The Wacker Neuson Spring Washer is a genuine OEM component designed for the PS2, PSA2, PST2, PST3, PSTF2, PSTF3, PSR1, PSG2, PSC3, and PSA2 series submersible pumps. As a direct OEM part sourced through authorized Wacker Neuson supply channels, the meets the exact material and dimensional specifications of the original component. This Spring Washer supports a wide range of pump configurations across multiple voltage ratings, including 110V and 230V variants, making it a versatile service item for fleets running mixed pump models. Confirm your model number against the fitment list before ordering to ensure a correct match.
Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to the original load and deflection spec, maintaining correct clamping force within the pump assembly rather than relying on a generically rated substitute.
- Drop-In Replacement — Matches the original bore diameter, outer diameter, and thickness so it seats correctly without modification to fastener stack-ups or mating surfaces.
- Broad Submersible Pump Compatibility — Fits PS2, PSA2, PST2, PST3, PSTF2, PSTF3, PSR1, PSG2, and PSC3 series Wacker Neuson submersible pumps across multiple voltage and cord configurations.
- Corrosion-Resistant Material Grade — Spring washers in submersible pump environments face continuous moisture exposure; the OEM-spec material resists corrosion and maintains elasticity under wet operating conditions.
- Prevents Fastener Loosening Under Vibration — A worn or flattened spring washer allows critical fasteners to back out during pump operation, leading to misalignment or seal failure; replacing it restores proper preload.
A spring washer is a small but mechanically critical fastener component placed beneath a nut or bolt head to maintain clamping tension in assemblies subject to vibration or thermal cycling. In a submersible pump, where the motor and impeller generate continuous vibration during operation, spring washers prevent fasteners from loosening over time — protecting internal seals, bearing housings, and motor mounts from the consequences of lost preload. When a spring washer flattens, cracks, or corrodes, it loses its ability to exert that retaining force, which can allow fasteners to work loose and lead to water ingress, vibration-induced wear, or catastrophic seal failure.
