The Wacker Neuson 5200023119 is a genuine OEM O-Ring designed for the PS4-11003HH and PS4-11003HF series submersible pumps. As a direct OEM replacement, this O-Ring is manufactured to the exact material grade and compression tolerances specified for these pumps, ensuring a proper hydraulic seal within the pump assembly. This part is confirmed to fit multiple PS4 series configurations, including 220V/60Hz high-horsepower units and 400V/50Hz high-head and high-output variants.
Key Features
- OEM-Grade Sealing Material — Manufactured to the exact elastomer compound and durometer spec required for submersible pump environments, maintaining compression integrity under continuous immersion.
- Drop-In Replacement — Dimensioned to seat directly into the original O-Ring groove on PS4 series pump housings with no reworking of mating surfaces.
- Broad PS4 Series Fitment — Compatible across PS4-11003HH and PS4-11003HF configurations, including 220V/60Hz and 400V/50Hz high-head and high-output models.
- Leak Prevention — A correctly seated O-Ring maintains the pressure boundary inside the pump casing; a deteriorated or missing O-Ring allows bypass leakage that reduces pumping efficiency and can cause motor damage from ingress.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number referenced in the machine's original service documentation.
An O-Ring in a submersible pump serves as a static seal between two mating housings or covers, preventing water from bypassing the pump's internal flow path and stopping external moisture from reaching sensitive motor components. When an O-Ring hardens, cracks, or is compressed beyond its usable range, the seal fails — leading to reduced output pressure, cavitation, or water intrusion into the motor housing. Replacing a worn O-Ring at the correct service interval is one of the most cost-effective ways to maintain full pumping performance and protect the motor on PS4 series submersible pumps.
