This electric coolant pump is specifically designed to address the intense heat management challenges of AI Clusters. In AI training rigs, where dozens to hundreds of GPUs operate continuously at full load, the pump’s high flow rate (up to 5000L/H) and stable pressure ensure consistent coolant circulation, preventing GPU throttling and safeguarding long-term training efficiency. For Data Centers, which host dense server racks with integrated GPUs for cloud computing, big data analytics, and cloud gaming, the pump’s IP68 waterproof rating and wide operating temperature range (-40℃ to +85℃) make it suitable for 24/7 operation in harsh, high-humidity environments. It seamlessly integrates with liquid cooling systems to maintain server stability, reducing energy consumption compared to traditional air cooling. In HPC facilities, used for complex scientific simulations (e.g., weather forecasting, aerospace modeling) and quantum computing, the pump’s durable construction (including SUS 304 stainless steel fasteners and aluminum housing) and magnetic force transmission (shield pump structure) ensure leak-free, low-maintenance performance. Its ability to handle multiple coolant types (such as glycol-water mixtures and dielectric oils) adapts to the diverse cooling needs of HPC GPU clusters, supporting uninterrupted, high-precision computing tasks.
The OWP-BL43-426C stands out with multiple protective features, including reverse polarity protection, dry running protection, and over-voltage/over-current/over-temperature protection, minimizing equipment damage risks. Its constant flow control and PWM speed regulation allow for precise adjustment to match varying GPU heat loads, optimizing energy efficiency. The high-efficiency brushless DC motor delivers a long service life (over 20000 hours) and low noise (≤60dB), enhancing operational sustainability and reducing workplace noise pollution. Additionally, the flange quick-connect design enables easy installation and maintenance, saving time for technicians in large-scale cooling system deployments.
