The centrifugal & shielded structure enhances operational stability and protects internal components from external contaminants. Equipped with PWM duty cycle speed regulation, it allows for precise flow control to match dynamic cooling requirements. Additionally, it incorporates comprehensive protection mechanisms against reverse connection, overvoltage, overcurrent, dry running, and overtemperature, ensuring safe operation even under extreme conditions. With an IP68 rating, the pump offers complete protection against dust and long-term submersion in water, making it suitable for harsh operating environments in energy storage facilities.

The OWP-BL43-440T Electric Coolant Pump is specifically engineered to meet the rigorous liquid cooling needs of energy storage battery cabinets, a critical application in the rapidly growing energy storage industry. Energy storage battery cabinets generate significant heat during charging and discharging cycles, and effective thermal management is essential to maintain battery performance, extend lifespan, and prevent safety hazards. This pump’s robust performance parameters—including a rated flow rate of 3000L/H at 20M head and a maximum flow rate of 5000L/H—ensure efficient circulation of cooling media (50-60% glycol + water mixture, dielectric oil, or electronic fluorinated solution) throughout the battery cabinet’s cooling system. Its maximum lift head of 23M enables reliable fluid movement even in complex piping layouts, while the 25mm outlet diameter facilitates optimal flow velocity. The -40℃ to 85℃ medium temperature range allows the pump to operate seamlessly in both extreme cold and high-heat environments, adapting to varying climatic conditions and operational loads. The PWM speed regulation function enables the pump to adjust flow rates in real time based on the battery cabinet’s heat generation, ensuring precise temperature control and energy efficiency. The high/low-level fault feedback signal provides real-time operational status updates, allowing for prompt troubleshooting and minimizing downtime. With IP68 protection and comprehensive safety features, the OWP-BL43-440T ensures uninterrupted operation in challenging conditions, safeguarding the battery cabinet’s performance and longevity. Whether used in large-scale energy storage plants, commercial backup power systems, or industrial energy storage solutions, this electric coolant pump delivers the reliability, efficiency, and durability required to support the stable operation of energy storage battery cabinets.
