OWP-BL43-440C Electric Coolant Pump: Premium Cooling Solution for High-Power EV Charging Stations
Engineered for extreme reliability in demanding electric vehicle (EV) infrastructure, the OWP-BL43-440C Electric Coolant Pump delivers industry-leading performance for high-power charging stations, battery swap facilities, and critical cooling systems. Combining advanced BLDC motor technology with robust magnetic transmission, this single-stage centrifugal pump ensures stable, efficient thermal management even in harsh operating environments.
Core Advantages
Designed to outperform standard cooling pumps, the OWP-BL43-440C integrates multiple protective features and efficiency-boosting technologies:
Precision Flow Control: Equipped with constant flow regulation and PWM speed adjustment, the pump adapts dynamically to cooling demands, optimizing energy consumption while maintaining consistent thermal performance.
Comprehensive Protection Systems: Features reverse polarity protection, dry running safeguard, and multi-layered protection against overvoltage, overcurrent, overload, and overtemperature—ensuring uninterrupted operation and extended service life (＞20,000 hours).
Enhanced Efficiency: Professional electromagnetic design verification enhances motor efficiency by 3-5% compared to competitors, while hydraulic simulation-optimized impeller and volute configurations maximize fluid dynamics for superior hydraulic efficiency.
Robust Construction: Magnetic force transmission (shield pump structure) eliminates leakage risks, while the nylon plastic-encapsulated driving magnet ensures corrosion resistance and long-term reliability. With an IP68 rating, the pump operates seamlessly in dust, moisture, and extreme temperatures (-40℃ to +120℃ ambient).
Wide Operational Range: Handles medium temperatures from -40℃ to +85℃ and system pressures between -0.5 to 2.5 Bar, making it suitable for diverse cooling media in EV charging applications.
