Economic DEvElopmEnt Still heading for growth German pump and compressor manufacturers in 2014 Dipl.-Wirt.-Ing. Christoph Singrün and Dipl.-Volksw. Ulrike Mätje In 2013 the manufacturers of liquid pumps operated slightly above the turnover level of the previous year, while the manufacturers of compressors, compressed air and vacuum technology found their turnover eleven percent above the level of 2012. For 2014, pump manufacturers expect to see 1 % growth, with 2 % growth in turnover for compressors, compressed air and vacuum technology. Liquid pumps: production continues to grow Price-adjusted incoming orders for Pumps + Systems based on turnover 2010 = 100, moving three-month average 160 150 140 130 120 110 100 90 80 70 2006 2007 2008 2009 2010 2011 2012 2013 Foreign Total Domestic In 2011, according to the Federal Statistical Office the production of liquid pumps (without hydro pumps) reached € 4.5 bn, which is nearly the record level of 2008. This value was slightly exceeded in 2012 (+0.5 %) with an overall value of € 4.6 bn. Rotary pump manufacturers took the biggest piece of the cake with more than 40 %, while manufacturers of oscillating or rotating displacement pumps accounted for 10 % each. In the first three quarters of 2013, production generated € 3.5 bn. This is a growth of 2.6 % compared to the same period in the previous year. The volume for the whole year 2013 is estimated at € 4.7 bn. The incoming order statistics for liquid pumps obtained from the VDMA members reflects the economic situation of German pump manufacturers (Fig. 1). Demand throughout 2013 was only slightly below (–1 %) the level in the previous year, with a slight decline in domestic business compared to exports which remained on the same level as in the previous year. In January 2014, capacity utilisation, which is a good indicator for the cushion of orders, was in the “lower” range with 81%. Turnover generated in 2013 was 2 % higher than in the previous year.

Economic DEvElopmEnt than in the same period for the previous year, corresponding to an export volume of € 4.7 bn. It looks as if a volume of € 5.1 bn will be achieved for the whole year 2013. And so Germany remains unchallenged export world champion. In the world trade volume of around € 31 bn (2012), German manufacturers account for about 16 % (Fig. 2), well ahead of the USA and China (with 12 % each). Europe remains the key sales market for German liquid pumps, accounting for altogether around 58 % of exports. Asia accounts for a further quarter of sales, with 9 % of exports going to North America. German pump exports to North America saw a clear increase in 2012. Demand for German pumps grew particularly in the USA with 11.7 %. Mexico nearly doubled its imports, but this accounts for only 8% in the total volume of exports to the NAFTA. There has been a clear decline in growth in Asia. Increases were only registered in deliveries to Singapore and Thailand. Exports to Africa declined for the Pumps + Systems 2012 Germany’s main export markets, percentage shares Total: 4.8 billion Euro (without hydro pumps) China 8.7 % USA 8.0 % Czech Republic 7.3 % Others 45,0 % France 7.0 % Russia 6.4 % Great Britain 4.0 % Italy 3.9 % Netherlands 3.6 % Austria 3.2 % Source: Federal Department for Statistics / VDMA Poland 2.8 % Fig. 3 third year in succession. In 2012, the main customer countries South Africa and Egypt imported 5 % respectively 16 % fewer pumps from Germany than in 2011.

Blue CompetenCe Blue Competence – VDMA’s sustainability initiative picks up pace Dipl.-Volksw. Ulrike Mätje Shorter standstill times due to high-strength materials in pump cogwheels and plain bearings, or recovering helium from leak testing processes – these are just two practical examples of implemented sustainability. “Do good and talk about it!” – that’s the motto of the VDMA’s Blue Competence sustainability initiative. It positions the engineering sector as the enablers in the economy – for both sustainable production and also sustainable products. Meanwhile around 400 companies have joined in with the initiative which was launched in October 2011, with participation increasing all the time. Selected Blue Competence Best Practices Click on the logos and learn more about selected success stories for pumps + systems as well as compressors, compressed air and vacuum technology (articles only in German) Together we’re strong Companies from 38 product areas together with their associations and organisations are involved in Blue Competence, where they undertake to fulfil verifiable sustainable criteria.

Blue CompetenCe Website with double benefit A comprehensive overview of the campaign can be found on the website www.bluecompetence. net. A search function has now been added to give the website a useful value in the long-term. There is a standard layout for success stories which can be used both as .pdf on the website and also by companies as flyers for trade-fairs etc. Companies involved in Blue Competence that submit their success stories in future will therefore see a double benefit: the success story will be presented in the framework of the Blue Competence website and can also be used for the company’s own PR work. Implemented sustainability One important criterion for submitting success stories consisting in filling the fact box (blue box on the back of the flyer) with figures and verifiable facts. Background: the success stories submitted by Blue Competence partners act as credible, verifiable evidence of their sustainability according to the Blue Competence usage agreement. External stakeholders such as the political sector, customers and the general public demand measurability and verifiability. The facts and figures help to take this into account.

VDMA BuilDing SySteMS The building sector is one of the key sectors of the economy. The construction of buildings accounts for a good € 180 bn each year. The VDMA member companies whose products are also supplied for building systems generate a production volume of around € 15 bn p.a. The way buildings are equipped with systems and technology makes a vital contribution to the conditions in which people live and work in developed societies. At the same time, the building sector is responsible for around 40 % of primary energy consumption. The VDMA Building Systems Forum covers the following areas: • Valves • Lifts and escalators • Automation + management for house + building • Decentral energy supply • Maintenance • Refrigeration • Air conditioning and ventilation • Pumps and systems • Security systems Pumps and Compressors for the World Market with Compressed Air and Vacuum Technology 2014

RESEARCH German pump and compressor manufacturers enjoy a high reputation worldwide thanks to their capabilities and problem solving quality. Introducing the Pump Research Fund (FFP) and the Vacuum Technology Research Fund (FFVak) Harald Frank and Jürgen Eisenreich For many years, the VDMA has been successfully involved in organising and handling cooperative research projects. In the framework of pre-competition industrial joint research, it works together with the orschungskuratorium F M aschinenbau e. V. (FKM) (Engineering Research Board) and the research associations of the various branches to offer two efficient, beneficial cooperation platforms: the Pump Research Fund (FFP) and the Vacuum Technology Research Fund (FFVak). Pumps and Compressors for the World Market with Compressed Air and Vacuum Technology 2014

17
RESEARCH The Pump Research Fund It was already back in 1973 that the VDMA association Pumps + Systems set up the Pump Research Fund (FFP) to conduct joint research in pump construction. The FFP is part of the VDMA’s research network. Joint research projects are mainly implemented and financed with public sector funds. The European Commission estimates that throughout the EU, pumps and pump systems consume around 30% of the energy provided by electric drives (SAVE study, 2000). Within the EU, electric drives in turn are responsible for approx. 30% of all electrically generated energy, so that pumps and pump systems consume about 10% of electrically generated energy or 280 TWh p.a. – in Europe alone. Pumps and pump systems therefore count among the major energy consumers. Pump manufacturers have to invest in research and innovation, among others in view of the statutory demands and minimum efficiency requirements made of pumps and pump systems - take for example the Energy using Products (EuP) / Energy related Products (ErP) Directive. Although the products of Germany’s pump industry already embody the highest technological standard today, German manufacturers as technology leaders see their responsibility for pursuing specific research activities to save resources in both the production and operation of the pumps, thus protecting the environment and offering sustainable concepts.

EnErgy EfficiEncy Energy efficiency: the VDMA as reliable partner Friedrich Klütsch Following a brief period when energy efficiency temporarily receded into the background with attention focussing on alternative energy sources with their subsequent problems (grid expansion, storage issues), it is now currently enjoying a renaissance. After all, energy efficiency is the “energy form” where every individual and every branch of industry including engineering can assume responsibility for making a major ontribution. c The VDMA associations Pumps + Systems as well as Compressors, Compressed Air and Vacuum Technology have been supporting their members in this respect long before the efficiency activities of the European Union. By launching the initiative “Druckluft ffizient” in 2001 the compressed air industry was one of e the first industries in the mechanical engineering, that introduced the topic of energy effiency to customer circles.

Submersible pump motor units are used in all parts of the world in order to drain, for example, mine pits for coal, rare earth and gold. Photo: Andritz Ritz New submersible pump motors for highest requirements Ludger Gottkehaskamp, Johann Neiszer and Georg Cichon For the submersible region of mines, water wells and subsea applications pump motor units of 12 inch size with significant improvements have been developed. On the pump side, the efficiency levels could be raised from 74 to 80 % and on the motor side from 88 to 93 %. With the pump, the delivery head per stage was almost doubled. In the motor, a performance improvement of up to 30 % was achieved with the same size. These performance increases led to improvements of the overall efficiency levels from 65 to 74 %, which directly affects significant lower energy consumption and thus a better efficiency.

pumps & systems Submersible pump motor units, which consist of submersible centrifugal pumps and submersible asynchronous motors, are used in many areas for the conveyance of waters of different water quality. The performances range from a few kilowatts to some megawatts, the flow from a few to some thousands of cubic meters per hour and the delivery heads to over 1,000 m. For many years, such submersible units are used in all parts of the world in order to drain, for example, mine pits for coal, rare earth and gold. In arid zones, these units are used for pumping water from wells for the potable water supply and field irrigation. This article describes the results from a development project, which were achieved with a new pumping and motor series. Parameter for pump and motor P1 = Net power P2 = Shaft power g = Gravity acceleration ρ = Density H = Head Q = Flow ƞM = Motor efficiency ƞP = Pump efficiency ƞtot = Total efficiency P2 = ƞM = ρ*g*H*Q ƞP P2 P1 ρ*g*H*Q P1 ƞtot = ƞP * ƞM = Fig. 1: Parameter for pump and motor, energy process within the aggregate Requirements of submersible pump motor units Customised requirements and technical innovations are considered in the development, sizing and manufacturing of submersible pump motor units. Depending upon operating condition of the units, certain requirements for the pump and motor must be fulfilled apart from high efficiencies, different material adjustments, simple assembly and disassembly, which were listed in the following. Requirements for submersible pumps: • Steady rising pump curve of flow and head • Maximum hydraulic head per stage • Minimal material use per stage • Usable at different pump speeds Requirements for submersible motors: • Applicable in connection with a frequency converter • High specific power per motor volume • Internal cooling in connection with heat exchanger and suction jacket • Water or glycol water mixture as filling medium (Q) at a given delivery head (H) analogous to the pump curve . The ratio delivery head multiplied with flow, gravity and density to shaft power is expressed through ƞP (pump). The power from the electrical net (P1) is fed into the motor. This power is largely transferred into rotation (P2 = shaft power) and to a very small proportion in losses (e. g. heat). The ratio of power used (P2) to net power (P1) is illustrated by the motor efficiency ƞM (Motor) (Equ. 2). The value crucial for the operator is shown by the overall efficiency level ƞ total (Equ. 3) of the unit. This number finally reflects which energy is used or remains unused.

InnovatIons & trends Multiphase pumps for energy-efficient Dr. Jürgen Holdhof Multiphase pumps are unique products with outstanding features compared to conventional centrifugal pumps. The approach consists of using the pumps not only for transport of liquids but also for partial gas supply and as dynamic mixer for gas enrichment. Therefore this novel pump conception barely has something in common with a standard pump. Even the mode of operation does no longer comply with the common doctrine: the multiphase pumps are slightly throttled at the inlet side, in order to get automatically sucked in gas contents. Pumps and Compressors for the World Market with Compressed Air and Vacuum Technology 2014

23
pumps & systems water and wastewater treatment A large market segment is the water and waste water treatment by means of dissolved air flotation where the multiphase pumps provide the task of air saturation without the use of compressed air. With standard centrifugal pumps this inevitably would result in cavitation. Multiphase pumps are suitable for many processes. Gassing liquids that also need to be handled by pumps occur in many applications. A large market segment is the water and waste water treatment by means of dissolved air flotation where the multiphase pumps provide the task of air saturation without the use of compressed air.

InnovatIons & trends Piston diaphragm pumps to remove Dipl.-Ing. Friedrich Wiechmann Rising raw material prices mean that ore and coalmines even in remote and little developed or exploited regions of the world have become profitable. The local infrastructure in those regions is usually not comparable with the infrastructure in Europe. Road and rail onnections are usually absent across c large parts of the areas in question, which is why pipelines are built alongside rivers, through deserts, mountains, and jungles. The line does not follow the g eologically most favorable route but is instead the shortest route to the next harbor or the next processor. This is why it might be favorable to transport the accumulated ore and coal sludge by means of pump units. Pumps and Compressors for the World Market with Compressed Air and Vacuum Technology 2014

InnovatIons & trends Metering technology for biogases and biofuels Rainer Sonnenfroh and Walter Richter Biogas, as a CO2-neutral energy source, is a future market. The additives used for odorizing or to increase combustion values, however, are just as hazardous as the products that are conveyed during the manufacture of synthetic fuels from biomass. So the pumps used for this purpose must be hermetically tight even under critical process conditions like extreme temperatures and high pressure. Diaphragm metering pumps – especially if the diaphragm consists of multiple layers – have the best characteristics for this purpose, since they can completely eliminate the need for dynamic seals. The pumps work thermodynamically optimally and can be used over a very wide range of temperatures. Pumps and Compressors for the World Market with Compressed Air and Vacuum Technology 2014

INNOVATIONS & TRENDS Intelligent design for hygienic pumps Rainer Gozzer EHEDG, QHD and FDA make exact demands on machines for the food and pharmaceutical area. These not only involve production facilities themselves, but also all conveying systems which come into contact with the medium. So as to make the progressing cavity pump fit for this area of application and to bring it into compliance with the strict regulations, numerous changes have been made to the proven design, including materials, construction and seals. The hygienic pumps which emerged from this process have now come into use not only purely for transporting materials, but also to take on emptying and dosing tasks.

Energy generation from geothermal sources relies on generator-loaded, multi stage – in this case two stages – integrally geared expansion turbines (Shown here: Geothermal power plant outside the town of Pamukören, Turkey). Photo: Atlas Copco Radial turbines for energy generation from geothermal resources or waste heat recovery Prof. Dr. Pall Valdimarsson and Dipl.-Ing. Markus Sauerborn The implementation of sustainable solutions is becoming a major focus of mechanical engineering. This emerging trend is also reflected in the growing number of geothermal power plants. From a market perspective, we are seeing a major push towards geothermal resources with low enthalpy. The key t echnology for unlocking these power sources is the Organic Ranking Cycle (ORC), a process in which turboexpanders generate electricity from working fluids other than water vapour. In terms of engineering, ORC-based processes rely on turboexpanders with a radial turbine design. Pumps and Compressors for the World Market with Compressed Air and Vacuum Technology 2014

COMPRESSORS, COMPRESSED AIR & VACUUM TECHNOLOGY Geothermal energy – renewable energy source with future potential Heat from geothermal resources is considered a renewable and clean energy source. The world’s first geothermal power plant was built in 1913 in the Tuscan town of Lardarello, Italy. Today, installed capacity of global geothermal energy generation has grown to 11 GW. Major drivers behind the exploration of geothermal energy generation are measures to halt climate change and related efforts towards the reduction of greenhouse gases. Since high-enthalpy geothermal resources in close proximity to metropolitan areas are, for the most part, already being leveraged for energy production, the market is increasingly focused on low-enthalpy resources. Faced with rising market prices for renewable energies, companies are willing to make larger, more targeted investments, mobilizing larger technology budgets in the process. Organic Rankine Cycle – unlocking geothermal resources with low enthalpy One of the key technologies behind the growth of the geothermal energy market is the Organic Rankine Cycle (ORC). This thermodynamic process allows for generating electricity from heat sources, in which the temperature gradient between heat source and heat sink is too low for powering a traditional condensing steam turbine. However, using ORC technology as an alternative also requires higher investments. The current installed base of ORC-driven power When it comes to energy production from geothermal heat sources, the market is increasingly focused on low-enthalpy resources.

InnovatIons & trends The process air demand of a wastewater treatment plant can be produced with highest possible energy efficiency when it is implemented by various machine types with different ratings. Process air production with highest energy efficiency Stephan Brand In biologically working municipal and industrial wastewater treatment plants the production of oil free process air requires a considerable amount of electrical energy. However, an optimal solution with highest possible energy efficiency can only be achieved when the compressor performances can be adjusted continuously to the alternating consumption due to unsteady waste water quantities and degrees of pollution. Pumps and Compressors for the World Market with Compressed Air and Vacuum Technology 2014

39
As the consumption not only varies due to the highly fluctuating load in the morning or late at night, but also by additional waste water from industrial plants working during the week and by alternating amount of precipitation. Often seasonal situations need to be considered, e.g. as for holiday areas. Another important influencing factor are high temperature differences e.g. by summer- and winter operation or in regions that are known for extreme amplitudes such as Canada, Russia or others. Only when all criteria are considered for the conception of the process air production, the optimum compressor system will be chosen in the correct configuration. However, the required process air can only be produced with highest-possible energy efficiency when the selected concept has a sufficiently variable performance spectrum and when an optimal selection of basic- and peak load systems will be fully automatically activated demand-related. Advertisement Increase of the efficiency of the products and their components. Selection of the right solution and In biologically working big sewage plants turbo compressors are often first choice due to their high conveying quantities. optimisation of the installation between air consumer and air generator. Regulation of the air Preconditions for an efficient process air production An essential base for the optimal operation of a biologically working wastewater treatment plant is the demand-related supply of oxygen in the aeration basins in all load situations in accurately dosed quantity. As for the optimal work of the bacteria neither a too much nor a shortfall of process air is to be avoided. Therefore, for a process air production with highest energy efficiency two preconditions are indispensable: generator in adjustment to the air demand. • • The total performance of all installed process air producers must cover the maximum demand of oil-free process air, including a sufficient redundancy service. The technology of the installed plants must enable fully-automatically a flexible adjustment of the process air producers to strongly alternating consumption, with minimum maintenance effort and with minimum idle times. These days, oil-free turbo compressors, positive displacement blowers and rotary lobe compressors are operated in biologically working wastewater treatment plants for the supply of oxygen. Oil-free screw compressors having operated in the meantime or oil-injected plants with subsequent oil-free treatment of the produced process air are these days only operated in exceptional cases. Currently, turbo compressors are mostly used in biologically working big sewage plants as this compressor system distinguishes itself by high conveying quantities, whereas the maximum pressure of 1.0 bar is absolutely sufficient. However, the technology of the turbo compressors has been improved decisively by the providers since the eighties step-by-step. ENERGYEFFICIENCY Our know-how for vacuum pumps and compressors.

InnovatIons & trends Reducing carbon footprint with the right vacuum system Josef Karbassi The consumption of fossil fuels is one of the main causes for the increase of CO2 in the atmosphere. Today, electricity is still primarily generated by power stations fired by gas, oil or coal. Reducing electricity consumption in industrial systems can therefore make a great contribution to improving the carbon footprint. One approach is to review the use of vacuum systems for material handling procedures. Here ultra-modern technology can clearly reduce energy consumption and improve the carbon footprint.
