SEPTEMBER 2016

2016 MARKS THE 75TH ANNIVERSARY OF THE BRITISH PUMP MANUFACTURERS ASSOCIATION

The preceding three quarters of a century has borne witness to enormous changes in both the world of pumps as well as the wider world. Back in 1941 in the UK, we were in the firm grip of World War 2 with all the inherent difficulties that it created. Although many aspects relating to pumping have changed in that time, some of the fundamental engineering principles behind the technology remain today. The current BPMA President is Mr Peter Reynolds of Grundfos Pumps Ltd, who has been at the helm since the start of the year. We recently caught up with Peter and asked to sum up his experience in office to date. “I was delighted with my appointment as President of the BPMA. This was a great honour for me that has been heightened by my having the added good fortune that my term in office coincides with the 75 the Anniversary of the BPMA. With a story that goes back to 1941, the foundations of the BPMA are traceable back to Peat Marwick Mitchell (who provided the P M cornerstones of today’s global accountancy giant - KPMG). Their role was to control the allocation of strategic materials to the industry. By 1965, the BPMA had established its own offices and officers with Sir Peter Parker being the first President. With only five Directors at the helm E.F.E. Howard until 1972, F.D. Outridge until 1982, B.F.Glanfield until 1993, B.Huxley until 2013 when our current Director Steve Schofield took the role, this has allowed for a seamless direction throughout a period that has witnessed great technological change. Such continuity has not been quite so visible and marked in the pump industry itself, as member

companies have come and gone as well as it witnessing a range of take-overs and mergers as has also been reflected in other key industries in modern times, something we can see continuing into the future. Moving from being a standalone institution, the BPMA has joined forces with Europump and this has allowed us to work closely with as well as to influence European strategy. This has led to the deployment of important new standards that have had a major impact on EU legislation including the instigation of important Directives. Indeed the BPMA has historically taken a lead within Europump to develop a variety of strategies, of particular note is the Energy strategy, which drove the greatest change the industry has seen to date from both a national and European perspective. We also maintain a healthy working relationship and share key information with our American Colleagues, the Hydraulic Institute. Since my appointment, there have been some significant political decisions made which will mean more opportunities as well as more challenges for us all as well as the industry. We are already taking steps to ensure that our voice continues to be heard at the highest levels to cement our position of being at the vanguard of change. The role of the BPMA however, goes beyond addressing issues relating to legislation, but also for the past 20 years has provided pump technology training for the wider industry in order to satisfy member and non- member requirements and maintain the highest standards and best practice within the industry. However, I firmly believe that we can look forward to the future with more confidence, as today we have a strong membership base, a firm strategy for the future and the willingness and drive to see projects through”.

BPMA & EUROPEAN SEALING ASSOCIATION SIGN MUTUAL COOPERATION AGREEMENT Established in 1941, the British Pump Manufacturers’ Association (BPMA) is a not-for- profit trade association representing the interests of UK and Irish manufacturers and suppliers of liquid pumps and other pump related equipment. Established in 1992, the European Sealing Association is a not-for- profit trade association representing the interests of manufacturers and suppliers of sealing devices and materials across Europe. Recognising the core values of each organisation and the fact that that they already follow very similar technical, standardisation, training, energy and environmental protocols across their respective product areas, it has been determined that a great deal of mutual benefit can be derived from such an undertaking. The agreement will allow the exchange information between the two associations in areas of common interest affecting pumps, pump sets and sealing products , which could include but will not be restricted to:• Technical issues • Standards (UK, European and International) • Legislation information (European) • Energy and Environmental issues across Europe • Training Programmes (and their respective promotion) Having been approved by the Council of each organisation, the agreement was formally signed by BPMA President, Mr Peter Reynolds of Grundfos Pumps UK and ESA Chairman, Mr John Morton of John Crane. Commenting on the signing, BPMA Director and CEO, Mr Steve Schofield said, “this is an exciting development for both organisations, and one which I’m sure will quickly deliver important benefits for our respective memberships”. He added, “with the agreement coming into effect in our 75th Anniversary year, it is a further indication of our commitment to ensuring pump systems excellence across the international arena”

SITUATION IN THE UK POST BREXIT IN REGARD TO CE MARKING It’s likely that it will be at least six months before any clear view of how Brexit will be achieved emerges, and two years before we see any significant changes in UK legislation. Even then, all of the Directives on which CE marking is based are single market measures which are exactly those that the exit campaigners wish to preserve. By voting for exit, the UK has now forfeited a substantial proportion of its influence over how those measures will be developed in the future, but the legislation will remain in place in Europe and UK companies will have to abide by it if they wish to continue to sell into the single market across Europe. As things stand at present, the exit will have no effect on the UK’s participation in the European standards bodies, CEN and CENELEC. The current presumption whereby British Standards are withdrawn in favour of Harmonised European standards has never been mentioned in the debate about Brexit and it seems likely that it will remain for the foreseeable future. Since the majority of the detailed design measures for CE marked products come from standards, there will be little practical change so far as equipment designers are concerned. In the long term, clearly there will be some divergence between UK and EU requirements for product safety. BPMA will continue to work hard to identify what’s actually required in the EU market and inform all our members, what they need to do to legally sell their products. We are confident that our pragmatic approach based on a sound technical understanding of the requirements and a unique strategic understanding of the CE marking process will continue to ensure that our customers’ needs are met.

BOWER BOWS OUT & HOLLINS HOPS ON-BOARD After holding the position for the past 10 years, John Bower of Flowserve has recently retired from the role of BPMA Technical Committee Chairman. As part of this important industry role John also held positions within British Standards Institution as BSI MCE/6 Chairman and as ISO TC 115 SC 1 Chairman. He also sat on many technical committees within Europump as well as updating BPMA Council on various technical matters throughout the past decade. John has been a significant figure in the pump industry who has worked tirelessly for the benefit of all, and he will be sorely missed. The supporting photograph pictures BPMA Director & Chief Executive Steve Schofield wishing John a long, happy and healthy retirement, whilst offering a card and token of gratitude with other members of the BPMA Technical Committee. This presentation took place at the June Technical Committee meeting held at the offices of Collyer Bristow Solicitors in London. The person replacing John Bower in this important role is John Hollins, who holds the position of Engineering Manager of SPP Pumps. Although he has significantly large shoes to fill, John has been a member of the BPMA Technical Committee for a number of years already and so is well versed with the workings of this important group. He is currently responsible for all SPP Pumps products and technical risk. This includes the design, development and testing of new products as well as engineered to order projects with values in excess of £4million. He also has responsibility for risk assessing new products for CE marking and reviewing new designs. He is a member of various industry technical committees and sits on several standards writing working groups for both ISO and BSI. Commenting on the changes, Steve Schofield of the BPMA said, “John’s commitment to the role over the past 10 years has been nothing short o tremendous, and we are enormously grateful for all he has achieved on behalf of the BPMA and of course the wider pump industry. We wish him a wonderful retirement. But at the same time, we welcome John Hollins to the role, who know will continue the important work of the BPMA Technical Committee, as we navigate the unchartered waters of Brexit”.

BPMA POSITION PAPER ON WEEE DIRECTIVE 2012/19/EU “The Directive” means Directive 2012/19/EU of the European Parliament and of the Council of 4th July 2012 on waste electrical and electronic equipment (WEEE) which replaces Directive 2002/96/EC as amended by Directive 2003/108/EC and Directive 2008/ 34/EC of the European Parliament and of the Council of 8th December 2003 on waste electrical and electronic equipment. This can also be referred to as electrical and electronic equipment (EEE) The goals of the WEEE directive are to establish an ecologically sound system for the disposal of waste from electrical and electronic equipment, e.g. computers, washing machines, irons and electronic tools. The directive covers both privately and commercially used electrical and electronic equipment. The revised Directive has increased the scope of WEEE , however an open question still remains as to what extentmechanical engineeringproducts are covered by the WEEE directive. In order to answer this question, and after a more precise analysis of the core text of the directive, members of the British Pump Manufacturers Association agreed the following position. Core Statement: Pumping installations are not covered by the WEEE directive Rationale: Within the revised Directive of 4th July 2012 under Article 2 SCOPE the reference to electrical and electronic equipment (EEE) within paragraphs 1 (a) and 1 (b) and subsequently the Annexes I , II , III IV do not refer to any type of pumping equipment. Furthermore within Article 2 ( scope ) under 4 (c ) it stipulates that ; large-scale fixed installations, except any equipment which is not specifically designed and installed as part of those installations; Under Article 3 (Definitions) under 1 (c ) points i to iii it stipulates the following; Large-scale fixed installation* means a large-size combination of several types of apparatus and, whereapplicable, other devices, which: (i) are assembled, installed and de-installed by professionals**; (ii) are intended to be used permanently as part of a building or a structure at a predefined and dedicated location; and (iii) can only be replaced by the same specifically designed equipment; * We agree with the Environment Agency interpretation of a large scale fixed installation ; “a combination of several pieces of equipment, systems, products and/or components (or parts) assembled and/or erected by a professional assembler or installer” Specifically – Large fixed installation is defined by the pump industry as a complete installation consisting of , pipework , pump and all other related components required to deliver the specified parameters. This industry description also conforms to the Environment Agency interpretation of Components, accessories and consumables. ** A product deemed as requiring professional persons with suitable qualifications for correct installation and commissioning shall be referred to within the manufacturers installation and operation manual which must be supplied with all pumps placed on the market . Conclusion: After careful study of the Directive 2012/19/EC dated 4th July 2012 on WEEE, BPMA and its members come to the conclusion that pumping installations are not included within the scope of this Directive.

ECONOMIC VIEWPOINT - GLOBAL Oxford Economics The surprise UK vote on 23 June to leave the EU caught markets on the hop. There was a strong initial equity sell-off but this has faded – world stocks are already back at their pre-referendum level. Moreover, key global financial stress measures such as equity volatility are not sending danger signals; so this does not look like a ‘Lehman Brothers’ moment. We nevertheless expect economic uncertainty to linger for a while. The new UK-EU relationship will take time to flesh out and – perhaps more significantly – the UK vote seems to have re-focused investors on weak spots in the global economy that have been glossed over in recent months. Our new global forecasts see the economic fall-out from the UK vote concentrated in the UK. GDP growth there is now expected at 1.1% in 2017 and 1.4% in 2018 versus 2.3% and 2.2% a month ago. There will also be negative spillovers to the Eurozone and Japan. In the Eurozone, trade with the UK will be weaker and there may also be a negative impact from heightened concerns about structural weaknesses such as bad loans at Italian banks (18% of loans, equivalent to €360 billion). We expect Eurozone growth to be 1.5% in 2017 and 2018, some 0.2 percentage points lower than three months ago. We also expect weaker growth in Japan. The Brexit vote has added to existing upward pressure on the yen, which is now 21% stronger on a trade-weighted basis than a year ago. We now see Japanese growth at just 0.1% this year and 0.3% in 2017 – despite the delay in the consumption tax rise (previously planned for next year) to 2019. In the emerging markets, the recent pattern of forecast changes has featured some upgrades, in part thanks to improved commodity prices. As a result, despite our UK, European and Japanese downgrades, our latest world GDP forecast for 2016 is unchanged from a month ago at 2.3%, but projections for 2017 and 2018 have been nudged down slightly to 2.6% and 2.9% respectively. UK financial markets endured a period of significant turbulence immediately after the EU referendum, with sterling and equity prices dropping sharply. However, sterling has stabilised over the past few weeks, while most equity indices are now higher than they were immediately prior to the referendum. It will be some time until we have hard data on the impact of the referendum result on the economy, with the July retail sales data set to provide the first indication. There has been a series of sentiment indicators published during July, most of which show a sharp deterioration compared with prior to the referendum. Uncertainty on hold... The rapid appointment of Theresa May as Prime Minister should help to reduce the degree of uncertainty. She has made it clear that she will not trigger Article 50 of the Lisbon Treaty until the government has decided upon its negotiation strategy. Her appointment of high profile Brexiteers to the cabinet positions tasked with negotiating the UK’s departure has strengthened our conviction that we are likely to see a ‘hard Brexit’ resulting in the UK and EU reverting to a relatively loose relationship. Our short-term forecasts for UK GDP growth are 1.8% for 2016 and 1.1% for 2017. Post-referendum we expect heightened uncertainty to dampen business investment, while the weaker pound will push up inflation and hamper consumer spending. But in our view, the UK is likely to endure a slowdown in growth, rather than a technical recession. The Bank of England unveiling a four-pronged package of monetary policy moves to support the economy. While the impact of the individual measures may be relatively modest, taken together they are towards the upper end of the range of what could have realistically been anticipated and reinforce our confidence in our above-consensus forecast for GDP growth.

GRUNDFOS CAN THE CAN

The Grundfos for Engineers Hub is specifically developed to keep our engineering partners with an interest in pump technology informed about the latest developments in the industry, as well as briefed on the wider subject of fully integrated pump systems. One interesting aspect of this new engineering hub allows visitors the opportunity to see and hear from many Grundfos product specialists who discuss a number of industry related topics. The range of topics discussed is broad and covers areas such as heating systems and boiler feed; iSolutions – the Grundfos total systems approach – that offers the opportunity to make a significant impact on overall system efficiency; sensors are also in the spotlight as a topic as is the fact that through differential pressure, they can help reduce costs. This means there will be something just for you whether you are an engineer working within commercial building services, process industry applications or in water supply and/or treatment industries. In addition to these interesting insights there are also a range of technical White Papers, case stories and access to engineering tools that will all help to keep you informed and up to date. This is only a part of the wide range of information that is available at the touch of a button; check it out for yourself by visiting www.grundfos.co.uk/engineers

One of the leading beverage can manufacturers in the UK wanted to find out about the possibilities of saving energy on their installed pump systems so approached Grundfos to undertake an Energy Check. The can wash lines were chosen to be the focus and an Energy Check was undertaken and a comprehensive report on the findings produced. This resulted in an order being placed with Grundfos based on the savings projected by the Energy Check as well as also because of the strength of reputation of the suggested replacement pumps. The order included 6 MTRE 64-8/2 and 8 MTRE 45-2/1 pumps. These MTR pumps are vertical multistage centrifugal pumps designed for pumping of cooling lubricants for machine tools, condensate transfer and similar applications. In addition to the return on investment of just 18 months, the customer will achieve operational savings of £53K per annum and industry-leading reliability for years to come. In fact, so impressed were the customer with the results of the Energy Check, energy savings of 590,000 kwh/y, that they decided to change the pumps, not only on the original can wash line, but on their second line as well.

A GUIDE TO ENERGY EFFICI

Here, Richard Smith at AESSEAL, looks how appropriate selection the energy effic In Europe and the United Kingdom it is estimated that around 10 percent of electrical power is used for pumping equipment 1 , which is a significant part of running a manufacturing operation. One of the consequences of this is that regulatory bodies in the UK as well as plant owners themselves are focussing on improving the energy efficiency of pumps and pumping systems.

MECHANICAL SEALS Mechanical seals can have a significant influence on the energy efficiency of a process. Their purpose is to seal the process fluid - whether it is toxic or expensive, the objective is to keep it within the system and pipe work to avoid it seeping out and resulting in a cost for lost process fluid and clean up. And, of course, if the liquid or process fluid that is leaking is heated, it is losing costly energy from the system. So, be it with flanges, valve stems or pump seals, it is necessary to think of the seal not only as preventing process fluid contamination and leakage to external atmosphere but as an important part of conserving energy within the system.

Figure 1: Frictional power consumption of Mechanical Seals

updates/new-refining-publications/api_std_682

If you are looking at relatively small seals, around 1 to 2 inch (25mm - 50mm) diameter, energy consumption is relatively low 1 HP (0.75Kw) as a maximum 2 . Larger sealing mechanisms can consumer over 3 HP (2.24Kw), as a maximum power absorption. In the grand scale of things this is relatively low, however if the focus is on the thermal inefficiency of seal flush plans the energy that can be lost with inefficient systems can be significant.

ALTERNATIVE FLUSH PLANS FOR SINGLE SEALS

Mechanical Seals, to function correctly, need to be flushed with an fluid to lubricate and keep the seal faces cool. This is accomplished through the use of sealing systems and the various configurations of seal flush plans (API Plans) that can achieve this. Mechanical seals on pumps are probably the most delicate components and we use seal flush plans to change the environment that the seals operate in and that makes them flourish and provide reliable operation. So, in simple terms, flush plans are used to create a stable and idealised environment for the seal, and are formalised by the American Petroleum Institute in their standard API-682, the custodian of the flush plans, where they are detailed in standardised formats. A survey 3 was carried out by the Fluid Sealing Association (FSA) for pumps incorporating a total of 28,000 seals where the process temperature exceeded 200°C (400°F). Figure 3 shows the most popular flush plans used and, by comparison, the energy absorption of each. It is interesting to note that flush plan 32, the second most commonly specified in the survey, is by far the highest energy user. Understanding the flush plans is critical to make an impact on energy efficiency in seal systems and seeing how they control the seal environment. Currently API 682 Standard is in its 4th edition and details over 30 plans to choose from 4 . The Standard has evolved over 20 years and serves as a representative sound engineering practice in the application of mechanical seals. The latest edition has incorporated many of the improvements from the previous editions as highlighted by users. Looking at studies on different flush plans undertaken by the FSA, we compare some of the plans with a hypothetical case study. The single seal flush plans are plan 21, 23, 32 and 62. We will look at dual seals and the appropriate seal flush plans in a separate study.

This is commonly used for high temperature process fluids. API plan 21 takes a simple side stream from the discharge, which is at higher pressure than the seal chamber (at the eye of the impeller). The higher pressure drives the hot liquid through an orifice plate which controls the flow, then through a heat exchanger before this cooler liquid is injected on the seal flush over the seal faces and then is fed back into the process – an open loop cooling system. An issue with API Plan 21 is that the seal flush liquid enters the process and with the process fluid being of a higher temperature this additional cool flush liquid dilutes the process. By comparison, API Plan 23 can be described as a closed loop cooling syste and is probably the most efficient way to remove heat from a mechanical seal. The seal chamber is closed down by throat bushing at the neck of the seal chamber and within the seal chamber is a secondary, very small, impeller, to circulate liquid though the heat exchanger. Plan 23 is significantly more efficient than Plan 21 because only heat from the seal faces and any heat that comes through the pump casing are removed, and no heat is being removed from the process. Plan 32 involves injecting a clean, cold liquid from an external source, through various controls,

IENT SEALING SOLUTIONS

n of mechanical sealing systems can have a significant impact on ciency of a plant. be difficult – often you see installations where the steam is escaping to the atmospheric side of the seal, which dramatically increases the energy requirement, quickly making the system inefficient. Most issues with API Plan 62 steam quench energy efficiency are therefore a result of poor maintenance.

APPLYING THE PLANS TO A TYPICAL CASE STUDY:

through the seal faces and into the process. The flush liquid is generally significantly cooler than the process fluid & effectively this liquid is diluting the process having a significant effect on the thermal efficiency of the process. This scenario can be linked to constantly running the cold water in the bath, whilst trying to keep it warm with the hot tap – the bath water quickly loses temperature.

This is an atmospheric plan commonly used on hot oil type applications for a single seal. With a plan 62, steam is taken across the atmospheric side of the seal and down to a drain system. The steam isn’t really used for cooling but for carrying away any hydrocarbon particles that congeal on the atmospheric side of the face, removing them before they start carbonising and causing the seal and seal faces to ‘hang up’. Plan 62 is a relatively energy efficient method of sealing a hot oil pump. Generally only a very small amount of steam is required however, controlling the steam flow on a steam quench can

It is possible to apply the above API Plans to a hypothetical hot oil pumping application, which illustrates the relative energy efficiency of each. This configuration would be a single stage, end suction centrifugal pump (API 610 compliant), based on: Pumped fluid: hydrocarbon at 315°C (600F) Specific gravity: 0.8 Specific heat: 1.67 kJ-°C (0.4 BTU/lb-°C) System pressure: 345 kPag (50psig) in seal chamber Pump driver: 50 HP (typical) Sealing devices: Compression packing Mechanical seals Assumptions: Heat lost at the pump must be replaced at the system boiler / heat exchanger

To put these figures into context, if a pump is running 24 hours a day, 365 days a year the difference between flushing a seal using API Plan 32 and API Plan 23 can see a business save around 400,000 kW of energy a year. When this saving, which equates to a 96% reduction in energy costs, is spread across multiple pumps and multiple locations thepotential savings are huge.

CONCLUSION To conclude, potential sealing system savings can exceed the energy savings obtained from switching to, for example, variable frequency drives, improving pump hydraulics or trimming impellors, or re-sizing pumps in many applications. Selection of inappropriate sealing systems can have very significant impact on the thermal efficiency of a plant and plant utilities. Sealing systems found in many industrial applications, even when functioning as intended, are extremely wasteful of energy. However, the sealing industry has technologies that can overcome some of this energy wastage and there is increased awareness about these solutions. Improved technology sealing systems available today can reduce the need for energy-wasting systems that result in cooling/dilution of the process and the need for downstream separation/evaporation, re-heating and/or effluent treatment. Being able to choose between different sealing systems or flush plans requires a good understanding of the principals of their operation and why they’re used. The best way to access this knowledge is to work with a sealing partner that has the understanding of this specialist area.

Unlike traditional pumps with rotors that cut through the fluid, Certa’s sinusoidal rotor gently carries fluid through the pump to dramatically reduce shear while cutting power consumption by up to 50% with high viscosity fluids. Engineers in food and beverage plants are frequently faced with pumping high viscosity products, ranging from frozen orange juice, deli salads and bakery produce, through to cheese curd and savoury pie fillings. For many years, Sine® pumps have played an important and highly successful part in conveying foods with viscosities of up to 8 million cP. CertaTM now completes the existing product range by offering users a fully CIP capable pump at flow rates up to 99,000 l/hr. Users can be assured that media is pumped safely and without degradation. FDA and EC1935 compliant Food and beverage plants the world over understand that equipment can play a key role in reducing the risk of contamination and maintaining high quality levels. With this in mind, all contact parts on the CertaTM sine pump are FDA and EC1935 compliant. With the high demand for cleanliness also comes the requirement for simple and fast cleaning, typically through CIP procedures. CertaTM significantly minimises the cleaning time which results in a more efficient production procedure. As well as minimising downtime, this quick procedure also means that chemical and water use is reduced, while less wastewater requires disposal. Performance and reliability Of course, the food-contact compliant Certa Sine® pump also offers all of the typical advantages and high performance levels delivered by proven MasoSine sinusoidal technology. Gentle pumping with virtually no pulsation, superior viscous handling, simplicity, reliability, energy efficiency, interchangeable parts and low cost of ownership all help food and beverage plants compete in a highly competitive marketplace. These benefits apply to all stages of the process, from unloading of the raw material to a storage tank, through transfer to a mixer/agitator/ reactor/cooking vessel, to final transfer to the filling line. Significant benefits over less efficient pumps CertaTM Sine® pumps offer a far better proposition than circumferential piston pumps, for example, which are difficult to clean in their standard configuration. Indeed, for CIP, users will find they have to subject circumferential piston pumps to modifications by drilling the rotor hub which ends up in a performance loss. Certa can also offer significant benefits over less-efficient lobe pumps, as well as twin-screw pumps, which exhibit high internal slip due to bigger internal clearances and therefore offer less gentle handling. Importantly, different applications – resulting in changes to viscosity, temperature, and flow rate - can be easily deployed with one pump setup. This mean there is no need for modifications such as bigger clearances for high temperature applications. Along with certified innovation for food industry applications, the new CertaTM Sine® pump series will provide an ideal solution for F&B, cosmetic or at any facility that requires the highest cleaning standards.

STUART TURNER INTRODUCE FLOMATE IBOOST, THE ULTIMATE SOLUTION TO LOW MAINS WATER PRESSURE Flomate iBoost has been developed to boost the mains supply to larger properties with multiple bathrooms, using high flow combination boilers or an unvented cylinder system, where higher pressure and flow are required. This fully integrated system combines a 200 litre cold water break tank which overcomes restricted mains water flow with a high performance multi-stage pump to dramatically boost pressure. Flomate iBoost is capable of delivering water up to 4.5 bar and flow rates in excess of 100 ltrs/min and is designed to sit alongside other appliances within a kitchen or utility room or can be concealed within any standard 600mm kitchen larder cabinet.

NEW IMPELLER COMBINES RELIABILITY AND EFFICIENCY Against a back ground of growing demands from the water and wastewater treatment industries for submersible motor pumps that resist clogging, deliver reliability and contribute to improving energy efficiency, KSB AG has developed a new centrifugal pump, the Amarex-KRT F-Max (Fig.1)that addresses these issues. Improved hydraulic system and motor performance are delivered through the design of a new vortex impeller and a motor that offers efficiencies currently calculated according to the same IEC 60034-2 measurement method as that used for motors of dry-installed pumps. In order to attain a pump’s optimum operating point, it is essential to select the correct impeller and size of impeller for the application. Whilst free-flow or ‘open’ impellers enable suspended solids in wastewater to pass more easily through the pump than closed single channel or multi-channel impellers, they do not compare favourably when it comes to performance. It is for these reasons that KSB has focused on designing an open impeller that can achieve and even exceed the efficiency levels associated with single-channel impellers. To improve overall efficiency, KSB has looked optimise the motors & efficiency in anticipation of future standards and market requirements is in compliance with IE3.This has enabled KSB to markedly reduce energy consumption.
