Amarinth moves one step closer to developing high efficiency centrifugal pump with Carbon Trust award

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 successfully completed Phase 1 in developing a new process for manufacturing impellers optimised for best efficiency point to better match pumps to the customer’s duty point. The work is being supported through a grant from the Carbon Trust of £160,000.

Today, Amarinth moved one step closer to developing 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 as it completed Phase 1 of a project supported by the Carbon Trust. The work undertaken has also proven that being able to provide optimised impellers will reduce annual CO2 emissions in Amarinth’s target market by 17,000 tonnes by 2020 and 110,000 tonnes by 2050.

Amarinth is the lead organisation in the High Efficiency Centrifugal pump (HEC-pump) consortium working with Furniss & White (Foundries) Ltd and Pera Innovations Ltd. The project, which is due for completion in June 2011, aims to reduce impeller design lead time by 25% and impeller foundry pattern costs 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.
During Phase 1 of the project the consortium analysed four case studies of live contracts in detail. The case studies show the actual pumps sold operated between 4.5% – 16% away from the pumps BEP. The reason a “fit to curve” pump was originally sold is that it is not currently commercially viable to design an impeller for every customer’s specific duty point.

Following the evaluation of a number of software solutions, the consortium chose CF Turbo and ANSYS as the best packages for rapidly designing impeller vanes and volute cores and undertaking CFD analysis to accurately predict the curve shape of a pump along with its efficiency. Initial tests using these software packages show that the software based design lead-time provides savings of around 66% over conventional design lead times.

The four case studies also showed that if the consortium had been able to offer an efficient pump, rather than a standard one, carbon savings of 11,220 tonnes / year could have been achieved (or an average of 2,805 tonnes per pump) with potential total energy savings in the region of 24%.

Having demonstrated rapid and cost effective impeller design process is possible, the consortium will move onto Phase 2 of the project which is to develop commercially viable pattern equipment. This will be followed in Phase 3 with the production of prototype impellers which will then be production tested in Amarinth’s new state-of-the-art test bay facility.

Oliver Brigginshaw, Managing Director of Amarinth commented: “We are very pleased with the outcomes from Phase 1 of the work which has proven that significant savings are possible by using optimised impellers and that technologies are available to reduce impeller design time significantly. We are looking forward to working on the next phases of this project with our partners in the consortium to bring to reality a significant reduction in the carbon footprint of pumps.”

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.
