Efficiency and Safety Bonded Together 

Mechanical separating solutions for the chemical industry. 

GEA Westfalia Separator supports the chemical 

industry with high-performance and reliable 

process lines in a broad range of processes. 

Our modern civilization is not conceivable 

without chemicals. Whether synthetics, paints 

or lacquers, oil additives or food additives, 

chemicals rule the world. There is practically 

no area of life that is not impacted by the 

groundbreaking developments of the chemical 

industry. However, the road to the final product 

is long. Complex processes are required to 

recover the substances in the organic, inorganic 

and petrochemical industries. A recurring 

task in these processes is the mechanical 

separation of substances and phases. GEA 

Westfalia Separator has already been 

supporting the chemical industry for decades. 

Our process lines work with separators and 

decanters and also with ceramic membrane 

filtration. The systems we develop with our 

partners produce high quality products in a 

cost-effective, safe, and environmentally 

conscious manner. 

Safety is a priority in the chemical industry. 

Concentrated acids, high pressures and explosive 

substances are part of everyday production. 

Our separators and decanters are capable of 

handling the safety risks involved. For lining 

the solid-wall bowls, GEA Westfalia Separator 

uses corrosion-resistant special materials such 

as Incoloy 825 or titanium palladium. 

Depending on the product, temperature and 

medium, machines of a gastight and explosionproof 

design are in accordance with the new 

ATEX 95 (RL 94/9/EC) directive.

GEA Westfalia Separator 

Current outstanding innovations of the company 

include gastight clarifying and extraction 

decanters with optimized machine geometry 

and high speeds. 

These compact developments combine explosion 

protection with a significant increase 

in performance. A new feature on these 

gastight decanters is the proven Westfalia 

Separator ® varipond ® system. This system 

enables the pond depth in the decanter to 

be adapted optimally while operating, 

producing excellent separating results. The 

decanter always operates ideally, even if there 

are variations in feed concentration.

Nitroaromatic Compounds 

TNT – entirely safe. 

TNT with its almost legendary explosive power 

is probably the best known of all nitroaromatic 

compound substances. However, it is by no means 

the most important. Today, nitration of toluene is 

used primarily in the production of polyurethane. 

Nitration of benzene results in mononitrobenzene 

(MNB), which is the basis of a second key 

input product in the chemical industry, namely 

aniline. Up to 95 percent of the entire global 

production of MNB is used as the primary 

material for isocyanates (MDI), pharmaceuticals, 

rubber chemicals and most dyes. 

Nitroaromatic compounds are obtained in a multistage, 

large-scale process. Mononitration takes 

place in the first reaction tank, and dinitration 

in a second tank. To ensure that the process 

proceeds in a controlled manner, a mixture of 

highly concentrated sulfuric and nitric acids 

is added to the overflow of the corresponding 

stages. After nitration in the reaction tanks, 

the liquid is pumped to a separator so that the 

nitrated aromatic compound can be separated 

from the waste acid. After the reaction mixture of 

the second nitration stage has been separated, the 

dinitro aromatic compounds are pumped to a 

multi-stage washing process. This enables a 

high degree of purity to be achieved for the 

substances. The dinitro aromatic compounds 

are then recovered in a drier in the form of a 

crystalline substance. 

4 


Excellent team right down 

to the smallest seal 

Separators with a solid-wall bowl design, usually 

the TTC series, are normally used to separate the 

nitroaromatic compound from the waste acid 

after the nitration process and also from water 

after washing. The purity of the nitroaromatic 

compounds obtained in this way is excellent. 

Separation takes place in a very small space, 

thereby significantly increasing the safety of 

the installation. Chamber-type separators of the 

type TKC 100 are successfully used in practical 

applications for cleaning the sulfuric acid. 

This increases the operating life of the separator 

in the nitration stages by up to 100 percent. 

Because when sulfuric acid is cleaned this way, 

intervals between the cleaning cycles of the 

solid-wall bowl machines can be extended.

With its aggressive media, the nitration process 

poses extremely stringent demands on the 

separator design in the nitration stages. From 

the bowl to all other components that come 

into contact with the product right through 

to the smallest seal, everything has been 

consistently designed for this process. The 

problem is particularly acute when processing 

nitrated toluene or xylene from the waste acid. 

Special material (Incoloy 825) is used in virtually 

all places where the components come into 

contact with the product. With liquid centripetal 

pumps for both phases, the separators meet the 

requirement for safely discharging both the acid 

and the organic phase under pressure.

Another popular benefit of the TTC separators 

is the location of the discharge drain hole in 

the bottom of the bowl. This prevents the 

operator or service technician from coming 

into contact with the extremely toxic organic 

substances. Throughout the world, virtually 

all well-known manufacturers of nitro- 

aromatic compounds use separators supplied 

by GEA Westfalia Separator. Most of them 

have been doing so for many decades. 

There are specific reasons why GEA 

Westfalia Separator has continued to be 

the main supplier for this application. The 

new TTC generation continues our leadership 

role by meeting the customers’ need for high 

feed capacities, strict installation requirements 

and operator safety.

Peroxide 

The areas of application for peroxide are 

extremely varied. Organic peroxides are 

used as reactants in the chemical industry. 

Hydrogen peroxide is used for the production 

of 1) washing agents used in bleaching paper, 

cellulose, wood and textiles; 2) as crude product 

which will be converted into propylene oxide 

for cleaning waste water and drinking water; 3) 

in the medical industry as a disinfectant; and 

4) for “bleaching” hair. Nowadays, more than 

95 percent of the huge quantities of hydrogen 

peroxide required for these processes are made 

using variations of the anthraquinon process. 

This process comprises the four main stages of 

hydration, oxidation, washing and concentration. 

Within this process, an organic working 

solution circulates through the whole process. 

The working solution is recovered in a one- 

or multi-stage cross-current washing step. 

An aqueous phase is added which extracts 

impurities from the working solution. 

Subsequently, it can be removed from the organic 

phase by centrifugal means. Solid-wall bowl 

separators with a disc stack are used in this step.

In other process applications, an aqueous phase 

is added to extract the impurities from an organic 

peroxide. Similarly, solid-wall bowl type 

separators with a disc stack are used to 

centrifugally separate both phases. 

Maximum safety and separating efficiency 

Peroxides can decompose even in the absence 

of oxygen at low process temperatures. The 

separators are accordingly explosion-protected, 

and the temperatures at the critical points are per- 

manently monitored. The design of the TTC 

separators also provides new methods 

for further improving separating and 

process efficiency. In the majority of the 

peroxide processes described above, the 

light phase makes up the biggest portion of 

the complete flow rate, usually above 90 percent. 

Accordingly, the largest part of the separator’s 

capacity must be used for purifying the light 

phase. This is possible with the TTC series 

type of separators which do not restrict other 

beneficial features, such as discharge of both 

separated phases under pressure.

Xanthane 

Numerous positive characteristics mean that the 

long-chain polysaccharide xanthane is a product 

that can be used universally. In baker’s products, 

xanthane is responsible for pore structure, greater 

volume and an extended shelf life. It is used in 

desserts, chewing gum and ice cream as 

well as in dairy and yogurt products or fruit 

products to improve the texture. Xanthane 

is also frequently found in cosmetic lotions, 

creams, shampoos, liquid soap and toothpaste. 

It is also used in animal feeds where it binds 

water or controls flow properties. It can be 

used to thicken emulsions in the oil 

drilling industry. 

This universal substance is the metabolic product 

of a specific type of bacteria. On an industrial scale, 

the bacteria are bred in large fermenters, and the 

metabolic products produced by the bacteria are 

subsequently harvested. This is where GEA 

Westfalia Separator’s expertise comes into play. 

The actual process of recovery downstream of 

the fermenter takes place primarily in a 2-stage 

process with separators and/or decanters. The 

first stage is for clarification and the second 

stage, namely the washing stage, is used for 

dewatering the xanthane as much as possible. 

Minimum shearing forces, 

maximum margin 

Two factors are particularly important in the 

separation process. These factors are the control 

of shearing forces and explosion protection. 

Shearing forces have a major impact on the 

quality of the long-chain saccharide, and thus 

on the price of the product. 

GEA Westfalia Separator uses a tailor-made 

design to ensure gentle product treatment and 

high throughput. Decanters of the TCA series 

are used for this application. Particular attention 

must be paid to explosion proof protection, 

as the solvents are alcoholic and pose a danger 

of explosion. In this respect, GEA Westfalia 

Separator has been able to implement 

innovations with explosion-protected processes. 

One method of protection involves nitrogen 

blanketing of the machines. Our experience 

ensures maximum safety and maximum 

product quality. GEA Westfalia Separator has 

implemented the requirements specified in the 

ATEX guidelines for decanters and separators.

Petrochemical Additives 

Good lubrication is necessary for a long life; oil 

additives reduce the viscosity of the lubricants 

and thus reduce wear and fuel consumption. 

Clarifying decanters and clarifying self-cleaning 

disc stack separators are used in the production 

of petrochemical additives after a precipitation 

reaction. This reaction is used to remove 

impurities from the carrier liquid, usually an 

organic solvent. The previously dissolved and 

unwanted components of the petrochemical 

additive can then be removed by centrifugal 

force. 

Depending on the pre-concentration, the 

separation process either uses decanters 

or separators or, frequently, uses a 2-stage 

procedure with decanters and separators. 

In general, if the solution has a high solid 

content, a decanter is ideal. These machines 

are more solids oriented than separators. 

If the valuable phase, which is discharged 

after the first separation stage, still contains 

unwanted suspended solids, the user can install 

a polishing separator which removes extremely 

fine particles from the decanter overflow. 

The clarified liquid phase, with the dissolved 

additives, is treated in further processes.

Meeting safety requirements 

With gas-tight, explosion-proof centrifuges 

in accordance with ATEX standards, GEA 

Westfalia Separator guarantees maximum 

safety. Centrifuges are optimized so that 

they are able to meet the specific conditions 

present on every customer’s premises. The 

prime focus is not only on the separating 

efficiency, but also on sophisticated issues such 

as solids transport in the centrifuges. These issues 

are indispensable for continuous operation. 

Centrifugation tests and the experience of 

GEA Westfalia Separator warrants a perfect 

configuration for the installation.

Catalyst Recovery 

Catalysts are chemical substances that speed 

up the rate of a reaction and do not undergo 

any change themselves. They can, therefore, 

be recovered and recycled. This is a valuable 

property as catalysts such as platinum, cobalt 

and manganese are simply too valuable to be 

used just once. In addition, the product obtained 

with the catalyst has to be extremely pure and 

free of heavy metals and any traces of catalyst. 

Plus, simply disposing of the catalyst would have 

environmental implications. 

Centrifugal separation is the most popular 

method for recovering catalysts. They can 

subsequently be recycled back into the process 

improving its cost-effectiveness, quality and 

environmental compatibility. 

Compact challenge 

Very heavy solids often have to be separated 

while recovering the catalyst. However, this is 

only half of the challenge. Some of the solids 

compact so strongly on the wall of the bowl of a 

self-cleaning separator that the discharge gap of 

the system may shift. GEA Westfalia Separator’s 

metering piston mechanism is the right tool for 

handling solids that become compacted. In this 

case, a complete discharge of the bowl ensures 

a high degree of operating reliability. 

If higher solid contents are required, decanters 

of different sizes are used for obtaining 

maximum dewatering and clarification 

efficiency. Chamber-type separators, which are 

able to polish and concentrate the product at 

low feed quantities, are also used. In the newer 

generation of chamber-type centrifuges, the 

liquid is discharged completely from the drain 

holes of the bowl. The valuable catalyst remains 

in the chambers and can thus be discharged 

manually more easily. 

Also, nozzle-type separators especially from the 

TDC series are increasingly used for recovering 

the catalysts. These provide highest clarifying 

results with a defined solid concentration in the 

nozzle discharge. The product contacting parts 

of the entire machine are available in various 

special materials for individual applications, 

different design pressures and explosion 

protection. 

To ensure that every machine operates reliably, 

GEA Westfalia Separator uses its vast experience 

in conjunction with specific pre-trials, to select 

the correct centrifugal system and size.

Dyes, Paints and Inks 

Paints are used in metalworking, in machine 

and equipment engineering and also in the 

automotive, furniture and electrical industries. 

The focus is not only on “visual” quality, but 

also frequently on corrosion protection and 

improving the surface properties. The fact that 

there is hardly any surface that does not require 

a coating demonstrates the major economic 

significance of paints. 

Dyes and paints are a liquid phase containing 

color particles. What appears to be uncomplicated 

at first sight proves to be a genuine challenge 

upon closer inspection. This is because particles 

with precisely the right size must be used to 

achieve the desired color or protective function. 

The solution in this case is centrifugal separating 

technology, using specific classifying decanters 

and separators. 

Put the good ones in the pot 

In classifying decanters and separators, 

the separating conditions are adjusted in 

such a way that only the desired particle 

size is retained in the end product. 

The centrifuge removes all other particles 

efficiently. 

10 


Particles measuring just a few micrometers 

are required in dyes and paints. This means 

that high speeds and large clarifying areas are 

frequently required. Chamber-type centrifuges, 

as well as continually operating self-cleaning 

separators with the Westfalia Separator ® 

hydrostop mechanism, are useful in these 

applications. 

To guarantee maximum quality, the discharge 

system can be controlled with solvent. No 

operating water comes into contact with 

the end product. If organic solvents 

are used in production, it is necessary 

to use explosion protected centrifuges 

incorporating special fittings and materials. 

These machines are equipped with certified 

components and the product chamber is gastight. 

The product chamber, closing chamber 

and gear chamber are blanketed with inert gas 

that reduces the concentration of oxygen in the 

separator to a non-critical level and keeps it 

within safe parameters.

Polyamines and Ethylene Amines 

Polyamines 

Many people absorb this substance during 

their daily food intake. Cheese, beer and yeast 

extracts, for instance, contain large quantities 

of polyamine compounds. So do the human 

intestines. Polyamines are also used industrially. 

Polyamines are produced from chloropropylene 

oxide and amines. They are primarily used 

as hardening agents for epoxy resins from 

which insulating agents, adhesives or coatings 

are produced. 

Ethylene Amines 

Numerous examples for today’s use of ethylene 

amines can be found in various branches of 

industry. The spectrum of products containing 

this substance ranges from textiles to fungicides. 

Cars, too, are dependent on it since ethylene 

amine is used as a fuel additive. Further fields 

of application are rubber processing, corrosion 

protection and bleaching agent production. 

Self-cleaning separators from GEA Westfalia 

Separator are used in the production of these 

products to separate by-products produced in 

the form of solids from the valuable liquid. 

Special features of the separators include: 

A large bandwidth to adjust to a wide 

range of throughput capacities and 

comparatively high solid contents

hydrostop system which enables precise 

partial ejections, recovering more valuable

Sulfuric acid 

Raw 

phosphate 

Phosphoric Acid 

Phosphoric acid is the “source” of many different 

products, from fertilizers to cola drinks. It is 

manufactured on an industrial scale primarily 

by breaking down phosphate rock with sulfuric 

acid in a wet chemical process. Calcium sulfate 

is precipitated and removed by centrifuges. 

However, calcium sulfate is a solid that becomes 

very compact making it one of the most difficult 

products to discharge. At the external periphery 

of the bowl, gypsum simply becomes “concrete.” 

It cannot be reliably discharged with a selfcleaning 

bowl. 

This is the reason why GEA Westfalia 

Separator uses special nozzle-type separators. 

They discharge the solids continuously as a 

Reaction

concentrated suspension while the liquid is 

clarified with highest efficiency and discharged 

under pressure by means of a centripetal 

pump. If the customer wishes to dewater 

the gypsum to a greater DS content to use it 

profitably, they can install a decanter (e. g., 

of the type TCE 535) right after the nozzle 

separator. The same is applicable if there are 

comparable high concentrations of solids in 

the feed. It is frequently the case that decanters 

and separators are used in two different stages. 

GEA Westfalia Separator machines have 

demonstrated their ability to meet all specified 

requirements in the phosphoric acid process. 

Machines for recovering phosphoric acid have 

all product-contacting parts made from special 

materials that resist its corrosive properties. 

This applies especially to the high speed nozzle 

machines (e. g., type TDC 130). If desired, the 

nozzle machine can be supplied with a complete 

recycling loop package unit.

TSC self-cleaning separator 

As a result of decades of experience, GEA 

Westfalia Separator has been able to adapt 

the construction of separators to the specific 

requirements of the chemical industry. Selfcleaning 

separators are used in many applications 

in the chemical industry. They also meet all 

demands of a continuous operating mode. 

The separators are equipped with a disc-type 

bowl and movable sliding piston. The liquid 

is clarified fast and gently in a disc stack, 

whereby the solids are spun out into the solids 

holding space. When the optimum ejection 

point is reached, the movable sliding piston 

is opened hydraulically. The solids are ejected 

instantaneously at operating speed and the 

sliding piston goes back into closed position. 

The clarified liquid is discharged foam-free and 

under pressure by means of a centripetal pump. 

If the liquid must not come in contact with the 

outer air, these separators can be delivered in a 

hydrohermetic (liquid seal) design.

Bowl 

The centrifuge is equipped with a disc-type 

bowl which features nozzles at the periphery 

through which the concentrate is discharged 

continuously. The product flows through the feed 

into the inlet chamber of the bowl, is accelerated 

by fins and passes uniformly through the rising 

channels into the disc stack. Here, clarification 

takes place under the influence of centrifugal 

force. The disc stack consists of a number of 

conical discs placed one above the other. The 

narrow disc interspaces split the liquid into 

thin layers, thus reducing the settling distance 

for the solids particles. The latter settle on the 

underside of the disc above and slide down into 

the concentrate chamber. The clarified liquid is 

conveyed to the bowl center from where it flows 

upwards to the centripetal pump chamber and 

is pressure-discharged.

Inert gas system 

The volume of the clarified liquid can be 

regulated within a certain range by means of 

a throttle (e. g., constant pressure valve). The 

separated solids (concentrate) are continuously 

discharged through nozzles into the concentrate 

catcher. The solids concentration depends on the 

throughput capacity, the feed concentration, the 

nozzle diameter and the bowl speed. The desired 

concentration can be adjusted by exchanging the 

nozzles and regulating the throughput capacity. 

The concentrate flows off under gravity from the 

concentrate catcher.

Drive Concepts for Separators 

Different drive concepts are also available for the separators. Two drive concepts 

are available: flat belt and direct drive. 

Flat belt drive 

This drive concept entails transfer of the motor 

power to the spindle by means of an antistatic 

flat belt. Oil circulation lubrication ensures that 

the bearings are continuously lubricated. 

Compared to the gear drive, which is still used 

in older models, the motor power is transferred 

with up to 10 percent lower power loss. The belt 

itself can be replaced quickly and in a servicefriendly 

manner. 

Direct drive system 

The direct drive is an example of intelligent 

simplification in separating technology. 

Wherever the upper limit for gear loads has 

been reached or belt drives are undesirable, our 

separators with direct drive permit virtually 

loss-free power transmission. This boost in 

performance reduces the costs of energy, wear, 

maintenance and space. 

The required power is transmitted directly to 

the bowl spindle by a 3-phase AC motor with 

frequency converter control via a torsionally 

elastic clutch. The spindle assembly is supported 

by rubber-metal cushions. This makes possible 

low-vibration running at high bowl speeds.

Discharge with 

Westfalia Separator ® hydrostop 

Extremely rapid, precise and flexible. 

With the Westfalia Separator ® hydrostop system, 

GEA Westfalia Separator has developed a 

discharge system that can be adjusted precisely 

and reproducibly to the specific solids 

concentration requirements of the process. 

This patented discharge system enables 

the discharge process to be optimized 

extremely quickly. The Westfalia Separator ® 

hydrostop system reduces the actual 

discharge time to less than ¹⁄₁₀ of a second, 

and permits partial discharge at intervals of 

30 seconds. 

Extremely precise even with extremely 

small volumes 

Older discharge systems were much slower and 

less precise. There were significant fluctuations 

in the volume and thus the concentration of 

the solids. 

16 


It was not possible to exert any influence over the 

process. GEA Westfalia Separator has completely 

solved these problems with the Westfalia 

Separator ® hydrostop system. Volumes as small 

as 1.5 to 2 liters can be discharged repeatedly 

with an error of less than 10 percent. This 

innovative technology is the key to precise and 

rapid discharges and to much higher and better 

quality yields.

Discharge with Metering Piston 

Precisely metered discharge quantities. 

If certain heavy solids have to be separated, 

and if they tend to become very compact when 

subjected to the influence of centrifugal force, 

the metering piston ejection system is extremely 

useful. This mechanism ensures complete 

discharges of the bowl and allows a high level 

of operating reliability. 

Quantity of opening water is easy to set 

A further advantage is that the desired quantity of 

opening water can easily be set with the metering 

piston. The metering device is filled with precisely 

the set quantity of water through the inlet valve; 

compressed air is then forced into the lower 

chamber of the metering device through 

the valve. 

Closing water 

When the opening water valve has been 

operated, the compressed air acts on the piston 

of the metering device and the set quantity of 

water is injected into the opening chamber. This 

arrangement means that it is possible for very 

precise discharge quantities to be achieved. 

The air pressure for the metering device should 

ideally be 4 to 4.5 bar (g). The pressure transformer 

installed in the metering device ensures perfect 

discharge processes, thus overcoming line, valve 

and injection chamber resistances.

The Pair of Centripetal Pumps for 

High Density Differences 

Maximum separating efficiency. 

The centripetal pumps are the real “dream team” 

of the TTC generation. These centripetal pumps 

enable the separating zones to be set precisely 

even in conjunction with very high density 

differences. For example, this is the only way 

to achieve optimum separating efficiency with 

nitroaromatic compounds. In processes where the 

light phase is the valuable phase, the separating 

zone can be positioned towards the periphery of 

the bowl. This way, the light phase is allocated 

a maximum clarifying area. At the same time, 

the twin centripetal pump is able to discharge 

the heavy phase under pressure in an enclosed 

system. This is a major advantage particularly in 

the case of explosive or aggressive media. Unlike 

processes that discharge under gravity, nothing 

can be discharged onto the hood of the separator. 

This avoids the significant cost of making the 

hood corrosion resistant. 

18 


No pump, no costs 

The centripetal pump consists of a cylindrical 

disc equipped with channels. It is installed in the 

centripetal pump chamber of the rotating bowl. 

It is stationary, and its external periphery is 

immersed in the rotating liquid. The liquid 

is discharged towards the center of the pump 

through the channels, and the rotational energy 

of the liquid is converted into pressure. This 

means that an additional pump is not necessary, 

thus achieving savings in investment and 

operating costs.

Bowl Drain Holes 

The solid-wall bowl separators of the 

TTC generation are used wherever it is 

necessary to achieve highest separation 

efficiency of two liquid phases with a very 

low or negligible solids content. Never- 

theless, preventing the possible removal of the 

solids is often not possible. Complete protective 

clothing was previously essential for this work. 

With the TTC generation from GEA Westfalia 

Separator, however, such protective clothing can 

now be left off. This is because these machines 

are the only solid-wall disc-type separators in 

the world whose bowls are completely drained 

by gravity when the machines are shut down. 

Only small quantities of medium (often 

very toxic) remain in the bowl to be cleaned 

manually. Proper washing cycles after stopping 

the bowl can reduce that quantity even further. 

The result: maximum safety even without full 

protective clothing. 

Simple and effective 

To achieve this result, special drain holes are 

designed in such a way that, during operation 

they are “dry” as a result of the centrifugal forces. 

The liquid enters this discharge area only when 

the centrifuge slows down. It then discharges 

completely from the bowl via the drain holes, 

and is collected in downstream tanks via the 

frame drain. Under certain circumstances, 

the drain holes provide the option to carry out 

cleaning-in-place (CIP), draining the product 

first without the bowl having to be opened. 

That offers the client a significant increase of the 

production time and a decrease of the downtime. 

Rotary Brush Strainers and Wear Protection 

Upstream rotary brush strainers and a special coating for components which are 

at risk, protect the separators against clogging and abrasion. 

Excessively large solid particles can clog 

centrifuges, especially in nozzle-type separators. 

This is reliably avoided by installing a rotary 

brush strainer upstream. The product is fed 

into the strainer insert through the inlet, and 

flows through the strainer in the chamber to 

the discharge. The coarse solids are retained 

and scraped off the interior of the strainer by 

the rotating brushes. They fall into the conical 

base, from which they are discharged manually 

from time to time or automatically through the 

solids discharge. 

Special coating against abrasion 

In order to ensure that maximum performances 

are permanently achieved, the nozzle-type 

separators are also equipped with special wear 

protection against abrasion. This solution 

comprises coated wear plates as well as a coating 

on the distributor bottom and the bowl bottom.

Ceramic Membrane Filtration – 

Ultra- and Micro-Fine Clarification 

GEA Westfalia Separator has achieved a new dimension of ultra-fine clarification 

with solutions combining centrifugal separation and filtration technology. 

In addition to centrifugal separation systems, 

GEA Westfalia Separator also has expertise in 

membrane filtration with ceramic elements 

for ultra- and micro-fine clarification of 

particles. Because of this, our company 

is able to significantly expand product 

clarification within a process line. The 

intelligent combination of centrifugation and 

membrane filtration further improves the 

efficiency of the overall installation. 

Individual specifications 

The ceramic membrane installations 

continuously supply a clear filtrate with the 

specified degree of clarification and the desired 

performance. The ceramic membrane forms a 

mechanical barrier with a defined pore size. 

20 


GEA Westfalia Separator provides a wide range 

of ceramic membrane modules in the pore size 

range of ultra- and microfiltration and with 

different membrane materials. The modules 

are mainly standardized, with variable channel 

diameters, element lengths and pore sizes. This 

membrane installation downstream of the 

separator permits extremely fine clarification 

of particles with a diameter of < 1 micrometer.

Decanters 

When clarifier operation is no longer 

feasible due to high proportions of solid 

levels in the suspension, decanters are 

used. The decanter design is based on 

decades of experience in centrifugal 

separation techniques as well as intensive 

research and development by GEA Westfalia 

Separator. Decanters have been developed 

for high clarifying performance and the 

maximum possible degree of solids dewatering. 

Some of the essential conditions include a 

high bowl speed and an enormously high 

scroll torque as well as a control system to 

synchronize differential speed and solids load. 

The product enters the decanter through the 

feed tube and the distributor conveys it into the 

separating chamber where it is accelerated to 

operating speed. The action of centrifugal force 

quickly causes solid particles to sediment on the 

bowl wall. 

The bowl is of a cylindrical/conical shape. In the 

cylindrical section, this shape allows effective 

clarification of the liquid, while in the conical 

section, the solids are effectively dried. 

Solids discharge 

The scroll rotates slightly faster than the bowl 

shell and conveys separated solids continuously 

towards the narrow end of the bowl. Due to the 

conical shape of the bowl, the solids are lifted 

out of the liquid. As the solids pass through 

the “drying zone” which is no longer filled 

with liquid, they are freed from any adhering 

liquid by centrifugal force. The solids are then 

discharged into the collecting chamber of the 

housing through openings in the end of the 

bowl. The liquid flows between the flights of 

the scroll to the other end of the bowl. The slight 

impurities still in the liquid are spun out by 

centrifugal force as the liquid flows through the 

clarifying zone and is pumped by the scroll to 

the solids discharge along with the solids which 

have already been collected in the feed zone. The 

clarified liquid leaves the separation chamber 

under pressure by means of a centripetal pump 

or is discharged downwards under gravity. 

Depending on the decanter type, it may be driven 

by a 3-phase AC motor for controlled torque 

starting or alternatively by a 3-phase AC motor 

with frequency converter. This allows startup 

current and current peaks on start-up to 

be reduced. The power is transferred by belts 

and gears.

Innovative Drive Concepts for Decanters 

Flexible process management with simultaneous maximum availability are essential 

requirements for modern drive concepts. 

The variety of process engineering applications 

in which decanters from GEA Westfalia Separator 

are used requires different drive concepts. This 

is the only way to meet the corresponding 

product requirements in an optimum manner. 

The product line therefore includes drive 

systems with and without the possibility of 

simple regulation of the differential speed. The 

requirements for the machine and process, as 

well as customer wishes, determine what type 

of drive is used. In the case of decanters which 

are used in the chemical industry, flexible and 

precise regulation of the differential speed is 

particularly important. This is the only way to 

achieve extremely high solid concentrations and 

thus high separating efficiency. The 2-gear drive 

and the differential gear drive have therefore 

become established in practice. 

2-motor drive 

The 2-motor drive enables the differential speed 

to be regulated cost-effectively under good 

operating conditions with wide regulating 

ranges. The secondary motor sets the input 

shaft of the gear in motion and generates 

the differential speed as a function of bowl 

speed and gear transmission. The differential 

speed can easily be regulated by changing 

the motor speed. These 2-motor drives are used 

whenever solid volumes fluctuate significantly, 

when solids are conveyed under difficult 

conditions and when stringent requirements 

are applicable with regard to residual 

water content. 

22 


2-gear drive 

The advantage of the GEA Westfalia 

Separator patented 2-gear drive is its facility 

for regulating the scroll drive. The differential 

speed is adapted automatically and extremely 

precisely as a function of the scroll torque – 

and thus as a function of the solids content 

in the bowl. Accordingly, the solids are 

discharged from the bowl with a constant 

concentration and in an extremely dry state. 

These 2-gear drives are used whenever the 

volume of solids is not constant, when the 

solids are difficult to convey and when very high 

requirements are applicable with regard to 

the residual water content of the solids. 

2-motor drive 

2-gear drive

Differential gear drive 

The differential gear drive is recommended 

whenever it is necessary to automatically 

regulate the scroll speed in addition to regulating 

the bowl speed. This can be achieved by means 

of two gears. The secondary motor drives the 

central input shaft and generates the differential 

speed proportionally to its own speed. A second 

input shaft without any speed is connected to the 

housing. This means that the differential speed 

is not dependent on the bowl speed. Differential 

gear drives are used primarily in the lower range 

of the differential speeds. 

Westfalia Separator ® varipond ® – 

reliable mastering phase separation 

The pond depth in the decanter is an important 

parameter with which various performance 

capabilities can be influenced. The Westfalia 

Separator varipond system gives the user 

the opportunity to alter the pond depth 

to adapt to specific conditions during 

ongoing operation. A Westfalia Separator 

varipond disc dips into the clarified liquid phase 

directly in front of the regulating ring. This 

disc forms a hermetic chamber (“Westfalia 

Separator varipond” chamber) together with 

the centripetal pump, to which pressure can be 

applied through a hole in the feed tube. Since 

the liquid level between the Westfalia Separator 

varipond disc and the regulating ring is defined 

by the overflow diameter, overpressure in the 

Westfalia Separator varipond chamber has 

the effect of enlarging the pond depth in the 

decanter bowl in accordance with the principle 

of the communicating tubes. As a result, the 

clarification area is enlarged. 

Differential gear drive 

Westfalia Separator ® varipond ® 

The process operator has a tool that permits 

precise adjustment of the dewatering and 

clarification efficiency. This is indispensable 

for efficient and cost-saving decanter operation, 

particularly in the case of changing feed 

conditions. 

In the case of gas tight decanters, the 

Westfalia Separator varipond system has the 

advantage that it requires no mechanically 

adjustable parts such as rotary leadthroughs. 

It therefore provides a high level of protection 

against discharging harmful gases. 

23 


Centrifuges for High Temperature 

and High Pressure Applications 

GEA Westfalia Separator has found a solution 

to this problem through continuous hightemperature 

clarification with specially 

designed separators. By way of example, nozzle 

separators can only separate particles suspended 

in viscous liquids effectively when their 

viscosity is reduced by increased temperature. 

In the case of some product streams, the 

optimal separating conditions are around 

190 °C. Since many carrier liquids evaporate 

at these temperatures at atmospheric pressure, 

the pressures are around 10 bar. 

24 


The pressure-stressed components including 

hood, solids catcher and protective hood have 

been rated to meet the specific requirements of 

the European Pressure Equipment Directive and 

the American ASME code. The pressure-specific 

segregation of the product space from the drive 

chamber is by means of a double-acting slidering 

packing. Use of suitable materials made 

of Super Duplex and Super Austenite are the 

standard. Suitable elastomers like FKM and 

FFKM are available as gasket materials. 

Every component is subjected to a comprehensive 

quality check to meet the stringent demands in 

chemical sectors. 

Many applications in the chemical industry 

require operating the process at elevated 

temperatures, for example: 

Hot wax clarification 

Production of amines 

Some petrochemical additives 

Food additives 

Fluid gases 

Self-cleaning disk stack separators from GEA 

Westfalia Separator are successfully used in 

such applications at process temperatures up to 

140 °C. This provides high mechanical reliabilty. 

Special care is taken on the choice of materials, 

especially for gaskets. Development of new 

polymer materials now makes it possible to use 

polymers for the bowl main gaskets instead of 

expensive steel-on-steel gaskets.

Wear Protection in Decanters 

and Separators 

Many processes expose decanters and separators 

to extreme material strain. For maximum wear 

protection, GEA Westfalia Separator installs 

armor plating as required in all points of a 

decanter where increased levels of wear can be 

expected, particularly when the machine is used 

for processing very abrasive solids. 

One possible solution is spray cladding, in which 

carbide is welded onto the exposed parts of the 

centrifuge, for example: 

The vane of a decanter scroll 

The distributor of different centrifuge 

types 

The sliding piston of a self-cleaning 

separator 

For protection of a decanter scroll, GEA Westfalia 

Separator also offers the possibility of using tiles 

instead of spray cladding. Tiles are generally 

used for highly abrasive products. 

Another wear point, which is particularly well 

protected by GEA Westfalia Separator, is the point 

at which the solids are discharged through the 

solids discharge ports. 

However, these ports are not protected in the 

same way. Even hard metal welded on to the 

surface in this particular area would erode over 

a relatively short period and would require 

expensive repair work. 

Customer-oriented 

Instead, GEA Westfalia Separator uses special 

sintered hard metal sleeves that provide a much 

higher abrasion resistance. These sleeves 

wear down on one side but can be easily 

turned around. Users have to replace the 

sleeves only when both sides are worn. 

This requires much less maintenance 

compared with welding and results in 

considerably higher availability of the decanter. 

This ensures that wear on the solids discharge 

is manageable. 

25 


Explosion-Protected Centrifuges 

Centrifuges are used in the chemical industry 

for clarifying and separating readily flammable 

liquids. Theoretically, such applications can 

result in critical concentrations of solvent 

vapors and oxygen inside the centrifuge 

that can cause explosions or fires. However, 

the vapors must also be prevented from 

escaping so as not to pose a risk to the health 

of the operators. Both these risks can be 

prevented reliably by using gas-tight centrifuges 

from GEA Westfalia Separator. No sparks, 

no static charges, no hot bearings – the test 

criteria of the strict European ATEX standard. 

In addition, before the start of operation, the 

centrifuge is purged with inert gas and blanketed 

with a slight excess pressure so that no further 

oxygen is able to penetrate. This is because 

fire is not possible without oxygen. When 

processing sensitive liquids, the necessary inert 

gas atmosphere in the separator is automatically 

monitored throughout the entire operation. 

Nothing is able to penetrate this barrier 

An essential design feature of the gas-tight 

separators from GEA Westfalia Separator is 

the gas-tight sealing chamber that separates 

the drive area with the motor from the product 

chamber. This sealing chamber is blanketed 

with inert gas, and the connecting spindle 

is protected with dynamic special seals. The 

sealing chamber reliably prevents the solvent 

from passing from the product chamber to 

the drive area or into the surroundings. This 

makes it impossible for the solvent to dilute 

the oil, which would diminish its lubricating 

efficiency and thus pose a risk to the drive unit. 

26 


The same is also true in reverse: no oil is able to 

penetrate the product chamber and thus have a 

negative impact on the quality of the valuable 

product. 

ATEX 95 (directive 94 / 9 EC) 

A directive for machines operating in hazardous 

surroundings has been in force in Europe since 

July 1, 2003. This affects numerous applications 

in the chemical and pharmaceutical industries, 

particularly where gas-tight machines are used. 

According to the directive, the first step is to carry 

out a risk assessment of the relevant machines to 

identify any present or potential risks. 

The measures are documented and the documentation 

is submitted to an Entitled Body. Specifically, 

this means that GEA Westfalia Separator 

centrifuges are now equipped with fail-safe 

vibration monitoring equipment. This includes 

a bearing temperature measurement as well as 

an inert gas supply unit. All electrical equipment 

must have been awarded an ATEX certificate or a 

manufacturer declaration. This directive is only 

applicable to new machines. A separate directive 

ATEX 137 (directive 1999 / 92 EC) is applicable 

for operators of installations in hazardous areas. 

Operators have also been obliged to carry out risk 

assessments for existing installations. Machines 

and installations must have been assessed by 

no later than January 1, 2006. GEA Westfalia 

Separator offers support for assessing risks and, 

where reasonable, converting these centrifuges 

to the new standards.

GEA Westfalia Separator improves inert 

gas concept 

Requirements with regard to safety and 

reliability are becoming more stringent for 

separators and decanters used in zones with a 

risk of explosion. The existing inert gas concept is 

constantly improved to meet these requirements. 

The latest European standards, as well as GEA 

Westfalia Separator’s practical operating 

experience, are incorporated in the concept. 

As has been the case, the atmosphere in the 

separator is displaced with inert gas before every 

start-up and the excess pressure is maintained 

during operation to meet the requirement for 

minimum inert gas consumption. The fittings 

and measuring devices used have been subjected 

to an extensive test and have also been optimized 

as far as investment costs are concerned. The new 

inert gas supply facility complies not only with 

the familiar directive 94 / 9 EC (ATEX) but also 

with the TA Luft, i. e., product leakages from the 

equipment are reduced to a minimum using 

state-of-the-art technology. 

GEA Westfalia Separator places great emphasis 

on complete and easy-to-understand operator 

documentation as well as a carefully performed 

conformity assessment procedure (CE symbol). 

The company also provides information 

concerning the correct installation of separators 

and decanters in zones that are exposed to the 

risk of explosion. 

27 


Special Materials 

It is important to select the correct material 

for components that come into contact with 

product, such as the bowl, scroll or disc stack. 

Strength, corrosion resistance and hygienic 

specifications are important criteria in this 

respect. In general, the quality of the material 

must increase as the requirements become 

more stringent. The standard material is 

stainless duplex steel, which has high strength 

and excellent corrosion resistance. On the 

other hand, super duplex steel is the preferred 

material for more complex applications. For 

particularly “tough” applications, GEA Westfalia 

Separator uses special alloys such as Incoloy 825, 

Titanium or Hastelloy C4. The load-bearing parts 

(bowl bottom, bowl top and bowl lock ring) can 

also be made of 1.4501 super duplex material. 

A genuine GEA Westfalia Separator speciality is 

the lining of solid wall bowls with Incoloy 825, 

Hastelloy C4 or even titanium palladium. 

In this process, sheets of the appropriate 

special material are incorporated in the 

bowl top and bowl bottom to ensure long 

corrosion protection. The load-bearing bowl parts 

however continue to be made with standard 

materials to permit high bowl speeds. This 

procedure has specific advantages. First, if 

necessary, the lining can be replaced. Second, 

the use of expensive special material is reduced 

to an absolute minimum.

Technology Center for Process Engineering - 

the Reliable Basis for Decision-Making 

Customer-specific tests in Central Process Engineering provide a basis 

for decision-making for all investments. 

No separation is identical with another. In 

many cases, it is necessary to perform a series 

of tests before the correct decision can be 

made for a specific installation. GEA Westfalia 

Separator has set up the Central Process 

Engineering department for this purpose. 

Depending on the specific task involved, test 

series can be run with the customers original 

product in a mobile pilot installation on site or 

in the laboratory at GEA Westfalia Separator. 

The specification of the customer, along with 

operating temperature, throughput capacity, 

clarifying or separating efficiency and other 

factors constitute the information necessary 

to complete a reliable analysis. After every 

test series, the customer receives informative 

documentation in which the technical and 

economic data are detailed. 

Focus on investment protection 

The results from Central Process Engineering 

can be used to precisely identify what machine 

type and what model from GEA Westfalia 

Separator are most suitable for the specific task. 

This procedure avoids poor investments right 

from the very beginning. The customer achieves 

a reliable basis on which he can make the correct 

investment decision.
