Amarinth has delivered two vertical in-line pumps to EDF to replace obsolete pumps at the Sizewell B nuclear power station, Suffolk, United Kingdom. Replacement of obsolete equipment in power stations to maintain operations has become a major issue for power generation companies and so Roll-Royce has created the Proactive Obsolescence Management System (POMS) to quickly identify equipment suppliers that can provide replacement solutions for the obsolete equipment. Amarinth is registered in POMS and had previously undertaken a site survey of the existing pumps at Sizewell, giving EDF confidence that Amarinth fully understands the challenges of providing a replacement pump.
The new Amarinth vertical in-line super duplex pumps delivered to EDF are to replace existing but now obsolete filtration screen spray pumps for the drum screen wash process. The pumps are safe area rated, underwent a full suite of non-destructive evaluation (NDE), and carry 3.1 material certification for traceability. The pumps were also delivered to a tight 30-week deadline to coincide with a planned maintenance schedule thereby minimizing disruption at the power station.
