CRU PUMPS - U SERIES
Amarinth U Series CRU pumps are specifically designed and manufactured for condensate applications. The pumps are typically found in general industrial applications such a building services or hospitals. U Series CRU pumps are designed for low NPSH to reduce the overall CRU footprint and all have independently verified, full ATEX compliance.
The U Series CRU pumps are designed to be fully interchangeable with a Girdlestone URF or USM pump. Amarinth’s U Series CRU pump has identical termination points (i.e. suction & discharge flange positions) to the Girdlestone equivalent pump meaning there are no issues changing pipework when you replace your existing pump. The U Series CRU pump will simply slot straight in to the space left by the original.
