The OWP-BL43-300 Electric Coolant Pump is a high-performance, durable cooling component specifically engineered for battery energy storage cooling—with a primary focus on mobile energy storage cabinet liquid cooling systems. As mobile energy storage solutions increasingly demand high power density and reliable operation in harsh environments, this pump delivers consistent thermal management to protect battery cells, extend service life, and ensure stable performance. It efficiently circulates cooling fluid in liquid cooling loops, maintaining optimal cell temperatures (even during long-term high-load operation) to prevent overheating, reduce capacity degradation, and enhance the safety of mobile energy storage cabinets used in emergency power supply, temporary event power, renewable energy grid integration, and outdoor/offshore deployment.

1. Superior Efficiency: Verified through professional electromagnetic theory design, the pump motor achieves 3-5% higher efficiency than industry competitors. Its hydraulic system—optimized via professional software simulation—ensures perfect matching between the impeller and volute, delivering exceptional hydraulic efficiency.
2. Extreme Durability & Reliability: Built with automotive-grade electronic components, the pump withstands harsh operating conditions (from -40℃ to +85℃) and boasts an IP68 rating for complete protection against dust and water. The brushless DC motor ensures a service life exceeding 20,000 hours, reducing maintenance costs.
3. Comprehensive Protection & Flexibility: Equipped with multiple protection mechanisms (reverse polarity, dry running, over-voltage, etc.) and PWM speed regulation, it adapts to dynamic cooling demands. The fault feedback signal enables real-time system monitoring, enhancing operational safety.
4. Quiet & Compact Design: With noise control ≤60dB, it operates quietly without disrupting surrounding environments. The aluminum housing combines lightweight construction with robust performance, ideal for mobile energy storage cabinets requiring space-saving and durable components.
