The Wacker Neuson 5100028493 is a genuine OEM Gasket and O-Ring Set designed for the PS2-3703, PS3-3703, and PS4-3703 submersible pump series. As a direct OEM replacement, this set is sourced from Wacker Neuson and matched to the exact material grades, profiles, and tolerances specified for these pumps — ensuring proper compression and a leak-free seal across all mating surfaces. The 5100028493 covers multiple PS-series configurations, including 220V and 440V variants of the PS3-3703, making it a versatile service part for fleet operators and service technicians working across mixed pump inventories. Keeping a set on hand means seal failures can be addressed at the first sign of leakage rather than waiting on sourcing delays.
Key Features
- OEM-Grade Seal Materials — Each gasket and O-ring in this set meets Wacker Neuson's material specifications for compression resistance and fluid compatibility in submersible pump applications.
- Complete Set for Full Service — Includes all gaskets and O-rings needed for a thorough seal service, so technicians are not left short partway through a rebuild.
- Broad PS-Series Coverage — Fits the PS2-3703, PS3-3703 (including 220V/60Hz and 440V/60Hz configurations), and PS4-3703 submersible pumps in a single part number.
- Leak Prevention at the Source — Properly seated seals maintain pump efficiency and prevent water ingress into motor housings — a leading cause of premature submersible pump failure.
- Genuine OEM Part — Supplied as an authentic Wacker Neuson component, ensuring dimensional accuracy against OEM housing tolerances with no guesswork on fitment.
Gaskets and O-rings form the primary fluid barriers between mating pump components, preventing water from bypassing seals into areas it should not reach — including the motor cavity. In a submersible pump, degraded or compressed-out seals are one of the most common causes of motor flooding and pump failure. Replacing the full Gasket and O-Ring Set during service restores these barriers to specification and extends the serviceable life of the pump assembly.
