The Wacker Neuson 5100028518 Motor Housing is a genuine OEM component designed for the PS4 7503HH and PS4 11003HH submersible pumps. As a direct OEM replacement, this housing is manufactured to the same specifications as the original, ensuring a proper fit within the pump's motor assembly. It is compatible across both the 220V and 440V/60Hz configurations of the PS4 7503HH and PS4 11003HH series. Using the correct Wacker Neuson 5100028518 Motor Housing helps maintain the structural and electrical integrity of the motor assembly in demanding pumping applications.
Key Features
- Genuine OEM Structural Integrity — Manufactured to the same dimensional tolerances as the original, ensuring the motor components seat and align correctly within the housing.
- Direct-Fit Replacement — Installs in place of the original housing without alteration, maintaining correct mounting points and sealing surfaces for the motor assembly.
- Broad PS4 Series Compatibility — Fits PS4 7503HH (10hp, 220V and 440V) and PS4 11003HH (15hp, 220V and 440V) submersible pump models.
- Protects Internal Motor Components — A sound motor housing contains and supports the motor's windings and bearings; a cracked or damaged housing can expose these components to moisture infiltration and premature failure.
- Electrical Safety Relevance — In submersible pump applications, a compromised motor housing can allow water ingress into live motor components, making housing integrity a genuine safety and compliance concern.
The motor housing on a submersible pump serves as the structural outer shell that encloses and protects the electric motor driving the pump impeller. It maintains the precise alignment of internal components — including the rotor, stator, and bearings — and forms a sealed barrier against the surrounding water. When the motor housing cracks, corrodes, or becomes damaged, it can allow moisture into the motor cavity, leading to winding failure, bearing damage, or electrical short circuits that take the pump out of service entirely.
