The Wacker Neuson Water Pump Impeller is a genuine OEM component designed for the MDP3 series trash pumps, including the MDP3 Trash Pump models. As a direct OEM replacement sourced from Wacker Neuson, part is manufactured to the same standards as the original, ensuring correct fit and function within the pump assembly. This impeller is the right choice for operators looking to restore full pumping capacity on their MDP3 equipment using an authorized replacement part.
Key Features
- OEM-Grade Impeller Construction — Manufactured to original Wacker Neuson specifications, delivering the blade geometry and material integrity needed to sustain consistent water flow and pressure output.
- Drop-In Replacement for MDP3 Series — Engineered to mount directly onto the MDP3 pump shaft and housing, aligning with existing ports and fastener locations for a straightforward swap.
- MDP3 Series Compatibility — Verified fitment across multiple MDP3 trash pump configurations, including standard and dimensioned variants (L593, W440, H442).
- Restore Full Pump Performance — A worn or damaged impeller causes loss of prime, reduced flow rate, and overworking of the engine; replacing it with 5000404462 brings pumping output back to original capacity.
- Genuine Wacker Neuson Part — Backed by Wacker Neuson's OEM supply chain, so you can be confident the part leaving the box is the exact component the machine was built around.
The water pump impeller is the rotating core of the pump assembly — its spinning vanes create the centrifugal force that draws water in through the inlet and pushes it out through the discharge port. On a trash pump like the MDP3, the impeller must handle debris-laden water without losing efficiency, making material quality and dimensional accuracy critical. When the impeller wears, cracks, or becomes damaged, flow rate drops noticeably, the pump struggles to prime, and the engine can run hotter under the added load — all signs that the impeller needs immediate replacement.
