PSH - Pre-filter Lid SM-415 with Cataphoresis Finish – FDN Series - 3285101

PSH – Pre-filter Lid SM-415 with Cataphoresis Finish – FDN Series

This is the genuine PSH replacement lid for the SM-415 pre-filter, designed for use on PSH FDN series pool pumps (FDN-1500 and FDN-3000 variants). It covers and seals the pre-filter housing, allowing safe inspection and cleaning of the basket while keeping the pump system pressure-tight during operation. The cast-iron body is treated with a cataphoresis (electrocoat) finish for outstanding corrosion resistance in demanding pool environments.

Compatibility

This lid is a direct OEM replacement for position 51 on the PSH FDN Series exploded-view diagram, covering the full SERIE FDN pump range — including FDN-1500-H, FDN-1500-HV, FDN-1500-V, FDN-3000, and their bronze variants. Always cross-reference your pump’s exploded-view diagram (positions 135–136) before ordering to confirm fitment.

Why Genuine Matters

PSH’s cataphoresis-treated cast-iron components are engineered to withstand continuous exposure to chlorinated water, saltwater, and the mechanical stresses of high-flow commercial pool systems. A genuine PSH lid ensures a precise dimensional match to the pre-filter housing, preventing leaks and pressure loss that poorly fitting aftermarket parts can cause. Using an OEM part also keeps your pump’s warranty and service record intact.

Installation

The SM-415 lid is designed for straightforward removal and refitting during routine pre-filter basket maintenance. Always depressurise the pump system fully before opening the pre-filter housing. It is recommended that installation or replacement is carried out by a qualified pool technician, particularly on commercial or high-flow installations.
