Cover story 

Environmental protection and energy. 

This global issue determines many actions and activities. 

For many countries, protection of the environment has become an overriding social and 

economic concern. For a large part of the population, the role of environmental protection 

is important. It is obvious that more and more people want to make a contribution to 

environmental protection by their personal behavior as consumers. 

Environmental protection is indispensable 

if the basis of human 

life and health is to be preserved. 

Attention is on both 

individual parts of the environment 

such as soil, water, air and 

climate, and on the interactions 

between them. 

Climate protection and 

efficient use of energy. 

Climate protection is one of the 

most important fields of environmental 

protection. Currently, 

above all, the problems of global 

warming and air pollution are 

being discussed. The aim of climate 

protection is to counteract 

unnatural global warming 

and mitigate its consequences. 

In this context, efficient use of 

energy is extremely important. 

Lower energy consumption also 

means lower costs. In this way, 

energy saving also benefits the 

energy saver. 

Energy consumption is often associated 

with the release of carbon 

dioxide (CO 2 

). The most important 

energy sources - coal, 

petroleum and natural gas - con-

sist largely of carbon, which reacts 

with atmospheric oxygen. 

CO 2 

is itself the most important 

anthropogenic (caused by humans) 

greenhouse gas. Greenhouse 

gases in the earth’s atmosphere 

cause the energy 

which the sun radiates to be radiated 

back with a time delay, resulting 

in a rise of the average 

global temperature. 

Since the start of industrialization, 

the CO 2 

content of the atmosphere 

has grown by over 

30%, half of it since 1970. A 

connection between the rise 

of the CO 2 

content and climate 

change, with extreme weather 

events such as storms, floods 

and droughts, is considered to 

be certain. To protect the cli- 

The sustainability concept. 

At the center of the concept of 

sustainability is the insight that 

social responsibility, commercial 

efficiency and protection of 

the natural environment belong 

together. 

In many companies, the concept 

of sustainability has become an 

important subject. Sustainable 

development corresponds 

to the needs of today’s generation, 

without endangering what 

is possible for future generations.

Commercial success. 

Every company which desires 

long-term success needs commercial 

success. Motivated employees 

as well as the smallest 

possible use of resources and 

the environment contribute to a 

long-term increase of company 

success. Sustainability provides 

many benefits for companies. 

Solving ecological problems 

with economical solutions results 

in unique innovations and 

increased productivity and competitiveness. 

For the long-term preservation 

of the quality of our environment 

and our lives, the goals of sustainability 

must be pursued together. 

If our customers, suppliers 

and the politicians are all 

pulling together, successful solutions, 

which can be implemented 

by all stakeholders, will 

be found. 

KRAL innovations make an 

important contribution. 

KRAL is currently making important 

contributions to environmental 

protection for shipping, 

power generation, the burner 

industry and the production of 

polyurethane components. 

For many years, KRAL fuel consumption 

measurement has 

been used where large diesel 

engines do their job. KRAL Volumeter 

help operators to save 

fuel. Almost always, fuel consumption 

is reduced by slightly 

improved driving or operating 

behavior. For example, captains 

of ocean-going ships, fishing 

vessels and work boats have reported 

that they compare the 

KRAL fuel consumption display 

with the engine speed and set 

an optimum speed. In this simple 

way, a fishing vessel reduces 

its consumption from 330 to 300

liters/hour (87 to 79 US gallons/ 

hour), corresponding to a 10% 

saving (see KRAL INSIDE, Special 

Issue for the Marine). 

Creative engineers are developing 

innumerable ways of saving 

fuel. These ideas include auxiliary 

sails for ocean-going ships, special 

paints for the hulls of ships, 

or greatly weight-reduced components. 

KRAL fuel consumption 

measurement measures so precisely 

that developers can demonstrate 

the effectiveness of their 

ideas immediately to their customers. 

Most innovations affect 

the engine directly and are tested 

on the test stand. The KRAL 

system supplies measured values 

immediately, and thus shortens 

test stand runs. 

The most direct way of protecting 

the environment is not to 

consume fuel in the first place. 

Hermetically sealed KRAL pumps 

with magnetic coupling ensure 

that neither liquids nor gas emissions 

reach the environment. The 

engine rooms of ships remain 

clean. Fuel cannot reach the sea. 

In the case of polyurethane production, 

no poisonous isocyanate 

reaches the environment. 

The precision of cylinder lubrication 

in diesel engines determines 

their service life. Until 

now the volume of lube oil has 

not been regulated, but has 

merely been estimated from the 

injector geometry. Our measurements 

have shown that significant 

discrepancies can occur between 

the actual figures and the 

engine manufacturers’ specifications. 

Overlubrication damages 

the pistons and cylinders. Furthermore, 

unused, high-grade 

oil ends up in the used oil tank 

via the overflow oil line. What a 

waste! KRAL enables the specifications 

to be closely and easily 

matched by precisely measuring 

and regulating the volume of 

lube oil. A great deal of money 

can be saved in this way. 

Apart from the effect of saving 

resources, operating and maintenance 

costs are significantly 

reduced with KRAL innovations.

Bombas ITUR was founded 

in Getaria (Spain) in 1920, its 

headquarters later relocating to 

Zarautz. The company has been 

making pumps since it was 

founded, its history giving it one 

of the richest traditions among 

the world’s pump manufacturers. 

With such vast experience 

in the pump sector, significant 

product innovations were always 

possible. Times are changing. 

The fact that ITUR has been in 

business for so long, shows how 

the Basques make use of their 

specialist knowledge of customers’ 

wishes and requirements 

and flexibly implement changes 

in their corporate structure. 

The company’s professional, 

well-developed distribution network 

and technical customer 

support on a partnership basis 

bring ITUR close to its customers. 

This customer proximity is an 

important strategic element and 

has made the company an expert 

in resolving pump projects. 

Customers rate the professional 

and efficient service that is provided 

before, during and after installation 

as particularly helpful. 

All these competences are the 

reason why ITUR is the market 

leader in Spain and is much in 

demand as a contact abroad. 

As the market becomes ever 

more global and open, it is vi-

O.S.P. supports PEMEX in a variety of ways. 

The Mexican economy is subject to continuous and rapid change, to which we consistently 

have to respond with new ideas and services. 

Production hall at O.S.P. 

O.S.P. Service Team at PEMEX. 

The company Obras y Servicios 

Petroleros S.A. de C.V. (O.S.P.) 

was founded by Dr. Miguel Angel 

Monroy Benitez on September, 

26 th 1990 in Comalcalco, Tabasco. 

The aim was to provide 

better opportunities for exploration 

and production, as well 

as selling and marketing to the 

Mexican petroleum market. Petroleum 

is produced and processed 

in our country by PEMEX 

(Petroleos Mexicanos). PEMEX 

is a company that, in the course 

of its 70-year history, has developed 

into one of the most important 

petroleum producers and 

exporters in the world. PEMEX 

is the biggest company in Latin 

America. 

O.S.P. specializes in the installation 

and maintenance of compressors 

and equipment controls, 

centrifugal-, positive-displacement 

and vacuum pumps, 

electric motors, internal-com- 

Top-quality innovative 

solutions. 

The business relationship between 

O.S.P. and KRAL AG 

emerged from the development 

of a solution to save fuel. This 

collaboration led to new energy 

requirement planning for the oil 

pumping equipment. Thanks to 

the KRAL system, installed by 

O.S.P., a precise fuel balance 

that can be documented has 

been implemented. The KRAL 

system measures the amount of 

fuel that is delivered, the amount 

taken from the tank and the fuel 

consumption of each diesel generator. 

PEMEX was surprised 

and impressed by the precision 

of these measurements. 

The KRAL fuel consumption 

measurement system comprises 

eight KRAL flowmeters, the 

BEM 900 electronics unit and the 

BEM 1000 software which was 

developed especially for this apbustion 

engines, valves, and 

machine processing for the petroleum 

industry. PEMEX is our 

company’s most important customer. 

We also offer the same 

standards of quality and service 

to many other businesses and 

authorities. 

The strategic alternative. 

About ten years ago, Mexico experienced 

a turnaround in its history 

when globalization reached 

our shores. Globalization brought 

numerous economic, political 

and social changes to Mexico. 

Many international companies 

arrived, and the business policies 

they brought with them required 

many Mexican businesses 

to adopt a new approach. 

Poor infrastructure, a lack of understanding 

of environmental issues 

and the need to be careful 

with the country’s resources, as 

well as new technologies, were 

typical of the situation. 

O.S.P. took these changes on 

board. Significant demands had 

to be countered with significant 

solutions. This was the only alternative 

in this completely new 

industrial situation. 

A complex task. 

O.S.P. was given the opportunity 

to make PEMEX more 

competitive in oil production. 

Globalization drew many foreign 

companies to Mexico, 

which, like PEMEX, are active 

in the petroleum industry. O.S.P. 

was asked to find a solution 

to increase the efficiency of 

PEMEX’s oil rigs. The aim was 

to avoid unnecessary drilling 

costs. Analyses showed that 

the high consumption of diesel 

fuel was a considerable 

cost factor for the rigs. Diesel 

engines are used to generate 

electricity both in drilling installations 

on land and on offshore 

platforms.

plication by KRAL. The system 

was installed by O.S.P. and tested 

for one year, in cooperation 

with a drilling team. With the exact 

measurements it is now possible 

to identify the optimal performance 

point for each diesel 

generator. The fuel consumption 

previously recorded was 

about 20% higher than the one 

that was now being measured 

accurately. Using these figures 

from the KRAL measurement 

system, PEMEX prepared their 

operating and maintenance 

schedules for their diesel generators. 

The expected and allowable 

fuel consumption is part of 

these schedules. The results are 

in keeping with the corporate culture 

at PEMEX, which involves 

careful and environmentally 

safe handling of the valuable oil. 

On the basis of this positive outcome, 

PEMEX engaged O.S.P. 

to install 20 more KRAL systems 

for their rigs in the south 

of Mexico. 

A friendly relationship. 

The relationship between O.S.P. 

and KRAL has become increasingly 

secure as the challenges 

have become more demanding. 

There is a basis of friendship and 

trust between our companies, 

as well as the common interest 

in working closely together 

to develop made-to-order solutions 

for our customers.

A second pump, just to be sure. 

There are critical applications 

where a second pump is stipulated 

as a safeguard. Providing 

this safeguard by having a 

standby pump always available 

is the basic idea behind double 

stations of KRAL. The standby 

section of the station block is depressurized. 

The corresponding 

pump can be quickly dismantled 

for maintenance. The customer’s

Innovative shipbuilding at the 

Meyer shipyard. 

From wooden boats to specialist ships. 

The Meyer shipyard in Papenburg on the Ems river, Germany, is among the most modern 

shipyards in Europe. Thanks to their flexibility and readiness for innovation, the shipbuilders have 

been able to secure a position close to the front of the highly competitive market for cruise ships. 

The Meyer shipyard in Papenburg: specialist in building modern cruise ships. 

The Meyer shipyard is a company 

with a tradition which began 

in 1795. From the beginning, 

its experts and specialists have 

never stopped building ships of 

the most varied kinds. 

Tradition and progress as 

recipe for success. 

The Meyer shipyard was founded 

for building wooden ships. 

The company is still owned by 

the Meyer family, now in the 

sixth generation. For over 200 

years, the company has been 

constantly developing, and it is 

now at the latest state of the 

art. 

After the years of wooden shipbuilding, 

the company showed 

an early pioneering spirit, which 

has been the basis of the steady 

development of the shipyard. Of 

the about 20 shipyards which existed 

in the small town on the 

Ems in 1920, only the Meyer 

shipyard has survived. Innovation 

and flexibility run through 

the whole history of the company, 

and make its success - it has 

grown continuously against the 

trend in the German shipbuilding 

industry. In 1872, Joseph 

L. Meyer began building steelhulled 

ships driven by steam 

engines, and thus secured the 

company’s future. 

Between the two world wars, 

the shipyard mainly built trawlers, 

pilot vessels, lightships 

and passenger ships for coastal 

travel. In 1960, the company 

began building gas tankers, and 

in 1964, with the MALMÖ, the 

first roll-on-roll-off (RoRo) ferry 

was delivered in Papenburg. 

In the last decades of the 20 th 

century, the Meyer shipyard 

gained an excellent international 

reputation for building car and 

passenger ferries, RoRo and 

passenger ships, gas tankers, 

and above all luxurious cruise 

ships.

the US entertainment company 

Disney placed an order for 

building two cruise ships. 

Up to now, the shipyard has supplied 

23 luxury liners in various 

size classes. Most recently, in

Today, the company has over

jobs in the shipbuilding industry 

and suppliers depend directly on 

the Meyer shipyard. 

Most modern shipyard 

in Europe. 

The Meyer shipyard was the first 

compact shipyard in Europe, and 

is among the most modern today. 

The two roofed dry dock 

sheds, the advanced production 

plant and the concept of short 

paths are what make the shipyard 

successful. That is short 

paths in both the organizational 

sense, for fast decisions, and 

the spatial sense, for distances 

on the shipyard site. In 2008, the 

second dry dock is being extended 

by 120 m, so that larger ships 

can still be built. 

Specialist shipbuilding, above 

all building large passenger and 

cruise ships, is technically and 

logistically very demanding. 

All activity fields are therefore 

equipped with the most modern 

computer technology - from preliminary 

to final design engineering 

and on to production. 

Shipbuilding at the Meyer shipyard 

works on the “Lego principle”. 

This means that small 

parts are produced first, and assembled 

into larger and larger 

units. Steel plates become sections, 

sections become blocks. 

About 70 blocks, weighing up 

to 800 tons each, form a ship. 

As far as possible, the technical 

equipment too is preassembled 

before it is fitted to the ship. 

Thanks to modular construction 

from individual prefabricated 

blocks, the ship can be built in 

the shortest time.

lubricant pumps by KRAL AG are 

fitted. For heavy oil, we increasingly 

use the high quality KRAL 

pumps with magnetic coupling. 

These hermetically sealed 

pumps contribute to increased 

safety on board our ships. The 

fact that fuel can no longer escape 

supports our intention of 

clean ships in a clean environment. 

For older ships, we have 

accepted the attractive offer of 

the KRAL pump upgrade project, 

and replaced pumps with mechanical 

seals with magnetically 

coupled KRAL pumps. 

The Pride of Hawaii was delivered to NCL in 2006. The ship is now working as the Norwegian Jade. 

As far as KRAL is concerned, 

we particularly appreciate the 

helpfulness of the Austrians. 

In one case, in a deadline situation 

which was really tight for 

us, we received large lubricating 

oil pumps for a ferry within just 

3 days. In another case, KRAL 

showed that it was close to its 

customer despite the distance. 

On a request for quick service, 

KRAL engineers responded immediately. 

In a few hours they 

were working here, and they 

solved the problem overnight.

for optimal regulation of the volume of cylinder 

lube oil. 

High operating costs reduce the profits 

of merchant shipping companies. The 

precision of cylinder lubrication in diesel 

engines determines their service life. 

Until now the volume of lube oil has 

merely been estimated from the injector 

geometry. Our measurements have 

shown that significant discrepancies can 

occur between the actual figures and 

the engine manufacturers’ specifications. 

What a waste! In addition overlubrication 

damages the pistons and 

cylinders.

Overlubrication can cause additional 

costs of up to 277.000 USD per ship and 

year. The KRAL cylinder lube oil meter 

allows the volume of lube oil to be regulated 

extremely accurately and helps to 

save expensive lube oil.

Wärtsilä in Switzerland. 

The center for low-speed Wärtsilä two-stroke marine diesel engines 

is located in Switzerland. 

Two-stroke marine diesel engines are used for the propulsion of ocean-going vessels such 

as tankers, bulk carriers and container ships. These marine diesel engines from Wärtsilä are 

developed in Winterthur. 

was put into service in September 

2006. 

A lot of these new research and 

development findings were initially 

tested in the Diesel Technology 

Center in Oberwinterthur. 

At the Diesel Technology Center, 

Wärtsilä Schweiz has stateof-the-art 

research and training 

equipment available. Company 

HQ is located in Winterthur town 

center. At present, over 500 people 

from 40 countries work for 

Wärtsilä in Switzerland. 

The main building of Wärtsilä Schweiz AG (© Wärtsilä). 

Wärtsilä in Switzerland emerged 

from the diesel engine business 

of the Sulzer brothers, Gebrüder 

Sulzer AG, in Winterthur. 

The diesel engine business effectively 

started in 1893 with 

the signing of a cooperation 

agreement between Sulzer and 

Rudolf Diesel over the use of the 

latter’s new engine technology. 

Sulzer manufactured the first 

diesel engines in Winterthur in 

1903. Since 1909, the licensing 

of the technology has played an 

important role in the global sales 

of our engines. 

Marine diesel engines have long 

been one of the most important 

products at Winterthur. Development 

milestones at Winterthur 

include airless fuel injection 

(1930), turbocharging (1946), 

the use of heavy fuel oil (1950), 

loop scavenging (from 1950) and 

conversion to uniflow scavenging 

(1983). Development of elec-

tronically controlled fuel injection 

(common rail) began in 1981. In 

1998, this led to the production 

of the first low-speed, electronically 

controlled common rail RTflex 

engine and in 2001, the first 

RT-flex marine diesel engines 

were commissioned. 

Nowadays, research and development 

focuses particularly on 

reducing the exhaust emissions 

of two-stroke engines. We provide 

efficient solutions for the 

low emission limits of the future. 

By installing highly-efficient 

waste heat recovery systems, 

it is possible to achieve 

fuel savings and reduce emissions 

up to 12%.

KRAL fuel consumption measurement helps safeguard the 

livelihood of Peruvian fishermen. 

Fishing and fish processing are among the most important export industries of Peru. Peru relies 

on its large fleet of small fishing boats, whose owners are suffering vast financial losses because 

of the rising costs of fuel. The call for precise consumption measurement systems is getting ever 

louder. 

For several years, some Peruvian 

fishing companies have been 

testing fuel consumption measurement 

systems for their boats, 

without being able to show any 

viable results or reach any useful 

conclusions. These tests were 

performed with turbine, ultrasonic 

and positive displacement 

measuring systems from various 

manufacturers.

collaboration. 

In 2006, FLUJOMATICA heard 

about KRAL and promptly got in 

touch with KRAL - USA, Inc., to 

obtain extensive advice about 

consumption measurement systems. 

Initially, FLUJOMATICA 

acquired a consumption measurement 

system with PLC control, 

including two OME series 

KRAL flowmeters fitted with 

temperature sensors. The system 

proved its worth when trialed 

with a CAT 3512, the main 

engine of a boat in the TASA 

(Tecnológica de Alimentos S.A.) 

fleet. TASA is Peru’s most important 

fishing company. The 

results achieved persuaded the 

customer to immediately install 

the same system in six more 

boats. The aim is to install a 

KRAL fuel consumption measurement 

system on all the fleet’s 

boats as quickly as possible. On 

the basis of this positive experience 

with KRAL, two more major 

Peruvian fishing companies 

have registered their interest. 

One of these companies has al-

in Lima. 

In November 2007, in Lima, 

Peru, KRAL was represented 

at EXPOPESCA 2007, the international 

exhibition dedicated to 

fishing and fish processing. Our 

agency in Peru, FLUJOMATICA 

S.R.L., presented a KRAL consumption 

measurement system, 

incorporated into a control 

and monitoring system for the 

diesel engines of commercial 

fishing boats. The trade fair 

was a total success and was 

attended by numerous interested 

visitors from Peru, Chile 

and Ecuador. In addition to this, 

FLUJOMATICA has already received 

requests from other 

countries for fuel consumption 

measurement in fishing boats, 

trucks and various other areas 

of application. 

Between sea and sky. 

FLUJOMATICA is also testing 

KRAL fuel consumption measurement 

systems in the locomotives 

of the Peruvian Central 

Railway (Ferrocarril Central 

Andino, FCCA). This is the second-highest 

railway in the world, 

its trains running between sea 

level and 4.818 meters above 

sea level. This difficult terrain 

and the frequent load changes 

require a correspondingly rapid 

response from the system, 

so engineers were tasked with 

combining all these factors in 

a high-precision consumption 

measurement system. 

The future looks optimistic. 

In countries such as Peru, it is 

not just the quality or the price/ 

performance ratio of a product 

that is crucial. In many cases, 

our systems have been rejected 

because they are so precise 

that they demonstrably measure 

and document illicit withdrawal 

of fuel or adverse operating 

practices. 

The KRAL training event in Miami 

(USA) in May 2008 provided 

an excellent opportunity to clarify 

these objections, to learn more 

about KRAL products and to 

look to the future with optimism.

(Petróleos Mexicanos), which 

was founded in 1938. 

Company history. 

On March 18, 1938, President 

Lázaro Cárdenas del Río nationalized 

what had previously 

been the US-American and 

Dutch petroleum groups in Mexico. 

This was based on constitutional 

provisions transferring 

all the country’s resources to 

state ownership, which were 

already in place in 1917. On 

June 7, 1938, PEMEX was established 

as the sole successor 

organization. Several countries 

reacted to this by boycotting 

Mexican petroleum. 

But despite this, Mexico developed 

into one of the largest 

petroleum exporters in the world. 

As Mexico’s largest franchise 

company, PEMEX runs an exhaustive 

network of gas stations. 

Mexico’s most important 

branch of industry. 

PEMEX became one of the 

most competitive companies in 

the world. The company operation 

is modern, transparent, efficient 

and effective. PEMEX feels 

committed to high standards of 

performance and honesty. 

There were great changes to 

the Mexican economy, which 

developed positively. PEMEX is 

now the most important company 

in Mexico. A considerable 

part of the state budget, around 

40%, is financed from oil revenue. 

PEMEX uses its cooperation 

with the industry to influence 

the development of the 

country and ensure a high employment 

rate.

to PEMEX to measure fuel consumption. 

On the oil platforms 

and in land-based production

diesel engines. Although enormous 

quantities of oil are produced 

and processed, PEMEX 

handles the valuable and scarce 

resource very carefully. 

They run the diesel engines at 

their optimum operating point, 

to ensure low fuel consumption. 

They also re-measure the diesel 

fuel that is delivered themselves, 

using KRAL Volumeter. 

KRAL Volumeter also measure 

the extraction flow from the 

storage tanks. All the measurements 

together, that is the engine-related 

fuel consumption 

measurement, the quantity in 

the tank and the quantity extracted 

from the tank, give the 

fuel balance. Nowadays, not a 

drop is wasted. 

What PEMEX really appreciates 

about the KRAL system is the 

centralized display of the fuel 

consumption of all the engines 

of a multi-engine system, as well 

as the opportunity for a customized 

expansion, in accordance 

with PEMEX standards. This is 

because KRAL can integrate individual 

KRAL flowmeters into 

the fuel consumption measurement, 

making it possible to carry 

out complex measuring tasks. 

All the data is stored on the data

KRAL Volumeter in the Corus 

steel works in the Netherlands. 

In every steel works, the converter 

is one of the most important 

systems for evaluating 

the crude steel in the high-quality 

final product. Excess carbon 

is oxidized by feeding oxygen 

to the molten crude iron. 

The crude iron becomes steel. 

This allows vast quantities of 

carbon monoxide and carbon dioxide 

to escape. Gigantic blowers, 

with a capacity of 20.000 m 3 

per minute, ensure that this dangerous 

amount of gas is continually 

extracted. It is absolutely 

imperative for the Corus steelworks 

in IJmuiden in the Netherlands 

that these blowers are reliable, 

as a fault would lead to the 

immediate shutdown of the converters. 

The consequential damages 

from the system downtime 

would reach hundreds of thousands 

of euros. Safety measures 

include monitoring the bearing 

lubrication for the blower. All 

the lubrication systems are fitted 

with flowmeters from KRAL 

to monitor the circulation of the 

lubricant. After intensive testing, 

competent Corus engineers, under 

the leadership of Mr. Fred 

Swinkels, selected KRAL Volumeter 

of the OMG 32 series. 

Because of their high accuracy 

and extremely long service life, 

KRAL Volumeter are currently 

the first choice. The Dutch KRAL 

agency, Intercontrol Meet- en 

Regeltechniek B.V., has since 

delivered dozens of KRAL flowmeters 

to Corus steelworks for 

numerous, demanding applications.

a PUR plant break down. 

Close cooperation 

with KRAL. 

For us, KRAL is both, customer 

and supplier. In Italy, KRAL and 

their agent Decosta, have entrusted 

us with the upkeep 

of their pumps and flowmeters 

in the PUR industry. We 

have also fitted KRAL Volumeter 

series OMH to our modern 

test stand. CAMI chose 

the OMH series because the 

flowmeters are ultra-compact 

and are eminently suitable for 

high pressure and high flow. 

Should a PUR manufacturer 

need a new pump, CAMI is haptive 

and growing business in Italy

To achieve high-precision maintenance, 

CAMI is well-equipped 

with lapping machines, grinding 

machines and chromium-plating 

systems. With this machinery, 

surfaces are returned to 

their original quality and are as 

good as new. 

Final inspection and testing is a 

speciality of CAMI. When maintenance 

is performed on hydraulic 

pumps up to 1.000 cc/rpm and 

450 bar, it is essential, for safety 

reasons, to test the pressure 

after assembly. An acceptance

Should isocyanate be a problem, 

CAMI will use a KRAL 

pump with magnetic coupling. 

The hermetically sealed containment 

can prevents the highly reactive 

isocyanate from coming 

into contact with air. This stops 

the buildup of urea crystals and 

prevents the ultimate blocking of 

the mixing head. A faulty mixing 

head adulterates the formula, 

thereby damaging the PUR end

DB Systemtechnik. 

Global railway technology. 

DB Systemtechnik is Europe’s largest Center of Excellence for railway technology. It is the 

engineering company of DB AG (German Federal Railway), and for many years, its expert 

knowledge has not just been available to the Group, but also to the global railway market. 

BR 120 locomotive of DB Systemtechnik. 

Modern technology on the DB measurement train. 

“The best roof is useless without 

a foundation, without walls 

to support it”, says Hans Peter 

Lang, Head of DB Systemtechnik. 

This characterizes the formative 

role that DB Systemtechnik 

has assumed for the operating 

areas of DB. It is not derived 

from rulebooks or corporate 

guidelines, so it is not “regulated” 

from above, but instead, has 

grown from hard work. Experience 

and understanding of complex 

technology are the foundation 

of DB Systemtechnik. This 

know-how solves the problems 

of day-to-day business in 

terms of vehicles and infrastructure, 

maintenance and operations. 

Neutrality is another factor 

making it inevitable that DB 

Systemtechnik should perform 

a formative function. Independently 

and objectively, it provides 

the optimum balance between 

the interests of transportation 

agencies and the network, making 

sure that there is no risk to 

the economic viability of any of 

the parties involved in the entire 

railway system. 

This independence is particularly 

important in the steadily growing 

outside market business. 

The Test Center and Specialists 

Organization of DB Systemtechnik 

epitomizes this every day. 

Klaus-Albert Bolten, Head of 

the Test Center and Specialists 

Organization at DB Systemtechnik, 

has held the office for three 

years. There have been some 

major changes under his direction. 

The division hit the headlines 

across Railways with the first 

EC certification based on the 

“Freight Wagons TSI”, which 

came into force in 2007 and is 

now helping to make it possible 

to use rail vehicles throughout 

Europe. The Test Center and 

Specialists Organization is much 

in demand as a partner, both at 

home and abroad. Acceptance 

runs for AVE approval in Spain 

and for the new high-speed 

trains in China were as much a 

part of the agenda as the signoff 

runs with the ICE S reference 

vehicle for the high-speed 

track in the Lötschberg Tunnel in 

Switzerland. Vehicle approvals in 

Germany and Europe are also included 

on the DB Systemtechnik 

reference list, as are evaluations 

of individual components or accident 

analyses. This is a successful 

record. These tasks are 

accomplished in 18 test areas, 

spread over all fields of railway 

knowledge. Klaus-Albert Bolten 

explains: “Employees who execute 

the test orders or who prepare 

an expert opinion are under 

the explicit control of the Test 

Center and Specialists Organization 

and are specifically withdrawn 

from day-to-day operations 

of DB Systemtechnik. In 

this way, we safeguard our neutrality 

and independence and are 

far better organized than the corresponding 

outside institutions, 

which have frequently only gath-

ered their experience from just a 

section of the integrated and interconnected 

railway system”. 

The three other business units 

of Vehicle Technology, Maintenance 

Technology and System 

Integration/Infrastructure work 

at monitoring and optimizing the 

railway system and provide engineering 

services for the vehicles. 

The Maintenance Technology 

division not only examines 

every aspect of vehicle maintenance 

and improves and develops 

its systems and programs, 

but also plans the infrastructure 

that is required for this to happen. 

This means that colleagues 

who are not part of DB are also 

on the move and help, for example, 

the Turkish railways, to build 

new factories in Turkey.

The high standards set at DB 

Systemtechnik call for advanced,

technology. The range of services 

we offer also includes checking 

locomotive agreements. Details 

such as fuel consumption 

and power are specified in the 

locomotive agreements of diesel 

locomotives. Keeping to the 

promised fuel consumption is 

particularly important for operators 

in times of steadily increasing 

fuel prices. Fuel consumption 

is one of the measurement 

parameters used to calculate engine 

performance. 

We have obtained several systems 

for measuring fuel consumption 

from KRAL AG. The high degree 

of accuracy demonstrated 

by the KRAL systems is exactly 

what we need. The flowmeters 

do not stay installed in the vehicles, 

but return to our equipment 

store once they have been used 

for measurement. KRAL Volumeter 

are easy to install in an existing 

fuel system. Their electronic 

unit is easily connected to the

Burner technology by ELCO 

improves air quality in Linz. 

In Linz in Austria, stricter requirements 

with regard to air 

quality made it necessary for 

the district heating power station 

in central Linz to be refurbished. 

In 2006, a peak load boiler 

built in 1989 was successfully 

converted from purely heavy 

fuel oil heating to dual-fuel heating 

with natural gas and fuel oil. 

State-of-the-art burner technology 

by ELCO played a leading role 

in this. For the main fuel, natural 

gas, the operator demanded 

the lowest possible emissions. 

Moreover, the burners had to 

be controlled both in combination 

and individually. 

Finally, it had to be possible to 

switch between the main fuel of 

natural gas and the heavy fuel 

oil, without interrupting burner 

operation. Measures taken 

to modify the system included 

replacing the peak load boiler 

heating with four low pollutant 

ELCO Duoblock dual-fuel burners. 

Air was supplied by separate, 

speed-controlled fans. In 

conjunction with the FMS heating 

management system, individual 

operation and a changeover 

of fuel are possible without 

interrupting operation.

The Engine & Machinery Division of Hyundai Heavy Industries Co., Ltd. (HHI-EMD) is the 

world’s leading engine builder. HHI-EMD has enjoyed this reputation since its start in 1978 

with an annual production capacity of 19 million bhp (brake horsepower) covering marine 

and stationary applications. 

Hyundai shipyard in Ulsan, Korea. 

HHI-EMD has won 35% of the 

world’s market share in diesel 

engines. This shows that customers 

all over the world have 

recognized the superior quality 

of Hyundai engines. 

Based on its leading position 

in diesel engine production, 

HHI-EMD has also become the 

forerunner in the diesel power 

generation sector. A great

World class diesel engines. 

Portrait of the German sites of Caterpillar Motoren. 

Nothing is as constant as change. For diesel engine building at the Kiel-Friedrichsort site, 

that means something historically. In the last eight decades, the ownership and company 

name changed frequently. Finally, shortly before the end of the millennium, the decisive 

step took place.

Today, the engines which are 

produced in Kiel and Rostock 

are marketed for shipping under 

the established name “MaK”. 

The engines for power installations 

and the petroleum industry 

carry the trademark “Cat”. Both 

brands have high market acceptance, 

and will therefore continue 

to be used independently.

Aerial view of Caterpillar Motoren, Kiel. 

In early 1997, Caterpillar Inc., 

Peoria, IL, USA, acquired the 

company from Friedrich Krupp 

AG Hoesch-Krupp. Shortly afterwards, 

the name was changed 

to MaK Motoren GmbH & Co. 

KG. Since 1 st August 2000, the 

company has been called Caterpillar 

Motoren GmbH & Co. KG 

for the Kiel site, and Caterpillar 

Motoren Rostock GmbH for the 

Rostock site. The background to 

this was that the parent company 

wanted to emphasize the 

strategic importance of the two 

German sites within the global 

Caterpillar engine business, and 

the implementation of an ambitious 

growth strategy. But it 

was also an unmistakable signal 

of the identification of the parent 

company with these sites. 

Today, Caterpillar Inc. is the 

world’s largest producer of diesel 

and gas engines. In the International 

Caterpillar group, 

the Kiel site is the technology 

center for the larger, medium 

speed diesel engines. The 

factory which was acquired in 

1999 from the insolvency assets 

of Dieselmotorenwerk 

Rostock GmbH (DMR) is an additional 

production site for assembling 

the largest engine series, 

VM 32 C, M 43 C and VM 

43 C. 

High market acceptance. 

For almost 90 years, diesel engines 

have been developed, 

built, supplied and maintained 

in Kiel. For the first 30 years, 

this was under the D symbol of 

Deutsche Werke AG, but from 

which has been introduced to 

the market in a two-year cycle 

since 1992, comprises a power 

range from 1.020 kW to 16.000 

kW with the M 20 C, M 25 C, 

M 32 C and M 43 C series. 

Higher output and economic efficiency, 

improvement of reliability 

and user friendliness, but 

also optimization of environmental 

compatibility, are the 

goals of constant research and 

development work. The international 

success of our engines is 

based on the formula “individual 

+ machine = quality”. Only 

qualified, motivated employees 

and state-of-the-art equipment 

make it possible to meet 

high quality requirements in the 

long run. At Caterpillar Motoren, 

therefore, quality management

Benefits of fuel consumption 

measurement. 

In view of dramatically rising 

fuel prices, measurement of 

fuel consumption is an indispensable 

parameter for operating 

engines efficiently. More 

than ever, low operating costs 

are good sales arguments. As in 

many cases consumption data 

is part of the supply contracts, 

consumption measurement by 

the manufacturer becomes particularly 

important. For this purpose, 

Caterpillar Motoren uses 


by the KRAL AG. In Kiel, these 

devices are used in the test area 

for engine development, and at 

the Rostock site on the acceptance 

test stands. 

Volumeter precision is 

helpful. 

For engine developers, the lowest 

possible fuel consumption 

with the lowest emissions is 

the supreme development goal. 

Here it is important to use reliable 

measured value recording, 

since in this way human inadequacies 

and sources of error are 

excluded and a log of constant 

quality is generated. An objective 

assessment of all components 

which are involved in the 

injection and combustion process 

is only possible in this way. 

For series acceptance, it is decisive 

that the test stands are 

equipped with fuel consumption 

measurement systems 

which ensure that the highest 

requirements for precision and 

reproducibility of the measured 

values are met during the test 

stand acceptance run. Precise 

determination of fuel consumption 

also involves the measured 

values of the brake load, the engine 

speed and the mass flow 

rate of the fuel. Here KRAL AG’s 

differential method of mass determination 

is used.

Ammann fuel engineering – 

cutting-edge technology 

for Ammann asphalt plants. 

All the components in asphalt 

plants operate under the toughest 

conditions, and to withstand 

them, must be robust and reliable 

in construction. The supply 

of fuel to the drier can make an 

important contribution to costefficient 

and ecological operation. 

Oil pumps and all conditioning 

components are put under 

great duress by the drying process 

and by heating the minerals. 

Innovation through 

partnership. 

Five years ago, KRAL and Ammann

strategically interesting, innovative 

idea – compaction of the 

burner hydraulic components. 

The basic idea was to design 

a hydraulic block including all 

the hydraulic components required 

by the burner. Success 

was achieved in the course of 

our cooperation with KRAL. The 

main components of the hydraulic 

block are: 

KRAL pump unit with integrated 

speed regulator. 

KRAL flow measurement system. 

Terminal box with consumption 

indicator. 

Safety valves in the inlet and 

return line of the oil. 

Pressure gages. 

Pressure monitors in the inlet 

and return line of the oil. 

Oil return pass regulator with 

motor operator. 

Oil feed, inlet and return line 

connections. 

KRAL hydraulic block for Ammann. 

Compact design and 

maximum functionality. 

The entire hydraulic block is 

mounted in a frame, to provide 

the requisite protection during 

transportation and maintenance 

work and to guard against harmful 

outside influences. The compact 

pump hydraulic block is preset 

at the factory and installed 

immediately in front of the burner, 

in a position where it is easily 

accessible for maintenance. 

This reduces the amount of installation 

required for the burner, 

as well as the commissioning 

time. At the first light oil 

high-pressure atomizer, maximum 

pump capacity is required 

at minimum burner capacity. At 

maximum burner capacity, only 

half pump capacity is required. 

This is why a frequency converter 

is added to the pump motor. 

This adapts the speed of the 

pump to the required burner capacity. 

That is to say, at maximum 

burner capacity, the pump 

runs at the lowest speed. In this 

way, the oil is no longer heated 

up and the risk of cavitation is 

eliminated. This helps to give the 

pump a longer lifespan and optimizes 

the quality of burner oil atomization 

across the entire control 

range. The complete pump 

hydraulic block has been tested 

and granted certification by the 

German Technical Inspection 

Authority (TÜV). 

Cooperation with KRAL. 

The two Ammann principles of 

using tried and tested engineering 

and designing concepts that 

are geared to meet customers’ 

needs, proved fertile ground for 

the collaboration between Ammann 

and KRAL. The two companies 

brought their expertise 

down to a common denominator 

and created an innovative product 

that reflects its practical development 

and the nature of the 


This exemplary and constructive 

cooperation has resulted in the 

current technological achievement.

250 years of MAN – 

global success with a tradition. 

The leading international manufacturer of diesel engines. 

“Engineering the Future” is the motto of the MAN Group. High-level engineering skill 

and groundbreaking, innovative products – including the first diesel engine – have been 

the hallmark of the company throughout its 250-year history. 

Reliable, innovative, 

dynamic, open. 

The corporate values of the 

MAN Group rest on four solid 

pillars: reliability, innovation, dynamic 

strength and openness. 

Reliability means meeting expectations 

and keeping promises. 

Innovation means accomplishing 

new solutions by fresh, 

creative and competent thinking. 

Dynamic strength means 

recognizing potential and adopting 

a flexible, solution-oriented 

approach. Openness stands for 

close cooperation and the exchange 

of new ideas and information. 

This openness is essential 

for dynamic action.

The MAN Group is one of the 

world’s leading manufacturers of 

capital goods. The companies of 

the MAN Group are MAN Nutzfahrzeuge, 

MAN Diesel, MAN 

Turbo and MAN Ferrostaal. As a 

system provider of commercial 

vehicles, diesel engines, turbomachinery 

and industrial services, 

it delivers the technologies 

for the global growth markets of 

transport, propulsion and energy. 

These are all dynamically evolving 

sectors involved in moving 

vast quantities of goods, people 

and capital. There is a long tradition 

of change at MAN. In the 

two-and-a-half centuries since 

its foundation in 1758 as the St. 

Antony ironworks, the company 

has continually adapted to new 

conditions and made the most 

of its opportunities. As a leading 

international engineering concern, 

the MAN Group is active 

in 120 countries. Currently 43% 

of the 55.000-strong workforce 

is employed outside Germany. 

This figure is steadily increasing 

in the course of internationalization. 

These values are the essential 

factors of MAN’s success in product 

markets, the capital market, 

in obtaining qualified employees 

and for society’s acceptance of 

all their enterprising activities. 

Technology and development. 

MAN’s history is a story of many 

successful amalgamations and 

constant change. But above all, 

it is a contemporary history. The 

coal and steel industry era began 

in 1758, with the founding 

of the first MAN company 

in the Ruhrgebiet, the “St. Antony” 

ironworks. Its competences 

were ore working, smelting 

and processing to make iron 

products. 

The MAN precursor companies 

produced the first German rotary 

printing presses for newspapers

and books, enabling large-scale 

print runs and mass media. In 

1897, Rudolf Diesel developed 

and built the first functioning diesel 

engine in the world at what 

was then Maschinenfabrik Augsburg 

AG. In 1898, this company 

merged with Maschinenbau 

AG Nürnberg to become Vereinigte 

Maschinenfabrik Augsburg 

und Maschinenbaugesellschaft 

Nürnberg A.G. In 1908, the 

company was renamed M.A.N. 

Maschinenfabrik Augsburg- 

Nürnberg AG. 

Right from the start, MAN relied 

on the development and 

power of new technologies. Its 

knowledgeable and daring engineers 

also designed the first 

great steel bridges in Germany, 

the first German steamer on the 

Rhine, the Wuppertal overhead 

railway and key components of 

the European Ariane expendable 

launch vehicles. 

MAN Diesel – powering 

world trade. 

Around 90.000 ships and sophisticated 

logistics are the backbone 

of world trade. Raw materials, 

consumer goods, capital 

goods and semi-finished goods 

have thousands of miles to travel 

before they reach their destination. 

MAN Diesel also benefits 

from continuous growth 

in maritime trade and shipbuilding. 

With about an 80% market 

share, the company is globally at 

the top for two-stroke engines 

and also holds a significant position 

in the four-stroke engine 

market. The propulsion units

Hennecke – a pioneer of 

polyurethane processing using 

high-pressure equipment. 

Developing, designing and manufacturing machinery and 

equipment for polyurethane processing. 

Hennecke is one of the most important manufacturers of polyurethane technology in 

the world and is regarded as the PU equipment manufacturer offering the widest range 

of products. The company has production facilities in Germany, USA, Japan and China. 

Hennecke is represented by its own branch offices in virtually every country. 

Hennecke company premises in Sankt Augustin. 

For more than half a century, 

Hennecke GmbH has been developing 

and manufacturing 

high-quality foaming equipment 

for polyurethane processors 

throughout the world. With numerous 

patents and innovations, 

Hennecke has made a crucial 

contribution to shaping technological 

advance in the PU industry, 

from the first high-pressure 

machine to the current high-tech 

processes with high ecological 

and economic benefit. 

History and development. 

Hennecke GmbH Polyurethane 

Technology was founded in 1945 

as Maschinenfabrik Karl Hennecke. 

Since January 1, 2008, 

the company has been part of 

the Adcuram Group. About 370 

people are employed at their St. 

Augustin site in Birlinghoven, 

Germany. The company has a 

global workforce of around 450. 

In the fifties, Hennecke was the 

first company in the world to 

manufacture PU high-pressure 

metering machines. Since then, 

the company has supplied several 

thousand top-quality machines 

and mixheads for a wide 

variety of polyurethane applications. 

Hennecke stands for the 

development of numerous, innovative 

technologies. These include 

Pentane Process Technology 

(PPT) for eliminating CFCs 

in rigid foam, NovaFlex ® for the 

production of slabstock foam 

with natural carbon dioxide as 

the blowing agent or PUR-CSM 

technology as the generic term 

for diverse spraying processes 

for manufacturing fiber-reinforced 

components for different 

applications. 

Three major industrial customer 

groups consume the lion’s share 

in the world of polyurethane 

(about 70%). They are the automotive 

industry, upholstered furniture 

and mattresses (flexible 

foams) and high and low temperature 

insulating materials (rigid 

foams). Hennecke occupies a 

leading position in the market 

for these areas of application. 

In addition to this, the name of 

Hennecke enjoys a global reputation 

for an exceptionally wide 

range of PU equipment, as well 

as for sophisticated system solutions 

and a high level of expertise 

in consultancy. 

Hennecke slabstock 

production. 

Throughout the world, Hennecke 

is regarded as the specialist and 

market leader in slabstock production. 

A crucial factor here is the 

high rate of return on the equipment 

and the outstanding quality 

of the foams it can produce. 

The production of high-quality 

slabstock foams requires precise 

metering of all components, 

across all ranges of viscosity, 

as well as exactly reproducible 

quantity settings and a vast correcting 

range. 

To a large extent, these criteria 

are met by the integrated highpressure 

metering process, plus 

the injection and mixing principle, 

and by KRAL pumps with 

variable speed control. Computer-monitored 

flow measurement 

with KRAL Volumeter 

creates additional production 

safety, particularly when changing 

the formulation “on the fly”, 

without stopping the system.

A Hennecke MultiFlex system for the 

production of polyurethane slabstock. 

Using KRAL screw pumps. 

KRAL screw pumps are used for 

the slabstock systems of Hennecke 

GmbH. The production 

of flexible foam slabs frequently 

requires large quantities of raw 

materials to be processed. The 

raw materials are usually made 

available in extremely large storage 

tank depots, which operate 

at normal pressure. For further 

processing within the production 

plant, the raw materials have to 

be removed from the tank and 

delivered to the system. 

The metering systems and the 

storage tanks are often a considerable 

distance apart. KRAL 

screw pumps are ideal for transporting 

the raw materials. In 

continual production systems, 

they are used as booster pumps 

for metering the reactive components 

polyol and isocyanate. 

Pumpsets from KRAL meet every 

standard, even with high-viscosity 

raw materials, because 

they are self-priming and charge 

evenly and without pulsation 

over a wide range of quantities. 

In the commonly used magnetic 

coupling version, the lifespan of 

these pumps can be extremely 

long. This applies particularly to 

pumping the isocyanate component, 

which will crystallize on a 

conventional shaft seal if even a 

minimal amount of atmospheric 

humidity is present. 

Pumpsets from KRAL are extremely 

reliable components and 

ensure a high level of productivity 

and equipment availability. 

Using KRAL Volumeter. 

Hennecke GmbH uses KRAL 

flowmeters for their slabstock 

systems. To produce foams with 

different ranges of properties, 

there has to be flexibility when 

metering the numerous components 

in so-called “recipes”. To 

achieve this, the variable speedcontrol 

pumps discharge the individual 

components to the mixer, 

which is continuously rotating 

at high speed (up to 600 kg/min 

total discharge). 

To ensure that all the reactive 

parties are present in the stoichiometrically 

required quantity, 

the pump discharges are constantly 

monitored by KRAL precision 

flowmeters.
