The Multiquip 1471040031ASSY Impeller Assembly is a genuine OEM component designed for QP4TZ, QP4TKT, and QP4TK series trash pumps. Sourced directly from Multiquip, this assembly matches the original specification and installs as a direct drop-in replacement within the pump volute housing. Correct fitment is confirmed for the QP4TZ, QP4TKT, and QP4TK models — verify your model code before ordering to ensure compatibility. As a genuine OEM part, the 1471040031ASSY delivers the same hydraulic performance and dimensional accuracy as the original unit that shipped with your machine.
Key Features
- Genuine OEM Hydraulic Geometry — Engineered to the original blade pitch and diameter spec, maintaining rated flow and head pressure output on your trash pump.
- Direct-Fit Replacement — Mounts directly into the pump casing on QP4TZ, QP4TKT, and QP4TK models with no machining or modification to the volute or shaft interface.
- Confirmed Fitment — Verified for QP4TZ, QP4TKT, and QP4TK Multiquip trash pump models; always cross-reference your model code before ordering.
- Sustained Pumping Capacity — A worn or damaged impeller causes a noticeable drop in flow rate and suction lift; this assembly restores full pumping performance and priming ability.
- Trash-Handling Durability — Built to handle the abrasive slurries, solids, and debris typical of trash pump applications without accelerated wear to vane edges.
The impeller is the rotating core of a centrifugal trash pump — it spins at high speed to generate the centrifugal force that draws fluid into the pump inlet and pushes it out through the discharge port. In a trash pump, the impeller must also pass solids and semi-solid debris without clogging or fouling, making the geometry and material of the vanes critical to performance. When an impeller wears, chips, or becomes imbalanced, the pump loses suction, flow rate drops off, and the unit may struggle to prime — replacing it promptly with the correct OEM assembly restores the pump to full working capacity.
