The Wacker Neuson is a genuine OEM Volute designed for the PS4-11003HH and PS4-1003HF series submersible pumps. As a direct factory replacement, this volute restores the precise internal geometry the pump depends on to develop pressure and move water efficiently across the full range of voltage configurations — including 220V, 440V, 575V, and 400V/50Hz variants. Wacker Neuson genuine OEM parts are manufactured to the same specifications as the original components, ensuring a correct fit within the pump housing without modification. If your PS4 series submersible pump is showing reduced output, cavitation, or visible housing damage, part is the authorized replacement to bring it back to full operating condition.
Key Features
- Precision-Formed Flow Path: — The volute's internal spiral chamber is dimensioned to match the original, maintaining correct hydraulic velocity and pressure conversion across the impeller discharge.
- Genuine OEM Source: — Manufactured by Wacker Neuson to the same material and dimensional standards as the part it replaces — not an approximation.
- Broad PS4 Series Coverage: — Fits PS4-11003HH High Head and PS4-1003HF High Output submersible pump units across multiple voltage configurations (220V, 440V, 575V/60Hz and 400V/50Hz).
- Restores Rated Pump Output: — A damaged or worn volute causes pressure loss and reduced flow; replacing it with 5000150822 restores the pump's rated discharge performance.
- Direct Housing Replacement: — Engineered to align with the existing pump casing and impeller assembly, allowing straightforward disassembly and reinstallation in the field.
The volute is the stationary spiral-shaped casing that surrounds the pump impeller. As the impeller spins and accelerates water outward, the volute's gradually expanding chamber converts that kinetic energy into pressure, directing flow toward the discharge outlet. This conversion is what gives the pump its ability to lift water against head pressure or deliver high-volume output depending on the pump configuration. When a volute cracks, erodes, or becomes damaged — often from abrasive solids or impact — the pump loses its ability to build pressure efficiently, resulting in reduced flow rates, increased energy draw, and potential motor strain. Replacing the volute with a correctly dimensioned OEM part is essential to restoring the hydraulic integrity of the pump.
