The Wacker Neuson 5100029919 is a genuine OEM Motor Housing designed for the PS4-1003HF and PS4-11003HH series submersible pumps, including the 100mm/4in Submersible Pump 400 V/50Hz High Head and High Output configurations. As a factory-original component, the 5100029919 is produced to the exact dimensional and material standards of the original part, ensuring a direct, trouble-free installation. This Motor Housing is the correct replacement for operators running PS4-series submersible pumps in demanding dewatering applications where structural integrity and motor protection are non-negotiable.
Key Features
- Genuine OEM Construction: — Cast and finished to the original dimensional spec, so the housing seals, mounts, and aligns with motor internals exactly as the factory design requires.
- Direct Bolt-On Replacement: — Engineered to match the original mounting pattern and port geometry of PS4-series submersible pumps, allowing straightforward swap-out without rework.
- Broad PS4-Series Coverage: — Confirmed fitment across the PS4-1003HF, PS4-11003HH, and both the 400 V/50Hz High Head and High Output submersible pump variants.
- Structural Protection for the Motor: — The housing encases and shields the motor assembly from water intrusion, abrasion, and impact, maintaining the submersible seal system that keeps the motor running in fully submerged conditions.
- Submersible Environment Rating: — Built to withstand continuous immersion; a cracked or compromised housing allows water into the motor cavity, leading to rapid winding failure and pump loss — the correct housing prevents this.
The motor housing on a submersible pump serves as the primary structural shell surrounding the electric motor assembly. It contains and protects the motor windings, bearings, and stator from the surrounding water while supporting the mechanical connection between the motor and the pump end. When the housing is cracked, corroded, or physically damaged, the motor's internal components are exposed to moisture ingress, which rapidly causes insulation breakdown, winding shorts, and complete motor failure. Replacing a compromised housing with the correct OEM part restores the sealed integrity the pump depends on to operate safely and continuously in submerged or flooded-site conditions.
