Chiller Pump

Essential circulation for efficient chiller operation and heat transfer.
A chiller pump is a critical component that circulates water through a chiller's evaporator (chilled water) and condenser (condenser water), enabling effective heat absorption and rejection. EKG Malaysia supplies, installs, and maintains a full range of robust, energy-efficient pumps specifically designed for the demanding duty of chiller plants in commercial, industrial, and district cooling applications.

Our Chiller Pump Solutions:

• Chilled Water Pumps (Evaporator Side):

  • Duty: Circulate water through the chiller evaporator and building cooling coils.

  • Types: End-suction, in-line, or split-case pumps, often in Primary, Secondary, or Variable Primary Flow (VPF) configurations.

  • Key Requirement: Must maintain design flow for efficient chiller operation and proper dehumidification.

• Condenser Water Pumps (Condenser Side):

  • Duty: Circulate water through the chiller condenser and cooling tower.

  • Types: Typically end-suction or split-case pumps built with corrosion-resistant materials.

  • Key Requirement: Must handle varying tower conditions and water treatment chemicals.

Key Selection & Design Considerations:

• Correct Hydraulic Sizing: Pump must be sized for the actual system head (chiller pressure drop + piping + valves + coils), not just the chiller nameplate flow.

• Material Compatibility:

  • Chilled Water: Closed loop; standard cast iron/bronze often suitable.

  • Condenser Water: Open loop; requires bronze-fitted, stainless steel, or coated components to resist corrosion and scale.

• Energy Efficiency: High-efficiency (IE3/IE4) motors and Variable Frequency Drives (VFDs) are strongly recommended to match pump output to load, saving 30–50% in energy.

• Reliability & Redundancy: Critical systems use duty/standby pumps to ensure 24/7 cooling availability.

Why Professional Pump Selection is Critical for Chillers:

• Protects the Chiller: Incorrect flow can cause evaporator freeze-up, low delta-T, or high head pressure, leading to damage.

• Maximizes Plant Efficiency: A pump operating at its Best Efficiency Point (BEP) reduces whole-plant energy consumption.

• Ensures System Stability: Proper sizing prevents control issues and temperature fluctuations.

Our Chiller Pump Services:

1. System Analysis & Pump Selection: We calculate the system curve to specify the optimal pump.

2. Supply & Installation: Providing the correct pump, motor, drive, and ancillaries.

3. Commissioning & Balancing: Verifying design flows, setting controls, and balancing the system.

4. Maintenance & Optimization: Scheduled service, performance checks, and efficiency upgrades.

The right pump ensures peak chiller performance.
Efficient, reliable circulation is non-negotiable for a cost-effective chiller plant.
