The Southern brand pump used in industrial chillers belongs to the vertical multistage centrifugal pump category (e.g., Nanfang Pump Industry’s CDL and CHL series). These pumps are specifically designed for industrial fluid transportation and are ideal for water circulation systems in chillers.
1. Strong Corrosion Resistance
Made of 304/316 stainless steel, it can withstand the water medium in the chiller for a long time (which may contain trace chemical additives), prevent rust and extend the service life.
2. High Efficiency & Energy-Saving
The optimized design of the hydraulic model, in combination with high-efficiency motors, has an energy efficiency ratio (such as IE3/IE4 standards) higher than that of ordinary water pumps. Long-term operation can significantly reduce the electricity consumption cost.
3. Compact Structure
Vertical multistage design achieves high head performance in minimal space, ideal for modular or compact chiller systems.
4. Low Noise & Vibration
Precision dynamic balancing and vibration-damping bases ensure noise levels below 70 dB, suitable for noise-sensitive environments like labs or workshops.
5. Easy Maintenance
Modular components (e.g., impellers, mechanical seals) allow quick replacement without disassembling pipelines, minimizing downtime.
6. High Reliability
Equipped with imported mechanical seals (e.g., Burgmann) and long-life bearings (e.g., SKF/NSK), supporting 24/7 continuous operation.
7. Wide Compatibility
Flow rates range from 1–240 m³/h, with heads up to 200+ meters, adaptable to chillers of various capacities (10RT to 1000RT).
8. Smart Control Compatibility
Certain models support variable frequency drives (VFDs), enabling flow adjustment based on cooling demand to save energy and reduce hydraulic shocks.
- Industrial Cooling: Plastic injection molding, laser equipment, CNC machining centers.
- HVAC Systems: Central air conditioning water circulation, cooling tower supply.
- Environmental Engineering: Water treatment, purified water transport.
If you require a specific model recommendation, parameters such as the cooling capacity, circulating water volume, and head requirements of the chiller should be provided. Nanfang Pumps are cost-effective than imported brands (such as Grundfos and Wilo) in terms of cost performance and localized services (such as spare parts supply and technical support), and are suitable for users who pay attention to long-term stable operation and cost control.
