When it comes to reliable temperature management in Lithium-ion Battery Energy Storage Systems (BESS), the OWP-BL43-440C Electric Coolant Pump stands out as a high-performance, durable solution engineered to meet the rigorous demands of energy storage applications. Combining advanced BLDC motor technology, precision hydraulic design, and comprehensive protection features, this pump ensures optimal thermal regulation, extending battery life and enhancing system safety.
The OWP-BL43-440C is designed with innovation and reliability at its core. Equipped with constant flow control and PWM speed regulation, it offers flexible performance adjustment to adapt to dynamic cooling needs in BESS operations. Its magnetic force transmission (shield pump structure) eliminates leakage risks, while the high-efficiency BLDC motor—validated through professional electromagnetic theory design—delivers a 3-5% higher efficiency rating compared to industry competitors, reducing energy consumption and operational costs.
Hydraulic efficiency is optimized via professional software simulation, ensuring the impeller and volute achieve perfect matching for maximum fluid dynamics. Safety is prioritized with a full suite of protections: reverse polarity protection, dry running protection, over-voltage/over-current protection, and overload/over-temperature protection, safeguarding both the pump and the entire energy storage system from potential failures. With an IP68 waterproof rating and noise control ≤60dB, it operates seamlessly in harsh environments while maintaining a quiet performance.

Lithium-ion batteries in energy storage systems generate significant heat during charging, discharging, and long-term operation. Excessive temperature fluctuations or overheating can degrade battery performance, reduce cycle life, and pose safety hazards such as thermal runaway. The OWP-BL43-440C is specifically engineered to address these challenges, providing consistent, efficient cooling for BESS installations.
With a wide operating temperature range of -40℃ to +85℃ for the cooling medium and -40℃ to +120℃ for the ambient environment, this pump thrives in extreme conditions—from cold outdoor energy storage farms to high-temperature industrial facilities. Its high flow rate (up to 4600L/H) and maximum lift head (23M) ensure rapid heat dissipation across large battery packs, while PWM speed regulation allows real-time adjustment based on temperature changes, optimizing energy efficiency.
The pump’s robust construction, including IP68 waterproofing and corrosion-resistant components, ensures durability in demanding BESS environments. Whether used in utility-scale energy storage systems, commercial backup power solutions, or residential battery banks, the OWP-BL43-440C delivers reliable, long-lasting cooling performance (＞20000 hours service life) that protects battery investments and ensures uninterrupted energy supply.
