The OWP-BL43-426T Electronic Coolant Pump is a high-performance solution designed to excel in antifreeze circulation scenarios, ensuring reliable thermal management across diverse industrial and automotive applications.

In antifreeze circulation, this pump plays a critical role in maintaining optimal temperatures for sensitive systems. It is widely used in EV battery thermal management, where it circulates antifreeze to prevent overheating or freezing of battery packs—critical for preserving battery life and ensuring safe operation in extreme temperatures ranging from -40℃ to +85℃. Additionally, it supports electric truck power battery thermal management systems, keeping antifreeze flowing steadily to protect batteries during heavy-duty use. For fuel cell cooling, the pump circulates antifreeze to regulate fuel cell temperatures, enhancing efficiency and durability. It also serves high-power EV charging stations and liquid-cooled superchargers, where antifreeze circulation prevents overheating during rapid charging. Beyond automotive uses, it aids in data center immersion cooling by circulating antifreeze (or compatible coolants) to maintain stable temperatures for high-density servers, and supports battery energy storage cooling to safeguard stored energy systems.

1. Superior Efficiency: Professional electromagnetic theory design boosts motor efficiency by 3-5% compared to competitors, while advanced hydraulic simulation (via professional software) optimizes impeller-volute matching for higher hydraulic efficiency—reducing energy consumption and lowering operational costs.
2. Extreme Durability: Automotive-grade electronic components enable the pump to withstand harsh operating environments, from extreme temperatures (-40℃ to +85℃) to moisture and dust (IP68 rating). A high-efficiency brushless DC motor ensures a long service life of over 20,000 hours.
3. Enhanced Safety: Equipped with multiple protections (reverse polarity, dry running, over-voltage, over-current, overload, over-temperature) and a magnetic force transmission (shield pump structure), it prevents leaks and ensures safe, uninterrupted operation.
