The Wacker Neuson Wear Ring is a genuine OEM component designed for PS2-500 and PSA2-500 series submersible pumps. As a direct factory replacement, this wear ring restores the precise clearance between the impeller and pump casing that efficient water movement depends on. It is compatible across multiple PS2-500 and PSA2-500 variants, including 230V configurations, making it a versatile service part for contractors running Wacker Neuson submersible pump fleets.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact clearance tolerances Wacker Neuson specifies for the PS2-500 and PSA2-500 pump housings, ensuring the impeller-to-casing gap is restored to original performance levels.
- Drop-In Replacement — Matches the original wear ring profile and seating geometry for a straightforward installation without reworking the pump casing or impeller.
- Broad PS2-500 and PSA2-500 Compatibility — Verified fitment across a wide range of PS2-500 and PSA2-500 submersible pump configurations, including standard and 230V variants.
- Restores Full Flow Performance — A worn or damaged wear ring increases internal recirculation, causing a measurable drop in discharge flow and pump efficiency. Replacing it brings output back to specification.
- Backed by Wacker Neuson OEM Standards — Sourced directly through Wacker Neuson's parts program, so material grade and dimensional specs match the original production component.
The wear ring is a close-tolerance component that sits between the rotating impeller and the stationary pump casing in a submersible pump. Its job is to minimize internal bypass — the leakage of pressurized water back to the inlet side — which directly controls how much flow and head pressure the pump can generate. As the ring wears over time, the clearance gap widens, internal recirculation increases, and the pump delivers noticeably less water per minute even though it continues to run. Replacing the wear ring is one of the most effective ways to return a tired submersible pump to its rated performance without a full rebuild.
