The Wacker Neuson Oil Housing is a genuine OEM component designed for the PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF series submersible pumps. As a factory-sourced part, it meets the exact dimensional and material standards set by Wacker Neuson for these high-output and high-head electric submersible pump models. Compatible across a wide range of voltage configurations including 220V, 440V, 575V, and 400V variants, this oil housing serves the full PS4 submersible pump lineup. When the oil housing is compromised, bearing and mechanical seal lubrication is lost, risking rapid internal wear and pump failure.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's exact material and dimensional tolerances, ensuring the sealed oil chamber maintains correct fluid retention around the motor's mechanical components.
- Direct-Fit Replacement — Engineered to install in place of the original housing with no rework to the pump body, mating precisely with the motor casing and seal interfaces of PS4 series submersible pumps.
- Broad PS4 Series Coverage — Fits PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF models across 220V, 440V, 575V, and 400V/50Hz configurations.
- Preserves Motor Lubrication Integrity — A correctly sealed oil housing keeps the mechanical seal and bearings properly lubricated, sustaining pump output and preventing premature motor wear in continuous dewatering applications.
- Leak Prevention in Submersible Conditions — The housing is rated for full submersion, maintaining oil containment even under the hydraulic pressure and thermal cycling encountered during heavy-duty pumping operations.
The oil housing on a submersible pump encloses the oil-filled chamber that surrounds the mechanical seal and lower motor bearings, keeping them lubricated and protected from the water being pumped. Without a properly sealed housing, oil escapes into the pump cavity, the mechanical seal runs dry, and bearing failure follows quickly — often resulting in a seized or flooded motor. On the PS4 series electric submersible pumps, which are built for demanding dewatering tasks at significant horsepower ratings, maintaining the integrity of this housing is critical to sustaining long-term pump performance and protecting the motor investment.
