RMI’s intensive testing supports high-pressure pump safety, quality globally

A ccording to Kathryn Poke, director of engineer ing at RMI Pressure Systems, dedicated test cells in the company’s Manchester production facility support a range of technical tests to ensure final product quality. RMI Pressure Systems is a leader in high pressure and high-volume fluid pumping stations, with over a century’s experience in designing, manufacturing and supporting this tech nology. With a primary manufacturing facility in the UK, the company has operations in China, the US, India and Australia – supporting equipment in coun tries around the globe. Poke said that RMI Pressure Systems’ quality and testing regime means new equipment and compo nents can be put through as much as two million pump cycles – over periods of up to 160 hours – to prove their integrity. “In robust and continuous applications such as longwall coal mining, our customers rely on our high pressure reciprocating pumps to deliver opti mal uptime and safety,” she said. “Similarly, our steel industry customers look for quality and reliability in de-scaling and forging applications.” In these demanding and often hazardous envi ronments, pump pressures can reach 350 to 400 bar – making any leaks or defects potentially disastrous. She highlighted that RMI Pressure Systems’ meticu lous testing regime has been critical in building the company’s quality reputation for over a century. “Before delivery, all our equipment is put through its paces in our test cells,” she explained. “These well-resourced facilities measure and record tem peratures, pressures, speeds and other indicators – generating data that is carefully reviewed and analysed by our engineering team.” She emphasised that the test cells run alongside the company’s manufacturing processes, which are accredited in terms of ISO9001 quality standards. This ensures that the extended periods of testing do not compromise RMI’s production rates. The test facility can accommodate three RMI high pressure pumps at a time. “This means that our customers are confident that RMI equipment is ready to go when it is installed and commissioned on site,” said Poke. “There is no run-in time or bedding down to be done, so the Mines and industry rely on critical high pressure pump technology to keep opera tions safe and efficient, which makes rigorous testing of this equipment an es sential part of the manufacturing process.

pumps’ contribution to productivity and uptime will be immediate.” Experts from RMI Pressure Systems are avail able to assist with installing and commissioning the equipment, giving customers peace of mind, and ensuring optimal performance. The company’s manufacturing quality is also enhanced by its care ful selection of suppliers and components; these are chosen for their excellence, and regular quality assurance processes are applied. Cycle testing of components is also conducted to ensure a quality finished product. “Our inspection team tests new components extensively against the conformance criteria before giving it the thumbs up,” she said. “Staying up to date with technology allows us to improve designs, soft ware and materials of construction wherever possible; each improvement, though, needs to be thoroughly tested before we introduce it to the market.” 
