The Wacker Neuson is a genuine OEM O-Ring Gasket Set designed for the PS4-11003HH and PS4-1003HF series submersible pumps. As a direct OEM replacement, this set is sourced from Wacker Neuson and engineered to meet the original sealing specifications of your pump — ensuring each o-ring seats and compresses exactly as the factory intended. Compatible across multiple PS4 configurations including 220V and 440V variants in both standard and high-output models, this kit covers a broad range of PS4-series applications in a single part number.
Key Features
- Genuine OEM Sealing Integrity — Each o-ring in this set is manufactured to the original material grade and compression profile specified for the PS4 submersible pump, so fluid sealing performance matches the machine's design.
- Complete Set for Efficient Servicing — All required o-rings and gaskets are included in one kit, allowing a full seal replacement in a single service event without sourcing individual components separately.
- Broad PS4 Series Compatibility — Fits PS4-11003HH and PS4-1003HF submersible pump models across 220V/60Hz and 440V/60Hz electrical configurations, covering both standard and high-output variants.
- Restores Submersion Sealing Performance — Worn or degraded o-rings allow water ingress into the motor housing, leading to electrical failure and pump shutdown. A fresh set restores the sealed environment the motor depends on.
- Critical for Electrical Safety in Submersible Operation — Proper sealing between wet and electrical zones is essential in submersible pumps. Compromised o-rings in this environment create a risk of motor damage and electrical hazard.
In a submersible pump, o-rings and gaskets form the critical barrier between the pumped fluid and the motor's electrical components. These seals prevent water from migrating into the motor housing, maintaining the dry, pressurized environment the motor requires to operate safely and continuously. When o-rings harden, crack, or deform over time, that barrier breaks down — allowing moisture intrusion that can cause winding failure, electrical shorts, and complete pump seizure. Replacing the full O-Ring Gasket Set at each major service interval is the most effective way to protect the motor and extend the working life of the pump.
