24VDC Electronic Coolant Pump Using for Cold Plates GPUs/HPC Cooling

BLDC Coolant Pump (OWP-BL43-426C): Specifications, Advantages & Applications

The BLDC Coolant Pump (Model: OWP-BL43-426C) is a high-performance, durable solution designed for precise thermal management, with a primary focus on cooling cold plates that directly contact heat-intensive components like GPUs and CPUs. This application is critical in industries such as high-performance computing (HPC), data centers, gaming PCs, and industrial automation—where maintaining stable temperatures of GPUs/CPUs prevents overheating, ensures consistent performance, and extends the lifespan of expensive electronic equipment. Beyond cold plate cooling, the pump’s compatibility with diverse media (glycol-water mixtures, dielectric oil, mineral oil, electronic fluorinated solutions) also makes it suitable for specialized thermal systems in automotive electronics, renewable energy inverters, and medical equipment.

Key Advantages

This BLDC coolant pump stands out for its robust protection, efficiency, and reliability:

  • Comprehensive Protection: Equipped with reverse polarity protection, dry running protection, and safeguards against over-voltage, over-current, overload, and over-temperature—minimizing damage risks and ensuring safe operation in harsh conditions.
  • High Efficiency & Long Lifespan: Features a brushless DC motor with over 20,000 hours of service life, delivering low power consumption (240W rated power) and high operational efficiency, reducing energy costs and maintenance frequency.
  • Precise Control: Supports PWM speed regulation for adjustable flow rates, paired with constant flow control to maintain stable cooling performance even under fluctuating system demands.
  • Superior Durability & Waterproofing: Boasts an IP68 waterproof rating (per EN60529) for resistance to dust and water immersion, while components like SUS 304 stainless steel screws/nuts and aluminum pump housing enhance corrosion resistance and structural strength.
  • Quiet Operation: Noise levels are controlled to ≤60dB, making it ideal for noise-sensitive environments like office-based data centers or indoor industrial setups.
