of media flows is of great 

importance. The locking mechanism 

must be able to counteract the separation 

forces. 

Another challenge lies in the combination 

of electrical connections and 

liquid media. Clean-break coupling elements 

are particularly suitable for 

this purpose, as they ensure safe disconnection 

and connection without 

residual leaks. This clean-break technology 

is a significant contribution not 

only to occupational safety but also 

to environmental protection. To optimize 

plant processes, precise monitoring 

of the coupling state is also essential. 

Proximity sensors and limit 

switches provide the necessary information 

to the plant control system.

The ELT by the European Southern 

Observatory (ESO) has been under 

development since the program’s 

initial approval in 2012, and it will be 

the largest visible and infrared light 

telescope in the world when it is put 

into operation by the end of the decade. 

Thanks to its size and suite of 

cutting-edge instruments, the ELT will 

be capable of a wide range of scientific 

operations and has been designed 

to identify earth-like planets around 

other stars (see elt.eso.org). 

The largest mirror ever made for 

an optical telescope 

At the heart of the ELT lies the M1 

primary mirror which will make the 

project’s research possible. With a diameter 

of 39 meters and a light collecting 

area of 978 square meters, it 

will gather 100,000,000 times more 

light than the human eye. To achieve 

this, the M1 mirror consists of 798 

hexagonal elements that are aligned 

with extremely high precision on a 

nanometer level. As a result, these 

elements need to meet very high demands. 

Each 1.5-meter-diameter element 

is made of a glass-ceramic material 

with very low thermal expansion and 

features a coating primarily made

surface 

100,000,000 times more lightsensitive 

than the human eye 

of silver. To ensure maximum sensitivity, 

the coating needs to be reapplied 

every 18 months. This means 

removing, stripping, recoating, and 

reinstalling two elements every day 

throughout the ELT’s lifespan. For the 

M1 primary mirror, the entire recoating 

process takes a year to complete 

before starting over. The successful 

operation of the ELT therefore 

depends on cutting-edge solutions 

for reliable and continuous maintenance, 

including a washing and stripping 

plant that prepares the mirror 

elements for the recoating process. 

Designing a washing and 

stripping plant 

The plant was designed and constructed 

by Swedish industrial consultancy 

firm Fagerström Industrikonsult AB 

which was awarded the contract in 

2020. While the original tender stipulated 

a solution that would require 

the mirror element to be moved between 

different maintenance stations, 

Fagerström suggested a different 

approach. In order to protect the 

very valuable mirror elements and 

simplify the process, the company 

developed an all-in-one solution that 

completes all five washing and stripping 

stages:

sharper images of cosmic objects than ever before.

Prewash 

After the mirror element has been 

installed on its maintenance station, 

it is then prewashed with water to 

remove any loose debris. It is then

washed with a neutral detergent solution 

that targets fatty deposits and 

any other remaining contamination 

before it is rinsed again with deionized 

water. 

Stripping 

The old coating is dissolved using a 

chemical solution that includes sulfuric 

acid and cerium sulfate. The concentrations 

vary depending on the 

condition of the mirror element. 

Final Rinse 

To prepare the mirror element for recoating, 

the bare glass-ceramic material 

is rinsed once again with deionized 

water until the conductivity of 

the run-off reaches a defined value. 

Drying 

Any remaining residue or contamination 

is removed with an air knife. 

QC Control 

Prior to recoating, the mirror element 

is meticulously scanned to make sure 

it meets purity standards. 

While an all-in-one washing and 

stripping plant provided various benefits 

such as a smaller footprint and 

higher efficiency, it also posed challenges. 

By relying on one main station 

for all washing and stripping 

stages, it was essential to avoid 

cross-contamination of the different 

media as this could not only affect 

quality but also the use of resources 

– chemical residue would require additional 

flushing, and left-over water 

could dilute the chemical solution. 

Fagerström approached this issue 

by constructing separate skids 

for process water, detergent, and 

the chemical solution, and by using 

gravity drains with reversible pumps

to prevent contamination after each 

stage. At the same time, the engineers 

had to design a wastewater 

treatment system that could separate 

the silver particles from the dissolved 

mirror coating and therefore 

increase the service life of components 

such as filters. 

Finding the right flow solutions 

During the 5-year planning and construction 

process, selecting the optimal 

piping systems was a key concern 

as safe and reliable fluid handling 

is mission-critical for the plant. The 

Swedish industrial consultancy firm 

chose GF Piping Sytems, a Swiss flow 

solutions provider with decades of 

experience in handling ultrapure water 

and harsh chemicals, as a partner 

throughout the project. 

After an extensive planning phase 

and material tests, a complete solution 

for Process Automation was selected, 

consisting pipes as well as 

manual and automated valves from 

the PROGEF family, an industrial polypropylene 

(PP) welded system for 

safe fluid handling in critical applications. 

The Polypropylene used by the 

Swiss company is a very durable material 

with a high chemical resistance 

against a wide range of acids, bases, 

and solvents, and is ideally suited for 

aggressive media like sulfuric acid. 

In addition, the option of infrared 

fusion was a deciding factor for 

Fagerström. IR fusion contributes to 

safe and leak-free pipe connections 

with a machine-controlled process 

that ensures repeatability and full 

traceability. Importantly, the fusion 

process produces very small welding 

beads that not only allow optimal flow 

within the pipes but also minimize 

dead spaces, which further reduces 

the risk of cross-contamination. 

GF Piping Systems also supplied 

critical measurement sensors for 

para meters including level, pressure, 

and temperature. Monitoring these 

parameters ensures a reliable operation 

but is equally important for understanding 

the health of the washing 

and stripping plant. For example, 

measuring the pressure-drop across 

filters provides insights into their condition, 

while blockage and leak detec- 


tion reduces the risk of damaging 

pumps and valves. 

Due to space constraints 

and the fact that shorter piping 

systems are another proven 

strategy for reducing crosscontamination, 

custom components 

for the skids were required. 

Here, the Swiss supplier 

was able to modify the assembly 

of its valves to meet the requirements. 

Looking back at the project, 

Carl Johan Fagerström, CEO of 

Fagerström Industrikonsult AB, 

comments: “From the outset, 

we were able to identify and 

address the needs of the customer. 

By assisting throughout 

the entire process, from material 

selection to custom components, 

GF Piping Systems has 

done the same for us. When designing 

one-of-a-kind machines, 

suppliers with a deep understanding 

of the project are crucial 

for success.” 

Peter Ernström, one of the 

Process Automation Specialists 

at GF Piping Systems who 

accompanied the entire project, 

adds: “Fagerström is pushing 

the boundaries of innovation 

with its unique solution 

for the world’s biggest optical 

telescope. Our extensive experience 

with process automation 

for chemical applications 

allowed us to support the consulting 

company throughout 

every project phase and supply 

a bespoke solution to turn their 

vision into reality.” 

After completing the construction 

phase, the next step 

consisted of disassembling and 

shipping the washing and stripping 

plant to Chile. The main 

mirror elements are expected 

to be installed in 2027, and 

the ELT’s first scientific verification 

is targeted for 2028. Once 

operational, the washing and 

stripping plant will play a role in 

advancing astrophysical knowledge, 

enabling a deeper exploration 

of the Universe and providing 

sharper images of cosmic 

objects than ever before.

Separation 

Sand treatment with spin cycle 

Nils Engelke 

In sand preparation, Reithelshöfer 

GmbH saves over 90 percent process 

water by using a decanter centrifuge 

and at the same time reduces 

investment and operating costs. 

If you were to ask people in the street 

today which raw materials they consider 

to be the most important, hardly 

anyone would mention the word 

“sand”. Sand is worldwide one of 

the most basic raw materials. Gigantic 

quantities are needed every year 

to build houses, airports, roads and 

much more, for example. And since 

sand is not just sand and cannot be 

removed from the ground in the desired 

quality, companies such as 

Sandvertriebs- und Verwertungsgesellschaft 

mbH & Co. KG of the Reithelshöfer 

Group near Nuremberg 

process these resources. Tonnes of 

gravel and sand are extracted every 

day, and of course it is also a question 

of economical and resource-saving 

production. Efficient use of water 

plays a decisive role in this. The 

company has gained an enormous 

competitive advantage since they began 

using a Flottweg decanter centrifuge 

for washing water treatment: 

The new technology has reduced the 

fresh water requirement from 350 

cubic metres per hour to just 20 cubic 

metres per hour. 

of fresh water that has to be continuously 

supplied, the wash water is 

separated from the washed-out particles 

and reused. Consequently: The 

more precious water that can be separated 

and purified from the residual 

mass, the more efficient the entire 

manufacturing process is – from an 

economic as well as an energetic and 

ecological point of view. 

Traditional sludge dewatering 

reaches its limits 

Traditionally, washing water is purified 

in two steps, which are still used 

in many companies today: First, the 

coarse particles are separated from 

the water via the sedimentation process, 

for example in an oblique clarifier. 

A vacuum band filter is then often 

used, which separates a further proportion 

of the water from the sludge 

with the addition of a flocculant. In 

view of today’s technological standards 

and ever-increasing production 

volumes, this type of sludge dewatering 

is no longer efficient enough. 

To make matters worse, new 

regu lations are being constantly introduced 

and rising costs are forcing 

producers to keep tailings piles as 

small as possible and to reduce the 

amount of fresh water to a minimum. 

Adopting innovative procedures 

Those responsible at the sand processing 

company Reithelshöfer 

GmbH near Nuremberg were also 

concerned about the recovery of water 

from sand processing and about 

the costs of large spoil heaps - for 

which it is now almost impossible to 

obtain permits - and about cost-effectiveness. 

The company has always 

been innovative in the way it tackles 

challenges, and several years ago its 

technicians were convinced that special 

attention should be paid to the 

treatment and purification of wash 

water. The people then made a decision 

that was rather unusual in the 

industry, but quite innovative. In order 

to achieve a much more efficient 

treatment of the sand washing water 

and to avoid losing large quantities 

of water with wet sludge on the evergrowing 

spoil heaps, they opted for a 

process that has long been standard 

in other industrial sectors: decanter 

centrifuge technology. 

Flottweg’s decanter centrifuge 

was chosen in 2003. This company 

from Vilsbiburg in Bavaria is a pioneer 

in centrifuge technology and offers 

machines for separating liquids 

from solids for almost every conceivable 

application. Reithelshöfer uses 

Separation in stages 

Huge amounts of water are required 

to extract sand. Finally, the extracted 

material must be separated into its 

components, including gravel, sand, 

clay and coal, to name just a few. 

With sieves and the use of a lot of water, 

soluble parts are flushed out and 

the valuable material is separated 

into different grain sizes via ever finer 

sieves - until exactly the sand and 

gravel grain size is obtained as required 

for different applications. One 

of the major challenges in the treatment 

process is the amount of water 

required. To minimize the amount 

Fig. 1: By using the decanter technology, the fresh water consumption of the plant was massively 

reduced. 



Separation

material per hour.

without any problems. 

the Flottweg Z92 model, which 

enables true parallel operation 

with its high separation capacity 

of up to 15 metric tons per hour. 

The advantage: During sand 

preparation, the centrifuge separates 

so much clean water from 

the used wash water that no runon 

for washing water cleaning is 

required afterwards. The decanter 

centrifuge is adjusted so that 

particles smaller than 25 µm are 

also separated from the water. 

The centrifuge also scores 

points with further decisive advantages 

over other technologies. 

In contrast to chamber filter 

presses or belt filter presses, several 

of which would be needed in 

parallel to achieve approximately 

similar results, a single centrifuge 

is sufficient at Reithelshöfer. 

As a result, much less steelwork 

was required for the structure 

and the overall outlay in terms 

of procurement and installation 

was significantly lower. At the 

same time, the costs for maintenance 

and operation of just one 

machine are significantly lower. 

Since the decanter can dewater 

the sludge to up to 55 percent 

dry solids in just one pass, intermediate 

storage of the thickened 

sludge in a holding tank is also 

no longer necessary. Due to the 

high degree of dewatering, the 

residual sludge can be transported 

directly from a bunker located 

under the machine with the 

wheeled loader. 

The fact that centrifuge 

technolo gy is a worthwhile investment 

is particularly noticeable 

in fresh water consumption, 

both economically and environmentally: 

Due to the significantly 

higher separation compared to 

other processes, much more water 

is returned to the production 

process. With traditional separation 

methods, a fresh water 

supply of no less than 350 cubic 

metres per hour was required. 

With the use of the centrifuge, recovery 

is significantly more efficient 

and only 20 cubic metres of 

fresh water are required. 

Potential savings through readjustment 

and low maintenance 

For optimum performance, in 

order to maintain significant 

savings in water and space for 

overburden, the centrifuge must 

be constantly adjusted according 

to the consistency of the sludge 

to be dewatered. At the heart of 

this is the energy-saving Flottweg 

SIMP drive. This drive controls 

the differential speed between 

the decanter bowl and the internal 

screw according to the prevailing 

screw torque. The drive 

shaft of the gearbox is operated 

by a frequency-controlled motor, 

which allows the speed to 

be optimally adjusted. A second 

(frequency controlled) motor 

drives the decanter drum so that 

the mass moment of inertia to 

be overcome and regulates the 

bowl speed as required. Changes 

in the feed have an impact on the 

screw torque, since the screw 

must convey different amounts 

of solids which leads to different 

loads. The adjustment of the 

differential speed can be accomplished 

very easily and quickly 

with the SIMP-Drive, thus ensuring 

a consistently high dewater-

ing of the sludge. This drive and 

other components of the machine 

ensure that the client can 

calculate with very low maintenance 

costs. The closed system, 

which is designed for maximum 

load, runs autonomously and is 

largely maintenance- and wearfree. 

“Flottweg’s decanter centri - 

fuge has been in use at 

Reithelshöfer for many years 

now. The investment has paid off 

many times over in terms of water 

savings alone. And despite 

the harsh conditions and continuous 

use, the centrifuge has performed 

its duties without complaint 

to this day. Even during 

maintenance, there is not much 

more to do than occasionally 

changing a set of V-belts and replenishing 

oil for central lubrication. 

The decision to use the decanter 

centrifuges has more than 

paid off for us”, concludes Stefan 

Köhn, Mana ging Director of M. 

Reithelshöfer GmbH.

Direct sprayer 

Tank cleaning for agitators 

Precision cleaning instead of flooding: 

Efficient tank cleaning with minimal 

water waste 

From softdrinks to toothpaste: 

Cleaning tanks with agitators presents 

a major challenge for plant operators. 

The undersides of agitator 

blades are often difficult to reach 

and remain in the spray shadow, 

making full cleaning difficult. This 

results in inefficient processes, 

high water consumption, and excessive 

use of chemicals. The new 

GEA Direct Sprayer DS 25 provides 

a paten ted solution that delivers 

targeted cleaning while conserving 

valu able resources. 

The challenge: Cleaning tanks 

with agitators 

The cleaning requirements in the 

food and beverage industry are constantly 

increasing. High hygiene 

standards, prevention of product 

contamination, and efficient resource 

management are critical for plant 

operators. Tanks with rotating agitators, 

baffels and pipes pose a particular 

challenge: the undersides of 

the agitator blades often remain in 

the spray shadow, making them hard 

to clean with conventional cleaners. 

As a result, operators face inefficient 

cleaning cycles, increased water consumption, 

and a higher demand for 

cleaning chemicals. 

A patented solution 

GEA has developed the Direct Sprayer 

DS 25 to specifically target the undersides 

of agitator blades, eliminating 

spray shadow without interfering with 

agitator movement. “Previously, operators 

often flooded these tanks up to 

the height of the agitators to ensure 

complete cleaning – a costly and unsustainable 

approach,” explains Jana 

Zimpel, Product Sales Manager for 

Fig. 1: GEA Direct Sprayer DS 25 with full cone spray. Source: GEA 

Cleaning Technology at GEA’s Separation 

and Flow Technologies division. 

“With our new technology, we clean 

precisely where needed, saving large 

amounts of water and chemicals.” 

Innovative technology for 

maximum efficiency 

The Direct Sprayer DS 25 is integrated 

directly into the tank wall. Its patented 

design allows for a flush-mounted installation 

that does not restrict agitator 

movement. The key innovation is 

the movable valve plate, which opens 

right into the cleaner when activated 

to produce a precise spray pattern. 

Through a gap, the cleaning liquid 

is released as a full-cone spray – an 

important advantage over conventional 

spray cones, which often leave 

a hollow space in the center. This in-

Sprayer DS 25 to specifically target the 

undersides of agitator blades, eliminating

novation ensures uniform coverage and efficient 

residue removal. 

toothpaste production, where thick pastes 

are processed, effective cleaning is crucial. 

Maximum spray force and reach 

Sustainability and resource conservation 

One of the standout features of the Sprayer 

is its powerful mechanical cleaning action. 

With a spray force of up to five kilograms, 

the full-cone spray effectively removes even 

stubborn residues. Its cleaning reach of up to 

five meters makes it ideal for large tanks, ensuring 

that all critical areas receive thorough 

cleaning. 

“A major advantage over traditional retractors, 

which often have a hollow cone in 

the middle or operate with a fan spray, is the 

flexible positioning,” explains Jana Zimpel. 

“Our sprayer opens inward the cleaner and 

produces a precise full-cone spray, whereas 

conventional systems often provide only a 

limited fan spray. This allows us to clean every 

area in the tank efficiently and sustainably.” 

The inward-opening valve plate ensures that 

the agitator mechanism remains unaffected. 

Yogurt production: 

84.5 % less water consumption 

A practical example demonstrates the potential 

of this new technology. A typical yogurt 

production tank is six meters tall and three 

meters in diameter, with multiple agitator 

blade levels. In this example, there are three 

levels up to four meters in height. Previously, 

such tanks had to be flooded with up to 29 cubic 

meters of cleaning liquid – a process that 

took two hours. 

“With the new system, we would integrate 

three sprayer units into the tank wall, precisely 

cleaning the undersides of the agitator blades,” 

says Zimpel. “This saves 84.5 % water and reduces 

cleaning time by 87.5 % – from two hours 

down to just 15 minutes.” 

Versatile applications: 

From yogurt to toothpaste 

The Direct Sprayer DS is designed for use in 

the food, beverage, dairy, and pharmaceutical 

industries. It is particularly effective in demanding 

applications, including: 

– Yogurt production: Tanks with multiple agitator 

blade levels require precise cleaning 

at different heights. The sprayer significantly 

reduces cleaning effort. 

– Toothpaste manufacturing: In the home 

and personal care (HPC) industry, tanks 

with multiple agitators are common. In 

“The advantages of our new technology extend 

beyond cleaning efficiency,” emphasizes 

Jana Zimpel. “We drastically reduce water consumption, 

which translates into lower costs 

for our customers and a reduced environmental 

impact.” 

Beyond water savings, the targeted use of 

cleaning agents reduces chemical waste and 

improves the overall CO 2 

footprint of plant 

operations. 

The sprayer can be easily integrated into 

existing tank systems. Variants designed to 

meet 3-A sanitary standards are already in 

development to enhance global applicability. 

Conclusion: 

precise cleaning saves resources 

With the Direct Sprayer DS 25, GEA introduces 

a groundbreaking solution for industrial 

cleaning. The patented fluid dynamics ensure 

targeted spray coverage, minimize water and 

chemical consumption, and enable more efficient 

tank cleaning. 

“Our goal is to provide plant operators 

with the best possible technology to meet 

the highest hygiene standards while protecting 

the environment,” concludes Jana Zimpel. 

“With the Direct Sprayer, we’ve taken a major 

step in that direction.”

Drives 

Travelling and lift drives from a single source 

Compactness – this has always been 

one of the decisive criteria for the 

industrial gear units from NORD 

DRIVESYSTEMS. For this reason, 

the gear stages of the MAXXDRIVE ® 

series were previously always arranged 

in a staggered arrangement. 

This is an optimum gear geometry 

in applications such as mixing technology. 

The drive specialist has now 

broken with its exclusive commitment 

to compactness – with a special 

drive solution for the lifting gear 

of cranes. The new MAXXDRIVE ® 

XD is characterised by an extended 

centre distance and therefore optimally 

meets the specific requirements 

of lifting gear applications. 

These are offered as three-stage 

and four-stage parallel gear units. 

A U-shaped arrangement is usually 

used for the lifting gear drives of 

cranes. The motor and the cable 

drum are located on the same gear 

unit side. In order to achieve this, the 

gear unit requires a certain centre 

distance. This was now implemented 

by the developers at NORD. They arranged 

the gear stages of the new 

MAXXDRIVE ® XD horizontally in a row, 

thereby extending the centre distance 

by 35 percent in comparison to 

the proven compact product series. 

“We have listened very carefully to 

the demands of the market”, explains 

Jörg Niermann, Head of Marketing, 

“and are now giving our customers 

the opportunity to purchase running 

gear and lifting gear drives for cranes 

from a single source.” 

The elongated arrangement of 

the gear stages enables the gear 

unit to be dimensioned with a precise 

mechanical fit and sufficient 

centre distances. “We have therefore 

avoided the usual overdimensioning 

of the gear unit and thus achieved 

a much more economical design”, 

emphasizes Niermann. The new industrial 

gear unit consequently allows 

for a significant reduction of the 

drive weight. Thanks to the reduction 

of moving masses and material 

savings in the steel construction 

of the lifting gear trolley, a cost-optimised 

design of crane systems is possible. 

It ensures a long service life and 

low-maintenance operation. 

Another advantage of the new 

gear geometry is a thermal optimisation: 

The enlarged housing surface 

enables improved heat dissipation. 

Thanks to this and thanks to opti- 

U-shaped drive design

the new parallel gear unit XD in five 

sizes with centre distan ces between 

509 and 963 millimetres. Also, in versions 

with three or four gear stages. 

The housing dimensions and centre 

distance are identical for the three-axle 

and four-axle versions. This enables 

customers to standardise and reduce 

variants in the design of their crane 

systems. Thanks to the three-stage 

and four-stage version, it covers a very

time. As for all gear units, the proven 

prin ciple of the robust, one-piece 

UNICASE housing is used. During development, 

the housing was specially 

designed for lifting applications 

and optimised for downward loads. 

In addition, the housing features an 

inspection cover, enabling a visual 

check of internal components without 

having to remove the gear unit. 

It is available in grey cast iron (GJL) or 

nodular cast iron (GJS). 

Another factor that contributes 

to short delivery times and fast availability 

are the various opportunities 

for customers to configure their individually 

required gear units from a 

wide range of standardised options

“For many years, our customers have 

been working successfully with our 

industrial gear units in applications 

in mixers and agitators, belt conveyors,

Seals 

Can elastomers containing PFAS be replaced 

in sealing technology? 

Dipl.-Ing. (FH) Michael Krüger 

PFAS stands for per- and polyfluoroalkyl 

substances. They are organic 

compounds made of carbon chains 

in which the hydrogen atoms are replaced 

by fluorine atoms. “Perfluoro” 

means that the hydrogen is entirely 

replaced, “polyfluoro” means partly. 

The fluorocarbon bond is among the 

strongest, most stable single bonds in 

organic chemis try. PFAS are commonly 

referred to as “forever chemicals” 

since they last for decades. Depending 

on the definition, there are more 

than 10,000 substances in this group. 

Negative properties of PFAS: 

– Extremely high persistence 

(vP – very persistent) 

– Potential for long-distance 

dispersal (through sediments, 

drinking water, air, dust) 

– Accumulation in plants 

– Potential for bioaccumulation 

(accumulation in organisms) 

– Toxicity (some PFAS can cause 

cancer and reduced fertility) 

– Endocrine activity 

(hormonal effects) 

The European Union is currently working 

towards restricting substances in 

the PFAS group. A corresponding restriction 

proposal according to Annex 

XV of the REACH regulation was made 

on 7 February 2023, encompassing 

restrictions in production, bringing to 

market and use. Whether and if so 

to what extent the restrictions will ultimately 

take effect is, however, difficult 

to assess in concrete terms at this 

time. After the scientific evaluation by 

the ECHA, the European Commission 

and the Member States will jointly decide 

on the restrictions that will come 

into force in 2026 at the earliest. 

PFAS are used in numerous industrial 

and consumer products 

thanks to their water-, dirt- and oilrepellent 

properties. They are highly 

stable, especially under extreme conditions 

such as temperature, pressure 

and aggressive media. PFAS are 

very good electrical and thermal insulators 

as well. They are also used 

as coolants and refrigerants, for 

example, in heat pumps or air conditioners. 

And they are good lubricants. 

In addition, the surface-active 

pro perties are used for surfactants. 

Unlike normal surfactants, those with 

perfluorinated carbon chains also repel 

non-polar compounds other than 

oil and grease. 

PFAS are used in sealing 

technolo gy as well, for example, as 

elastomer seals. PFAS compounds 

occur in the following ASTM material 

groups: FKM, FFKM, FEPM, FVMQ 

and others. These sealing materials 

are used in virtually all sectors from 

food and pharmaceutical production 

to the chemical, electrical and semiconductor 

industries to hydrogen 

technology. 

An examination of the use of 

elastomer seals containing PFAS in 

the sealing segment, including FKM 

and FFKM, shows that alternative 

ener gy applications would be prohibited. 

In concrete terms, seals for 

lithium batteries, fuel cells or electric 

cells would be affected here among 

others. Fluori nated elastomers (such 

as FKM and FFKM) are currently used 

for these sealing applications. How-

ever, these PFAS elastomer seals are 

currently not replaceable – or only 

with materials that have significantly 

worse material properties. Substitute 

materials currently do not exist in the 

semiconductor industry either, for 

example, in wafer production. 

In the chemical industry, hightemperature 

applications in particular 

would be affected by a PFAS ban 

along with applications where aggressive 

media come into contact 

with seals – strong acids and bases, 

for example. 

Fig. 1 illustrates the prominent 

position of the fluorinated materials 

FKM and FFKM in ASTM diagram 

D2000 compared to the non-fluorinated 

materials. Both thermally and 

chemically (expressed by the volume 

increase in IRM 903 test oil), this material 

group exhibits properties that 

are not achieved by any other. Seals 

made of these materials therefore 

enjoy an outstanding reputation and 

many everyday applications would 

be unthinkable without them. 

To the extent that alternatives 

for the respective applications may 

actually exist, the user – whether industry 

or also the end customer – 

must be prepared for in part drastically 

shorter maintenance intervals, 

reduced durability and ultimately, 

significantly higher (end user) prices. 

Do alternatives to fluoropolymers 

in sealing technology exist? 

Fundamentally, the answer to the 

question whether fluoropolymers 

(elastomers) containing PFAS can 

be replaced is that it depends on 

the application and the conditions 

of use. 

Crucial reasons for choosing to use 

fluorinated elastomers are: 

– High thermal stability (up to 

+350 °C for FFKM polymers) 

– Very good media and chemical 

resistance (e. g. acids, basis, 

solvents) 

– Combination of low cold flexibility 

with good media resistance 

– Combination of high thermal 

and chemical resistance 

– Low permeation rate and low 

outgassing 

(vacuum and gas applications) 

– High material purity (semiconductor 

and food applications) 

– Longevity in application 

(service life, long maintenance 

intervals) 

– Simplified storage (e. g. reduction 

of the risk of mix-ups) 

Possible (PFAS-free) alternative 

polymers: 

– HNBR: e. g. water-glycol circuits, 

mineral oils, fuels, high strength for 

AED applications 

– Acrylic rubber materials 

(ACM/AEM): e. g. lubricating oils, 

mineral oils with additives 

– EPDM: e. g. polar solvents, hot 

water/steam, bases and acids at 

moderate temperatures, alcohols 

– VMQ/HT-VMQ (silicone/hightemperature 

silicone): 

temperatures up to 300 °C (air) 

– Halogenated butyl rubber (XIIR): 

vacuum applications 

We are going to illustrate the use of 

PFAS-free alternatives using two examples: 

Example 1: Use in a wet cylinder 

liner 

– Material used: FKM with special 

peroxide cross-linked structure 

– Medium: Cooling water with antifreeze 

(glycol) and additives; 

contact with mineral oils is not 

excluded 

– Temperatures: 90 °C up to possibly 

110 °C, in part with steam formation 

(due to thermal conduction) 

– Operating temperature range: 

-25 °C to +200 °C (according to 

specification) 

– Required service life: 

36,000 operating hours 

→ HNBR material with a special structure 

is definitely a possible alternative! 

However, disadvantages have to 

be accepted due to the high operating 

temperature of up to 200 °C 

since HNBR materials are only suitable 

for thermal applications up to 

160 °C. The required service life of up 

to 36,000 operating hours will likely 

be reduced as well. 

Example 2: Application in the semiconductor 

industry 

– Material used: translucent FFKM 

with a special structure 

– Medium: corrosive etching gases 

(e. g. WF 6 

, HCl, HF, SiF 4 

, SF 6 

, O 2 

plasma) 

– Temperatures: possibly up to 

180 °C 

– Ultra-high vacuum up to 10 -6 mbar 

– High purity of the material with low 

outgassing 

→ No alternatives to FFKM are currently 

possible or available!

A PFAS ban would mean that semiconductor 

components such as microchips 

for leading-edge technolo gies 

in AI, medical technology, energy and 

environmental technology – just to 

name a few – are no longer possible. 

In the search for potential alternatives, 

users should be aware why 

fluorinated materials were selected 

for the respective application and 

critically question this choice. The following 

questions can be helpful: 

– Why have fluoropolymers 

(fluororubber materials) been used 

to date? 

– High temperature? 

– Resistance to media (e. g. highly 

concentrated acids and bases)? 

– Combination of media resistance 

and operating temperature? 

– Special applications, 

e. g. high vacuum? 

– Special requirements, 

e. g. high purity? 

– Long service life required? 

– Simplification of warehousing/ 

logistics? 

– Other reasons? 

As illustrated by the above examples, 

viable alternatives do exist – albeit 

in part with significant limitations. In 

other cases – likely for the majority 

of applications by far – there are no 

subs titutes. 

For this latter case, manufacturers 

are striving to replace short-chained 

PFAS substances that are harmful to 

health and used in part during polymerisation 

in the production of fluorinated 

materials with PFAS-free “nonfluoro 

surfactants” – while retaining 

their thermal, mechanical and chemical 

properties. 

Conclusion 

Since the applications of elastomers 

are so varied, the search for a possible 

alternative to fluorinated materials 

should always be conducted in 

cooperation with the manufacturer/ 

supplier! 

Replacing fluorinated elastomers 

is not possible or sensible in most 

cases due to the specific advantages. 

Otherwise, a lower-priced alternative 

would already have been substituted 

for the usually more expensive fluorinated 

materials!

Seals 

Seals for the global market 

Hydraulics, gas and water. Seals are 

found wherever high pressures are 

involved or to prevent the tap at 

home from dripping. The inconspicuous 

parts are installed in a large 

number of devices. The Prädifa 

Technology Division of Parker 

Hannifin Corporation is a leader in 

the development and production of 

sealing solutions. The site in Boom, 

Belgium, specialises in seals made 

from machinable materials such as 

PTFE. The specialists rely on tool solutions 

from Paul Horn GmbH for 

machining. The Supermini and Mini 

systems are mainly used on the machine 

tools. 

“Due to the variety of our different 

seals, we use special tools 90 per 

cent of the time. The materials and 

the different sealing profiles require 

very sharp tools with special cutting 

edge profiles,“ explains Peter Schockaert. 

He is responsible for production 

at Parker Prädifa, together with Johan 

Willems. “The ability to design the 

cutting edge profiles according to our 

wishes and requirements is very important 

to us. That‘s why we‘ve been 

relying on the tools from Tübingen 

for years,“ says Willems.

The tools are often just called blades, 

as they are ground with a very sharp 

wedge angle. Such a tool is used in 

the following application example. 

An axial thread has to be turned on 

a steering shaft seal made from a carbon 

fibre-Teflon material. The thread 

is needed to make the sealing ring 

axially flexible. This allows it to be slid 

over the shaft during subsequent assembly 

and remain securely attached 

after it is screwed on.

The first tests were carried out and 

orders fulfilled with tools that were 

ground in-house. “We grind prototypes 

and small quantities of tools 

ourselves. Then when volumes increase, 

we look for an appropriate 

tool solution,“ says Willems. In this 

case, Horn supplied a Supermini with 

a ground blade for axial machining. 

The thread to be produced has a

and sealing systems, customised 

and application-specific seals and

include companies from the aerospace, 

automotive, pharmaceutical, 

chemical, hydraulics and other industries. 

The company is recognised as 

a leading supplier of poly mer sealing 

solutions made from a variety of sealing 

materials and in a wide range of 

sizes. This diversity also applies to the 

sizes of the seals, which range from a 

diameter of a few millimetres to the 

world record seal having a diameter 

of over four metres.

the thread at a high feed rate. At first 

glance, the machining process looks 

very easy. But the required absence 

of burrs demands a very sharp cutting 

edge. No chips flow during machining. 

The Supermini insert cuts or

Micromachining 

This system is also used for producing 

another plastic seal having a dia meter 

of just under 4 mm. In addition to having 

a face groove, a hole of 1 mm diameter 

must be bored. The sharpness 

of the tools is also very important in 

this application, as the walls are very 

thin and could warp if the cutting pressure 

is too high. After axial grooving 

with a Supermini type 105, another 

Supermini of the same type is used to 

bore the pre-drilled hole to the tightly 

toleranced final dimension.

process does not require any tool 

changes. The tools are permanently 

mounted in line under the spindles. 

During the process, the spindles 

move to each tool in turn until 

all machining operations have been 

completed. 

The Mini system is used alongside 

Supermini tools. “The Mini system 

can be adapted very well to the respective 

machining operations,“ says 

Horn technician Kees van Bers. A tool 

is mounted on the platen for each 

operation. “With the large quantities 

involved, a very short cycle time 

was important to us. The tools allow 

us to carry out external copy turning, 

external grooving, face grooving on 

both sides, boring and parting off,“ 

explains Willems. 

Parker has been working with tool 

solutions from Horn for about 10 years. 

Around 90 per cent of the tools used 

are special solutions designed specifically 

for the respective processes. “We 

are pleased to have Horn as a tool 

partner that fulfils our wishes and requirements 

precisely in terms of cutting-edge 

design,“ says Willems.

Gaskets 

Use of Rubber-Steel-Gaskets in existing 

and future-oriented gas infrastructure 

Dipl. Ing. Robert Steffens 

Permanent, technical and costable 

certainty in planning, design and 

sustainability with any concentrations 

of hydrogen in natural gas up 

to pure hydrogen processes. 

The use of Rubber-Steel-Gaskets made 

of the elastomeric synthetic acrylonitrile 

butadiene rubber (NBR) has been 

common practice for natural gas for 

many years and has been the standard 

for design pressures DP up to 10 

bar. The classic temperature range for 

this is specified as -15 °C to +60 °C. 

The use of rubber gaskets with 

metallic inserts for design pressures 

DP from over 10 bar to 40 bar is permissible 

if proof of creep behaviour, 

blow-out resistance, maximum and 

minimum contact pressure and ageing 

behaviour has been provided in 

accordance with DIN 28090-2/DIN EN 

13555 ( © DIN 30690-1:2019-05). 

The strength of the flange connection 

(DIN EN 1591:2009) for the 

KLINGER KGS GII/NBR Rubber-Steel- 

Gasket can be calculated based on 

the determined sealing coefficients 

(based on DIN EN 13555:2021-04). 

Relevant up-to-date data is always 

available on the internet platform 

www.gasketdata.org.

Specific features of 

Rubber-Steel-Gaskets used in 

hydrogenous processes 

Hydrogen is considered a chemically 

very inert substance under the 

aforementioned operating, pressure 

and temperature conditions. From a 

physical point of view, however, it has 

a very high diffusion pressure due to 

its very small kinetic molecular diameter 

(approx. 2.3 to 2.9 [mA]). This 

means that there is an intensive interaction 

between hydrogen and all 

materials coming into contact with 

hydrogen. 

steel are closed-pore materials that 

do not form a chemical bond with 

each other and only bond to each 

other by interlocking. To significantly 

improve the adhesion of the elastomer, 

the steel insert is first subjected 

to a surface treatment, i. e. 

primed. This causes the adhesion 

force of rubber to the primer – adhesion 

– to be greater than the cohesive 

force of the rubber itself. Even after 

heavy moulding of the steel insert in 

the Rubber-Steel-Gasket, there is no 

shearing of the elastomeric moulded 

body or bubble formation between 

the elastomer and the steel insert.

www.gasketdata.org 

With regard to acrylonitrile butadiene 

rubber (NBR), this means that prevention 

of embrittlement of the elastomer 

due to a high content of acrylonitrile 

(ACN) in the rubber compound 

itself must be assured on an ongoing 

basis, while ensuring that the rubber-elastic 

properties are retained. In 

particular, it is important to keep the 

glass temperature of NBR as low as 

possible in order to enable use at low 

temperatures (as low as -30 °C). Furthermore, 

when manufacturing Rubber-Steel-Gaskets, 

it is important to 

ensure that no cavities can form in 

the elastomeric moulded body itself 

during the manufacturing process. 

Otherwise, there is a risk of rapid gas 

decompression. 

Likewise, the bond between the 

elastomer and the steel insert must 

be particularly strong. Rubber and 

However, the prerequisite for this is 

that the cohesion of the primer and 

the adhesion of it to the steel insert 

are always greater than the cohesion 

of the elastomer itself. 

Thanks to the carefully selected 

materials and precise production under 

very high pressures of up to 300 

bar, the KLINGER KGS GII is a Rubber- 

Steel-Gasket with unique features. 

After testing and evaluation by 

TÜV SÜD, the KLINGER KGS GII Rubber- 

Steel-Gasket was recognised as a particularly 

high-quality gasket. For NBR 

quality, when it comes to the chemical 

and physical resistance of the elastomeric

Ease of use and safe installation 

for sustainable use 

A gasket must essentially close 

two potential leak sources: 

1. Diffusion through the gasket itself 

– 

here it’s very important to 

close any pores or channels in 

the sealing material by means 

of adequate pre-tensioning 

between two flange blades. 

Since the elastomer in question 

– NBR – is a closed-pore 

sealing material and, once 

manufactured into a KLINGER 

KGS GII Rubber-Steel-Gasket, 

a non-porous sealing material, 

diffusion is counteracted to 

the maximum even in the nonpretensioned 

state. 

2. Diffusion between the phase 

limits of the gasket and the 

surfaces of the flange sealing 

strips of a flange connection 

– in this case an effective and 

cavity-free tight fit needs to be 

achieved with adequate pretensioning 

of the gasket.

A special version – the 

KLINGER KGS GII HP Rubber-

Findings 

A variety of tests and test series 

have demonstrated that the

Steel-Gasket delivers durable and 

safe technical tightness with easy 

handling and installation. The 

sealing coefficients determined 

in accordance with DIN EN 13555 

(Helium, He) can be used to calculate 

flange connections in hydrogenous 

and/or hydrogen-containing 

processes.

is possible, e. g. when 

using high-strength screw grades

Compressors/Compressed air/Components 


Kaeser at Hannover Messe 2025 

Sustainable energy savings 

The concept of saving energy and reducing costs through efficient 

compressed air generation is nothing new, but today is more important 

than ever. Heat recovery is a game-changer in this regard, and at 

Hannover Messe, Kaeser Kompressoren will showcase solutions that 

take efficiency to a whole new level. 

Kaeser considers compressed air stations as complex systems in 

which, alongside the compressor, compressed air treatment, exhaust 

heat utilisation, and efficiency monitoring using innovative measuring 

technology all play a crucial role. 

Interactive heat recovery solutions 

The exhaust heat generated by rotary screw compressors, boosters, 

and blowers offers significant yet often overlooked potential for energy 

savings. Kaeser’s innovative heat recovery systems combine efficiency 

with sustainability, making it easy to repurpose this energy for 

space heating, hot water production, or to support industrial processes. 

Designed to meet individual requirements, these systems allow operators 

to select from various temperature levels and water volumes 

to suit their exact needs. Whether installed in new systems from the 

outset or retrofitted to existing ones, Kaeser’s solutions offer unparalleled 

flexibility. 

Using the HMI, Kaeser will present an interactive system that showcases 

the benefits that heat recovery has to offer. A model comprising 

a compressor and a customer system provides a clear, hands-on demonstration 

of its full potential. 

Measuring technology for intelligent control 

To ensure that station control is as efficient, sustainable, and economical 

as possible, modern systems are equipped with state-of-the-art 

measuring technology. These smart systems continuously monitor real-time 

data and automatically optimise station performance based on 

the information gathered. 

Hybrid model for various compressed air applications 

Another highlight is a hybrid model consisting of a miniature compressor 

station combined with 3D-animated compressed air applications. 

This hybrid model demonstrates the versatility and efficiency of Kaeser 

solutions for a wide range of compressed air and blower use case 

scenarios. 

Efficiency and sustainability 

Kaeser takes a holistic approach to compressed air supply, focusing 

not just on energy-efficient generation, but also on exhaust heat recovery 

and intelligent system monitoring. The result is a sustainable, 

resource-efficient compressed air solution that helps businesses reduce 

their carbon footprint while lowering operational costs. Experience 

these innovations first-hand in Hall 12 at Stand B14.

On the other hand, with the new JUMO I/O system for the JUMO vari- 

TRON PLC family, users can expect a family of modules that is 'state of 

the art',” explains Michael Wiener, Global Product Manager PLCs Strategic 

at JUMO. 




makes it possible to store large quantities of gas in vacuum-insulated 

tanks, which resemble thermos flask-like containers. However, storage 

harbours particular risks: If no gas is withdrawn, for example during 

weekends or company holidays, the unavoidable heat input from the 

environment leads to a slow increase in pressure in the tank. As soon 

as the maximum design pressure is reached, the safety valves are activated 

to release the excess pressure. However, this often occurs with 

very loud discharge noises that exceed the immission guide values 

of the Technical Instructions on Noise Abatement (TA Lärm) and can 

cause considerable disturbance to the environment. In the worst-case 

scenario, such an incident is interpreted as a malfunction and emergency 

plans, including the fire brigade, police and rescue services, are 

activated.

The recording app for the JUMO variTRON 500 touch offers an innovative 

recorder function directly on the device for the first time. It enables 

efficient data recording and process visualization directly on site, without 

the need for additional hardware or software. 

This functionality is available on the web for the DIN rail devices 

JUMO variTRON 300 and JUMO variTRON 500, which makes flexible and 

mobile use possible. “JUMO offers its customers a USP because they 

can dispense with a complete device in the form of a classic paperless 

recorder,” emphasizes Niklas Hack, Global Product Manager Data Recording 

& Evaluation/Transmitter at JUMO. 

The recording app that is integrated into the JUMO variTRON family 

is characterized by its high degree of efficiency in data recording and process 

visualization. It enables users to acquire and analyze process-relevant 

data in real time. This makes JUMO PLC systems unique on the market.

Type 2580 overflow valve: The solution for low-noise 

and safe storage 

To avoid such scenarios, the use of the Type 2580 overflow valve has 

proven its worth. This valve is characterised by a proportional control 

characteristic and ensures a steady but quiet pressure reduction in the 

absence of gas extraction by the user. It is set to a pressure below the 

response pressure of the safety valves. This prevents them from being 

triggered and the pressure in the storage tank remains within the permissible 

operating range. Comparable to the control of a vehicle being 

driven at a moderate speed, the use of an overflow valve protects the 

container from overloading. The service life of the system is extended, 

and unnecessary maintenance costs are avoided. 

How the overflow valve works 

The Type 2580 overflow valve regulates the pressure reduction by only 

discharging the amount of gas generated by the heat input. When gas 

is actively extracted, the valve closes automatically to prevent further 

losses. This precision control not only reduces the noise level but also 

ensures maximum efficiency during storage. The valve can be used in 

a temperature range from -200°C to +200°C and therefore offers enormous 

flexibility for a wide variety of operating conditions. It is available 

in various thread sizes from ¼" to ½" and is installed, for example, 

using a connection pipe elbow on the lower connections of a diverter 

ball valve. GOETZE can supply the relevant connection pipe bend on request 

to ensure uncomplicated installation. 

Cryogenic gases - safe, efficient 

and low-noise storage 

Storing technical gases in cryogenic form places high demands on 

safety, efficiency and protection of the environment from loud outflow 

noise. Gases such as argon, oxygen, nitrogen or carbon dioxide are often 

stored in liquefied form, as this enables compact and long-term 

storage. However, this method also poses technical challenges that require 

innovative solutions. 

Challenges in the storage of cryogenic gases 

Technical gases only become liquid at extremely low temperatures. 

For example, one litre of liquid nitrogen at -196°C expands to around 

691m³ of gas at 15°C and an ambient pressure of 1 bar. This property

Advantages of the low-noise optimised bearing 

The advantages of the Type 2580 overflow valve go beyond pure noise 

protection: 

– Increased safety: Continuous depressurisation keeps the system within 

the safe operating range without exceeding critical thresholds. 

– Efficient utilisation: Only as much gas is released as is absolutely necessary 

for depressurisation, gas losses are reduced to a minimum. 

– Longer service life: Relieving the tank of extreme pressure fluctuations 

reduces mechanical stress. The safety valves do not have to 

take on a control task and last longer. 

– Environmental and neighbourhood protection: The low-noise pressure 

control contributes to trouble-free operation and meets the 

requirements of TA Lärm (Technical Instructions on Noise Abatement). 

Conclusion 

The storage of cryogenic gases is an indispensable part of modern industries 

but requires sophisticated solutions to ensure safety and environmental 

standards. Goetze KG Armaturen is therefore advancing 

the state of the art.

Fail-safe supply of pneumatic, electric and data communication 

So that the table rotates, not the staff: 

specially developed rotary unions 

enable 360-degree movement for 

rotary tables with clamping fixtures 

Rotary tables, used for processing complex and heavy components, 

present challenges for plant engineers: as automation increases, so 

does the degree of integration. In addition to the medium required by 

the system, such as compressed air, vacuum or hydraulic oil, the rotary 

tables also need to be supplied with electricity and data interfaces. To 

provide a fail-safe transfer from the stationary to the rotating machine 

elements, complex rotary unions are required, which often need to be 

designed for specific applications due to the many variables involved. 

For new rotary tables with pneumatic clamping fixtures for the production 

of body parts that can continuously rotate 360 degrees, thyssenkrupp 

Automotive Body Solutions turned to KONSTANDIN GmbH. 

The family business based in Karlsbad designed and manufactured 24 

rotary unions, each featuring two compressed air connections with G 

1½" threads, a signal line for Profinet and two additional power conductors. 

Thanks to lifetime lubrication, the rotary unions are completely 

maintenance-free. 

“For our rotary tables with clamping fixtures, we needed specially manufactured 

rotary unions to enable continuous 360-degree freedom of 

movement without damaging the lines,” reports Patrick Hofsommer, 

Head of Assembly Service Body-in-White at thyssenkrupp Automotive 

Body Solutions. While rotary unions for various media such as compressed 

air, vacuum or hydraulic oil are available as standard mo dules, 

the combination of pneumatic transfer with components for power 

and data transmission required in this case had to be specifically designed 

for the application. 




Compressed air, power and data for continuously 

rotating rotary tables 

The newly developed rotary union can rotate 180 degrees in five to 

six seconds, with the motion being intermittent, oscillating or continuous. 

“Generally, we try to use proven standard components for new 

parts as well to keep production costs as low as possible,” explains 

Mathias Kraft, Technical Director at KONSTANDIN. “We followed this 

approach here as well, realising the medium section, as we have done 

many times before, by reworking a standard module.” 

The component is made of stainless steel and aluminium, features 

an interchangeable NBR sealing system and transfers compressed air 

and vacuum between -0.8 and 8 bar over two channels. This ensures 

the functionality of the clamping fixture on the rotary table, as continuous 

motion is required both under pressure and without pressure. The 

necessary power transfer component, however, had to be specially developed 

and designed by the manufacturer for use at thyssenkrupp 

Automotive Body Solutions. For use in harsh industrial environments, 

the power section is dust-tight and protected against splashing water 

in accordance with IP64. Additionally, the rotary union features lifetime 

lubrication, making the on-site replaceable seal the only wear part. 

Fig. 3: KONSTANDIN designed and manufactured a total of 24 rotary feedthroughs 

for thyssenkrupp Automotive Body Solutions, each of which is equipped with two 

compressed air connections with G 1/2'' threads, a signal cable for Profinet and 

two additional power conductors. Source: KONSTANDIN 

Combination of standard modules and custom solutions 

As all technical requirements were discussed and clearly communicated 

in advance, KONSTANDIN was able to manufacture and deliver 

the first eight rotary unions within just three months. Potential problem 

areas, such as the attachment of components to the rotary tables 

at thyssenkrupp Automotive Body Solutions, were identified using 3D 

models and incorporated into the design from the outset. “Our rotary 

unions are typically solutions that are tailored and optimised according 

to customer requirements,” summarises Kraft. “Thanks to our extensive 

portfolio, we can create application-specific products with minimal 

effort using existing rotary union parts.” Patrick Hofsommer also 

expresses great satisfaction with the collaboration with KONSTANDIN.

Heat recovery saves energy and minimises costs 

Heating with compressors 

Compressor operators have a distinct advantage when it comes to reducing 

energy consumption and costs, because the savings are already 

there for the taking. The key to this potential ‘gold mine’ lies in heat recovery 

– up to 96 percent of the energy that is used to produce compressed 

air remains available for reuse as heat.

union is dust-tight and protected against splashing water in accordance with IP64.

100 percent of the drive energy fed to a compressor is converted into 

heat. Air- and water-cooled rotary screw compressors are the bestsuited 

compressor technologies for efficient heat recovery. The greatest 

part of the energy consumed by these compressors, some 76 percent, 

is transferred to the cooling medium. A further 15 percent is 

transferred to the compressed air, and heat losses from the electrical 

motor account for up to 5 percent. Modern, fully-encapsulated rotary 

screw compressors can use targeted cooling to recover this energy. In

The Butterfly Valve 565 by 

GF Piping Systems 

Butterfly valves are traditionally made of metal. Despite this material’s 

robustness, it has some disadvantages as its susceptibility to corrosion 

can not only damage piping systems, but also lead to higher 

maintenance requirements. The thermoplastic Butterfly Valve 565 by 

GF Piping Systems is a versatile and corrosion-free alternative that is 

up to 60 % lighter than similar metal valves. 

100 percent of the electrical energy fed to a compressor is converted into heat. 

With water cooled rotary screw compressors, up to 96 percent of that energy can 

be reused. 

total therefore, 96 percent of the electrical drive energy fed to the compressor 

can be reused for heating purposes. Only about 2 percent of 

the energy is lost as radiant heat and about 2 percent remains as heat 

in the compressed air. 

The most efficient and also the simplest method of heat recovery 

with rotary screw compressors is to directly use the cooling air that has 

been heated by the compressor. Air ducts feed the warmed cooling air 

into nearby store rooms or workshops. If there is no heat demand then 

the surplus heat is simply released to atmosphere via a damper or louvres. 

Thermostatically controlled, motorised dampers control the flow 

of warm air to maintain consistent room temperatures. In addition to 

providing heating or heating support for operating or storage areas, 

the recyclable heat can also be used – for example – to support drying 

processes, to create hot air curtains, or to preheat burner combustion 

air for heating systems (to increase efficiency). The associated investment 

costs are often amortised within a year. 

Reusable compressor heat can also be fed into the hot water heating 

and service water systems. The most cost-effective way of doing so is 

with plate heat exchangers. The heat exchanger is connected to the 

compressor‘s cooling circulation system and transfers energy from the 

warm coolant to the water which is to be heated. Depending on whether 

the hot water is to be used for heating purposes, as showering or 

washing water, or for sensitive production and cleaning processes, 

fail-safe heat exchangers may also be used in conjunction with plate 

heat exchangers. Using these heat exchangers, some 70 to 80 percent 

of the installed compressor power can be used for heating purposes 

without the need for any additional energy consumption. This method 

of heat recovery can also be used with primarily water-cooled rotary 

screw compressors. 

Heat recovery not only significantly enhances compressed air system 

efficiency, but also benefits the environment by preventing unnecessary 

greenhouse gas emissions. The amount of investment required 

is dictated by the onsite installation environment, the application and 

the chosen method of heat recovery. 

The Butterfly Valve 565 Wafer-Style was developed as a durable solution 

for reliable flow control in all water and wastewater applications, including 

swimming pools, potable water treatment and production, hot and 

cold-water plants, as well as refrigeration and HVAC installations. A specially 

cleaned valve for hydrogen electrolysis is also available. 

The 565 covers dimensions from DN 50 to DN 300 and features a 

high temperature and pressure resistance (PN16 at 80°C). In addition, it 

has various approvals such as NSF, DNV, Lloyds Register and KTW-BWGL. 

Housings and valve discs made of materials such as fiber reinforced 

polyamide or PVDF reduce the 565’s weight to 2.7 kg in a DN 

100 configuration with a manual lever. This makes the valve up to 60 % 

lighter than metal alternatives and ensures a fast and easy installation. 

A standard digital interface supports the simple automation and digitalization 

of installations with optional modules such as the Smart Actuator 

or the double sensor with LED position feedback.

The Lug-Style version of the 565 can be installed as an end valve which 

allows piping systems to be disassembled one-sided. Its unique patented 

housing with open sides offers direct access to the stainlesssteel 

plug-in inserts while achieving material and weight savings. The 

removable plug-in inserts also provide additional configurability and 

can easily be recycled at the end of their service life. 

During development, sustainability played an important role. The 

565 is the first industrial Butterfly Valve with an Environmental Pro duct 

Declaration (EPD). Additionally, an independent lifecycle analysis by 

the institute Swiss Climate AG showed that the 565 Wafer-Style emits 

up to 20 % fewer greenhouse gases than metal alternatives, while the 

565 Lug-Style emits up to 26 % fewer greenhouse gases.
