The Wacker Neuson is a genuine OEM O-Ring Gasket Set designed for PST2 400 and PSTF2 400 series submersible pumps. As a direct Wacker Neuson OEM part, is manufactured to the exact material and dimensional specifications of the original components, ensuring proper compression and sealing performance across the pump assembly. This set covers the full range of PST2 400 variants, including 110V and 230V configurations, as well as the PSTF2 400 model. Keeping a genuine replacement set on hand means seal integrity can be restored quickly during scheduled maintenance or after an unexpected failure.
Key Features
- OEM-Grade Elastomer Compound — Each o-ring is produced from materials matched to the original specification, delivering the compression and chemical resistance needed in submersible pump environments.
- Complete Gasket Set — Includes all o-rings and gaskets required for the pump's sealing points, so the job can be completed in a single service interval without sourcing individual pieces separately.
- Drop-In Fitment for PST2 400 and PSTF2 400 — Confirmed for the full PST2 400 series (110V and 230V variants) and the PSTF2 400, replacing the originals at each sealing interface without rework.
- Leak Prevention at the Source — A correctly seated o-ring set maintains the pressure boundary between the pump's wet and dry sections; worn or damaged seals allow water ingress that can destroy the motor winding and bearings.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson and carries the part number 5000150811, giving you confidence that the geometry and durometer rating match what was installed at the factory.
O-rings and gaskets form the primary fluid barriers inside a submersible pump, sealing the motor housing, shaft entry points, and volute connections against water ingress and pressure loss. When these seals degrade — through age, abrasion from suspended solids, or chemical exposure — the pump can lose prime efficiency, allow water into the motor cavity, and ultimately suffer catastrophic internal damage. Replacing the full O-Ring Gasket Set at each major service interval is the most cost-effective way to protect the pump's motor and mechanical components and maintain rated flow performance.
