The Wacker Neuson Impeller is a genuine OEM component designed for PT3A and PT3A(I) series self-priming centrifugal trash pumps. As a direct OEM replacement, this impeller is manufactured to the same specifications as the original part, ensuring consistent hydraulic performance and proper fit within the pump volute. Compatible with both the PT3A and PT3A(I) models, this is the correct part to specify when restoring pump output on these 3-inch discharge trash pumps. Keep a spare on hand to stay ahead of unplanned pump service on demanding dewatering and fluid transfer applications.
Key Features
- OEM Hydraulic Profile: — Cast to the original impeller geometry, maintaining rated flow rate and discharge pressure specific to the PT3A pump family.
- Drop-In Fitment: — Mounts directly to the pump shaft and seats within the volute housing without modification, matching original bolt pattern and clearance tolerances.
- Verified Compatibility: — Confirmed fit for PT3A and PT3A(I) series 3-inch self-priming centrifugal trash pumps.
- Restored Pump Performance: — A worn or damaged impeller causes a measurable drop in flow volume and prime speed; replacing with this OEM part brings output back to full rated capacity.
- Genuine Wacker Neuson Part: — Sourced directly through the Wacker Neuson OEM supply chain, so you receive the exact component the machine was built around — not an approximation.
The impeller is the rotating core of a centrifugal trash pump — it spins at high speed to draw fluid into the pump housing and accelerate it toward the discharge port. In trash pump applications, the impeller must handle abrasive slurry, sediment, and soft solids without losing its hydraulic efficiency. When an impeller wears, erodes, or becomes damaged, the pump loses prime more slowly, flow rate drops, and the engine loads unevenly. Replacing the impeller with the correct OEM part — Wacker Neuson 5100044387 — restores the pump's ability to move the volumes of water and debris these machines are rated to handle on active dewatering and site drainage jobs.
