The Wacker Neuson Volute is a genuine OEM component designed for the PT3, PT3A, PT3H, and PT3V series 75mm/3-inch centrifugal trash pumps. As a direct factory replacement, this volute restores proper hydraulic flow geometry inside the pump housing, ensuring consistent discharge performance on the jobsite. It is verified to fit across the full PT3 pump family, covering multiple configurations and build revisions. Keep your pump running at rated capacity with the correct OEM part rather than risking performance loss with an ill-fitting substitute.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to Wacker Neuson's original flow-path geometry, ensuring the volute channel maintains correct water velocity and discharge pressure specific to 3-inch trash pump design.
- Direct Housing Match — Engineered to seat flush within the PT3 pump casing with correct bolt-pattern alignment, allowing a straightforward swap without machining or shimming.
- Broad PT3 Family Coverage — Fits PT3, PT3A, PT3H, and PT3V models across numerous serial configurations, making this a single-part solution for mixed PT3 fleets.
- Sustained Discharge Performance — A correctly fitted volute maintains rated flow output; a cracked or worn volute causes pressure drop, cavitation, and reduced pumping capacity on dewatering and slurry applications.
- OEM Part Number Confidence — Part number 5000117808 is the factory-assigned reference, eliminating guesswork when cross-referencing against service manuals or machine serial records.
The volute is the curved, snail-shaped housing that surrounds the pump impeller inside a centrifugal trash pump. As the impeller spins, the volute collects the high-velocity water thrown outward by the impeller blades and gradually converts that velocity into pressure, directing flow toward the discharge port. Without a correctly shaped volute, the pump loses hydraulic efficiency — symptoms include reduced flow rate, excessive noise, and in severe cases, the pump losing its prime entirely. On demanding dewatering, bypass pumping, or trash-handling jobs, a damaged or incorrectly fitted volute can bring an entire operation to a halt.
