FOR IMMEDIATE RELEASE – 10 September 2009

Amarinth awarded Carbon Trust grant to develop high efficiency centrifugal pump

Amarinth, a leading company specialising in the design, application and manufacture of centrifugal pumps and associated equipment to the industrial, chemical and petrochemical industries has been awarded a grant from the Carbon Trust of £160,000 to develop a new process for manufacturing impellers optimised for best efficiency point to better match the pumps to the customer’s duty point.

Amarinth aims to develop a cost effective and rapid process for the design and manufacture of bespoke best efficiency point (BEP) optimised impellers for use in industrial pumping applications. Amarinth will be the lead organisation in this project, which is due for completion in June 2011, and will work with Furniss & White (Foundries) Ltd and Pera Innovations Ltd.

The project aims to reduce impeller design lead time by 25% and impeller foundry pattern cost to 10% of current production methods with a lead time of less than a week. The resulting impellers will reduce energy consumption by between 10% and 25% compared to ‘fit-to-curve’ pumps. It is estimated that this project could reduce annual CO2 emissions in Amarinth’s target market by 17,000 tonnes by 2020 and 110,000 tonnes by 2050.

End users generally select centrifugal pumps for particular applications by matching the required pumping parameters to performance curves produced by manufacturers. However, is estimated that about 50% of these pumps operate between 10% and 40% away from BEP (i.e. the maximum efficiency). The key to pumping efficiency is to design the pump’s impeller to match the pumping requirement exactly, which has the potential to reduce energy consumption by between 10% and 25%.

Producing bespoke impellers is not usually commercially viable however because it can cost three to five times more than ‘fit-to-curve’ impellers and they are generally on a significantly longer lead time.

The project aims to develop a new process for manufacturing impellers optimised for BEP at the customer’s duty point. The work will involve:
• Carrying out industrial research for the design and testing of optimised impellers
• Developing a rapid and cost effective impeller design process
• Developing the commercially viable pattern equipment
• Carrying out the mould making and casting of optimised impellers
• Developing an alternative method of fusing the impeller materials base and optimised impeller.

Oliver Brigginshaw, Managing Director of Amarinth commented: “We are delighted to have been awarded this grant from the Carbon Trust for undertaking a project that we have thought long overdue. We have a number of ideas to achieve the project aims of significantly reducing the carbon footprint of pumps and look forward to working with our partners over the coming years in delivering this.”

Amarinth Pump Manufacturing

Amarinth is a carbon net zero organisation delivering world-leading expertise in the design, application and manufacture of centrifugal pumps and associated equipment for critical applications in many of the most arduous and hostile environments around the globe.

Founded in 2002, Amarinth has harnessed the skills, creativity and passion of people who have worked in the pump industry for decades, delivering bespoke API and ISO pumps primarily to the offshore and onshore oil & gas industries; nuclear and renewable energy generation; defence; desalination; process and industrial markets.

The company’s innovative approach, business agility and use of sophisticated computer applications enables it to deliver robust, reliable and sustainable pumping solutions on the shortest lead times in the industry.

Process pumps – API 610, API 685, ISO 5199 horizontal, vertical and in-line bespoke process pumps, including ones that are hydraulically and dimensionally interchangeable with the former Girdlestone and other obsolete pumps.

Skid packages and modules – Supplied with a variety of drives for applications including de-sanding, mixing, filtration and chemical injection and tailored for the oil & gas, water treatment and power generation industries.

Condensate recovery – Cutting-edge design providing low NPSH up to 98°C with variable speed drives to reduce cycle time and lower operating costs, available in stainless steel, galvanised or copper tanks for light or heavy industrial uses.

Seal support – Integrated pressurised and vented seal support systems designed and delivered to API 682 and ISO 5199 standards and specific site specifications and requirements, working closely with AES, Eagle Burgmann, John Crane and Protect System.

Spare parts – Critical spares for all Amarinth pumps and related components can be dispatched the same day, reducing potential downtime, and in addition components for the former Girdlestone and other obsolete pumps can be re-engineered often improving the performance of existing assets.

Services – A full range of pump related services, delivered from UK head office or on-site globally, onshore or off-shore, including full commissioning and start-up support; also strip, report and refurbishment of any pump regardless of manufacturer.

Amarinth operates globally from its base in Rendlesham Suffolk, United Kingdom and offices in the Middle East and Malaysia with a global customer base, including BP, Shell, ADNOC, NOV, ExxonMobil, Schlumberger, COSCO, EDF, GlaxoSmithKline, Saudi Aramco, Pfizer, Diageo, Kuwait Oil Company, AMEC, Fluor, LUKOIL, Halliburton, and Babcock.
