The Wacker Neuson Volute Insert is a genuine OEM component designed for the PT2 series 50mm/2-inch self-priming centrifugal trash pumps, including the PT2, PT2A, PT2H, and PT2V models. As a direct OEM replacement, this part is manufactured to the same specifications as the original, ensuring it seats and seals correctly within the pump housing without any modification. Fitment covers a wide range of PT2-family configurations across multiple build variants, making this the right choice whether you're servicing a PT2A, PT2H, or PT2V unit. Keep a spare on hand to minimize unplanned pump downtime on demanding job sites.
Key Features
- Genuine OEM Construction: — Molded and dimensioned to original Wacker Neuson tolerances, ensuring correct fluid channeling and pressure containment within the pump volute chamber.
- Drop-In Replacement: — Designed to seat directly into the existing pump housing on PT2-series units, matching all mounting points and sealing surfaces of the original part.
- Broad PT2 Family Coverage: — Confirmed fitment across PT2, PT2A, PT2H, and PT2V pump variants, covering multiple machine numbers and production runs within the 50mm/2-inch trash pump line.
- Restores Peak Flow Performance: — A worn or cracked volute insert disrupts the spiral flow path that converts impeller energy into discharge pressure; replacing it restores rated flow and lift capacity.
- Verified Part Number: — Sourced and catalogued as Wacker Neuson part 5000119785, giving you confidence you're ordering the correct component for your specific pump model.
The volute insert is the shaped inner liner of the pump casing that surrounds the impeller and forms the spiral flow channel directing water from the impeller eye toward the discharge port. Its geometry is critical — the gradually widening spiral converts the high-velocity fluid leaving the impeller into usable pressure at the outlet. When the volute insert cracks, erodes, or becomes damaged by abrasive debris, the pump loses efficiency, output pressure drops, and flow rate falls below rated capacity. Replacing a damaged volute insert promptly restores the hydraulic performance the PT2-series pump was designed to deliver.
