The Wacker Neuson Volute is a genuine OEM component designed for the PT2, PT2A, PT2H, and PT2V series 2-inch self-priming centrifugal trash pumps. As a direct factory replacement, this volute restores proper hydraulic flow characteristics to keep your pump moving water efficiently on the jobsite. Wacker Neuson genuine OEM parts are manufactured to the same specifications as the original, ensuring a correct, confident fit every time. Compatible across multiple PT2-family configurations including the PT2A, PT2H, and PT2V variants, part number covers a wide range of 50mm/2-inch pump builds.
Key Features
- Genuine OEM Hydraulic Integrity — Cast to the same internal geometry as the original, preserving the pump's designed flow path and pressure recovery characteristics.
- Direct Bolt-On Replacement — Matches original mounting points and port dimensions on PT2-series pump housings for a straightforward swap with no rework.
- Broad PT2-Family Fitment — Verified compatible with PT2, PT2A, PT2H, and PT2V models across multiple machine numbers in the 50mm/2-inch centrifugal trash pump lineup.
- Restores Full Pumping Performance — A cracked or worn volute causes pressure loss and reduced flow output; replacing it with 5000119779 brings discharge capacity back to spec.
- Long-Term Wear Resistance — Manufactured from materials selected to handle abrasive slurry, solids-laden water, and the continuous high-velocity flow typical of trash pump applications.
The volute is the stationary spiral-shaped casing that surrounds the pump's impeller. As the impeller spins and accelerates water outward, the volute's gradually widening channel converts that velocity into usable pressure, directing flow toward the discharge port. It is one of the primary components determining a pump's flow rate and discharge pressure. When a volute cracks, erodes, or becomes damaged, the pump loses the ability to build pressure efficiently, resulting in reduced output, longer fill times, and potential overloading of the engine. Replacing a failed volute with a correctly matched part is essential to restoring full pump performance.
