The OWP-BL43-450T Electric Coolant Pump is a high-performance thermal management component tailored to address the intense heat generation challenges of high-power DC charging stations. Engineered with industrial-grade durability and precision control, this pump ensures stable cooling for critical charging components, supporting fast and reliable EV charging while withstanding the demanding operational conditions of public and commercial charging infrastructure.

• Closed Impeller Design: Optimizes fluid movement to deliver exceptional pumping efficiency, paired with aerodynamic refinement that contributes to the ≤60dB noise level—suitable for urban and residential charging site deployments.
• Permanent Magnet Brushless Motor: Combines a compact form factor with low 250W rated power consumption, enabling space-efficient integration into charging station enclosures and reducing operational energy costs.
• Long-Lasting Shaft Assembly: Features ultra-durable friction pair materials, ensuring a service life exceeding 20,000 hours and minimizing maintenance needs for high-traffic charging facilities.
• Centrifugal & Shielded Construction: Isolates the motor from cooling media to prevent corrosion and contamination, enhancing reliability in continuous-duty charging scenarios.
• PWM Speed Regulation: Offers precise flow rate adjustment (from 6000L/H rated to 9000L/H max) to match real-time heat loads, optimizing cooling efficiency during peak charging periods.
• Comprehensive Protection Systems: Integrates reverse polarity, overvoltage, overcurrent, dry-run, and overtemperature protection to safeguard both the pump and charging station electronics from potential failures.

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.
