The Wacker Neuson Volute is a genuine OEM component designed for the PS2-3703, PS3-3703, and PS4-3703 series submersible pumps. As a direct OEM replacement, this volute is manufactured to the same specifications as the original part, ensuring a correct fit within the pump housing without the need for modification. This part covers a wide range of voltage configurations across the PS3703 pump family, including 50Hz and 60Hz models rated from 220V through 575V. If your submersible pump is losing discharge pressure or showing signs of wear in the pump casing, the Volute is the correct factory-sourced replacement to restore performance.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original casting and dimensional tolerances, ensuring the internal flow geometry matches the original volute exactly for proper hydraulic performance.
- Direct Replacement Fit — Designed to seat and seal within the PS3703 pump housing the same way as the factory part, with matching bolt patterns and discharge port alignment.
- Broad PS3703 Series Coverage — Compatible with PS2-3703, PS3-3703, and PS4-3703 submersible pumps across multiple voltage ratings, including 220V, 400V, 440V, and 575V models in both 50Hz and 60Hz configurations.
- Restored Pump Output — A correctly fitted volute maintains the designed flow velocity and discharge pressure; a cracked or worn volute causes pressure loss, reduced flow rate, and inefficient pumping.
- Verified Part Number — Cross-referenced directly to Wacker Neuson part 5000150466 for confidence in ordering the right component the first time.
The volute is the fixed, spiral-shaped casing that surrounds the pump's impeller. As the impeller spins, it accelerates water outward, and the volute's progressively expanding chamber converts that velocity into pressure, directing flow toward the discharge port. This conversion of kinetic energy into discharge pressure is what gives the pump its lift and flow capacity. When the volute is cracked, eroded, or damaged — often from abrasive solids in the water — flow efficiency drops noticeably, the pump works harder for less output, and in severe cases the pump may fail to prime or lose discharge head entirely.
