The Wacker Neuson Protection Plate is a genuine OEM component designed for the PS3-5503, PS4-5503, PS4-7503HH, and PS4-7503HF series submersible pumps. As a factory-original part, the is manufactured to the exact same specification as the component installed at the time of production, ensuring a correct, consistent fit across all compatible pump configurations. This protection plate is available to suit a wide range of voltage and frequency variants — including 220V/60Hz, 440V/60Hz, and 400V/50Hz models — covering both 7.5hp and 10hp pump ratings. If your Wacker Neuson submersible pump needs this plate replaced, sourcing the genuine OEM part is the straightforward way to restore it to proper working condition.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to the original design specification, with the same material grade and dimensional tolerances as the factory-fitted component.
- Direct-Fit Replacement — Mounts in the original position without alteration, maintaining correct alignment with surrounding pump housing components on all compatible models.
- Broad Model Coverage — Fits the PS3-5503, PS4-5503, PS4-7503HH, and PS4-7503HF submersible pump series across multiple voltage and frequency configurations.
- Structural Defense for Critical Pump Components — A sound protection plate shields internal or external pump elements from impact, debris, and abrasion — a worn or damaged plate leaves those components exposed to premature failure in demanding site conditions.
- Verified Part Number — Part number 5100028481 cross-references directly to the models listed, giving you confidence you are ordering the correct plate before it ships.
The protection plate on a submersible pump acts as a physical barrier, guarding vulnerable pump components against impact damage, grit ingress, and abrasion during operation in muddy or debris-laden water. Because submersible pumps are routinely deployed in harsh, uncontrolled environments — construction site dewatering, flood response, or groundwater extraction — this plate takes considerable punishment over time. When it becomes cracked, deformed, or missing entirely, the components it shields are left exposed, increasing the risk of accelerated wear or damage that can take the pump out of service.
