The Wacker Neuson Impeller is a genuine OEM component designed for the PS4 11003HH and PS4 11003HF series submersible pumps. As a direct factory replacement, this impeller restores the pump's original hydraulic output across the full range of supported voltage configurations, including 220V, 440V, and 575V models. Wacker Neuson sources this part to the same specifications as the original, ensuring a correct fit within the pump casing without any adaptation. If you're working with a PS4 11003HH or PS4 11003HF and need to bring flow performance back to spec, part is the correct replacement.
Key Features
- Genuine OEM Hydraulic Geometry — Manufactured to Wacker Neuson's original impeller profile, preserving the designed flow rate and pressure output of the PS4 series pump.
- Drop-In Replacement for PS4 Series Pumps — Engineered to seat correctly within the PS4 pump casing and interface with the existing shaft and wear ring, matching the original assembly configuration.
- Broad Voltage Compatibility — Fits PS4 11003HH units in 220V and 440V configurations and PS4 11003HF units running on 220V, 440V, and 575V, covering the full high-output submersible lineup.
- Restores Full Pumping Capacity — A worn or damaged impeller causes significant drop in flow volume and discharge pressure; replacing it with 5000150823 brings the pump back to its rated output.
- Verified OEM Part Number — Sourced directly through Wacker Neuson's parts program, so you can order with confidence that 5000150823 is the correct, current part for these machines.
The impeller is the rotating core of a centrifugal pump — it spins at high speed to draw water in through the pump inlet and accelerate it outward, generating the flow and pressure that moves water through the discharge line. In a submersible pump like the PS4 series, the impeller operates fully submerged and must maintain precise clearances with the pump casing to deliver rated performance. When the impeller becomes eroded, cracked, or worn from abrasive debris, the pump loses flow capacity, draws more current, and can overheat — replacing it promptly protects the motor and restores output to the level the machine was built to deliver.
