The Wacker Neuson is a genuine OEM Washer M8 designed for the PS2 400, PS2 500, PSA2 500, and 50mm/2in submersible pump series. As a factory-sourced component, the matches the original specification exactly, ensuring a correct fit without guesswork or reworking. This washer is part of Wacker Neuson's submersible pump lineup, covering both standard and alternate-voltage configurations across the PS and PSA families. Keeping the correct hardware in place protects fastener clamp load and helps the pump assembly maintain its structural integrity through continuous operation.
Key Features
- Genuine OEM Hardware Grade — Sourced directly from Wacker Neuson, this M8 washer meets the exact material hardness and dimensional tolerancing specified for submersible pump assemblies.
- Direct-Fit Replacement — Engineered to seat flush against M8 fastener heads and mating surfaces in the pump housing, restoring the original clamp load without shimming or adjustment.
- Broad PS/PSA Series Coverage — Confirmed fitment across the PS2 400, PS2 500, PSA2 500, and 50mm/2in submersible pump models in both 110V/60Hz and 220V/60Hz configurations.
- Protects Fastener Integrity — A properly sized washer distributes clamping force evenly, preventing fastener pull-through and surface damage on pump housings exposed to continuous vibration and moisture.
- Corrosion-Resistant Construction — Built to withstand the wet, submerged operating environment typical of submersible pump applications, resisting surface degradation over extended service intervals.
A washer serves as a load-distributing interface between a fastener and the surface it bears against. In a submersible pump, where components are subjected to constant vibration, water exposure, and pressure cycling, correctly rated hardware is essential to keeping fastened joints secure and leak-free. When a washer wears thin, corrodes, or is omitted entirely, the fastener can loosen over time, leading to joint separation, misalignment of internal components, or housing damage that compromises pump performance.
