The impeller 100 24M is the hydraulic rotor of the single-phase Espa Silen S2 pump with a power of 1 kW (100). The number 24 indicates the diameter of the discharge port in millimetres, the designation M specifies a single-phase electrical supply.
In the event of cavitation, abrasion by sand or chemical attack on the plastic, the impeller may lose its original shape, which manifests itself as a drop in the flow rate and efficiency of the filtration system. The original replacement fully restores the performance parameters of the pump.
Replacement is accessible to a more skilled home DIY enthusiast as well as a service technician and significantly extends the operating life of the entire pump.
