The OWP-BL300H-D3-3 Electric Coolant Pump is engineered to deliver exceptional performance for immersion cooling applications, combining high flow rates, reliable lift capacity, and robust durability in demanding environments. Operating on a 48VDC power supply (with a wide input range of 42-54VDC), this 300W rated pump is optimized to handle critical thermal management tasks, ensuring efficient heat dissipation for sensitive electronic systems, industrial equipment, and specialized cooling setups. With a rated flow rate of 2880L/H at 17.5M lift and a maximum flow capacity of 5000L/H, it excels at circulating heat-transfer media—including 50-60% glycol-water mixtures, dielectric oil, and electronic fluorinated solutions—even under extreme temperature conditions ranging from -40℃ to 85℃ with guaranteed long-hour operation. Its IP68 waterproof rating ensures complete protection against dust and continuous submersion, making it ideal for immersion cooling systems where reliability in wet environments is non-negotiable. The pump’s PWM speed regulation allows for precise flow control, while the high/low-level fault feedback signal enables real-time monitoring, enhancing system safety and maintenance efficiency. Designed with a 50.5mm flange outlet diameter, it offers easy integration into existing cooling pipelines, ensuring seamless installation and compatibility with standard industrial fittings. Whether used in data centers, electric vehicle battery cooling, or industrial process systems, the OWP-BL300H-D3-3 stands out as a high-performance, durable solution that meets the rigorous demands of immersion cooling applications.

1. High Efficiency & Low Noise: Equipped with a closed impeller design, the pump achieves large flow rates while maintaining high operational efficiency and minimizing noise (≤60dB), ensuring quiet performance in noise-sensitive environments.
2. Compact & Energy-Saving: Adopting a permanent magnet brushless motor, it features a compact footprint and low power consumption, reducing installation space requirements and operational costs without compromising performance.
3. Extended Service Life: The shaft system utilizes ultra-high durability friction pair materials, significantly enhancing wear resistance and extending the pump’s service life to over 20,000 hours for long-term reliability.
4. Protective Shielded Structure: The shielded design provides additional protection to internal components, preventing contamination and ensuring stable operation even in harsh working conditions.
5. IP68 Waterproof & Wide Temperature Adaptability: With an IP68 rating and the ability to operate in -40℃ to 85℃, it offers superior environmental adaptability, suitable for both extreme cold and high-temperature immersion cooling scenarios.

The OWP-BL300H-D3-3 Electric Coolant Pump is specifically designed for Immersion Cooling applications. It is widely applicable in systems requiring efficient circulation of heat-transfer media, such as data center server cooling, electric vehicle (EV) battery thermal management, industrial machinery cooling, and specialized electronic equipment cooling. Its compatibility with multiple media types, robust waterproof design, and precise flow control make it a versatile solution for any immersion cooling setup that demands high performance, reliability, and long-term stability.
