Equipped with constant flow control, the OWP-BL43-300 maintains consistent cooling performance, critical for regulating temperatures in high-power EV charging stations. It integrates multiple protection mechanisms—including reverse polarity protection, dry running protection, over-voltage/over-current protection, and overload/over-temperature protection—to prevent damage and ensure long-term reliability. The magnetic force transmission (shield pump structure) enhances operational safety and efficiency, while the high-efficiency brushless DC motor reduces power consumption and extends service life beyond 20,000 hours.
What sets this pump apart is its superior efficiency, achieved through professional electromagnetic theory design verification that boosts motor efficiency by 3-5% compared to competitors. Additionally, advanced hydraulic design simulation via professional software optimizes the match between the impeller and volute, delivering higher hydraulic efficiency. Built with automotive-grade electronic components, it withstands extreme temperatures, humidity, and voltage fluctuations, making it perfectly suited for the demanding conditions of EV supercharging infrastructure.
High-power EV charging stations generate significant heat during fast charging, which can affect charging speed, battery life, and safety. The OWP-BL43-300 addresses this challenge by providing efficient liquid cooling, efficiently dissipating heat from charging modules, batteries, and power electronics. Its wide working temperature range (-40℃ to +85℃) and IP68 waterproof rating ensure reliable operation in both indoor and outdoor installations, while the PWM speed regulation allows for dynamic adjustment based on real-time cooling demands. With low noise (≤60dB) and a long service life, this pump offers a cost-effective, low-maintenance cooling solution that supports the seamless expansion of high-power EV charging networks.
