High-Power EV Charging Station Cooling Electric Coolant Pump OWP-BL300H-D3-3:

The OWP-BL300H-D3-3 Electric Coolant Pump is a high-performance, reliable cooling solution specifically engineered for high-power EV charging stations, where efficient heat dissipation is critical to ensure operational stability and extend equipment lifespan. This 48VDC (42-54VDC operating range) pump delivers a rated power of 300W, combining impressive flow capacity and lift performance to meet the demanding cooling needs of fast-charging infrastructure. With a rated flow rate of 2880L/H at 17.5M head and a maximum flow of 5000L/H, it efficiently circulates cooling media to maintain optimal temperatures, while its 22M max lift head ensures consistent performance even in complex piping systems. Designed to withstand extreme conditions, the pump operates seamlessly with glycol (50-60%) + water mixtures, dielectric oil, and electronic fluorinated solutions, across a wide medium temperature range of -40℃ to 85℃ with guaranteed long-hour operation—making it suitable for both indoor and outdoor charging station environments. Equipped with a 50.5mm flange outlet for easy installation and compatibility with standard piping, it also features PWM speed regulation for precise flow control, allowing users to adjust performance based on real-time cooling requirements. The inclusion of high/low-level fault feedback signals enables proactive maintenance and system monitoring, while its IP68 waterproof rating ensures complete protection against dust and water submersion, enhancing durability in harsh working conditions. With a noise level limited to ≤60dB, it operates quietly, and a service life exceeding 20000 hours minimizes downtime and replacement costs, delivering long-term value for EV charging station operators.
