Application & Usage
The OWP-BL43-440T High-Efficiency Brushless DC Electric Coolant Pump is primarily designed for electric excavator motor cooling in the construction machinery industry, where stable thermal management is crucial for operational safety and efficiency. Electric excavators operate under extreme conditions including heavy loads, continuous operation, and exposure to temperature fluctuations ranging from -40℃ to 85℃.
This pump's compatibility with multiple media (glycol-water mixtures, dielectric oil, electronic fluorinated solutions) makes it adaptable to different cooling system configurations. With a rated flow rate of 3000L/H (at 20M head) and maximum flow of 5000L/H, it efficiently circulates cooling media to dissipate heat generated by electric excavator motors during high-intensity operations.
