The OWP-BL43-426T Electronic Coolant Pump stands out as a critical component for electric truck battery thermal management systems. Electric trucks rely on large-capacity batteries to power long-haul trips, and these batteries generate significant heat during charging and operation. Excessive heat can degrade battery performance, shorten lifespan, and even pose safety risks. This pump addresses these challenges by efficiently circulating coolant through the battery pack, maintaining a stable operating temperature between -40℃ and +85℃—a range that ensures consistent battery output and long-term reliability. Whether navigating hot summer highways or cold winter roads, the pump’s robust design keeps the battery thermal management system running smoothly, supporting extended driving ranges and reducing downtime for battery maintenance. Beyond electric truck batteries, it also serves other high-demand applications like EV charging station cooling, fuel cell cooling, and data center immersion cooling, making it a versatile solution for thermal management needs.

1. Superior Efficiency: Designed and verified using professional electromagnetic theory, the pump’s motor delivers 3-5% higher efficiency than competitors, reducing energy consumption and lowering operational costs for electric truck fleets.
2. Optimized Hydraulic Performance: Professional software simulates and calculates the hydraulic design, ensuring the impeller and volute achieve the perfect match. This results in higher hydraulic efficiency, maximizing coolant flow and heat transfer capabilities.
3. Automotive-Grade Durability: Built with automotive-grade electronic components, the pump withstands extreme harsh operating environments—from temperature fluctuations to vibration—ensuring long-term durability in electric truck applications.

Equipped with advanced features like constant flow control, reverse polarity protection, dry running protection, and multiple overload/over-temperature safeguards, the OWP-BL43-426T ensures safe, reliable, and efficient operation—making it the top choice for electric truck battery thermal management and beyond.
