Electric chiller water pump

Electric Chiller Water Pump High-Efficiency Drive Solutions by EKG (Malaysia) Sdn Bhd

Precision Electrical Power for Optimal Chiller Circulation
An electric chiller water pump utilizes an integrated high-efficiency electric motor to provide precise, reliable circulation through your chiller's evaporator and condenser circuits. In modern chiller plants, these pumps represent a major opportunity for energy savings and intelligent control. EKG (Malaysia) Sdn Bhd specializes in electric pump solutions for chillers—from premium efficiency motor selection to advanced variable speed integration—ensuring your cooling system operates at peak performance with minimal energy consumption.

Core Advantages of Modern Electric Chiller Pumps

• High Efficiency Operation: Equipped with IE3, IE4, or IE5 class motors that significantly reduce operating costs compared to older standard efficiency models.

• Precise Speed Control: Easily integrated with Variable Frequency Drives (VFDs) for exact flow matching to chiller load.

• Smart Connectivity: Designed for seamless integration with Building Management Systems (BMS) and chiller plant sequencing controls.

• Reliable Continuous Duty: Built for 24/7 operation during cooling seasons, with robust insulation and protection systems.

• Compact & Integrated Designs: Many models combine pump and motor into a single, space-saving unit.

Critical Applications in Chiller Systems

• Primary Chilled Water Circulation: Moving water through the chiller evaporator to cooling coils.

• Condenser Water Circulation: Circulating water between the chiller condenser and cooling tower.

• Variable Primary Flow Systems: Where pump speed directly responds to chiller demand.

• Primary-Secondary Systems: Serving as secondary loop distribution pumps.
