Pre-Filter Lid for SENA Pump

The pre-filter lid of the SENA pump is a transparent or solid plastic part that closes the pre-filter chamber, providing quick access to the basket for cleaning captured impurities without the need to disconnect the pump from the piping.

A cracked or leaking lid causes a pressure drop on the suction side of the pump, an increased risk of air bubbles in the system and reduced flow. Replacement with a genuine part reliably eliminates these problems.

The genuine lid guarantees the correct threading or bayonet fastening corresponding to the manufacturing specification of the SENA pump, so the lid fits perfectly and the gasket beneath it functions correctly.
