The Wacker Neuson is a genuine OEM O-Ring designed for the PS2, PS3, PS4, PST2, PST3, PSA2, PSG2, PSR1, and PSTF series submersible pumps. Sourced directly from Wacker Neuson, this O-Ring meets the exact material and dimensional specifications of the original component. It is confirmed to fit a wide range of submersible pump configurations across 2-inch, 3-inch, and 4-inch discharge models in both 50Hz and 60Hz variants. If your submersible pump is showing signs of leakage or has been opened for service, replacing part is a straightforward step to restoring a proper seal.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original elastomer compound and cross-section specification, ensuring consistent compression and leak-free sealing under submersible operating pressures.
- Drop-In Service Replacement — Matches the original groove geometry on PS-series pump housings, seating correctly without trimming or modification during reassembly.
- Broad PS-Series Compatibility — Fits PS2, PS3, PS4, PST2, PST3, PSA2, PSG2, PSR1, and PSTF series submersible pumps across multiple voltage and frequency configurations.
- Maintains Pump Watertight Performance — A correctly seated O-Ring prevents water ingress into the motor cavity; a degraded or missing O-Ring can lead to motor damage and pump failure.
- Critical Fluid Barrier in Electrical Equipment — In submersible pumps, maintaining a proper seal between wet and electrical sections is essential for safe, code-compliant operation in dewatering applications.
An O-Ring in a submersible pump acts as the primary static seal between housing sections, keeping water from entering the motor chamber and preventing pumped fluid from bypassing the pump's internal flow path. In submersible applications, this seal is under constant hydrostatic pressure, and even minor degradation from age, heat cycling, or chemical exposure can allow water to reach the motor windings — leading to insulation failure and motor burnout. Replacing the O-Ring as part of any pump disassembly or routine service inspection is standard practice for maintaining long-term pump reliability.
