AC Pump Motor Repair | Expert Rewinding & Electrical Overhaul by EKG (Malaysia) Sdn Bhd

Why AC Pump Motor Failure Needs Immediate Attention?

The motor is the heart of any AC pump. When it burns out, seizes, or trips on overload, cooling stops immediately. No chilled water circulation. No condensate removal. No pressure boosting. Most facilities replace the entire pump—costly and unnecessary. AC pump motors can be rewound, reconditioned, and restored to like-new condition at a fraction of replacement cost. Without expert motor repair, facilities face extended downtime, inflated capital expenditure, and avoidable system replacements. EKG (Malaysia) Sdn Bhd delivers precision AC pump motor repair—rewinding, bearing replacement, and full electrical testing—for HVAC, industrial, and commercial pumping applications.

Our AC pump motor repair services cover:

• Chilled Water Circulation Pump Motors

• Condenser Water Pump Motors

• Condensate Removal Pump Motors

• Cooling Tower Pump Motors

• Booster Set & Pressure Pump Motors

• AHU/FCU Drain Pump Motors

Common AC Pump Motor Failure Modes

• Winding Burnout – Overheating, voltage imbalance, phase loss, or insulation breakdown

• Bearing Failure – Grease degradation, water ingress, or excessive radial load

• Capacitor Failure – Start/run capacitor open, shorted, or degraded

• Stator Short Circuit – Turn-to-turn or phase-to-phase insulation failure

• Rotor Damage – Broken rotor bars or eccentricity causing vibration

• Moisture Ingress – Condensation or seal failure reducing insulation resistance

• Overload Trip – Mechanical binding or undersized motor protection
