The Multiquip 020CX400004 Impeller Nut is a genuine OEM component designed for CX400 submersible pumps. Sourced directly through Multiquip's authorized parts program, this nut is produced to the exact specifications required to retain the impeller securely within the pump assembly. Verified fitment for CX400 series equipment means you can order with confidence and get your pump back in service without second-guessing compatibility.
Key Features
- Genuine OEM Retention Integrity — Manufactured to the precise torque and thread specification required to hold the impeller firmly in place under continuous pump load, preventing slippage or loosening during operation.
- Direct-Fit Installation — Matches the original fastener thread pitch and seat profile of the CX400 pump shaft, allowing straightforward installation without modification to surrounding components.
- CX400 Series Compatibility — Confirmed fitment for Multiquip CX400 submersible pump equipment.
- Sustained Pump Output — A properly secured impeller nut keeps the impeller locked at the correct depth and alignment on the shaft, maintaining designed flow rate and pressure throughout the pump's operating cycle.
- Corrosion-Resistant Construction — Built to withstand the submerged, high-moisture environment of submersible pump service, where fastener degradation can accelerate rapidly with inferior hardware.
The impeller nut is the fastener that locks the impeller — the rotating component responsible for drawing water into the pump and pushing it through the discharge — firmly onto the motor shaft. If this nut loosens or fails, the impeller can shift axially on the shaft, causing a significant drop in flow performance, increased vibration, and potential damage to the pump housing or motor bearings. Replacing a worn or damaged impeller nut with the correct OEM part restores proper impeller seating and ensures the pump operates at its rated capacity.
