Wacker Neuson 5100028656 Washer — Genuine OEM Submersible Pump Replacement

The Wacker Neuson Washer is a genuine OEM replacement designed for the PS2, PS3, and PS4 series submersible pumps, including the PS2-1503, PS3-1503, PS2-2203, PS3-2203, PS2-3703, PS3-3703, PS4-3703, PS3-5503, PS4-5503, PS4-7503HH, and PS4-7503HF models. Sourced directly from Wacker Neuson, this washer is manufactured to the same specifications as the original component fitted at the factory. It drops into position as a direct replacement, ensuring the correct seating, load distribution, and clamping integrity the pump assembly depends on. Whether you're servicing a 50mm, 75mm, or 100mm unit running on 400V/50Hz, part number covers a broad range of PS series configurations.

Key Features

• OEM-Grade Material and Dimensional Accuracy — Manufactured to Wacker Neuson's original tolerances, this washer delivers the correct load-bearing surface area and thickness needed for proper clamping force in submersible pump assemblies.
• Direct Drop-In Replacement — Matches the original mounting geometry exactly, seating flush without shimming, grinding, or modification to adjacent hardware.
• Broad PS Series Coverage — A single part number covers PS2, PS3, and PS4 submersible pump models from 50mm through 100mm outlet sizes, including HH and HF high-output variants.
• Maintains Proper Fastener Clamping — A correctly fitted washer distributes bolt or nut load evenly across mating surfaces, preventing stress concentration, surface damage, and fastener loosening under pump vibration.
• Genuine Wacker Neuson Part — Supplied as an authorized OEM component, backed by Wacker Neuson's parts program for confidence in fitment and sourcing accuracy.

A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it bears against. In submersible pump assemblies like the Wacker Neuson PS series, washers are critical to maintaining consistent clamping pressure across pump housings, motor mounts, and impeller hardware that operate under continuous vibration and water exposure. When a washer is worn, deformed, or missing, the fastener can work loose or damage the seating surface, leading to leaks, misalignment, or mechanical failure. Replacing it with the correct OEM part, such as Wacker Neuson 5100028656, restores the assembly to its designed clamping specification.
