The impeller for ESPA Silen 150M and Silen S 150M pumps is a higher-performance variant of the rotating hydraulic component, designed for 1.5 HP class models with a higher flow than the 100M model.
A larger diameter or greater blade height delivers a flow–pressure characteristic matching the 150M performance class, which is suitable for medium-sized pools.
Wear of this component causes the flow to drop below the recommended filtration operating values, leading to a deterioration in water quality.
Replacement with the original part is a straightforward service task that requires neither special tools nor calibration after installation.
The shared part for the Silen 150M and Silen S 150M models reduces the number of spare part types that need to be kept in the service stock.
