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.
