The impeller cover of the Espa Niper pump is a plastic component that forms the front closure of the hydraulic section of the pump. Inside the cover is the inlet opening for the supply of water to the impeller.
A cracked or deformed cover causes water seepage, a drop in flow and cavitation of the pump. Replacing the cover with an original part restores the tightness of the hydraulics and the full performance of the pump.
The original Espa cover is precisely shaped for the Niper model and compatible with standard seals. When replacing the cover, we also recommend replacing the impeller cover seal to ensure long-term tightness.
