Pump industry insight from


In everything we do, we never lose sight of what it‘s all about for you: economical work and easy handling.

Whether chemical substances, oils or media for the food industry, it is important to fill or empty quickly and precisely. Due to the reversible conveying direction, both processes can be carried out with just one pump.

As a result of their compact yet powerful construction, Vogelsang rotary lobe pumps are among the most frequently ordered pumps in many UK industries. They transport highly viscous or aggressive media of all kinds and even pump liquids with rough solids without blocking.

Iwas saddened to hear of the passing of Maurice Yates, a figure well known in the pump sector for inventing the Yatesmeter system for thermodynamic measurement of pump efficiency. Maurice was a true innovator and will be sorely missed.

Innovation is a constant in the pump sector, despite suggestions otherwise from some quarters. Yes, the basic physics behind pump operation can’t change, but every other aspect of a pump system can, and innovation in how systems are designed, installed, controlled, monitored and maintained is happening every day.


This innovation is particularly evidenced by the amazing finalists in the Pump Industry Awards, which take place just days after this issue is published. You can find details of the finalists on page 10 of this issue, and we will be reporting on the winners in our next issue.

A key factor driving innovation in our sector is collaboration, something the BPMA works hard to support and encourage within the UK. Beyond our shores, this is a focus for Europump, the European pump association representing 15 national associations including ours. The BPMA is honoured to be hosting the Europump annual meeting as it returns to the UK in May this year, and you can read some of what is on the agenda on page 8 of this issue. This popular event brings together delegates from across Europe to network, learn and share as the pump sector looks to work together to navigate the complexities and explore the opportunities in pump manufacturing and distribution.

I feel sure that, with a drive for continued collaboration, within and across organisations, and the vision, passion and enthusiasm of innovators like Maurice, there is plenty more innovation to come from the pump sector.

CHEMUK 2024 EXPO announces the Process & Chemical Engineering Show Zone

THE CHEMUK 2024 EXPO WILL return on 15 and 16 May at the NEC in Birmingham. Running as part of the trade show, event organiser UK Industry Events has announced the launch of the new Process & Chemical Engineering Show Zone.

The Process & Chemical Engineering Show Zone will be the UK’s only event that brings process engineers from the chemical, food & beverage, pharma, oil & gas, and water & wastewater industries together to experience the very latest innovation that is shaping and inspiring the process industries under one giant roof.

The new focused event zone will present hundreds of specialist process engineering suppliers to attending process professionals involved directly in the design, development, management, and maintenance of operations in the processing of liquid, solid, powder, and gas-based process engineering industries.

Managing Director of UK Industry Events, Ian Stone, explained the decision to introduce the focused show zone. “The Process & Chemical Engineering Show

Zone will give attendees the ability to survey the wealth of new technology and products that are available but also to be able to share that knowledge across the various vertical industries that are the application areas for process engineering.

“Process engineering is, of course, in essence chemical engineering in as much as it is the application of chemical unit operations and unit processes. So, there is an ‘esprit de corps’ among all major process engineers, often coming

through a classically chemical engineering educational base.”

The organisers have also confirmed that the BPMA team and seven BPMA members will be exhibiting as part of the show. Visitors will be able to meet with ABB, Crest Pumps, Flux Pumps Int (UK), Grundfos, EagleBurgmann, March May, and Vogelsgang at the show this May.

Details of the expo and free badge registration can be found at the event’s website www.chemicalukexpo.com.



Ltd is celebrating 20 years of trading in the UK.

The business was established in the UK in 2003 after several industries showed significant interest in its elastomer-coated rotary lobe pumps, the pump Vogelsang invented in 1970 and is best-known for manufacturing globally.

Since then, it has grown to an 18-strong team located across the UK, from Scotland to the South Coast and is headquartered in Crewe, Cheshire. It remains wholly owned by its parent company, German-based and family-run Vogelsang GmbH, which has a global annual turnover of over €170 million.

Vogelsang is a leading provider of pumps, macerators and other machinery for companies across the UK, including rotary lobe and progressive cavity pumps, and XRipper macerators.

Commenting on the anniversary, Jonathan Gutteridge, Managing Director, said: “We are pleased to have reached this milestone in Vogelsang’s story. When it was founded two decades ago, we had a tiny customer base and were almost unheard of as a pump brand. Now we have a turnover of over £10 million and have developed a reputation for making highquality machinery.”

The company has ambitious plans to grow further in the coming years and is on track to increase its turnover as it

branches out into more industrial sectors with its new pump and machinery designs. It has launched several new products over the past 12 months, including the EP and VP rotary lobe pumps, which are designed for heavy-duty chemical industries and can withstand media temperatures of up to 200°C and operating pressures of up to 10 bars.

The company also launched the HiCone progressive cavity pump, with a patented conical rotor and stator design, which means the rotor position can be adjusted as the stator wears, significantly reducing the spare parts usage and maintenance costs.

IN WHAT IS BELIEVED TO BE A global first, the Japanese machine tool manufacturer, DMG Mori, has supplied AESSEAL with energy-friendly machine tools designed to work directly at European standard voltages, avoiding a wasteful transformation step.

DMG Mori has delivered £3.97 million worth of cutting-edge machine tools to AESSEAL plc’s Rotherham-based ‘Factory for the Future’. The machines work directly at 400V 3-phase, used by industry throughout Europe and the UK. All previous machines of this calibre were produced to the Japanese 200V 3-phase electrical standard and required step up transformation to UK voltage, with a loss of approximately 5% of the energy used in the transformation.

Dr Masahiko Mori, the President of DMG Mori, stated: “Many of our machine tools are used globally, and it makes

sense to modify our production lines for new machine tool models for global customers. The four machines supplied to AESSEAL in October were the first we produced to the new 400V 3-phase standard.”

Chris Rea, Managing Director of AESSEAL, added: “Our ‘Factory for the Future’ is an investment in our company, and with the assistance of DMG Mori, the equipment used will now be more environmentally friendly. The total investment in robotic production, the four new machine tools just installed and those due for delivery early in 2024, is £15.5million, making a great start to filling a factory that is both a showcase for responsible industry and a fantastic working environment.”

The £3.97 million machine tool order is in addition to the recently reported £9.75 million order for state-of-the-art robots which are designed to free up the Rotherham company’s workforce for higher value tasks and maintain the company’s competitiveness in global markets.

THE BRITISH PUMP MANUFACTURERS ASSOCIATION (BPMA) has taken note of the recent announcement by Minister Hollinrake regarding the extension of CE marking recognition in the UK market. Following the Department of Business and Trade’s August 2023 declaration of continued recognition for certain product regulations, this development prompts reflection and analysis from the BPMA on its implications for the pump sector.

Minister Hollinrake’s announcement confirms the extension of CE recognition for three key regulations:

• Ecodesign for Energy-Related Products 2010 Regulations (Department for Energy Security and Net Zero)

• The Explosives Regulations 2014 (Department for Work and Pensions - Health and Safety Executive)

• The Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations (RoHS) 2012 (Department for Environment, Food & Rural Affairs)

Regarding RoHS, a nuanced approach is outlined as follows:

• Products meeting the maximum concentration values as per Annex II to the EU RoHS Directive (2011/65/EU) will continue to be recognised under current EU regulations and CE marking.

• Products relying on exemptions will also retain recognition under current EU regulations and CE marking, provided there is a corresponding exemption under the UK Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012.

The announcement also introduces notable adjustments:

• Permanent labelling flexibility allowing importers to indelibly supply their details on accompanying documents, packaging, or adhesive labels.

• Introduction of digital labelling options, enabling manufacturers to incorporate the UKCA marking, manufacturer details, importer details, and declaration of conformity via methods such as QR codes attached to products.

• Implementation of a ‘Fast track UKCA’ process, permitting manufacturers to use the UKCA marking to demonstrate compliance in Great Britain with either UKCA or EU product requirements.

Reflecting on these developments, Wayne Rose, CEO of the BPMA, remarked: “The extension of CE marking recognition and the introduction of new labelling options demonstrate a commitment to facilitating trade and ensuring compliance. However, it’s essential for regulatory bodies to provide clear guidance and support to industries navigating these changes to maintain standards and promote innovation.”

BPMA welcomes new members

THE BRITISH PUMP MANUFACTURERS ASSOCIATION (BPMA) has welcomed three new members into its ranks.

The first is Oxfordshire-based Ambic Equipment, which designs, tests, manufactures and assembles a full range of peristaltic pumps, dosing and dilution systems. Established in 1977, the company has grown both organically and through a number of strategic acquisitions, including the purchase in 2013 of RF Electronics (RFE), a specialist in the design and manufacture of peristaltic pumps and ancillary products.

IE5 SynRM (synchronous reluctance motor) series sees the launch of a new version that combines the benefits of ultra-premium energy efficiency with highly effective liquid cooling.

Customers can use IE5 SynRM Liquidcooled motors to save energy costs and cut emissions in new projects or as a drop-in replacement for less efficient motors.

A significant advantage of the IE5 SynRM Liquid-cooled motors is that they are much more efficient than the traditional liquid-cooled induction motors and offer significant potential for upgrading with energy-saving technology.

Reliability is improved by highly effective cooling combined with the cool SynRM rotor and cooling ribs on the bearing assembly that reduces the operating temperature of the bearings. This helps to increase the lifetime of this key component and reduce maintenance needs.

The motors are robust, with tight seals to keep out moisture, dirt and dust, and a smooth outer surface to prevent dust buildup. This makes them perfect for demanding applications that require high power density where space is restricted, such as marine propulsion systems and thrusters. Furthermore, the motors do not need fans or ventilation, so they do not disturb the surrounding air or release heat into the local environment. This is a major benefit in processes that are impacted by airflow,

such as rubber and plastics production, and food and beverage applications like chocolate conche machines. With no fans, the motors also enhance the working environment by reducing noise levels.

The high power output of the liquidcooled IE5 SynRM offers increased design flexibility. It can enable a machine to be upgraded to deliver a higher power output within the same footprint, or it can allow for a more compact installation footprint while still providing the same output.

IE5 SynRM Liquid-cooled motors are available in frame sizes IEC 200-315 in aluminium frames, with steel available on request. The versatile design enables the motors to provide exceptional performance over a range of powers from 37 to 710kW

pilot of its digital asset management technology with Anglian Water, Norwegian digital analytics company, InfoTiles, is embarking on an expanded proof of concept programme.

The ongoing collaboration with the UK utility will use its artificial intelligence (AI) driven software to manage roughly 317 biofilters, along with pumps and valves, and will be extended from 24 sites to 100.

The continued partnership establishes the ambition that Anglian Water will be able to move towards fully integrating the InfoTiles technology to enhance day-to-day operational visibility.

Full integration will create betterinformed asset management decisionmaking and allow for further understanding of maintenance prioritisation of water recycling assets.

Approximately 483 data points will be measured across all assets included in the scale-up. The water recycling centres will be chosen based on current model predictions and their ability to send relevant asset data to the InfoTiles software.

The initial 12-month pilot of InfoTiles’


celebrating the installation of its 60th alkali surfactant polymer injection pump for a large Indian exploration and production company.

The first Hydra-Cell seal-less and packing-free API 674 pumps for polymer injection, which were installed within their oil field sites almost five years ago, have been running 24/7 in continuous operation for over 50 months with no interruption to production.

These pumps inject polymer with a viscosity of 20-50cP into the well at a flow rate of 4m3 per hour, with the discharge pressure ranging from 20-100 Bar, depending on the well’s characteristics.

Within some of the sites, the pumps’ flow rates run at approximately 2m3 per hour, with pressure ranging from 50 bar to 140 bar. With the latter, the higher pressure is required as the pump

software monitored the rotating arms of 76 biofilters at 24 sites over a period of six months, to assess whether they were rotating when needed. It also measured sludge blanket levels in final settlement tanks to monitor optimal ranges for effective operation.

The data was collected through a mix of new and existing sensors via supervisory control and data acquisition control (SCADA) systems. This was combined with flow rates and publicly available weather data, to build a rich contextual overview of what was happening at Anglian’s water recycling plants in real-time.

InfoTiles also combined Anglian Water’s existing SCADA systems into one event-streaming platform that aggregated, compared, and visualised the reliability of the equipment.

The strength of the InfoTiles platform is the ability to visualise and model process data through machine learning to show the likelihood of critical failures in wastewater treatment, such as potential stoppages and breakdowns.

When fully integrated, this will allow Anglian Water to easily trial and compare different sensor technologies for reliability and accuracy.

During the initial pilot phase, 14 machine-learning models were used to identify biofilter deviations and identify whether failure or slowdown was imminent. Four models were selected and brought forward for further development due to their ability to scale.

is running at ground level, injecting the polymer 1700m below the surface.

Because of Hydra-Cell’s very low-shear pumping action, polymer consumption can be reduced by up to 15%. The unique valve design enables the low shear pumping action, minimising the polymer shear, and optimising polymer usage. With no dynamic seals, the pumps ensure the polymer is 100% contained and with no leakage there is no waste and the polymer is free from oxygen, which stops degradation.

For the first 14 pumps installed, the typical maintenance was less than $3,000 over five years, equivalent to just over $40 per pump per year. A plunger pump with dynamic seals and packing would have incurred costs of almost $6,000 per pump in a year, as estimated by the manufacturer themselves.

Wanner Hydra-Cell pumps are designed for 25+ years’ service life with

ease of repurposing for other duties. They are very simple to service, with no special tools required for “in-field” inspection of the liquid end. HydraCells can run dry indefinitely and are self-priming. They are highly efficient, with more than 90% energy delivery from pump shaft to hydraulic power, achieving significant energy savings.

By combining optimal hydraulics and wearresistant materials in a pump replacement, Sulzer has helped a phosphate fertilizer producer to increase productivity with its AHLSTAR WPP end-suction single-stage pump.

Phosphoric acid is produced with a hemihydrate process, which is considered very severe for the rotating equipment installed in the reactor. The relatively high phosphoric acid concentration and impurities combined with the elevated reaction temperature create a very aggressive environment.

A slurry filter feed pump plays a very critical role in a phosphoric acid plant. A failure will directly impact the plant’s production rate, which is why robust and reliable equipment with the longest possible lifetime was considered to be of prime importance in this application.

Sulzer selected an AHLSTAR WPP53-100 single-stage process pump for the site. The WPP pumps are designed to be extremely wear-resistant and especially suitable for abrasive and erosive industrial applications. The series offers a comprehensive material selection, and the pumps can be tailored to suit the most demanding industrial applications with accessories such as shaft sealing solutions and heavy-duty bearing units.

The previous pumps were made

of a material that is very commonly used in phosphoric acid applications, CD4MCuN. This duplex stainless steel can give acceptable results in some applications of a dihydrate process, but it is not one of Sulzer’s solutions in a hemihydrate process. In this case, the company prefers a higher-grade alloy, 654 SMO. This material, classified as 6%Mo super austenitic stainless steel, has an excellent resistance to corrosion by hot acid with a high chlorides content. It is more and more commonly used in the phosphate industry because it combines a very good resistance to corrosion and better erosion resistance than some more common austenitic stainless steels.

the prolonged lifetime of the pump are the wear-resistant design of a semi-open impeller and a casing fitted with a front wear plate.

Due to the modular construction of the new AHLSTAR WPP, only worn parts of the pump must be replaced. In the earlier pumps, the lifetime of the parts subject to the highest erosion and corrosion was very short, between three and six months. Along with the pump replacement, the average lifetime of the parts was increased to 12 to 24 months, reducing the maintenance frequency by up to 75% from what it used to be.

The previous pump at the site was rotating at a speed of around 1,800 rpm, which was too high for this application. A pump with a low speed of rotation and a full-diameter impeller was required — an AHLSTAR WPP53-100 with a significantly bigger impeller diameter than the previous pump was selected. Although the head is fixed, a lower rotation speed contributes to reduced wear. Other features adding to

Given the harsh operating conditions and the vast improvements compared to the former installation, the replacement is considered to be very successful. After a few years in operation, the pump has proven to be such a major upgrade that more pumps at the site are being replaced with AHLSTAR pumps.



GLOBAL MOTORS AND DRIVES manufacturer, WEG, has recently completed the first delivery of three W22 280S/M 110kW 380V V1 vertical motors, with IP67S degree of protection. WEG’s engineering team met this newly achieved IP rating at its manufacturing site in Portugal.

BPMA calls for urgent action on non-compliant circulator pumps

The British Pump Manufacturers Association is deeply concerned by the recent announcement from the Office for Product Safety and Standards regarding the prevalence of non-compliant circulator pumps in the UK market. The revelation that recent market inspections identified 85% of imports of these products as non-compliant underscores the urgent need for action to safeguard consumers and uphold industry standards.

The OPSS states its primary purpose is "to protect people and places from product-related harm, ensuring consumers and businesses can buy and sell products with confidence". In the product regulator's 2022-2023 delivery report, it stated that inspections it had carried out had "revealed non-compliance in over 85% of the circulators" it reviewed.

The findings of the inspections conducted by the Office for Product Safety and Standards (OPSS) are alarming and raise serious questions about the efficacy of current regulatory measures governing circulator pumps.

Non-compliant products not only offer significant reductions in energy efficiency values, but also undermine the integrity of the pump industry and erode trust in regulatory processes.

Consumers who have unknowingly had non-compliant circulator pumps installed can face unexpectedly high bills from unplanned electricity and water usage, as the pumps fail to meet their expected performance standards.

The plumbers installing these non-compliant pumps and the wholesalers who supply them are not to blame. Many of the non-compliant pumps are 'CE-marked' to suggest compliance with European Union standards, but the manufacturers of the dodgy pumps, the majority of which are based in China, use a similar font to the CE mark but use it to reference the pumps being a 'China Export'.


As the leading voice of the pump industry in the UK, the British Pump Manufacturers Association (BPMA)

emphasises the importance of robust enforcement mechanisms to address the influx of noncompliant products into the market. It is imperative that regulatory bodies collaborate closely with industry stakeholders to implement effective strategies for detecting and preventing the circulation of non-compliant pumps. The association welcomes the OPSS's removal [delisting] of some thirty products identified as not satisfying the required compliance measures. But it is calling on the body to redouble its efforts and work to stop the import of non-compliant pumps completely.

decisive action to tackle this issue and ensure that only energy-efficient and compliant products are available in the market."

“The proliferation of noncompliant circulator pumps is a significant concern.”

In response to these developments, the BPMA reaffirms its commitment to promoting excellence and compliance within the pump industry. The association stands ready to collaborate with the OPSS and other relevant bodies to develop and implement measures that enhance product safety and integrity.

Wayne Rose, CEO of the BPMA, commented, "The proliferation of non-compliant circulator pumps is a significant concern for both manufacturers and consumers. We urge the government and regulatory authorities to continue to take

The BPMA urges consumers to remain vigilant when purchasing circulator pumps and advises them to seek products bearing recognised certifications and compliance markings. chevron-circle-right www.bpma.org.uk

Cleaning up energy production

Methane flaring from oil and gas fields is a huge waste of energy and is clouding the reputation of an industry facing increasing challenges due to climate change. flow finds out how a partnership, which includes sealing specialist AESSEAL, has come up with a solution that could solve the problem of flaring and venting from oil and gas fields and help clean up energy production.

The UK Government plans to ban the venting and flaring of gases in oil and gas fields from 2030. And methane was one of the key issues on the negotiating table at the recent COP28 climate talks in Dubai.

This renewed urgency for climate action has meant that AESSEAL and its partner, Torishima UK, have been working for several years to produce an engineering solution to venting and flaring that many experts have been sceptical could be produced to this tight timescale.

The result of that joint design and manufacturing capability is EcoGuard, a highly engineered product ideal for retrofitting in the world's global oil and gas facilities. The solution is now at the prototype testing stage and will be ready to go to market in the first half of 2024 –six years before the deadline.

EcoGuard seeks to eliminate or reduce intermittent and continuous emissions and could be retrofitted to oil and gas facilities worldwide.

In simple terms, EcoGuard is a small but powerful booster pump that transports gas around a rig's compressor in a similar way to a central heating system circulating water around a house. The booster maintains the gas flow during intermittent shutdowns, an established practice that removes the need for deliberate emissions to prevent system contamination. In the inventive step, the booster also keeps the seal clean to stop leakage throughout continuous operation.

A particular target is stopping methane emissions, a gas 80 times more damaging to the climate than CO2

What's the rush? Mark Wilson from the industry body Offshore Energies UK is quoted on Sky as

saying that retrofitting oil and gas installations "would be difficult within the timeframe we're looking at… It could also mean having to turn sites off." Others are suggesting that financial incentives may be necessary. However, since oil and gas are hugely profitable, many industry leaders now realise that the time has come for action.

The EcoGuard project arises from a desire by AESSEAL's internal dry gas seal team to stop this environmentally damaging practice. The company has a patent pending, and chose pump expertsTorishima UK in Scotland as the perfect partner to manufacture the device.

AESSEAL has calculated that approximately 424m³ of greenhouse gases, predominately methane, are currently released into the atmosphere during a single venting or blowdown of a gas compressor.

A single peak load compressor may be shut down and restarted up to 40 times per year. Extrapolate this worldwide, and the urgency becomes clear.

Scotland has close to 90% of UK oil and gas production. In 2019, over one billion cubic metres of gas was flared from Scottish facilities,

releasing 2.9 million tonnes of CO2 equivalent emissions, which was 21% of the total amount of CO2 released in Scotland.

Not only is this damaging, but it is also incredibly wasteful. The gas flared off could have been used for heating and is equivalent to the total energy consumption of Glasgow.

The project was undertaken as part of AESSEAL's 29by29 pledge to invest £29 million by 2029 in projects primarily aimed at improving the environment.

Commenting on the development of EcoGuard, Chris Rea, Group Managing Director of the AESSEAL Group, said: "My interest is in the environment. AESSEAL does not make pumps, and the EcoGuard technology does not use seals, but I would like to turn off the industrial-scale bunsen burners that are destroying the planet for my grandchildren. I will give our competitors a royalty-free licence on a case-specific basis as the environment needs all the help it can get." chevron-circle-right

Prevent recirculation pump failures with water and wastewater drives

flow discovered how the pump cleaning function in ABB’s water and wastewater drives helps prevent damage to wastewater pumping operations.

The Sewage Treatment Plant for Research and Education Das Lehr- und Forschungsklärwerk (LFKW) at the University of Stuttgart in Germany is a facility for wastewater and wastewater treatment and a platform for education, research and demonstration. It is a place where scientists can practically test new wastewater treatment processes comprehensively.

LFKW treats wastewater from the Stuttgart area, including parts of the Vaihingen-Pfaffenwald University area. The volume of wastewater treated annually is around 800,000m³. The pollution load supplied corresponds to a volume of approximately 10,000 inhabitants.

The pump in use at LFKW recirculates wastewater with activated sludge from the aeration tank to upstream denitrification. The solids content in the aeration tank ranges from 4g/l to 5.5g/l. A high-efficiency pump was selected since a continuous-duty pump is used at the location. After a new dual-channel impeller pump was installed, overloads occurred within a few days due to very high current consumption, and the motor burned out on two occasions. The manufacturer came back with information suggesting that contamination and deposits in the pump would have generated these overloads.

The pump had to be replaced three times within two years because fibres and sludge

residues had settled in the gap between the channel impeller and the housing which resulted in increased current consumption, and eventually damaged the motor. The imbalance caused bearings to fail, or the winding would burn out due to high current consumption. Replacing the pump involved a lot of effort each time.

A crane truck was required to lift


To correct the problem, ABB's ACQ580 variable speed drive with 4kW of power was installed for motor control in February 2021. The drive has been specially designed for water > 24

and wastewater applications. The integrated pump cleaning function in the drive is particularly suitable in this situation. It is intended to prevent solid particles from becoming lodged in pump impellers or piping. Traditionally, the blockages would be removed manually, but this requires the pump to be decommissioned and opened.

The pump cleaning function in the ACQ580 consists of a programmable sequence of forward and backward rotations to loosen and remove deposits from the pump impellers and piping. It prevents blockages, making the need for manual cleaning less frequent.

The drive starts the cleaning process by applying a pulse in the direction opposite to the operating direction. The duration of the cleaning pulses is the same in both positive and negative directions. Several cleaning pulses in the positive and negative directions can occur within the same cleaning sequence.


The ACQ580 operates the pump's motor at a frequency of 48Hz. The target is a constant flow rate of approximately 20l/sec, as a uniform recirculation rate is essential for the process. The flow rate should be kept constant to achieve a high denitrification rate.

Since the ABB ACQ580 has been in operation, it is clear that the self-flushing of the pump is working again. The flow rate decreases slightly at a constant speed over the day and increases again after cleaning.

Figure 1 shows how the troublefree operation works. The pump operates at a constant speed, and the drive monitors the power consumption. The pump is usually reversed once a day. If increased power consumption values start to appear, the drive stops, runs an automatic cleaning program and then restarts at the set point speed. In trouble-free operation, the flow rate at constant speed

is the same before and after flushing. Flushing is performed depending on the pollution. So, in the example shown, flushing was run twice on November 3, 2021, and once a day on other days.

If increased pollution occurs, the delivered flow rate fluctuates at a constant pump speed. This can be caused by deposits in the pump chamber, in the wear rings of channel impellers or in the suction or pressure nozzles. Figure 2 shows one such example. After flushing, the flow rate increases and then steadily decreases. Then, the circuit is flushed, and the pollution is rinsed out. This causes the pump to deliver more water again at the same speed.

Figure 3 shows 24-hour cycles without heavy pollution on December 10 and 11, 2021. On December 13, the flushing program started, but the pump did not immediately deliver the desired flow rate since dissolved pollution needed to be rinsed out. The pump will not give the expected flow rate until it has fully rinsed everything out.

The results show operation at a constant rotational frequency. That's why the flow rate fluctuates. If the pump is operated with rotational frequency control and a fixed flow rate, the comparable effect can only be detected in the power consumption and the speed (frequency).


A dual-channel impeller pump at LFKW that pumps recirculation water from the aeration basin to the denitrification basin has seized repeatedly in the past as a result of pollution, resulting in total pump damage. Since installing the ABB ACQ580 water and wastewater drive with built-in pump cleaning functionality, the pump has been running troublefree and with low wear. Overloads did not occur, and bearings no longer needed replacement. The experience gained at LFKW can be transferred to all wastewater treatment plants. If there is a risk of clogging, clogged areas

can be loosened using the pump cleaning function of the drive, and doing so will not block the pump either on the suction side or the pressure side. chevron-circle-right

Leakage-free methanol pumps for alternative fuel solutions

Safe and efficient mag-drive centrifugal pumps, available from DESMI, can enable leakage-free methanol fuel systems for ships, reducing vessel carbon emissions and climate impact, as flow discovered.

With every year that passes, emission regulations tighten in the shipping industry. Shipowners who want to stay in business must look for ways to reduce carbon emissions to comply with the targets defined in the International Marine Organisation (IMO) greenhouse gas (GHG) strategy and other regulations.


Running on alternative fuels is one of the most effective ways of reducing emissions. Methanol provides several key benefits as a shipping fuel, making it one of the most promising alternative fuels: When produced from biomass, green hydrogen, or other zero-emission sources, it enables neutral well-to-wake carbon dioxide emissions. And because methanol stays liquid at ambient temperature and atmospheric pressure, you do not need to invest in complex high-pressure or lowtemperature systems to use it.

However, methanol is also toxic and highly flammable, which prompts safety considerations when selecting and installing a fuel infrastructure for ports and ships. Specifically, you must ensure the fuel system is absolutely leakage-free to avoid hazardous situations.


DESMI's new mag-drive centrifugal pumps are well suited to operation in a methanol fuel system. They combine the high efficiency and robust reliability of centrifugal pumps with a magnetic coupling, eliminating the pump's traditional shaft seal solution. As the pump chamber is

completely sealed, there is virtually zero risk of methanol leakage.

While the magnetic coupling is a new feature on its centrifugal pumps, the technology itself is not new to DESMI.

"We introduced magnetic coupling technology in the 1990s, so we're building on three decades of solid experience here," commented Martin Bro, Global Sales Manager, Gas Systems, at DESMI.

The DESMI mag-drive centrifugal pump is ideal for methanol fuel systems on new-build dual-fuel ships and can also be retrofitted on existing vessels. It is part of a complete portfolio of marine pumps, which covers a wide range of applications.

"We can supply pumps for the entire fuel pathway, from bunkering vessel to engine room," added Martin. "In addition to mag-drive centrifugal pumps for methanol transportation, we offer pumps for applications such as boosting, draining, and water heating. And we always look beyond the pumps and work with our partners and customers to design a solution that fits the specific requirements to the letter."


The new pump from DESMI is specifically designed for marine applications and comes with a lengthy list of class approvals and certifications, for example ABS, BV, CCS, DNV, KR, and LR. Built for compliance with the IGF Code, it is designed to meet the rigorous safety standards for ships using gases or other low-flashpoint fuels, and for installation in ATEX zone I if required. Its built-in temperature sensor detects overheating and helps avoid

breakdowns, and it can be specified with a leakage sensor.


In addition to setting an ambitious net-zero emission target by (or around) 2050, the IMO has declared that by 2030, the carbon intensity of ships must be reduced by 40% compared to a 2008 baseline. Using methanol and other alternative fuels is an efficient way of reaching both targets, even though these fuels are sometimes hazardous.

"It's ironic that methanol, which can really reduce the climate impact of the shipping industry, is itself so toxic and flammable," concluded Martin. "But that's the reality, and with the right technical solutions, these challenges can be overcome. We're dedicated to sustainability and energy efficiency, and we've worked to reduce the climate impact of shipping for decades. I'm confident that the mag-drive centrifugal pump will help us continue this evolution and contribute to a better future." chevron-circle-right

Piping design for Food and Beverage applications

Several factors need to be considered when designing the piping element of a pumping system, and in the food and beverage sector, there are specific considerations related to hygiene. Chris Callander outlines some best practices in piping design to meet stringent regulatory standards and achieve high-quality production outcomes.

The piping design for a pumping system to be used in the food and beverage industry is critical for maintaining product integrity, ensuring safety, and optimising operational efficiency. Let’s look at several key areas which include material selection and standards, hydraulic considerations, layout optimisation, flexibility and monitoring.


In many food and beverage applications, stainless steel is preferred for its corrosion resistance, ease of cleaning, and nonreactive properties, which can be crucial for maintaining product purity.

Food-grade plastics may be used in specific scenarios where flexibility and corrosion resistance are critical, but with caution regarding wear and chemical compatibility.

Establishing which standards are relevant to your sector and application is important. These will often affect material selection and other aspects of system design. For example, 3-A Sanitary Standards and EHEDG Guidelines ensure equipment design promotes hygiene and is easy to clean and sterilise. While ASME BPE guides the design of bioprocessing equipment, which is applicable in many food and beverage processes.


Correct pump and pipe sizing avoids issues like cavitation and excessive wear. The design of a system should employ hydraulic calculations to match the pump capacity with system requirements, considering factors such as fluid viscosity, density, and flow rate.

Maintaining optimal flow velocity helps to prevent sedimentation in lowvelocity areas and erosion in high-velocity sections. Recommended velocities vary by application but typically range between 1.5 to 3m/sec.


Incorporating straight runs before and after critical components helps to reduce turbulence and facilitate easier maintenance. In addition, the layout should be designed to allow easy access to all equipment and valves for cleaning, maintenance, and inspection.

Sloping piping correctly is also important to promote complete drainage, a critical aspect in avoiding bacterial growth and cross-contamination.


Piping should be designed with Clean-InPlace (CIP) systems in mind, ensuring that all parts of the system are accessible to cleaning solutions without dismantling. Features like spray balls for tanks and appropriate connections for CIP systems to circulate effectively should also be included in the design.


Adopting a modular design approach allows for easy expansion or reconfiguration of the piping system as production needs evolve. While using standardised components helps to facilitate quick changes and minimise downtime.


Integrating sensors and flow meters for realtime monitoring of pressure, temperature, and flow rates makes it possible to ensure the system operates within specified parameters.

While implementing automation solutions for critical control points can enhance precision and reliability in product quality.


Designing a piping system for food and beverage processing is a complex task that demands a strategic approach to material selection, layout optimisation, and system integration. I have only been able to give the briefest overview here, and I would recommend talking to a specialist, such as your pump supplier, before starting the system design process if you are unsure of any of the areas mentioned above.

But, by adhering to industry standards and incorporating best practices in hydraulic design, cleaning, and monitoring, businesses can achieve a highly efficient, safe, and scalable pumping systems. This not only ensures the quality and safety of food and beverage products but also enhances operational efficiency and sustainability in the long run. chevron-circle-right

Reliable handling of viscous fruit concentrate

Fruit juice manufacturer SOKO Gorica has increased the efficiency of its production process by replacing a pump that failed to transfer highly viscous peach concentrate with reliable Bredel 25 hose pumps.

SOKO produces over 30 million fruit drinks a year with a process based on high-capacity automatic equipment and certified with an ISO 22000 quality management system. However, due to a pump from another manufacturer being unable to handle the viscosity of the peach concentrate, SOKO had to revert to manually transferring the product, adding water and reprogramming software to adjust the recipe. This slowed the process at SOKO’s production site in the Republic of North Macedonia as more time was spent preparing the production and the recipe.

Peach concentrate of 32Bx (degrees Brix) and a volume of 1,14kg/m3 was not being pumped from the aseptic drum, because the viscosity was too high for the pump size to handle.

Unhappy with the support it received from the pump manufacturer, SOKO contacted Watson-Marlow Fluid Technology Solutions (WMFTS) to discover what alternative pump solutions it could offer. WMFTS recommended a Bredel 25 peristaltic hose pump with an F-NBR food contact hose (compliant with EC1935/2004 and FDA 21CFR177.2600 and meeting 3A standards) for the application of unloading fruit concentrate and puree from an aseptic drum to a production process tank. This involves a recipe of 20kg of juice concentrate mixed with water and additives (vitamin C, sodium citrate, aroma), depending on what juice is being produced.

Alan Varelija, WMFTS sales engineer for the Balkans region, said: “I wanted to assure the customer that our solution would work, and after consultation with SOKO and our experts, we decided to send one of our demonstration pumps for a trial at SOKO. The trial results were exceptional, so the customer had no doubts about the purchase.”

SOKO uses the Bredel pumps to handle highly viscous peach and banana

concentrates (4000-5000cP) and other fruit concentrates (approximately 3000cP). Since purchasing the Bredel pumps, SOKO’s preparation time has been shorter, with better hygienic conditions and a more efficient process than the manual preparation adopted when the previously used pump failed to transfer peach concentrate.

As the peach and other fruit concentrates are now being transferred quicker, SOKO uses less energy and has reduced its energy costs. The Bredel 25 also does not vibrate like the previous pump, which affected the stability of the surrounding infrastructure at the production site.

Nikola Karanfilovski, Technical Manager at SOKO, said: ‘’With the previous pump, we didn’t manage to pump very viscous peach concentrate from drums. This problem meant we had to prepare recipes manually, adding water and reprogramming software to adjust all ingredients. With Bredel, pumping is smooth, and we don’t have the time-

consuming manual job. We can now finish recipes with simpler manipulation, with better hygienic conditions, and in a much faster time than before.”

Using direct coupled technology, Bredel combines the reliability of long-coupled pumps with the compact footprint of close-coupled pumps. The Bredel 25 pumps viscous and abrasive slurries and pastes, up to 80% solids in suspension. It has a repeatable volumetric accuracy of +/- 1%, a maximum flow rate of 2,740l/ hr and a capacity of 0.3l/rev. The pump’s maximum discharge pressure is 16 bar, and it can handle a maximum fluid temperature of 80°C.

SOKO Gorica Ltd exports 95% of its annual production to 30 different countries, including the US, Australia, New Zealand, United Arab Emirates and multiple nations in Europe. chevron-circle-right www.wmfts.com

HAYLEY GROUP IS SET TO PROVIDE that makes machines for the post-harvest processing of vegetables with two new Landia chopper pumps that have special external shredders.

Originally developed to deal with difficult wastewater solids in the fish processing industry, the Landia shredder-propeller design has proved its capability in handling troublesome stringy material such as carrot tops which typically cause problems for standard pumps.

Daniel Moulding, Assistant Manager at nationwide engineering component supplier Hayley Group, said: “The Landia chopper pumps work extremely well for our customers in numerous applications. In this particular challenge, the specialist machinery company asked us for help because their existing pumps struggled with the fibrous and gritty material that is an inevitable part of the wastewater process with vegetables.

“This latest purchase of two new Landia chopper pumps follows orders for five units successfully introduced at various locations during 2023.

“Landia has been very helpful indeed in working with us to understand our customers’ needs, adapting the shredderpropeller so that there is no longer any downtime on the processing lines, which is a huge benefit.”

Howard Burton, Technical Sales Engineer for Landia, added: “For certain effluents with difficult solids, the pre-cutting shredder-propeller adds another important chopping stage, continuously reducing particle size and keeping the process running efficiently.”

Daniel continued: “Besides providing such an effective, reliable solution, Landia also gives us fast and efficient backup whenever needed.

“When our customer first used the Landia Chopper Pump, they said they’d never return to the previous unit type. Another eight pumps later, we and they are delighted with the positive outcome, as are the end-users of the equipment.”

We still have a voice in Europe despite Brexit

FIn the wake of Brexit, Wayne Rose, the CEO of the British Pump Manufacturers Association (BPMA), offers his insights on the evolving regulatory environment affecting the pump industry. He outlines the proactive measures taken by the BPMA and its partners to ensure that all policies implemented are balanced and just for every stakeholder involved. applicable directives, standards and compliance matters relating to the manufacture and supply of pumps throughout Europe and the rest of the World, but it is also able to help steer, guide and question these important legislative activities.

or decades the UK and its manufacturing industry aligned the majority of its product safety and certification protocols with that of Europe, ensuring that both elevated levels of compliance and fair competition were maintained across this vast trading block. In fact, drawing on the vast experience and technical expertise available through our extensive complement of trade bodies, institutions and world-renowned academia, the UK has been instrumental in devising much of the regulatory framework that exists today. Its influence has been profound and far-reaching, and contrary to some views, despite the complications brought about by Brexit, many of the UK’s trade bodies, including the BPMA, still maintain a considerable voice on the international stage.

In the case of my own organisation, which represents the commercial interests of UK and Irish manufacturers and suppliers of liquid pumps and other pumprelated equipment, it is itself a member of Europump, the European Pump Association, which represents 15 National Associations across the continent of Europe. Furthermore, as a founding member, the BPMA has representation on the main Europump Council, holds the secretariat of the Europump Marketing Commission, and enjoys strong representation on both the Standards and Technical Commissions.

As such, and directly through this engagement, the BPMA is not only able to keep abreast of all

Navigating uncertainty: Going forward, the BPMA will continue to maintain ongoing discussions regarding the potential divergence of the UK from existing European standards and directives related to product certification. Insights will be provided on how the pump sector can effectively steer its way through the uncertainty brought about by these potential changes.

The critical role of certification: Emphasising the significance of product certification, the BPMA will continue to highlight the potential implications for manufacturers, suppliers, and end-users. Key to this is advocating high-quality standards to ensure the continued reliability and safety of all pump products and their related systems.

Industry advocacy and collaboration: The BPMA is committed to maintaining a proactive role, along with other partner trade organisations, in providing the UK Government with substantial background information and market feedback to help ensure the longawaited updates fully align with industry needs.

“We are actively engaged in providing insights to policymakers, both at home in the UK and within the EU.”

As we navigate the evolving landscape post-Brexit, it is crucial

for the pump industry to adapt to changing standards. At BPMA, we are actively engaged in providing insights to policymakers, both at home in the UK and within the EU, advocating for updates that will benefit the entire sector. Our collaborative efforts with fellow trade organisations underscore our commitment to ensuring a robust and progressive regulatory framework. For the benefit of our pump manufacturing members, we will continue to lobby all applicable persons and entities to ensure essential safety compliance, improved energy efficiencies, and fair and equitable trading opportunities.
