The OWP-BL400H-D2-21 stainless steel coolant pump is a high-performance solution tailored for AI computing center liquid cooling equipment—a critical application where stable heat dissipation directly impacts computing efficiency and hardware longevity. Beyond AI centers, it also serves data center server liquid cooling, electric vehicle charging station cooling, and small marine engine cooling, making it a versatile choice for industrial thermal management needs.

• Exceptional Durability: With a stainless steel water-contacting component and an IP68 protection rating, the pump resists corrosion and dust, ensuring reliable operation in harsh environments. Its working lifespan exceeds 20,000 hours, minimizing maintenance frequency and costs.
• Stable & Safe Performance: Equipped with multi-layer protection (reverse connection, no-load, locked-rotor, over-voltage, and under-voltage protection), it prevents damage from abnormal conditions. The PWM speed control function allows precise adjustment of flow rates to match dynamic cooling demands of AI servers.
• High Efficiency & Low Noise: Delivering a rated power of 400W ±5%, it achieves a flow rate of 3000L/h with a head ≥20m, ensuring efficient heat transfer. At 1m distance, the load noise is ≤60dB(A), maintaining a quiet working environment in AI facilities.
• Robust Environmental Adaptability: It operates seamlessly in temperatures ranging from -40℃ to 85℃ (both for the environment and coolant) with relative humidity ≤90%, adapting to extreme climate conditions. The flange quick-connect inlet/outlet design enables fast installation and replacement.

This pump’s combination of efficiency, safety, and versatility makes it a top choice for AI computing centers seeking to optimize thermal management and ensure uninterrupted operation of high-density computing hardware.
