PSH - Impeller for MAXI-40 Pool Pump (Pack of 3) - 3113710R

PSH – Impeller for MAXI-40 Pool Pump (Pack of 3)

This is the genuine PSH replacement impeller for the PSH MAXI 40 pool pump — the rotating hydraulic component responsible for drawing water through the pump and generating flow. A worn or damaged impeller directly reduces pump performance and flow rate, making timely replacement essential for maintaining a healthy pool circulation system. This listing supplies a pack of three impellers, ideal for service workshops or installers managing multiple units.

Compatibility

This impeller is designed exclusively for the PSH MAXI 40 pump (position 55 on the official PSH MAXI exploded-view diagram). The PSH MAXI series is a high-capacity, self-priming centrifugal pump engineered for medium to large residential and commercial swimming pools, as well as spa and wellness installations. Always cross-reference the exploded-view diagram and your pump’s model label before ordering to confirm fitment.

Why genuine matters

Genuine PSH impellers are manufactured to the precise hydraulic tolerances of the MAXI pump volute, ensuring optimal water flow, energy efficiency, and long service life. Aftermarket or incorrect impellers can cause vibration, reduced head pressure, premature seal wear, and may void any remaining pump warranty. Fitting an original PSH part guarantees the pump performs exactly as designed.

Installation

Impeller replacement requires draining and disassembling the pump wet end, including removal of the mechanical seal. Installation should be carried out by a qualified pool technician. Reference position 55 on the PSH MAXI exploded-view parts diagram to confirm correct orientation and torque requirements before reassembly.
