The Multiquip 1466040031 Impeller is a genuine OEM component designed for QP4TB and QP4TH quick-prime trash pumps. As a direct OEM replacement, it meets the original engineering specifications set for these pumps, ensuring the rotational hydraulics perform exactly as intended. This impeller is confirmed to fit the QP4TB and QP4TH models, making part selection straightforward for operators and service technicians keeping these machines in working condition.
Key Features
- Genuine OEM Construction: — Cast and balanced to the original Multiquip specification for the QP4TB and QP4TH, delivering the flow rates and lift capacity these pumps were designed to achieve.
- Drop-In Replacement: — Mounts directly to the pump volute using the original hardware configuration, requiring no machining or adaptation of the pump housing.
- Confirmed Fitment: — Verified for use on QP4TB and QP4TH quick-prime trash pump models.
- Restored Pumping Performance: — A worn or damaged impeller causes loss of prime, reduced flow, and excessive cavitation; replacing with 1466040031 restores rated discharge volume and suction lift.
- Trash-Duty Rated: — Designed to handle the abrasive slurries, suspended solids, and debris loads typical of trash pump applications on active jobsites.
The impeller is the rotating core of a centrifugal pump — it spins at high speed to draw fluid into the pump housing and accelerate it outward toward the discharge port. In a trash pump like the QP4TB and QP4TH, the impeller must handle water carrying solids, grit, and debris without losing efficiency. When an impeller wears down, becomes cracked, or chips from impact with debris, the pump loses prime easily, flow rate drops noticeably, and the engine may labor under the reduced hydraulic load. Replacing the impeller with the correct OEM part restores the pump to its rated performance and extends the service life of the surrounding pump components.
