The Wacker Neuson Volute Insert Kit is a genuine OEM component designed for the PT2A, PT2B, and PTK2 50mm/2-inch centrifugal trash pumps. Sourced directly from Wacker Neuson, this kit ensures the volute chamber is restored to its original geometry and seal integrity — the same specification the pump was built with. It is compatible across the PT2A, PT2B, and PTK2 pump models, making it the go-to service kit for operators running any of these 2-inch units. Keeping the correct OEM part on hand means faster turnaround when a pump needs to get back on the job.
Key Features
- Genuine OEM Volute Fit: — Manufactured to the exact internal profile of the pump housing, ensuring the insert seats flush and maintains correct fluid passage geometry throughout the volute chamber.
- Drop-In Replacement for PT2-Series Pumps: — Designed to install directly into PT2A, PT2B, and PTK2 pump housings with no modification — the insert aligns to existing mounting points in the volute casing.
- Covers the Full PT2 Platform: — A single kit services the PT2A, PT2B, and PTK2 (engine-less) variants, so one part number covers your entire fleet of 50mm/2-inch centrifugal trash pumps.
- Restores Pump Efficiency: — A worn or damaged volute insert reduces discharge pressure and flow rate. Replacing it brings the pump back to its rated output, keeping water, slurry, and debris moving at the intended volume.
- Fuel and Fluid Path Integrity: — As an OEM kit, the insert materials and tolerances are validated for continuous contact with the fluids and debris these pumps handle — no guesswork on compatibility.
The volute is the spiral-shaped housing that surrounds the pump impeller and converts the high-velocity fluid coming off the impeller into pressure, directing it toward the discharge port. The volute insert lines the inner surface of this housing, and over time it can erode, crack, or lose its sealing interface due to abrasive slurries and hard debris passing through the pump. When the insert degrades, the pump loses efficiency — flow rate drops, discharge pressure falls off, and the machine has to work harder to move the same volume. Replacing the volute insert with the correct OEM kit restores the hydraulic path to its original condition and gets the pump performing at full capacity again.
