Double Suction Pump for District Cooling

High-capacity, high-reliability circulation for large-scale thermal networks.
Double suction pumps are the preferred choice for district cooling primary circulation due to their ability to handle extremely high flow rates with balanced axial thrust, ensuring long bearing life and stable operation. EKG Malaysia supplies, installs, and maintains these robust pumps, providing the hydraulic backbone for efficient, reliable district cooling plant and distribution networks.

Why Double Suction Pumps Excel in District Cooling:

• High Flow Capacity: Ideal for the massive water volumes required in district cooling mains (flows of 1,000+ m³/hr are common).

• Axial Hydraulic Balance: The dual-sided impeller design minimizes axial thrust, drastically reducing bearing load and wear for 24/7 operation.

• High Efficiency: Operates efficiently across a broad range of its performance curve, crucial for varying district loads.

• Maintenance Friendly: Horizontal split-case design allows full inspection of the rotor and bearings without disturbing suction or discharge piping.

• Durability: Built with heavy-duty components for decades of continuous service.

Typical District Cooling Applications:

• Primary Plant Circulation: Moving chilled water from central chillers to the distribution network.

• Energy Transfer Station (ETS) Pumps: Circulating water between the primary network and secondary building loops.

• Large Campus or High-Density Urban Cooling Networks.

Critical Design & Selection Factors:

1. System Head & Flow: Precise hydraulic analysis of the entire network is essential for correct pump selection.

2. Redundancy Strategy: Typically installed in N+1 or duty/assist/standby configurations for 100% network reliability.

3. Material Selection: Often cast iron or ductile iron casings with bronze or stainless steel internals to handle treated water. For aggressive water, full stainless steel may be specified.

4. Control & Efficiency: Integrated with Variable Frequency Drives (VFDs) to match pump output to daily and seasonal load variations, maximizing energy savings.

Our District Cooling Pump Services:

• Hydraulic Network Modeling: Assisting in pump specification based on system simulation.

• Complete Pump Package Supply: Including pump, motor, baseplate, coupling, and often a factory-mounted VFD.

• Professional Installation & Precision Alignment: Critical for long-term reliability of these high-value assets.

• Commissioning & Performance Testing: Verifying the pump operates on its curve and integrates with network controls.

• Long-Term Service Agreements: Providing scheduled maintenance, vibration monitoring, and overhaul services.
