The Wacker Neuson 5100029776 is a genuine OEM Motor Housing designed for PS4-7503HF and PS4-7503HH submersible pumps. As a direct manufacturer replacement, this part is produced to the same specifications as the original component installed at the factory, ensuring structural and dimensional compatibility with your pump's motor assembly. This Motor Housing is confirmed to fit multiple PS4 series configurations, including 100mm/4in submersible pump variants rated at 400V/50Hz High Output. When the original housing is cracked, corroded, or mechanically damaged, replacing it with part number 5100029776 restores the integrity of the motor enclosure and keeps the unit operating as intended.
Key Features
- Genuine OEM Structural Integrity — Manufactured to Wacker Neuson's original dimensional and material tolerances, ensuring the motor assembly seats, seals, and aligns correctly within the pump body.
- Direct Swap for PS4 Series Pumps — Engineered to drop directly into PS4-7503HF and PS4-7503HH configurations without fitment modifications, matching all original mounting points and bore dimensions.
- Broad PS4 Series Compatibility — Covers multiple PS4-7503HF and PS4-7503HH machine variants, including the 100mm/4in 400V/50Hz High Output submersible pump configuration.
- Protects Internal Motor Components — A sound motor housing maintains the watertight enclosure that protects the motor windings and bearings from the surrounding liquid. A compromised housing risks catastrophic motor failure and unplanned pump replacement.
- Submersible-Grade Construction — Built to withstand continuous immersion conditions, resisting the mechanical stress and environmental exposure inherent to submersible pump operation.
The motor housing is the structural outer enclosure that surrounds and protects the electric motor within a submersible pump. It maintains the watertight barrier between the motor's internal electrical components and the pumped liquid, while also providing the rigid framework that aligns the motor shaft, bearings, and pump end. When the housing is damaged — whether from impact, corrosion, or wear — that protective seal is compromised, allowing moisture ingress that can destroy the motor windings and bearings in a short period of operation. Replacing a failed or damaged housing promptly with a correctly specified part like the 5100029776 is essential to restoring full submersible pump performance and preventing further drivetrain damage.
