Confirm your model number before ordering to ensure the correct fit for your specific pump configuration.
Key Features
- Genuine OEM Construction — Manufactured to the original dimensional and material specification, ensuring the ring seats and retains correctly within the pump housing without rework.
- Broad PS Series Compatibility — Fits PS2-3703, PS3-3703, and PS4-3703 pump models across multiple voltage and frequency configurations, plus PSC series submersible pumps.
- Secure Retention Function — Maintains the mechanical integrity of the pump assembly by locking internal components in position during continuous submersed operation.
- Multi-Voltage Coverage — Verified fitment across 220V, 440V, 575V, and 400V pump builds in both 50Hz and 60Hz variants — one part number spanning the full PS3703 voltage range.
- Direct OEM Replacement — Drops into place exactly as the original, with no machining or modification needed to restore the pump to operational condition.
A locking ring in a submersible pump is a retaining component that secures key internal assemblies — such as the motor housing, impeller stack, or seal cartridge — within the pump body, preventing movement or separation during operation. In a submersible pump, where the entire unit operates under continuous water pressure and vibration, a correctly seated locking ring is essential to maintaining pump integrity and preventing water ingress into the motor cavity. When a locking ring becomes damaged, corroded, or fails to seat properly, it can allow internal components to shift, leading to vibration, reduced pumping efficiency, seal failure, or motor damage.
