The Wacker Neuson is a genuine OEM Locking Ring designed for PS3-5503 and PS4-5503 series submersible pumps. As a direct factory replacement, part is manufactured to the same specifications as the original component, ensuring a correct fit within the pump assembly. This Locking Ring is compatible across the full PS3-5503 and PS4-5503 lineup, covering 220V, 440V, 575V, and 400V/50Hz configurations in both 75mm/3-inch and 100mm/4-inch discharge sizes. Keeping this component in sound condition is essential to maintaining the structural integrity of the pump and preventing unplanned service interruptions.
Key Features
- Genuine OEM Construction: — Manufactured to the original retention tolerances required to hold pump internals securely under continuous submersed operation.
- Direct-Fit Replacement: — Seats and locks into the existing pump housing exactly as the original, with no rework or adaptation to the surrounding components.
- Broad PS-Series Compatibility: — Fits the full PS3-5503 and PS4-5503 submersible pump range across 220V, 440V, 575V, and 400V/50Hz electrical configurations.
- Structural Retention Under Load: — Maintains correct alignment and axial positioning of internal pump components during continuous high-volume pumping cycles.
- Verified OEM Part Number: — Supplied under Wacker Neuson part number 5000150798, eliminating guesswork when ordering for multiple machine numbers within the PS-5503 family.
A locking ring secures and retains internal components within the pump housing, preventing axial movement of the impeller or motor shaft assembly during operation. In a submersible pump like the PS3-5503 and PS4-5503, where the unit runs fully submerged and under continuous hydraulic load, this retention is critical to maintaining pump output and protecting surrounding seals and bearings. When a locking ring becomes worn, corroded, or fails entirely, internal components can shift, leading to vibration, reduced pumping efficiency, accelerated wear on adjacent parts, and potential motor damage.
