Core Features & Advantages
  • High-efficiency brushless DC motor with service life exceeding 20,000 hours
  • Magnetic force transmission (shield pump structure) eliminates leakage risks
  • Comprehensive protection mechanisms: constant flow control, reverse polarity protection, dry running protection, over-voltage/over-current protection, and overload/over-temperature protection
  • Professional electromagnetic theory design verification boosts motor efficiency by 3-5% compared to competitors
  • Advanced hydraulic design simulation optimizes impeller and volute matching for higher hydraulic efficiency
  • Automotive-grade electronic components withstand extreme temperatures, vibrations, and harsh operating conditions
Applications: Focus on Energy Storage & Large EV BMS
In energy storage systems (ESS), the OWP-BL43-300 plays a critical role in regulating battery temperature during charging and discharging cycles. Consistent thermal management prevents overheating, extends battery lifespan, and maintains system efficiency—even in high-density energy storage setups. For large electric vehicles (such as commercial EVs, buses, and heavy-duty trucks), the pump ensures uniform cooling of high-capacity battery packs, addressing the thermal challenges of long-distance travel and frequent charging. By maintaining optimal battery temperatures, the pump enhances driving safety, improves energy utilization, and supports the reliable operation of BMS in high-demand scenarios. Whether for grid-scale energy storage or industrial-grade EVs, the OWP-BL43-300 delivers the performance, durability, and efficiency required for mission-critical thermal management.
