PSH - Diffuser Gasket for ND.1 & ND.2 Pool Pumps (Pack of 25) - 4050311R

PSH – Diffuser Gasket for ND.1 & ND.2 Pool Pumps (Pack of 25)

This is the genuine PSH replacement diffuser gasket (exploded-view position 60) designed to seal the diffuser assembly inside PSH ND.1 and ND.2 pool pumps. A sound diffuser gasket is critical for maintaining pump prime and hydraulic efficiency — a worn or damaged gasket allows air ingress, causing the pump to lose prime and underperform. Sold in a convenient trade pack of 25 pieces, this part is ideal for pool technicians and maintenance professionals servicing multiple units.

Compatibility

This gasket fits the PSH ND.1 and PSH ND.2 pool pump ranges. The ND.2 is the updated successor to the ND.1, sharing the same key dimensions, which is why a single gasket part covers both generations. Always cross-reference the exploded-view diagram (position 60) for your specific pump model before ordering. For pumps manufactured before 2015, verify compatibility with a qualified technician.

Why Genuine Matters

Genuine PSH spare parts are manufactured to exact OEM tolerances, ensuring a proper seal without adaptation or guesswork. Non-genuine gaskets may differ slightly in thickness or material, leading to premature failure, continued air leaks, or pump damage. Stocking genuine parts also reduces call-back visits and keeps your customers’ pools running reliably all season.

Installation

Replacing the diffuser gasket requires partial disassembly of the pump’s wet end. Isolate and de-energise the pump, drain the pump housing, and carefully remove the diffuser to access the old gasket. Clean the seating surface thoroughly before fitting the new gasket, and reassemble in reverse order. Professional installation is recommended to ensure correct torque and a leak-free result.
