PSH - Replacement Motor for ND.1-28M / ND.2-28M Pool Pump (2 HP) - 450122000

PSH – Replacement Motor for ND.1-28M / ND.2-28M Pool Pump (2 HP)

This is the genuine PSH replacement motor unit for the ND.1-28M and ND.2-28M single-phase pool pumps, referenced as position 300 in the official PSH exploded-view diagram. Rated at 2 HP and running at 3,000 RPM, it is the heart of the ND pump series and restores full pumping performance when the original motor fails or degrades. It is supplied as a single unit, purpose-built to fit directly into the existing pump body without modification.

Compatibility

This motor is compatible with both the PSH ND.1-28M and PSH ND.2-28M pump models. The ND.2 was designed as a direct successor to the ND.1, with identical mounting dimensions, making this motor a cross-compatible spare for both generations. Always verify your pump’s model and manufacture date against the exploded-view diagram (position 300) before ordering, and consult a technician if your pump pre-dates 2015.

Why Genuine Matters

As an original PSH spare part, this motor is manufactured to the same specifications as the unit fitted at the factory — including IP55 ingress protection, Class F insulation, and single-phase 230 V wiring. Using a genuine replacement ensures correct electrical ratings, safe operation, and preserves any remaining warranty on your pump installation. Aftermarket alternatives may not match the thermal protection or shaft dimensions of the original.

Installation

Motor replacement on the PSH ND series is a task that requires disconnecting mains power, draining the pump, and correctly re-seating the mechanical seal and shaft alignment. Professional installation by a qualified pool technician or electrician is strongly recommended to ensure safe commissioning and to avoid damage to ancillary components such as the impeller or mechanical seal.
