The impeller is intended for ESPA Silen 75M and Silen S 75M pool pumps and ensures their nominal hydraulic performance as water flows through the filtration circuit.
The blade profile is optimised for the operating point of these models, which achieves maximum flow rate with minimal electrical energy consumption.
A damaged or eroded impeller manifests itself in a drop in flow rate and characteristic humming or vibration of the pump, which signal the need to replace the part.
Installation requires no special tools, and an experienced pool owner can manage it themselves after the standard shutdown and depressurisation of the system.
