The Wacker Neuson is a genuine OEM Gasket and O-Ring Set designed for PST3 and PSTF3 series submersible pumps. As a direct OEM replacement sourced through authorized Wacker Neuson channels, this set delivers the correct material grades, compression ratings, and dimensional tolerances required to maintain a proper fluid seal across all mating surfaces. This kit covers the PST3 750 and PSTF3 750 models, including 110V and 220V/60Hz configurations, making it the right choice whether you're servicing a standard or float-switch-equipped unit. Keep a set on hand for planned maintenance or emergency seal replacement to restore your pump to full working order.
Key Features
- OEM-Grade Seal Materials — Each gasket and O-ring in this set is manufactured to Wacker Neuson's specified compound and durometer ratings, ensuring correct compression and leak-free seating at every joint.
- Complete Set for Full Service — Includes all gaskets and O-rings needed for a thorough seal service interval, so you're not sourcing individual pieces across multiple orders.
- Fits PST3 and PSTF3 750 Series — Compatible with PST3 750 and PSTF3 750 submersible pumps across 110V and 220V/60Hz variants, including float-switch-equipped PSTF3 configurations.
- Prevents Fluid Ingress and Pump Damage — Worn or failed seals allow water into motor cavities, leading to winding failure and pump loss. Fresh seals restore the barrier that keeps your pump running cleanly.
- Drop-In Replacement — Engineered to match original part geometry so components seat correctly during reassembly without rework or modification to mating surfaces.
The gaskets and O-rings in this set form the primary fluid barriers between mating housings, end caps, and internal pump components on Wacker Neuson PS-series submersible pumps. They prevent water from migrating into sealed motor cavities and stop pumped fluid from bypassing internal pressure chambers. When these seals degrade — through age, chemical exposure, or compression set — the pump may develop external leaks, lose prime efficiency, or allow moisture into the motor, ultimately causing winding failure and complete pump loss. Replacing the full set during any major service interval is the most effective way to restore seal integrity and extend pump service life.
