The Wacker Neuson Rotor is a genuine OEM Rotor designed for the PS2-3703, PS3-3703, and PS4-3703 series submersible pumps. As a factory-sourced component, this Rotor is manufactured to the exact tolerances and specifications required for correct motor operation across the full PS 3703 pump family, including 220V and 440V configurations. Verify your model number against the fitment list below before ordering to ensure this is the correct part for your machine.
Key Features
- Genuine OEM Winding Tolerances — Manufactured to exact magnetic and dimensional specifications, ensuring correct electromagnetic output and motor balance in the pump's drive assembly.
- Direct Drop-In Replacement — Engineered to match the original rotor's shaft diameter, stack length, and bearing seat dimensions for straightforward installation in the existing motor housing.
- Broad PS 3703 Series Coverage — Confirmed fitment across PS2-3703, PS3-3703, and PS4-3703 models, including 220V/60Hz and 440V/60Hz variants.
- Sustained Pumping Performance — A correctly seated rotor maintains motor speed and torque output, allowing the pump to move water at its rated capacity; a worn or imbalanced rotor causes overheating, vibration, and loss of flow.
- Electrical Safety Compliance — As a motor winding component in a submersible electric pump, using the correct OEM rotor is critical to maintaining proper motor insulation ratings and safe operation in wet environments.
The rotor is the rotating core of the electric motor inside a submersible pump. It works alongside the stator to convert electrical energy into the mechanical rotation that drives the impeller and moves water. When a rotor becomes worn, damaged, or out of balance, the motor loses efficiency, runs hot, draws excessive current, and can ultimately seize — leaving the pump unable to move water at all. Replacing a failed rotor with the correct OEM part restores full motor function and protects surrounding motor components from secondary damage.
