The Wacker Neuson Motor Housing is a genuine OEM component designed for the PS2-3703, PS3-3703, and PS4-3703 series submersible pumps. As a direct factory replacement, this housing ensures the internal motor assembly is correctly enclosed, supported, and protected within the pump unit. Wacker Neuson genuine OEM parts are manufactured to the same standards as the original components, making the a dependable choice when restoring your submersible pump to full working condition. Fitment spans a wide range of PS-series voltage configurations, including 220V, 440V, 575V, and 400V/50Hz variants across the 2-inch, 3-inch, and 4-inch pump families.
Key Features
- Genuine OEM Structural Integrity — Manufactured to original design tolerances, ensuring the motor assembly seats correctly within the housing without gaps or misalignment that could lead to moisture ingress or vibration damage.
- Drop-In Replacement for PS-Series Pumps — Engineered to install exactly as the original, mating to existing motor, seal, and pump body interfaces without modification.
- Broad PS-Series Compatibility — Fits PS2-3703, PS3-3703, PS4-3703, PS4-7503HH, and PS4-7503HF models across multiple voltage ratings, covering 2-inch, 3-inch, and 4-inch submersible pump configurations.
- Protects Critical Motor Components — A correctly fitted housing keeps water, debris, and pressure from compromising the motor windings and bearings; a cracked or damaged housing risks total motor failure and unplanned pump replacement.
- Electrical Safety Compliance — As a primary structural barrier between the submerged motor and the surrounding fluid environment, housing integrity is essential to safe operation of electric submersible pumps.
The motor housing on a submersible pump serves as the structural shell that encloses and protects the electric motor from the surrounding water and pumped media. It maintains the separation between internal electrical components and the external environment, which is critical for safe and efficient pump operation at depth. When the housing cracks, corrodes, or becomes damaged, the motor is exposed to moisture and contamination, leading to winding failure, bearing seizure, and ultimately complete pump failure.
