PSH - Pump Impeller for Micro-33 (Pack of 3) - 3111910R

PSH – Pump Impeller for Micro-33 (Pack of 3)

This is a genuine PSH replacement impeller for the PSH Micro-33 pool pump (0.33 HP). The impeller is the core rotating component that drives water circulation through your filtration system, and a worn or damaged one will cause a direct loss of flow and pressure. This listing supplies a pack of three impellers, making it ideal for workshop stock or scheduled maintenance programmes.

Compatibility

Designed exclusively for the PSH Micro series pump in the 0.33 HP variant. The PSH Micro is a self-priming centrifugal pump used in filtration systems for small, demountable, and spa-type pools. Always cross-reference the exploded-view diagram (position 55) and your pump model plate before ordering to confirm fitment.

Why Genuine Matters

PSH manufacture the Micro impeller from Noryl reinforced with 30% fibreglass — a material chosen for its dimensional stability, chemical resistance, and compatibility with both fresh water and saltwater/salt-chlorinator systems. An aftermarket substitute may differ in geometry or material, reducing efficiency and risking premature wear of the mechanical seal and diffuser.

Installation

Impeller replacement requires partial disassembly of the pump wet end, including removal of the pre-filter, pump body, and diffuser. Refer to the official PSH Micro exploded-view drawing and spare-parts list for correct reassembly sequence. Professional installation is recommended if you are not familiar with centrifugal pump servicing.
