The Wacker Neuson is a genuine OEM O-Ring Gasket Set designed for PS3-5503 and PS4-5503 series submersible pumps. Sourced directly from Wacker Neuson, this set delivers the exact material grades, tolerances, and compression ratings needed to maintain a watertight seal in demanding dewatering applications. It is compatible across a wide range of PS3-5503 and PS4-5503 pump configurations, including 220V, 440V, 575V, and 400V/50Hz variants. Confirming the part number against your machine's serial plate before ordering ensures a correct, hassle-free installation.
Key Features
- OEM-Grade Seal Materials — Each O-ring in this set meets Wacker Neuson's original compression and chemical-resistance specifications, ensuring a leak-free seal under continuous submersible pump operating pressures.
- Complete Set for Full Service — Includes all O-rings and gaskets required for a thorough pump reseal, so technicians can complete the service without sourcing individual pieces separately.
- Broad PS-Series Compatibility — Fits PS3-5503 (75mm/3 in) and PS4-5503 (100mm/4 in) submersible pumps across multiple voltage configurations, including 220V, 440V, 575V, and 400V/50Hz models.
- Prevents Seal-Related Pump Failure — Worn or damaged O-rings allow water ingress into the motor housing, leading to winding damage and pump failure; replacing on schedule with the correct set protects the full pump assembly.
- Direct Drop-In Replacement — Engineered to the original dimensions and durometer ratings, this set installs into the existing seal bores without trimming, adaptation, or hardware changes.
O-rings and gaskets form the primary fluid barriers between the pump's internal components and the surrounding water column. In a submersible pump, these seals isolate the motor cavity from the pumped media — keeping water from reaching the motor windings while allowing the impeller and shaft to operate freely. When O-rings degrade, crack, or lose their compression set over time, water can migrate into the motor housing, causing electrical faults, overheating, and ultimately motor burnout. Replacing the full O-Ring Gasket Set at regular service intervals — or any time the pump is disassembled for inspection — is one of the most cost-effective ways to extend the service life of a PS3-5503 or PS4-5503 pump.
