The Multiquip 323FS0750N Shaft Rotor Without Bearing is a genuine OEM component designed for ST41230, ST41460, ST61230, and ST61460 submersible pumps. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring a proper fit within the pump assembly. This is a bare shaft and rotor assembly supplied without a bearing, making it the correct choice when replacing the rotating core while reusing or separately sourcing the bearing. Verify your model code before ordering to confirm compatibility with your specific submersible pump unit.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances for the rotor shaft, ensuring dimensional accuracy critical to proper pump rotation and hydraulic performance.
- Bare Shaft and Rotor Assembly — Supplied without a bearing, allowing targeted replacement of the shaft and rotor when the bearing is serviceable or sourced separately, reducing unnecessary part spend.
- Direct-Fit Replacement — Engineered to drop into the existing pump housing on compatible models with no machining or modification to the motor casing or impeller end.
- Broad Submersible Pump Compatibility — Fits ST41230, ST41460, ST61230, and ST61460 submersible transfer pump models, covering both the 4-inch and 6-inch frame sizes in this series.
- Restores Full Rotational Output — A worn or damaged shaft rotor causes vibration, reduced flow, and motor strain; replacing it with 323FS0750N returns the pump to its rated transfer capacity.
The shaft rotor is the central rotating component inside a submersible pump motor. It sits within the stator and converts electrical energy into mechanical rotation, which drives the impeller to move water. When the rotor shaft becomes worn, bent, or corroded — common in submersible applications where the unit operates fully submerged — the pump can lose efficiency, run rough, or fail to prime correctly. Replacing the shaft rotor assembly restores smooth rotation and protects the surrounding motor components from secondary wear caused by imbalance or misalignment.
