The OWP-BL43-440T electric coolant pump features a closed impeller design that enhances operational efficiency while keeping noise levels ≤60dB, suitable for the low-noise requirements of wind turbine installations. Adopting permanent magnet brushless technology, it boasts a compact profile and low power consumption, optimizing space allocation and energy efficiency within wind power systems. Its shaft system is constructed with ultra-long-life friction pair materials, combined with a centrifugal & shielded structure, ensuring a service life exceeding 20000 hours for consistent long-term reliability. Equipped with PWM duty cycle speed regulation, the pump enables precise flow control to adapt to the dynamic heat generation of wind turbine converters. Comprehensive protection functions include reverse connection, overvoltage, overcurrent, dry running, and overtemperature protection, effectively safeguarding the pump and the entire cooling system from potential damage. With an IP68 rating, it offers superior waterproof and dustproof performance, capable of withstanding harsh outdoor conditions such as strong winds, heavy rain, and dust in wind farms.
The OWP-BL43-440T electric coolant pump is specifically engineered to address the critical heat dissipation needs of wind turbine converters in the wind power industry. Wind turbine converters are core components that convert variable-frequency AC generated by the turbine into stable grid-compatible AC, and they produce substantial heat during high-power conversion processes—excessive temperatures can degrade converter efficiency, shorten component lifespan, and even cause unexpected failures, directly impacting the power generation capacity and operational safety of wind turbines. This 400W rated coolant pump delivers a rated flow rate of 3000L/H at 20M head and a maximum flow rate of 5000L/H with a 23M max lift, ensuring robust coolant circulation to efficiently dissipate heat from IGBT modules, capacitors, and other heat-generating components in wind turbine converters. Its compatibility with 50-60% glycol + water mixtures, dielectric oil, and electronic fluorinated solutions aligns with the cooling medium requirements of most wind turbine converter cooling systems, enabling seamless integration. The wide medium temperature range (-40℃ to 85℃) allows reliable operation in extreme outdoor environments, from cold plateaus to hot coastal wind farms. The 25mm outlet diameter ensures sufficient coolant delivery, while PWM speed regulation enables real-time flow adjustment to match the converter’s heat output during varying wind speeds and power generation loads. The high/low-level fault feedback signal provides instant operational status monitoring, facilitating timely maintenance and minimizing wind power generation downtime. With IP68 protection, robust safety features, and a long service life, the OWP-BL43-440T guarantees stable, durable performance, making it the optimal cooling solution to enhance the efficiency, reliability, and service life of wind turbine converters in the wind power industry.
