Product Description
OWP-BL300H-D3-3 High-Efficiency Brushless DC Pump
Electric Coolant Pump for Coolant Circulation System, with 48 VDC Input and PWM speed Regulation
Product Description
The OWP-BL300H-D3-3 is a high-performance brushless DC (BLDC) pump designed for reliable liquid circulation, leveraging magnetic force transmission (shield pump structure) and a single-stage centrifugal design. Its working principle involves a nylon plastic-encapsulated magnet driving the impeller—optimized via professional hydraulic simulation software—to ensure efficient fluid movement, while the IP68 waterproof BLDC motor minimizes power loss and extends lifespan.
Core Applications
Ideal for demanding cooling scenarios, including:
- EV motor cooling and EV battery thermal management
- High-power EV charging station cooling and fuel cell cooling
- Industrial applications: battery energy storage cooling, large-scale GPU cooling
- Immersion cooling for data centers and supercomputer cooling
- Communication base station cooling and automotive antifreeze circulation
- Glycol circulation booster, fluorinated liquid pump, and electric insulating oil booster
Competitive Advantages
- Higher Efficiency: Motor efficiency is 3-5% greater than competitors, thanks to verified electromagnetic design; hydraulic efficiency is enhanced by perfectly matched impellers and volutes.
- Extreme Durability: Automotive-grade components withstand harsh environments, with a service life exceeding 20,000 hours (up to 40,000 hours for the BLDC motor) and wide temperature tolerance (-40℃ to +85℃).
- Comprehensive Protection: Features reverse polarity, dry running, over-voltage/current, and over-temperature protection, plus speed regulation and fault feedback.
