The Wacker Neuson 5200020235 Armature is a genuine OEM component designed for the APT4S and APT4T series submersible pumps. This includes the APT4S Pump with Skid, APT4S Pump with Skid Cold Weather, APT4T Pump with Surge Brake, APT4T Pump with Electric Brake, and their corresponding Cold Weather variants. As a factory-sourced part, the 5200020235 meets the exact electrical and dimensional specifications required for full motor performance in these pump models. Verify your model number before ordering to confirm compatibility with your specific APT4T or APT4S configuration.
Key Features
- Correct Winding Specification: — Manufactured to OEM electrical output specs, ensuring the armature generates the proper electromagnetic torque for the APT4S and APT4T pump motors.
- Genuine OEM Sourcing: — Sourced directly from Wacker Neuson, this armature matches the original component in commutator segment count, core length, and winding configuration for a direct swap.
- Broad APT4 Series Coverage: — Fits multiple APT4S and APT4T variants, including Surge Brake, Electric Brake, and Cold Weather-equipped models — one part number across the full APT4 pump lineup.
- Motor Output Restored: — A worn or shorted armature causes loss of pump speed, excessive heat, and motor failure. Replacing with part 5200020235 restores full rated flow and lift performance.
- Electrical Safety Compliance: — Correct armature resistance and insulation grade are critical in submersible pump motors operating in wet environments; this OEM unit meets those requirements as originally designed.
The armature is the rotating core of the pump's electric motor. It carries the wound copper coils that interact with the surrounding stator's magnetic field to produce the rotational force that drives the impeller. When an armature fails — through worn commutator surfaces, shorted windings, or physical damage — the motor loses torque, draws excessive current, or stops running entirely, halting pump operation. Replacing a failed armature with the correct OEM unit restores the motor to its original operating condition and protects surrounding motor components from damage caused by electrical imbalance.
