PSH - Pre-filter Lid SM-044 with Cataphoresis Coating (FDN Series) - 2284401

PSH – Pre-filter Lid SM-044 with Cataphoresis Coating (FDN Series)

This is the genuine PSH replacement lid (cover) for the SM-044 cast iron pre-filter, designed for use with the PSH FDN series high-flow pool pumps (DN-1500 and DN-3000). The lid is finished with a cataphoresis electrochemical coating, which provides outstanding corrosion resistance and long service life even in demanding pool environments. It is sold individually and corresponds to position 51 on the official PSH FDN exploded-view diagram.

Compatibility

This lid fits the SM-044 pre-filter unit (models 325 to 326) paired with PSH FDN series pumps — including the FDN-1500-H, FDN-1500-V, FDN-1500-HV, and FDN-3000 — which are widely used in public swimming pools, competition pools, and water parks. Always cross-reference the exploded-view diagram (position 51) and your pump’s model number before ordering to confirm fitment.

Why Genuine Matters

The cataphoresis-treated cast iron construction is a hallmark of PSH’s FDN pre-filter range, delivering proven durability in chlorinated and saline pool water. A genuine PSH lid ensures the correct dimensional fit and sealing surface, preventing leaks and maintaining the hydraulic integrity of your filtration system. Aftermarket alternatives may not replicate the coating quality or precise tolerances required.

Installation

Fitting this lid is straightforward for a qualified pool technician: isolate and depressurise the pump, remove the old or damaged lid, inspect the sealing surfaces, and fit the new lid. We recommend replacing the pre-filter gasket or O-ring at the same time to ensure a leak-free seal. Professional installation is advised for commercial pool systems.
