The Wacker Neuson 5100028482 is a genuine OEM Gasket & O-Ring Set designed for PS3 5503 and PS4 5503 series submersible pumps. Sourced directly from Wacker Neuson, this set delivers the exact sealing geometry and material composition specified for these pumps, ensuring proper fluid containment across the full range of operating voltages and configurations. Fitment covers PS3 5503 and PS4 5503 units across 220V/60Hz, 440V/60Hz, and 400V/50Hz configurations, as well as the 75mm/3in and 100mm/4in submersible pump variants in that series. When your pump starts showing signs of fluid bypass or leakage, replacing the gasket and o-ring set with part number 5100028482 restores the original sealed integrity of the assembly.
Key Features
- OEM Material Specification — Genuine Wacker Neuson sealing compounds sized and rated to the exact compression and chemical-resistance requirements of the PS 5503 pump family.
- Complete Sealing Set — Includes both gaskets and o-rings as a matched set, so all sealing surfaces are renewed together in a single service event.
- Broad PS 5503 Series Coverage — Fits PS3 5503 and PS4 5503 submersible pumps across 220V/60Hz, 440V/60Hz, and 400V/50Hz voltage configurations.
- Restores Pump Fluid Integrity — A failed or degraded seal allows water and debris to bypass internal pump passages, reducing flow efficiency and risking motor damage. Fresh seals bring pump output back to spec.
- Direct OEM Replacement — Part number 5100028482 matches the original engineering drawings, installing into existing housings and mating surfaces without rework or fitting adjustments.
Gaskets and o-rings are the primary fluid barriers within a submersible pump, sealing the interfaces between the pump housing, motor casing, and internal passages to prevent bypass flow and water ingress into electrical components. When these seals degrade — through heat cycling, chemical exposure, or age — the pump loses hydraulic efficiency, output pressure drops, and motor windings can be exposed to moisture, leading to premature failure. Replacing the Gasket & O-Ring Set at the first sign of leakage or during a scheduled service interval is the most cost-effective way to protect the pump motor and maintain consistent discharge performance.
