Wacker Neuson 5200023189 Volute — Genuine OEM Submersible Pump Replacement

The Wacker Neuson Volute is a genuine OEM component designed for the PS4-11003HH and PS4-1003HF series 100mm/4-inch submersible pumps. Sourced directly from Wacker Neuson, this part meets the same manufacturing standards as the original, ensuring the pump housing geometry is exactly right for consistent water flow performance. It is confirmed compatible across multiple PS4-series configurations including 220V, 440V, and 400V variants operating at both 50Hz and 60Hz.

Key Features

• OEM-Matched Flow Path Geometry — Cast and dimensioned to the original volute profile, preserving the hydraulic efficiency the pump was engineered to deliver.
• Direct Drop-In Replacement — Mounts to the PS4-series pump housing using the original bolt pattern, requiring no machining or adaptation to seat correctly.
• Broad PS4-Series Compatibility — Fits PS4-11003HH and PS4-1003HF submersible pumps across multiple voltage and frequency configurations, including 220V/60Hz, 440V/60Hz, and 400V/50Hz models.
• Restores Full Pump Output — A cracked or worn volute disrupts the pressure envelope around the impeller, causing flow loss and cavitation; replacing it with part 5200023189 restores rated head and output capacity.
• Genuine Wacker Neuson Part — Supplied as an authorized OEM component with the correct part number traceability, giving you confidence the part matches your machine's original specification.

The volute is the stationary spiral casing that surrounds the impeller inside a centrifugal pump. As the impeller spins, water is flung outward into the volute's expanding chamber, which converts velocity into pressure and directs flow toward the pump outlet. When the volute is cracked, eroded, or damaged, this pressure conversion becomes inefficient — the pump may run but deliver significantly reduced flow and head height. Replacing the volute with a correctly profiled OEM part is essential to restoring the pump's rated performance on dewatering and bypass applications.
