Automotive Water Pump OWPD250LQ-24-P38 High Capacity and Quality for HEV Buses Battery Cooling
The OWPD250LQ-24-P38 Electric Water Pump is a high-performance, durable solution engineered for precise liquid circulation, ideal for demanding cooling and thermal management needs. Its core working principle relies on a single-stage centrifugal design paired with magnetic force transmission (shield pump structure), which eliminates leakage risks while ensuring efficient fluid transfer. Powered by a high-efficiency brushless DC (BLDC) motor, it uses PWM speed control to adjust flow dynamically, and integrates multi-layer protections—including reverse polarity, dry running, over-voltage, over-current, overload, and over-temperature safeguards—to ensure stable operation even in harsh conditions.
