The impeller cover seal is a rubber sealing element placed between the impeller cover and the body of the Espa Niper or NOX 25 pump. It ensures the watertightness of the hydraulic part and prevents water seepage into the motor section.
Wear or deformation of the seal manifests itself as water dripping from the pump or a drop in pressure. Timely replacement of the seal prevents further damage to the pump and eliminates the need for a more expensive repair.
The original Espa elastomer seal is precisely dimensioned for the given model and ensures correct compression when the cover is tightened. Replacement is simple and can be managed by any more experienced pool owner with common tools.
