AC Pump Repair | Comprehensive HVAC Pump Restoration by EKG (Malaysia) Sdn Bhd

Why AC Pump Failure Needs Immediate Attention?

AC pumps are the lifeline of any HVAC system—circulating chilled water, removing condensate, and maintaining pressure. When they fail, cooling stops, humidity rises, and facilities overheat. A seized bearing, burnt motor, or blocked impeller doesn't resolve itself. Every hour of downtime risks equipment damage, product loss, and tenant discomfort. EKG (Malaysia) Sdn Bhd delivers complete AC pump repair—from motor rewinding to hydraulic restoration—for commercial, industrial, and critical cooling applications.

Our AC pump repair services cover:

• Chilled Water Circulation Pumps

• Condenser Water Pumps

• Condensate Removal Pumps

• Cooling Tower Pumps

• Booster & Pressure Pump Sets

• AHU/FCU Drain Pumps

Common AC Pump Failure Modes

• Motor Burnout – Winding failure, capacitor open, or thermal overload

• Mechanical Seal Leak – Water ingress, bearing contamination, shaft damage

• Impeller Wear/Breakage – Cavitation, debris impact, or corrosion

• Bearing Failure – Grease breakdown, misalignment, or water entry

• Blocked Volute/Inlet – Sludge, scale, or foreign object obstruction

• Coupling Misalignment – Excessive vibration and accelerated wear

• Loss of Prime – Air ingress, foot valve failure, or low water level
