OWP-BL43-426C 240W 2400L/H 24VDC Brushless Electric Coolant Pump for Chiller System

The OWP-BL43-426C is a high-efficiency 24VDC brushless DC electric coolant pump specially optimized for chiller cooling circulation systems. With a rated power of 240W, a rated flow of 2400L/H at 17m head and a maximum flow of 5000L/H and 20m lift head, this pump delivers stable and powerful liquid circulation performance. Adopting single-stage centrifugal structure and magnetic force transmission shield pump design, it eliminates mechanical seal wear, supports PWM speed regulation and constant flow control, and integrates comprehensive safety protection functions. Featuring IP68 full waterproof grade, ultra-wide operating temperature range and low noise operation below 60dB, the pump supports long-term continuous operation over 20000 hours, compatible with glycol-water mixture, dielectric oil, mineral oil and electronic fluorinated solution, serving as a reliable core circulation component for industrial chiller systems.

Industrial chillers require continuous, stable and precise liquid circulation to ensure consistent heat dissipation efficiency and stable equipment operation. Conventional circulation pumps often face typical defects: unstable flow output causes unbalanced heat exchange and fluctuating chiller cooling capacity; insufficient protection design leads to easy damage from dry running, overvoltage, overcurrent and over temperature, resulting in frequent shutdowns; narrow temperature adaptability fails to cope with complex industrial ambient temperatures; short service life and high noise increase operating and maintenance costs. In addition, ordinary pumps have poor medium compatibility and fixed speed, which cannot meet the adjustable and diversified circulation demands of modern high-precision chiller systems.

The OWP-BL43-426C perfectly solves the above pain points with integrated high-performance design. The built-in constant flow control ensures steady liquid circulation, stabilizing chiller heat exchange efficiency and avoiding cooling capacity deviation. Full-protection design including reverse polarity protection, dry running protection, overvoltage, overcurrent, overload and overtemperature protection effectively prevents equipment failure in complex working conditions. The magnetic transmission brushless motor achieves low power consumption, low noise and ultra-long service life, greatly reducing later maintenance frequency. Equipped with flange quick-connect structure for fast installation and PWM stepless speed regulation, it can flexibly adjust flow according to chiller real-time heat load. IP68 high protection and -40℃ to +85℃ ultra-wide temperature resistance enable stable operation in harsh industrial environments, while multi-medium compatibility adapts to various chiller cooling schemes.

Industrial Chiller Cooling Circulation System

Powered by a high-efficiency brushless DC motor and driven by magnetic force transmission, the pump isolates the motor from the liquid medium without mechanical contact friction. The centrifugal impeller rotates stably to drive cooling medium circulation, generating stable flow and lift for chiller heat exchange. The built-in constant flow module calibrates flow in real time to offset pipeline loss and voltage fluctuation. Meanwhile, the intelligent monitoring system triggers multi-protection mechanisms under abnormal conditions and feeds back fault signals. Combined with PWM speed regulation, it dynamically matches the chiller’s heat dissipation demand to maintain efficient and stable circulating cooling.

In industrial chiller and CDU cooling system matching, the industry generally adopts a conventional calibration habit that 1.5L/min flow corresponds to 1KW heat dissipation power. Converted from its rated 2400L/H (40L/min) flow rate, this pump is suitable for chiller systems with heat dissipation power within about 26KW. Its maximum 5000L/H flow can adapt to higher heat load scenarios. Users can comprehensively select the model according to actual heat dissipation power, pipeline loss and working environment.
