The Wacker Neuson Plain Washer M12 is a genuine OEM hardware component designed for PS2, PS3, and PS4 series submersible pumps. Sourced directly from Wacker Neuson, this washer meets the exact material and dimensional specifications of the original part installed at the factory. Confirmed fitment spans a wide range of PS series models, including the PS2-1503L, PSA2-1503L, PS2-2203L, PSA2-2203L, PS3 1500, PS3 2200, PS4-1003HF, and PS4 11003HH variants. Ordering by part number ensures you receive the correct washer for your specific pump configuration.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Wacker Neuson's original dimensional and material specifications, ensuring correct load distribution and clamping force for M12 fastener assemblies in pump applications.
- Direct Drop-In Fit — Sized and profiled to seat correctly on M12 fastener positions as originally assembled, requiring no modification to hardware or mating surfaces.
- Broad PS Series Compatibility — Fits PS2, PSA2, PS3, and PS4 submersible pump families, including single-phase and three-phase variants across multiple voltage configurations.
- Protects Fastened Surfaces — Distributes clamp load evenly across pump housing and component mating surfaces, preventing damage from fastener pull-through or surface deformation during assembly and service.
- Essential for Correct Reassembly — Replacing worn or missing washers during pump service maintains proper torque retention and prevents fastener loosening under the continuous vibration loads typical in submersible pump operation.
A plain washer serves as a load-spreading interface between a fastener — such as a bolt or nut — and the surface it clamps against. In submersible pump assemblies, where components are subjected to moisture, vibration, and repeated service cycles, a correctly specified washer prevents the fastener from cutting into or deforming the housing material, which can compromise the integrity of the joint over time. Without a properly seated washer, fasteners may loosen prematurely or cause surface damage that makes future servicing more difficult.
