The Wacker Neuson is a genuine OEM 10 X 8 X 22 Key designed for the PSC43703 and PSC43803EX submersible pumps. Sourced directly from Wacker Neuson, this key is manufactured to the exact dimensions and tolerances required by these machines. As a genuine OEM component, it ensures a direct, tool-free drop-in fit with no guesswork on sizing or compatibility. This part is confirmed for use across both the PSC43703 and PSC43803EX submersible pump models.
Key Features
- Exact OEM Dimensions — Manufactured to the precise 10 x 8 x 22 mm specification required for correct shaft-to-hub engagement in these pump models.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, ensuring material grade and dimensional accuracy consistent with the original component.
- Confirmed Fitment — Compatible with PSC43703 and PSC43803EX submersible pumps; verify your model before ordering.
- Secure Power Transfer — A correctly sized key locks the impeller or drive shaft in place, ensuring torque is transmitted without slippage or play.
- Straightforward Installation — Slides directly into the keyway slot on the shaft and hub, requiring no machining or modification to fit.
A shaft key is a small but critical component that locks a rotating element — such as an impeller or coupling — to a drive shaft, ensuring that torque is transferred without slippage between the two parts. In a submersible pump, this means the impeller spins at the correct speed relative to the motor shaft, maintaining pumping efficiency and flow rate. When a key shears, wears, or goes missing, the shaft and impeller spin independently, causing the pump to lose output entirely or run unloaded — which can quickly damage the motor or seal assembly.
