The Wacker Neuson Rotor is a genuine OEM component designed for the PST2 400, PS2 500, and PSA2 500 series submersible pumps. Sourced directly from Wacker Neuson, this rotor is manufactured to the same specifications as the original part fitted at the factory — ensuring a direct, compatible installation in your pump's motor assembly. This part is confirmed across a wide range of PST2 400, PS2 500, and PSA2 500 machine configurations, including 110 V and 230 V variants, giving you confidence that is the correct replacement regardless of your unit's voltage spec.
Key Features
- Genuine OEM Rotor Construction — Wound and balanced to the exact rotational tolerances required for Wacker Neuson submersible pump motors, maintaining correct motor output and efficiency.
- Direct Motor Assembly Fitment — Engineered to drop into the motor housing of compatible PST2 400, PS2 500, and PSA2 500 pumps without alteration to mounting points or shaft interfaces.
- Broad Series Coverage — Compatible across multiple PST2 400, PS2 500, and PSA2 500 configurations, including 110 V and 230 V variants, covering a wide span of Wacker Neuson submersible pump production runs.
- Restored Pumping Performance — A worn or failed rotor causes reduced motor torque, erratic pump output, or complete motor failure; replacing with 5000150590 restores full pumping capacity and consistent flow.
- Electrical Safety Compliance — As a core motor winding component operating in submerged, high-current conditions, using the correct OEM rotor maintains proper insulation ratings and safe motor operation.
The rotor is the rotating core of the pump's electric motor, responsible for converting electrical energy into the mechanical shaft rotation that drives the impeller. It works in tandem with the stator to generate the electromagnetic force that spins the pump; when the rotor degrades — through winding failure, imbalance, or physical damage — the motor loses torque and the pump's flow rate and pressure drop off sharply, or the motor stops running entirely. Replacing a faulty rotor with a correctly specified OEM part like the Wacker Neuson 5000150590 is essential for restoring full motor efficiency and protecting the surrounding motor components from secondary damage.
