Designed exclusively for fuel cell cooling systems, the OWP-BL43-300 integrates multiple critical protections: constant flow control maintains consistent cooling performance, while reverse polarity protection prevents damage from incorrect wiring. Dry running protection safeguards the pump during low-liquid conditions, and comprehensive overvoltage, overcurrent, overload, and overtemperature protections ensure durability in harsh operating scenarios.
As a single-stage centrifugal pump with a magnetic force transmission (shield pump structure), it eliminates leakage risks—critical for fuel cell systems where fluid integrity is paramount. The high-efficiency brushless DC motor not only reduces power consumption but also delivers a service life exceeding 20,000 hours, minimizing maintenance needs for long-term operation. With a wide operating temperature range and PWM speed control, the pump adapts seamlessly to dynamic fuel cell load changes, optimizing cooling efficiency and system performance.
