Designed exclusively for hydrogen fuel cell vehicle cooling systems, the OWP-BL43-426C Electric Coolant Pump delivers reliable, high-performance coolant circulation to maintain optimal operating temperatures of fuel cell stacks. Its robust build, advanced protection features, and wide adaptability to extreme conditions make it a critical component for ensuring the efficiency, safety, and longevity of hydrogen fuel cell vehicles (FCEVs).

Hydrogen fuel cell stacks generate significant heat during operation, and maintaining their temperature within the -40℃ to +85℃ range is vital to avoid performance degradation or component damage. The OWP-BL43-426C pump addresses this need by:

• Circulating coolants (e.g., glycol-water mixtures) efficiently through the fuel cell cooling loop, ensuring uniform heat distribution and rapid heat dissipation.
• Adapting to dynamic FCEV working conditions: Its PWM speed control adjusts flow rate in real time—boosting circulation during high-load scenarios (e.g., acceleration, uphill driving) and optimizing energy use during low-load operation (e.g., idling, cruising).
• Withstanding harsh automotive environments: IP68 waterproofing protects against water, dust, and vibration, while its -40℃ to +85℃ operating temperature range suits extreme climates (from cold winters to hot summers).

1. Comprehensive Protection for Safety & Durability: Equipped with reverse polarity protection, dry running protection, and safeguards against over-voltage, over-current, overload, and over-temperature—preventing pump damage and ensuring FCEV cooling system stability.
2. High Efficiency & Long Lifespan: The brushless DC motor reduces power consumption while delivering high efficiency, and its magnetic force transmission (shield pump structure) minimizes wear, enabling a service life of over 20,000 hours.
3. Constant Flow & Reliability: Constant flow control maintains consistent coolant circulation, avoiding temperature fluctuations that could harm fuel cell performance.
4. Easy Integration: Flange quick-connect design and compatible AMP connectors simplify installation into existing FCEV cooling systems, reducing assembly time and costs.

Ideal for FCEV manufacturers and aftermarket suppliers, this pump ensures seamless, long-term cooling performance—supporting the reliability and sustainability of hydrogen fuel cell vehicles.
