The Wacker Neuson is a genuine OEM O Ring Set Gasket designed for PS4-11003HH and PS4-11003HF series submersible pumps. As a factory-sourced assembly, this set delivers the exact sealing geometry and material specification engineered for these pumps across a wide range of voltage configurations, including 220V, 440V, 575V, and 400V/50Hz models. Sourcing a genuine OEM set means every ring in the kit is matched to Wacker Neuson's original tolerances — no guesswork on sizing or durometer. Keeping the sealing system intact is critical for submersible pump performance, making the a key part of any preventive maintenance or leak-repair service.
Key Features
- Genuine OEM Sealing Integrity: — Each O-ring in this set is produced to Wacker Neuson's original material and compression specifications, ensuring the correct sealing force at every joint in the pump housing.
- Complete Set, Single Part Number: — The 5000151023 supplies all required O-rings as a matched kit, eliminating the need to source individual rings separately and ensuring nothing is missed during reassembly.
- Broad PS4 Series Compatibility: — Fits both the PS4-11003HH High Head and PS4-11003HF High Output submersible pump families across multiple voltage configurations — 220V, 440V, 575V, and 400V/50Hz variants.
- Leak Prevention at the Source: — Worn or damaged O-rings allow water ingress into the motor housing or permit pumped fluid to bypass sealing surfaces, leading to motor damage and loss of output pressure. This kit restores the full sealing barrier.
- Submersible-Grade Material: — Engineered to withstand continuous immersion and the mechanical stress of pump operation, including vibration and pressure cycling encountered in dewatering and construction site applications.
O-rings and gaskets in a submersible pump create the fluid-tight barriers that keep water out of the motor cavity and prevent pumped media from bypassing the pump's internal flow path. Over time, these seals degrade due to compression set, chemical exposure, and the constant pressure cycling of pump operation — leading to leaks, reduced output, or catastrophic motor flooding if left unaddressed. Replacing the full O Ring Set Gasket during any pump disassembly restores the complete sealing system and protects the motor and impeller from damage caused by fluid intrusion.
