The impeller cover seal is a key element of the hydraulic section of the ESPA IRIS, Silen I, and NOX pumps, which prevents water from leaking between the cover and the pump body.
Wear or damage to this seal manifests itself as water dripping from the pump and a drop in discharge pressure – symptoms that should not be ignored.
Timely replacement of the seal is many times cheaper than repairing the damage caused by operating the pump with a leak, or its complete replacement.
The original dimensions of the part guarantee a precise fit and reliable sealing without the need for further adjustments during installation.
