The Wacker Neuson Capacitor is a genuine OEM component designed for the PST2-400, PSA2-500, and PS2-500 series submersible pumps. Sourced directly from Wacker Neuson, this capacitor meets the original electrical specifications required to keep the pump motor starting and running correctly. Compatibility spans multiple machine numbers across the PST2-400, PSA2-500, and PS2-500 families, including 230 V configurations, so verify your machine number before ordering to confirm the correct fit.
Key Features
- Correct Electrical Rating: — Matched to the original capacitance and voltage spec for Wacker Neuson PS-series submersible pump motors — no guesswork on electrical compatibility.
- Genuine OEM Part: — Supplied by Wacker Neuson as part number 5000157388, ensuring the component is identical to what left the factory — not an approximation.
- Broad PST2/PSA2/PS2 Series Coverage: — Fits multiple machine configurations across the PST2-400, PSA2-500, and PS2-500 families, including 230 V variants.
- Restores Reliable Motor Start: — A worn or failed capacitor causes hard-starting or a motor that hums but won't turn over; replacing it gets the pump back to full duty quickly.
- Electrical Safety Compliance: — Using the correct OEM-rated capacitor protects the motor windings from overcurrent stress caused by an undersized or mismatched substitute.
A capacitor in a submersible pump motor provides the phase shift needed to start and run a single-phase induction motor. It supplies the extra starting torque that gets the pump impeller spinning from a dead stop, then — in run-capacitor designs — continues to improve motor efficiency during operation. When a capacitor degrades or fails, the motor may fail to start, draw excessive current, overheat, or trip the overload protector repeatedly. Replacing a faulty capacitor with the correct OEM part, such as the Wacker Neuson 5000157388, restores proper motor function and protects the rest of the pump's electrical system from secondary damage.
