The pre-filter lid with a d38 spigot serves a dual function in the ESPA NIPER and NOX 25 pumps: it closes off the pre-filter basket compartment and at the same time serves as a connection point for a suction hose of 38 mm diameter.
The d38 spigot is a standard size compatible with most pool hoses, so the customer does not have to change the existing hose connection when replacing the part.
The transparent or white plastic design of the lid allows visual inspection of the basket condition without the need to dismantle it.
The original part fits precisely on the NIPER and NOX 25 pump body and guarantees proper sealing without the risk of air intake or water leakage.
