The Wacker Neuson 5000119403 is a genuine OEM Volute Insert designed for the PT3 series 75mm/3-inch self-priming centrifugal trash pumps, including the PT3, PT3A, PT3H, and PT3V models. As a direct OEM part, the part is manufactured to the exact dimensions and material specifications required by these pumps, ensuring a proper fit within the volute housing without modification. This part covers a wide range of PT3-series machine numbers, making it the correct choice for most configurations across this pump family. Keep a verified OEM replacement on hand to avoid extended downtime on time-sensitive dewatering or pump-out operations.
Key Features
- OEM-Matched Hydraulic Profile — Manufactured to the exact internal geometry of the original insert, preserving the designed flow path and pump efficiency across the PT3 series.
- Drop-In Replacement for PT3 Family Pumps — Fits directly into the volute housing on PT3, PT3A, PT3H, and PT3V models; no machining or shimming required.
- Broad PT3 Series Coverage — Verified fitment across multiple PT3, PT3A, PT3H, and PT3V machine configurations, covering both standard and tank-equipped variants.
- Maintains Pump Output Performance — A worn or eroded volute insert causes pressure loss and reduced flow rate; replacing it with the correct OEM part restores rated pump performance.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000119403 carries the same material and dimensional standards as the original production component.
The volute insert sits inside the pump's volute casing and forms the precision-shaped inner channel that converts the high-velocity fluid coming off the impeller into usable pressure and flow. Its curved internal profile is critical to how efficiently the pump moves water and entrained solids — even minor erosion or cracking of this insert disrupts the hydraulic balance and causes a measurable drop in discharge pressure and volume. On trash pump applications handling abrasive slurries or debris-laden water, the volute insert is a wear component that should be inspected regularly and replaced as soon as performance degradation is noticed.
