The Wacker Neuson Lock Washer is a genuine OEM component designed for the PS2, PS3, PS4, PSW, and PSC series submersible pumps. As a factory-sourced part, it meets the exact dimensional and material specifications set by Wacker Neuson for these pump families. This Lock Washer is confirmed to fit a wide range of submersible pump models, including PS2-1503, PS3-1503, PS2-2203, PS3-2203, PS4-11003HH, PS4-1003HF, PSW3-1500, PS2-1500, and multiple PSC-series units across various voltage configurations. Ordering the correct OEM part ensures proper fastener retention and long-term mechanical integrity in your pump assembly.
Key Features
- OEM-Grade Fastener Retention: — Manufactured to Wacker Neuson's exact material and dimensional spec, this Lock Washer delivers the correct clamping load and bite needed to prevent fastener loosening under vibration and continuous pump operation.
- Drop-In Installation: — Matches the original hardware profile exactly, seating directly into the existing fastener position without modification to mounting hardware or mating surfaces.
- Broad PS-Series Compatibility: — Fits PS2, PS3, PS4, PSW, and PSC submersible pump families across a wide range of voltage ratings, including 220V, 440V, 575V (60Hz), and 400V (50Hz) configurations.
- Prevents Fastener Backing Out: — A properly functioning lock washer holds critical pump components securely under sustained load; a worn or missing washer can allow fasteners to back out, leading to leaks, misalignment, or component failure.
- Genuine OEM Traceability: — Sourced directly through the Wacker Neuson parts supply chain under part number 5000150852, giving you full confidence in part authenticity and cross-reference accuracy.
A lock washer is a small but essential fastening component placed under a nut or bolt head to resist loosening caused by vibration, torque, and thermal cycling. In submersible pump assemblies — where motors run continuously and components are exposed to water pressure and electrical load — maintaining secure fastener engagement is critical to keeping seals tight and structural joints intact. When a lock washer wears flat or is omitted entirely, fasteners can gradually back out, compromising the pump's housing integrity and potentially allowing water ingress into the motor.
