The Wacker Neuson Rotor is a genuine OEM component designed for the PST2 400, PS2 500, PSA2 500, PSR1 500, PSG2 500, and PSTF2 400 series submersible pumps. As a factory-sourced part, the meets the original design specifications and is the correct direct replacement for worn or failed rotors across these pump families. Fitment spans multiple voltage variants — including 110 V and 230 V configurations — so confirm your machine's model and voltage before ordering. Keeping the rotor in proper working condition is critical to maintaining full pump output and protecting the motor from damage caused by imbalance or bearing wear.
Key Features
- Genuine OEM Winding and Balance Spec — sourced directly from Wacker Neuson, this rotor meets the original electromagnetic and rotational balance tolerances required for consistent motor output in submersible pump applications.
- Drop-In Motor Replacement — engineered to seat and align within the existing motor housing without modification, restoring the pump's drive assembly to its original configuration.
- Broad PST2, PSA2, PS2, PSR1, PSG2, and PSTF2 Series Coverage — a single part number covers multiple pump models and voltage variants, including 110 V and 230 V builds across the PST2 400, PS2 500, and PSA2 500 families.
- Restores Full Pumping Capacity — a worn or damaged rotor reduces motor torque and pumping efficiency; replacing it with part 5000157367 brings discharge flow back to rated performance.
- Electrical Safety Compliance — as a genuine OEM rotor for submersible pump motors, this part maintains the insulation class and electrical integrity required for safe operation in wet and submerged environments.
The rotor is the rotating core of an electric motor — it spins in response to the magnetic field generated by the stator, converting electrical energy into the mechanical rotation that drives the pump impeller. In a submersible pump like the PS2 or PSA2 series, the rotor operates fully sealed within the motor housing and must maintain precise balance and correct electromagnetic properties to sustain efficient, low-vibration operation. When a rotor degrades — through bearing failure, winding damage, or physical wear — the motor loses torque, draws excess current, and can overheat, ultimately causing pump failure or motor burnout.
