District Cooling System Water Pumps

High-capacity, high-reliability circulation for large-scale thermal networks.
District cooling system water pumps are the hydraulic engines that move massive volumes of chilled water from central plants through underground networks to multiple buildings. EKG Malaysia supplies, installs, and maintains these critical pumps—including primary plant circulation pumps, secondary distribution pumps, and energy transfer station (ETS) pumps—ensuring efficient, uninterrupted cooling supply across the network.

Key Pumping Roles in a District System:

• Primary Plant Circulation Pumps:

  • Duty: Move water through the central chiller evaporators.

  • Type: Often large horizontal split-case or vertical turbine pumps for extreme flow and reliability.

  • Feature: Constant or variable speed, with N+1 redundancy.

• Distribution Network Pumps:

  • Duty: Provide the pressure to push water through miles of primary supply and return piping.

  • Type: High-head multi-stage or large split-case pumps.

  • Feature: Often in duty/assist/standby configuration for 100% uptime.

• Energy Transfer Station (ETS) Pumps:

  • Duty: Circulate water between the primary network and the secondary loop of an individual building.

  • Type: Typically end-suction or in-line pumps with VFDs.

  • Feature: Pre-packaged skids with heat exchangers, controls, and instrumentation.

Critical Design & Reliability Factors:

• Hydraulic Modeling: Essential for accurate pump sizing given the massive scale and dynamic loads of a network.

• Material Durability: Pumps handling treated or raw water require bronze-fitted, stainless steel, or coated components to combat corrosion over decades.

• Redundancy & Availability: Design for N+1 or 2N pump configurations to ensure continuous cooling, a non-negotiable for district cooling operators.

• Energy Efficiency: Even small efficiency gains result in massive operational savings. VFDs are standard for load matching.

• Monitoring & Control: Integration with central SCADA for remote monitoring, pressure/flow control, and predictive maintenance.

The heartbeat of a reliable district energy network.
A district cooling system is only as reliable as its pumps. They must be engineered for decades of continuous, fault-tolerant operation.
