PWM Speed Control & Fault Feedback

Key Technical Advantages
  1. Closed Impeller Design: The precision-machined closed impeller minimizes internal fluid leakage, achieving high pumping efficiency and reducing operational noise to ≤60dB—critical for maintaining quiet data center environments while maximizing heat transfer.
  2. Permanent Magnet Brushless Construction: Combines compact dimensions with low power consumption, fitting seamlessly into dense GPU server racks and reducing overall energy usage in data center cooling systems.
  3. Long-Life Shaft Assembly: Utilizes ultra-durable friction pair materials for the shaft system, supporting over 20,000 hours of continuous operation to match the long service cycles of data center hardware.
  4. Centrifugal & Shielded Structure: Isolates the motor from the cooling medium to prevent contamination and leakage, protecting sensitive GPU components from fluid damage and ensuring reliable, leak-free operation.
  5. PWM Duty Cycle Speed Regulation: Enables precise flow adjustment via PWM signals, allowing dynamic matching of cooling capacity to GPU heat output—optimizing energy efficiency during variable computing loads.
  6. Comprehensive Protection Mechanisms: Equipped with reverse polarity, overvoltage, overcurrent, dry running, and overtemperature protection, plus high/low-level fault feedback, ensuring system safety and enabling proactive maintenance.
Application in Data Center & AI Computing GPU Server Cooling

The OWP-BL43-450T Electric Coolant Pump is specifically tailored for GPU server thermal management in data centers and AI computing facilities, where sustained high-performance computing generates significant heat. Its 6000L/H rated flow rate (at 8M head) and 9000L/H maximum flow ensure efficient circulation of cooling media—including glycol-water mixtures, dielectric oil, and electronic fluorinated solutions—to rapidly dissipate GPU heat, preventing thermal throttling and maintaining computing stability. The 24VDC wide voltage input (18-32VDC) aligns with data center power standards, while the 38mm outlet diameter facilitates high-volume fluid transfer for multi-GPU server configurations. PWM speed regulation allows the pump to adapt to real-time heat loads, balancing cooling efficiency and energy consumption, while the IP68 rating and -40℃ to 85℃ temperature range ensure reliability in diverse data center environments. With fault feedback signals for intelligent monitoring, the OWP-BL43-450T serves as a critical component in GPU server cooling systems, supporting uninterrupted AI model training, high-performance computing, and data processing tasks.
