The Wacker Neuson is a genuine OEM Oil Seal designed for the PS2-3703, PS3-3703, PS4-3703, PS3-5503, and PS4-5503 series submersible pumps. As a factory-sourced component, it meets the exact material and dimensional standards set by Wacker Neuson for these pump families, covering a wide range of voltage configurations from 220V and 440V 60Hz models to 400V 50Hz and 575V 60Hz variants. Installing the correct OEM Oil Seal keeps the pump's internal drive components protected from water intrusion and ensures the unit continues to deliver full performance in demanding dewatering applications.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's exact compound and hardness specification, delivering the compression retention needed to maintain a watertight barrier around the pump shaft under continuous submersed operation.
- Direct-Fit Replacement — Dimensioned to seat correctly in the original seal housing of PS2-3703, PS3-3703, PS4-3703, PS3-5503, and PS4-5503 submersible pumps with no machining or adaptation.
- Broad Voltage Coverage — A single part number covers 220V, 440V, 575V (60Hz), and 400V (50Hz) pump variants across the PS3703 and PS5503 families, simplifying parts stocking for mixed fleets.
- Protects Motor and Drive Components — A functioning oil seal prevents water from migrating past the shaft and into the motor housing; a worn or cracked seal allows water ingress that can cause rapid bearing failure and motor burnout.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, ensuring the component matches the original design intent for PS-series submersible dewatering pumps.
An oil seal in a submersible pump sits at the point where the rotating drive shaft exits the pump's motor housing. Its job is to create a pressurized barrier that keeps the surrounding water out of the motor cavity while allowing the shaft to spin freely. Over time, exposure to abrasive slurries, heat cycling, and continuous rotation causes the seal lip to harden and crack, allowing water past the barrier. Once water reaches the motor bearings and windings, the resulting damage is typically irreversible — making timely oil seal replacement one of the most cost-effective maintenance tasks on any submersible pump.
