The Wacker Neuson Impeller is a genuine OEM component designed for the PS4-series submersible pumps, including the PS4 3703, PS4 7503HH, PS4 7503HF, PS4 11003HH, and PS4 11003HF models across 220V, 440V, and 575V configurations. As a direct OEM replacement, the is manufactured to the same specifications as the original part, ensuring correct hydraulic clearances and balanced rotation within the pump housing. Verify your machine model and voltage rating against the fitment list before ordering to confirm compatibility with your specific unit.
Key Features
- OEM Hydraulic Geometry: — Cast and finished to the same flow-path dimensions as the original, maintaining the pump's rated discharge volume and head pressure across all covered voltage variants.
- Drop-In PS4-Series Fitment: — Engineered to mount directly onto the PS4-series motor shaft and seat correctly within the existing volute housing, with no machining or adaptation required.
- Broad Voltage Coverage: — A single part number covers PS4 submersible pump units configured for 220V/60Hz, 440V/60Hz, and 575V/60Hz operation, simplifying parts sourcing across your fleet.
- Sustained Pumping Performance: — A worn or eroded impeller causes a sharp drop in flow rate and pressure; replacing it with a correctly profiled OEM impeller restores the pump's full dewatering capacity.
- Corrosion-Resistant Construction: — Built to withstand continuous immersion in the abrasive, debris-laden water conditions that PS4-series submersible pumps are routinely deployed in on construction sites.
The impeller is the rotating core of a centrifugal pump — it draws water in through the pump inlet and accelerates it outward using centrifugal force, converting motor speed into flow and pressure. In Wacker Neuson PS4-series submersible pumps, the impeller works inside a sealed volute housing to move high volumes of water efficiently from sumps, excavations, and flooded areas. When the impeller wears, chips, or becomes clogged, flow rate and lift capacity drop noticeably, and the motor may begin to overheat from increased load — making timely replacement critical to keeping the pump operating at its rated output.
