The Wacker Neuson 5200012388 Capacitor is a genuine OEM component designed for PST3 750 and PSTF3 750 submersible pumps. As a direct OEM replacement, this capacitor is produced to the same specifications as the original, ensuring proper motor start and run performance in your pump. It is confirmed to fit the 220V/60Hz, 1HP variants of both the PST3 750 and PSTF3 750 series. When your submersible pump struggles to start, runs intermittently, or fails to reach operating speed, a failed capacitor is often the cause — and this part is the correct fix.
Key Features
- Correct Electrical Rating: — Matched to the 220V/60Hz motor specification of the PST3 750 and PSTF3 750 submersible pumps, ensuring proper capacitance output for reliable motor starting and running.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this capacitor meets the same electrical tolerances as the original factory component — no guesswork on compatibility.
- Direct Drop-In Replacement: — Designed to install in the same location as the original capacitor, with matching connections for a straightforward swap during service.
- Confirmed Fitment: — Fits the PST3 750 (part 5000620337) and PSTF3 750 (part 5000620338) submersible pump models, both 1HP, 220V/60Hz, 33-foot cord variants.
- Restores Full Motor Function: — A worn or failed capacitor causes hard-starting, humming without rotation, or complete motor failure; replacing it with the correct OEM part brings the pump back to full operating capacity.
- Electrical Safety Compliance: — Using the correct OEM-rated capacitor prevents overvoltage stress on the motor windings, protecting the pump's electrical system from further damage.
A capacitor in a submersible pump motor stores and releases an electrical charge to create the phase shift needed to start and sustain the motor's rotation. In single-phase motors like those found in the PST3 750 and PSTF3 750, the capacitor is critical — without it, the motor cannot generate enough torque to start under load. When a capacitor degrades or fails, symptoms include the pump humming without turning, tripping its thermal overload, or failing to start altogether. Replacing it promptly with the correct OEM-rated part restores the pump's ability to move water efficiently and prevents additional strain on the motor windings.
