Comprehensive refurbishment by Amarinth of third-party OEM pump (photo: Amarinth)

Amarinth, specialists in the design, application and manufacture of centrifugal pumps and associated equipment to the oil and gas, petrochemical, chemical, industrial and power markets, has expanded its range of pump services to include the strip, report and refurbishment of industrial single stage end suction pumps, regardless of the original equipment manufacturer.

Natural wear patterns of all pumps dictate a reliable working life of some 15 to 20 years, sometimes less in harsh environments. Over the past few decades, several major pump manufacturers have ceased trading or significantly retracted from certain geographies, and so like-for-like replacement isn’t always possible leaving operators having to replace failing pumps with ones from a different manufacturer. This can entail a significant risk in matching the new pump to an existing pump’s specification (which has sometimes been lost from the company) and the possibility of extensive downtime as pipework, mountings and fittings are changed to suit the new pump.

Amarinth is being approached by an increasing number of organisations from industries as diverse as oil and gas, defence, food and drink, process plants and breweries looking for a solution to this growing problem of obsolete support and which can minimise risk, downtime and disruption. Amarinth has already developed a significant expertise and a growing business in manufacturing spares and re-engineering components for Girdlestone pumps, which ceased trading some 16 years ago, and can already provide plug-and-play new pumps to replace many of the Girdlestone range. However, Amarinth has listened carefully to those customers who want to keep their existing pumps and fully refurbish them to extend their service life and has launched this new strip, report and refurbishment service to meet their needs.

This service, which can be used for refurbishing most API 610 and ISO 5199 pumps, is delivered by trusted and reliable experts who offer best advice for the most cost-effective solution considering the specific needs of each customer. This starts with a detailed mechanical and hydraulic assessment to evaluate the viability of servicing a pump or determine if it would be more cost-effective to replace it. The assessment looks at the condition, working life and maintenance regime of the pump and the duties and requirements, such as the flow, head, power, NPSH and materials, in addition to the physical pipework, fittings and baseplates that may need alteration. By offering both the option of replacing the pump, sometimes with a plug-and-play solution, or refurbishing the pump with new, often improved components, Amarinth is ideally placed to offer the customer best advice.

If refurbishment is a viable option, then Amarinth has developed a standard procedure to make sure that all important components are replaced and knowledgeable engineers carefully inspect all non-replacement items for wear to ensure they are within tolerance. In some cases, using modern design and manufacturing tools alongside the skills of its own pump design engineers, Amarinth is able to re-engineer components, rather than just replicate them, improving on the original design and increasing the pump’s reliability or performance. The company can even design and manufacture whole new interchangeable sub-assemblies to resolve outstanding issues operators are experiencing with their existing pumps.

Following the extensive overhaul, pumps are tested at Amarinth’s in-house facility to certify them to the same standards as a new pump, giving customers peace of mind that the refurbished pumps will operate reliably for a further 20 years. Customers also benefit from long-term support from Amarinth and a readily available supply of spares.

Oliver Brigginshaw, Managing Director of Amarinth, comments, “We have launched this strip, report and refurbishment service to address a growing need for a cost-effective but low risk way for organisations to extend the life of industrial pumps without the need for wholesale replacement. As a pump design and manufacturing company we are able to draw on our broad range of skills and knowledge to ensure we return to our customers refurbished pumps that will often outperform their original specification with minimal disruption to their business and with on-going support well into the future.”
