The OWP-BL43-450T Electric Coolant Pump is specifically designed for heat dissipation in high-power DC charging stations, where efficient thermal management is critical to maintaining charging speed, component longevity, and user safety. With a maximum flow rate of 9000L/H and 11M lift head, the pump effectively circulates compatible cooling media (50-60% glycol-water mixture, dielectric oil, electronic fluorinated solution) to dissipate heat from power modules, capacitors, and other heat-generating components during rapid charging cycles. Its wide medium temperature range (-40℃ to 85℃) and IP68 protection grade ensure reliable operation in both indoor and outdoor charging environments, resisting dust, water, and extreme temperatures. The PWM speed control and high/low-level fault feedback signal enable seamless integration with charging station control systems, supporting real-time monitoring and adaptive cooling adjustments. This model’s compact size, low noise, and long service life make it an indispensable solution for enhancing the performance, reliability, and durability of high-power DC charging infrastructure.
