Water Cooled Package Units (WCPU) are the backbone of cooling in many of Malaysia’s high-rise apartments and commercial offices. The internal circulation pump is responsible for moving water through the heat exchanger to reject heat; if this pump fails, the entire WCPU will "trip" on high pressure, leading to an immediate loss of cooling. EKG (Malaysia) Sdn Bhd provides specialized WCPU water pump replacement units and expert installation services to restore your system’s cooling capacity and prevent expensive compressor damage.
High-Rise Residential Apartments & Condominiums
Commercial Office Suites with Individual WCPU Units
Retail Lots & Shopping Center Units
Boutique Hotels & Hospitality Suites
Frequent "High Pressure" (HP) Trips – Insufficient water flow prevents the unit from cooling the refrigerant, causing system shutdowns.
Internal Water Leaks – Worn mechanical seals inside the WCPU cabinet can leak water into the electrical compartments.
Loud Grinding or Humming Noises – Signals bearing failure or a seized motor within the circulation unit.
Reduced Cooling Capacity – The AC feels "warm" despite the compressor running, often due to low flow rates.
Corrosion or Calcium Scaling – Heavy mineral buildup on the pump housing from cooling water reduces efficiency and leads to failure.
Selecting replacement pumps that match the exact GPM (Gallons Per Minute) and Head requirements of your specific WCPU model (e.g., Dunham-Bush, York, Carrier).
Ensuring the replacement motor matches the internal electrical voltage and phase of the unit.
Installation of compact, high-efficiency centrifugal pumps designed for confined WCPU cabinets.
Using pumps with corrosion-resistant impellers to handle the variations in treated cooling water.
Replacing all associated seals and gaskets during the pump swap to ensure a 100% leak-proof connection.
Verifying the integrity of internal piping connectors and flexible hoses.
Cleaning the internal Y-strainer and heat exchanger coils to ensure the new pump isn't immediately damaged by debris.
Removing scale and sludge from the immediate circulation loop.
Wiring the new pump to the internal PCB to ensure the "flow switch" safety logic is fully operational.
Testing the start/stop sequence to prevent water hammer and electrical surges.
Measuring water temperature differentials (Delta-T) to confirm optimal heat exchange.
Checking Amp draw of the new motor to ensure it is operating within factory specifications.
