With a rated flow rate of 2880L/H at 17.5M head and a maximum flow capacity of 5000L/H, it efficiently circulates cooling media while maintaining low noise levels and energy consumption, making it a top choice for high-performance industrial systems.

The OWP-BL300H-D3-3 Electric Coolant Pump integrates cutting-edge design features to enhance performance and durability. Equipped with a closed impeller, it achieves high flow rates and superior pump efficiency while minimizing operational noise (≤60dB), creating a quieter working environment. The permanent magnet brushless motor ensures compact dimensions and low power consumption, reducing energy costs without compromising performance. Its shaft system utilizes ultra-high-life friction pair materials, significantly extending the service life beyond 20,000 hours. Additionally, the shielded structure provides effective protection against external contaminants, while the IP68 rating ensures complete dustproof and waterproof performance, making it suitable for harsh industrial conditions.

The OWP-BL300H-D3-3 Electric Coolant Pump is specifically engineered to excel in liquid-cooled supercharger systems, where efficient heat dissipation and reliable operation are critical. Liquid-cooled superchargers generate substantial heat during high-speed operation, requiring a robust cooling solution to maintain optimal performance and prevent component damage. This pump’s key performance metrics—including a maximum flow rate of 5000L/H and maximum lift head of 22M—enable it to circulate cooling media (such as 50-60% glycol-water mixtures, dielectric oil, or electronic fluorinated solutions) quickly and effectively, ensuring rapid heat transfer away from critical supercharger components. The pump’s PWM speed regulation allows for precise control of flow rates, adapting to varying cooling demands and optimizing energy efficiency. With a wide operating temperature range of -40-85℃, it performs reliably in both extreme cold and high-heat environments, making it suitable for diverse industrial settings. The high/low-level fault feedback signal provides real-time monitoring, enabling timely maintenance and minimizing downtime. Its compact design and low noise output (≤60dB) ensure easy integration into supercharger systems without disrupting surrounding equipment. Backed by a service life exceeding 20,000 hours and IP68 waterproof/dustproof protection, the OWP-BL300H-D3-3 Electric Coolant Pump offers long-term reliability and peace of mind for liquid-cooled supercharger applications, delivering consistent performance that meets the rigorous demands of industrial cooling.
