Multiquip 1129221010 Pump Shaft - OEM Replacement Part

The pump shaft is a critical rotating component that transfers power from the engine to the impeller assembly in centrifugal water pumps, enabling the centrifugal force needed to move water through the suction line and expel it from the discharge ports. This genuine OEM shaft maintains the precise tolerances required for proper impeller/volute assembly operation in high-performance dewatering applications.

The QP15HP pump is designed for clear water applications with limited solid handling capability of only 10% by volume, capable of suction lifts up to 25 feet at sea level. The shaft works within a wet primed centrifugal pump system that creates a partial vacuum, allowing reduced atmospheric pressure to flow water through the suction line. During vacuum testing, a properly functioning pump system should achieve readings between -25 and -20 in. Hg (inches of mercury), which translates to 25 feet of lift at sea level. Shaft failure symptoms may include reduced vacuum performance, abnormal vibration, or complete loss of pumping capability.

This shaft is engineered to withstand the demanding conditions of general purpose dewatering in agricultural, industrial, and residential applications while maintaining optimal performance across various elevations.

Compatible with the following Multiquip models:

• QP15HP
