The Wacker Neuson O-Ring is a genuine OEM sealing component designed for the PG2A, PG2, and PG2TA series dewatering pumps. Sourced directly from Wacker Neuson, this O-Ring meets the exact material and dimensional specifications of the original part installed at the factory. It is confirmed to fit multiple PG2-family configurations, including the 50mm/2in dewatering pump variants. When your pump shows signs of fluid weeping, seal degradation, or loss of prime, replacing the O-Ring with the correct OEM part restores a proper leak-free seal and keeps the pump operating at rated performance.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's original compound and durometer specification, ensuring the correct compression set and chemical resistance for pump fluid contact.
- Drop-In Replacement — Matches the original groove dimensions exactly, seating cleanly without trimming or adjustment during reassembly.
- Broad PG2 Family Coverage — Compatible with PG2A, PG2, and PG2TA dewatering pumps, including 50mm/2in discharge configurations.
- Leak-Free Pump Performance — A properly seated O-Ring maintains prime and prevents fluid bypass, allowing the pump to deliver its full rated flow and head pressure on site.
- Genuine Wacker Neuson Part — Carries part number 5000054958 for verified fitment accuracy when ordering through authorized channels.
An O-Ring in a dewatering pump forms a critical static or dynamic seal between mating housings, ports, or shaft assemblies, preventing water or fluid from bypassing the intended flow path. When an O-Ring hardens, cracks, or takes a permanent set, the pump loses its ability to maintain prime, and fluid can leak externally or internally — reducing output and causing the pump to work harder than designed. Replacing a worn O-Ring promptly with the correct part restores the sealed circuit and protects surrounding components from moisture damage.
