CRU PUMPS - S SERIES
Amarinth S 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. S Series CRU pumps are designed for low NPSH to reduce the overall CRU footprint and all have independently verified, full ATEX compliance.
The S Series general industrial pumps are designed to be fully interchangeable with a Girdlestone SSM or SSD pump. Amarinth’s S 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 S Series CRU pump will simply slot straight in to the space left by the original.

Problems with fractional motors?
We also have a conversion kit to adapt an old fractional motor pump to use a modern, more efficient lower cost metric motor, again without modifying pipework.
