The Wacker Neuson Plain Washer is a genuine OEM component designed for PS4-11003HH and PS4-11003HF series submersible pumps. As a direct factory replacement, this washer is sourced to the same specifications as the original hardware installed at the time of manufacture. It is compatible across multiple voltage and frequency configurations within the PS4 submersible pump family, including 220V/60Hz, 440V/60Hz, 400V/50Hz High Head, and 400V/50Hz High Output variants. Keeping hardware components like this washer in good condition is essential to maintaining proper clamping loads and protecting adjoining seals and fasteners within the pump assembly.
Key Features
- Genuine OEM Specification: — Manufactured to the exact material grade and dimensional tolerances required for correct load distribution in the PS4 pump assembly.
- Drop-In Hardware Replacement: — Matches the original bore diameter, outer diameter, and thickness for correct seating without rework or shimming.
- Broad PS4 Family Coverage: — Confirmed fit across PS4-11003HH and PS4-11003HF submersible pump variants in both High Head and High Output configurations across 50Hz and 60Hz voltages.
- Protects Mating Surfaces: — Distributes fastener clamping load evenly, helping to prevent gasket damage, fastener pull-through, and surface deformation in the pump housing.
- Verified Part Number: — Part number 5000157361 is the confirmed Wacker Neuson OEM reference for this washer, making sourcing straightforward during routine service or repair.
A plain washer serves as a load-spreading interface between a fastener — such as a bolt or nut — and the surface it bears against. By distributing the clamping force across a wider area, it prevents the fastener from pulling into or damaging the material beneath it, and helps maintain consistent tension across the joint. In submersible pump assemblies like the PS4 series, where components are subject to vibration, hydraulic pressure, and wet operating environments, correctly specified hardware is critical. A missing, incorrect, or worn washer can lead to uneven clamping, fastener loosening, or damage to sealing surfaces that causes leaks or premature component failure.
