About150 visitors from Germany and other countries had an opportunity to get alook behind the scenes at ALLWEILER and hold in-depth discussions withspecialists from the design, production, service, and sales departments.At the beginning of the event, Klaus Stahlmann, CEO and Chairman ofALLWEILER AG, emphasized the importance of “Power Generation” as acentral market segment for his company. ALLWEILER expects this industryto grow over the next few years at a rate that will significantly exceed theaverage. The main reasons for this prognosis are increasing global energyrequirements (exceeding three percent per year), the tripling of natural gas'proportion of power supplies, and the decreasing importance of atomicenergy as a source of power. Demand for energy is expected to increaseparticularly sharply in Asia and South America.It follows, therefore, that power plant operators will need to make significantinvestments in the near future, which will give suppliers of power-plantcomponents and their partners around the world new opportunities toincrease sales. ALLWEILER already has a complete line of products for theseapplications. According to Mr. Stahlmann: “Today we have a market share ofover 20 percent, but over the next few years we want to increase ourpresence significantly in the areas of turbine auxiliary systems and fueldelivery.”The exhibition program included tours of the main plant and the “pumpskid”plant, where ALLWEILER produces ready-to-use components forpower plants. These include primarily skids for moving fuel, lube oil, andpurge water, and the heart of these systems are specific ALLWEILER pumps.Technical presentations by ALLWEILER experts were a major element of thein-house exhibition. The presentations provided a general overview of therequirements of pumps used in power plants and the respective solutionsdeveloped by ALLWEILER. Some presentations addressed how specificpumps fit in to a power plant's central processes, including pumps foru2u3

urner systems and transfer systems as well as pumps used in the productionof biodiesel. Particularly in the latter area, ALLWEILER AG has significantlymore experience and know-how than its international competitors.The processes for producing biodiesel and its intermediate products placespecial demands on pumps and materials. In fact, conventional pumps failquickly under these conditions and are able to stay in service for only ashort time. Yet another presentation explained the special benefits of usingscrew pumps in power plants.The service department explained the best way to bring pumps into service,and how condition-based maintenance and telemetric remote monitoringcan help avoid downtime by detecting the first signs of irregularity.Engineers from the design department gave a live demonstration of moderndevelopment tools like FEM, CFD, and CAE. Their use of these methodsenables them to design flow-optimized housings, spindles, and impellers formore efficient pumps. Visitors could also see with their own eyes howcompact pump sets are designed with a high safety reserve to counteractpressure loads, external forces, and forces coming through the pipes. A reallifeexample of how such advanced tools benefit pump users was demonstratedby a project in which ALLWEILER needed only four weeks to develop aspecial impeller for a cooling-water pump at the request of a major manufacturerof diesel engines. The customer's request was founded upon aneed to increase a motor's power output and therefore also its coolingcapacity by about 20 percent within a short time.ALLWEILER's product line covers especially discharging of fuel from tankertrucks, tank cars, or ships; transloading, circulating, and transferring fuelfrom storage tanks; delivering fuel to oil burners; and injecting fuel into gasturbines. Each of these applications places special demands on the pumpingsystem. ALLWEILER masters a variety of pump technologies, such as two orthree-spindle screw pumps and centrifugal pumps, so planners and operatorsof power plants will always get the most economical and reliablesolution available. Low and predictable lifecycle costs are becoming moreand more important and is another area addressed by ALLWEILER's productstrategy.Throughout the entire event, ALLWEILER presented 23 pumps that arespecifically suited for use in power plants, although they focused onpumping solutions for turbine auxiliary systems and the entire fuel-deliverychain in power plants, large diesel engines, and biodiesel production. Foreach application, the company provides its customers with a specific,precisely adapted product. These include particularly:udry-installed or immersed pumpsucentrifugal pumps and three-spindle screw pumpsutwo-spindle screw pumps especially for large flow ratesugearwheel pumps for low-viscosity liquids under high pressureuprogressing cavity pumps and peristaltic pumps for special applicationsand peripheral systemsSeries NSSVu4u5

ALLWEILER supplies both complete, ready-to-use systems as well as centralcomponents for auxiliary systems surrounding the entire turbo group. Thisincludes pumps that reliably and safely supply lube oil used in the hydrodynamicsleeve bearing, as well as high-pressure pumps for hydrostaticsupport (shaft lifting) when starting or stopping the turbine and turbogenerator. ALLWEILER also provides specific solutions for specific applications.For example, they designed a high-pressure screw pump specificallyto purge burner nozzles and inject high-purity water smoothly and withoutpulsation into gas turbines for the purpose of reducing NOx. Other uses forALLWEILER pumps are: secondary cooling circuits, compressor cleaning,supplying sealing oil to hydrogen-cooled turbo generators, and controllingregulation and safety devices in hydraulic systems.Such an extensive line of pumps employing a variety of pumping technologieshas special benefits for planners and suppliers of power-plant components,because they can get all pumps from a single supplier, which savestime and money during the bidding process. Operators benefit from easyinstallation and start-up as well as from having one contact for bothmaintenance and service. Furthermore, by using ALLWEILER pumps theycan reduce their stock of replacement parts.A new interactive presentation clearly shows how each series and pumptype fits into the respective tasks of moving fuel in power plants, includingdetailed specifications of each product. Complete technical documentationwith dimensions, sizes, power levels, and operational conditions areprovided for every pump. A CD containing this presentation can be obtainedfrom ALLWEILER AG at any time at no charge.About half of the 150 attendees came from outside Germany, includingSouth Africa, Libya, and Russia. Like the in-house exhibition held atALLWEILER's Bottrop location one year ago, this event was a success forboth ALLWEILER and the visitors. More in-house exhibitions for otherindustries are currently in planning for the coming years.The new “ALLUB NSSV” series also made its debut at the exhibition. Thisimmersed centrifugal pump was designed and developed using provencomponents specifically to address the need to supply turbine auxiliarysystems with lube and sealing oil. ALLWEILER plans to offer additionalpumps for this industry.u6u7

Reference Story EOP Biodiesel AGALLWEILER Delivers Pumps Meeting theSpecific Requirements During BiodieselProductionChemical centrifugal pump of the CNB50-200 series, pumped liquid: soy oil.Production of biodiesel and other biogenic fuels (biofuels) has beenexhibiting strong growth for about two years. This trend is driven byincreasing oil prices, the need to reduce greenhouse gases (Kyoto protocol),agricultural-assistance programs, and EU directive 2003/30/EC for addingbiofuels to gasoline and diesel. High oil prices, in particular, have given thisindustry a major boost and are expected to continue for the next severalyears. Pumps are a central component of every biofuel plant. As a result,several pump manufacturers have attempted to employ their standardpumps at these plants as a way to participate in the boom. Many of theseattempts have failed, however, and been very costly for both the plantoperator and its suppliers. With pumps from ALLWEILER operators biodieselplants use with low down times due service and therefore low TotalCost of Ownership.u8These three centrifugal pumps of the NT 125-400 series pump cooling water.Even high-performance pumps like these (maximum flow of 2300 m³/h,maximum delivery head of 145 m, and maximum pump pressure of 16 bar)came straight from the regular product line of ALLWEILER AG.Biofuels generally are difficult to pump. The chemical properties of biodieselare generally much different than conventional diesel and other fossil fuels.This is evidenced by the fact that motor manufacturers, especially in theautomobile industry, are very cautious when approving their products foruse with this fuel. Biofuels and their intermediate products are significantlymore aggressive than petroleum-based oils, and this is the main reason thatmakes them more difficult fluids for pumps (and motors) to handle.Materials that contact the liquid must be extremely durable and have theability to resist corrosion. This begins with the pump housing and continueswith the seals and bearing.Early on, ALLWEILER AG began investigating and resolving the specificrequirements for pumps used in the production of biodiesel. In fact,ALLWEILER delivered pumps to the first Austrian biodiesel plants more than10 years ago. As Germany's oldest pump manufacturer, ALLWEILER has theadvantage of a wide range of products and materials, including especially(magnetically-coupled) centrifugal, rotary lobe, side-channel, progressivecavity, and screw pumps. As a result, this manufacturer is capable ofdelivering complete pump packages for these types of plants. Many plantbuilders and operators find a complete package to be the most attractiveu9I O ENE R GY

Over the past few years,Austrian plant builders have continued to choose these pumps when itcomes time to equip biodiesel refineries, biogas plants, and bioethanolplants. These plants are in operation around the world – from Scotland toAustria.A recent example is the EOP Biodiesel AG plant in the German town ofPritzwalk. Each year this plant produces 30,000 metric tons of biodieselfrom about 100,000 metric tons of rape, putting the plant above 100% of itsoriginal capacity. An expansion begun at the end of 2006 is expected to becomplete by mid-2007 and will increase the plant's production to 130,000metric tons.u11I O ENE R GY

Step-by-step material optimizationThe plant operator started using ALLWEILER pumps immediately with thefirst phase of the expansion. Based on their initial experiences, materialswere optimized one step at a time in order to achieve long service times."In the beginning, sometimes we could only keep a pump in service for afew days. But by working together with the manufacturer we quicklyoptimized the materials and now we achieve normal service times,"according to Sven Schön, a certified engineer and CEO of EOP BiodieselAG. This applied particularly to stators and rotors in the progressive cavitypumps. Temperatures up to 130 °C while drying biodiesel and pH values upto 12 in the various lye solutions make it essential to have very resistantmaterials. For this reason, gray cast pumps used in the beginning werereplaced by stainless steel versions.Centralized replacement parts suppliesThe positive experiences during the initial phase of expansion made thedecision to use the same pumps in the subsequent enlargement and newLeft: Series: CNB 25-160 pumped liquid: sour waterRight: Series: CNB 32-200 pumped liquid: RME - IIIu12Progressive cavity pump of the ANP 6.2 series with quench connectionsand receiving container (not shown).

plant an easy one. Replacement parts played a major role in this. Since allpumps come from a single manufacturer, the plant needs only a smallstorage area for replacement parts, keeping company resources free forother things. Experience has also shown that the manufacturer deliversreplacement parts very quickly. “Although the materials are very durable,rapid and reliable delivery of replacement parts remains an important factor,especially for progressive cavity pumps,” says Mr. Schön. For the samereason it is important to have pumps whose design permits rapid maintenance,like when replacing a mechanical seal. Here as well, EOP has seenthat pumps from ALLWEILER AG have the upper hand. When it came downto details, what really counted was the supplier's experience and the goodcooperation between the supplier and plant builder Cimbria Sket ofMagdeburg, Germany. In addition to the pumps and pipes, adapters andfittings must also be designed to handle the special chemical properties ofbiodiesel products.For all of these reasons, about 90% of the approximately 50 pumps in thenew plant come from ALLWEILER AG. Only in very specialized applicationsdid the operator fall back on other suppliers. In Mr. Schön's view, this wouldhave been necessary much more often with other suppliers since they donot have such a wide product line. In addition, ALLWEILER was able tocover virtually all of the requirements from its normal product line withoutresorting to special solutions or expensive add-on units. As a result, theoperator was able to negotiate very good purchasing and service terms andin very low Total Costs of Owership (TCO).Reference Story Bantleon GmbHPumps in Lubricant ProductionA major business segment at Hermann Bantleon GmbH is the development,production, and sales of lubricants. At its plant in Ulm, Germany, thiscompany starts with high-quality base oils and produces both universal andcustomized lubricants according to its own formulas. Customized productsare often the best way to meet special requirements in cutting and noncuttingproduction processes. They can also make a big difference in termsof efficiency. Hermann Bantleon is the largest shareholder in the lubricantsection of German company AVIA International and sells its products aroundthe world, either through its own network of resellers (China, India, Brazil,Bulgaria, Turkey, and others) or through AVIA trade partners.Bantleon mixes additives to a variety of base oils according to internallydeveloped formulas. Its quality-assurance system ensures the customer aconsistently high level of quality. Accordingly, retained samples are pulledfrom every batch and tested in Bantleon's own laboratory.

Finally, Bantleon values superiordesign. ALLWEILER pumps have very good NPSH values (less than 3 m), sothat long piping and deep tanks ensure adequate reserves for pressurelosses.According to Dieter Schrag, shop and production foreman, "Bantleon andALLWEILER have had a very strong customer-supplier relationship forseveral decades. Our company started ordering ALLWEILER pumps back inthe 1970s and 1980s. Obviously my colleagues made a good choice backthen. Since then we have found no reason to switch suppliers. We havealways been satisfied with the pumps and the support."Bantleon GmbH needs different pump types depending on the specificpumping task. Sometimes the capacity is the critical factor, other times thetype of liquid. When moving non-lubricating or poorly lubricating liquids likeantifreeze, side-channel pumps are used. Centrifugal pumps are ideal forcleanly lubricating liquids. Progressing cavity pumps and peristaltic pumpsare better for contaminated liquids like used oil. Peristaltic pumps areu16u17
