OWPD300LT-48-F50 High-Efficiency Brushless DC Pump: Key Details for Industrial & EV Cooling

The OWPD300LT-48-F50 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 Uses

Ideal for demanding cooling scenarios, it serves EV motor cooling, EV battery thermal management, high-power EV charging station cooling, and fuel cell cooling. It also excels in industrial applications: battery energy storage cooling, large-scale GPU cooling, immersion cooling for data centers, supercomputer cooling, communication base station cooling, and automotive antifreeze circulation. Additionally, it works as a glycol circulation booster, fluorinated liquid pump, and electric insulating oil booster.

Competitive Advantages
  1. 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.
  2. 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℃).
  3. Comprehensive Protection: Features reverse polarity, dry running, over-voltage/current, and over-temperature protection, plus speed regulation and fault feedback.
