The water circulation pump is the lifeline of your Water Cooled Package Unit. When flow drops or the pump seizes, condenser cooling fails. Head pressure spikes. Compressor amperage surges. Efficiency collapses. Without immediate replacement, a failing pump forces premature WCPU retirement—or catastrophic compressor failure. EKG (Malaysia) Sdn Bhd delivers precision WCPU water circulation pump replacement, restoring design flow, stabilizing head pressure, and extending system life by 10+ years.
Our WCPU pump replacement services cover:
Condenser Water Circulation Pumps
Chilled Water Circulation Pumps
Closed-Loop Cooling Tower Pumps
Duty-Standby Configurations
Fixed-Speed & VFD-Controlled Installations
Motor Burnout – Continuous duty, voltage imbalance, insulation breakdown
Mechanical Seal Leakage – Water ingress into bearings; catastrophic failure imminent
Impeller Wear or Blockage – Erosion, cavitation damage, debris accumulation
Bearing Failure – Grease degradation, misalignment, water contamination
Casing Corrosion – Galvanic action, poor water treatment, age-related wall thinning
Reduced Flow / Pressure Drop – Undetected decay increasing compressor workload
VFD Drive Fault – Parameter corruption, IGBT failure, inadequate cooling

6. 24/7 Emergency Replacement
Immediate response for seized pumps
Temporary rental pump deployment
Express procurement available
Rising condenser approach temperature – Inadequate flow
Fluctuating discharge pressure – Worn impeller or failing motor
Audible cavitation – Suction starvation
Frequent compressor overload trips – Indirect condenser cooling failure
Visible seal leakage – Water loss, bearing contamination imminent
Vibration during operation – Bearing wear or misalignment
Age exceeding 12–15 years – 15–30% efficiency decay
We Recommend Replacement When:
Motor frame obsolete; spares unavailable
Casing corroded beyond safe repair
Repeated seal failures despite proper installation
Pump underspecified for current duty
Energy upgrade ROI <24 months
We Recommend Repair When:
Minor seal or bearing wear only
Motor rewinding viable
Impeller damage reparable
Pump <10 years, casing sound
Written repair-versus-replace analysis with every assessment. No bias. No upselling.
