The Wacker Neuson Impeller is a genuine OEM component designed for the PS4 7503HH, PS4 11003HH, PS4 7503HF, and PS4 11003HF series submersible pumps. As a factory-sourced part, it is manufactured to the exact tolerances required for proper hydraulic performance inside the pump volute. This impeller is compatible across multiple voltage configurations — 220V, 440V, and 575V variants — making it the correct replacement for a wide range of PS4-series units in the field. Confirm your machine's model number before ordering to ensure proper fitment.
Key Features
- Genuine OEM Hydraulic Precision — Manufactured to exact flow and clearance specifications for the PS4 pump housing, ensuring full rated output capacity is restored after replacement.
- Direct Drop-In Replacement — Matches the original impeller geometry and shaft interface, allowing installation without modification to the pump casing or volute.
- Broad PS4-Series Compatibility — Fits PS4 7503HH (10hp), PS4 11003HH (15hp), PS4 7503HF, and PS4 11003HF models across 220V, 440V, and 575V/60Hz configurations.
- Restore Full Pump Output — A worn or damaged impeller causes reduced flow rates, increased amp draw, and potential motor overload; replacing it returns the pump to rated performance.
- Electrical Safety Consideration — Correct impeller fit prevents internal imbalance that can stress the motor shaft and seals, protecting the submersible motor from moisture ingress and electrical failure.
The impeller is the rotating core of a centrifugal pump — it spins at high speed to accelerate water outward through the volute and toward the discharge port. In a submersible pump like the PS4 series, the impeller works in close proximity to the pump casing, so its geometry and surface condition directly determine how much flow the unit can deliver at a given head. When an impeller wears, erodes, or becomes damaged by debris, the pump loses efficiency rapidly: flow rates drop, the motor works harder to compensate, and run temperatures rise — all of which shorten service life significantly.
