The Wacker Neuson Volute Insert Kit is a genuine OEM component designed for the PT2 series 50mm/2in centrifugal trash pumps, including the PT2Y, PT2A, PT2R, and PTK2 models. As a direct OEM replacement, this kit is manufactured to the exact tolerances and material specifications of the original part, ensuring a proper fit within the pump housing. Genuine Wacker Neuson parts like the are the straightforward choice when restoring pump performance to original operating condition. Confirm your model number before ordering to ensure compatibility with your specific PT2 series unit.
Key Features
- Genuine OEM Construction: — Manufactured to the original material and dimensional specifications for the volute insert, maintaining the precise flow geometry the pump was designed around.
- Drop-In Replacement: — Engineered to seat directly into the PT2 series pump housing the same way the original insert does, with no modifications to the housing or impeller assembly.
- Broad PT2 Series Compatibility: — Fits PT2Y, PT2A, PT2R, and PTK2 50mm/2in centrifugal trash pump models, including engine and non-engine configurations.
- Restores Hydraulic Efficiency: — A worn or damaged volute insert reduces pumping pressure and flow rate; replacing it with this kit brings discharge performance back to original levels.
- Fuel System and Wetted-Path Integrity: — The volute insert forms part of the water passage within the pump casing; using a correctly specified OEM insert protects against premature wear from abrasive slurry and debris typical of trash pump applications.
The volute insert sits inside the pump casing and forms the contoured channel that directs fluid from the spinning impeller outward toward the discharge port. This curved passage converts the velocity generated by the impeller into pressure, which is what actually moves water through the hose. When the insert is worn, cracked, or eroded — which is common in trash pump applications handling sandy or debris-laden water — the pump loses discharge pressure and flow rate noticeably drops. Replacing the insert with a correctly fitting kit restores the hydraulic path and brings the pump back to its rated output.
