The OWP-BL93-201 Electric Coolant Pump is an advanced fluid circulation component engineered to meet the high-precision thermal management requirements of server CPU and GPU cold plate liquid cooling systems. Integrating permanent magnet brushless technology with optimized structural design, it delivers consistent and efficient fluid transfer, ensuring critical computing components maintain stable operating temperatures even under high-load conditions.

• Permanent Magnet BLDC Design: Boasts a compact profile and low power consumption, perfectly adapting to the space-limited server chassis while reducing overall energy consumption of the cooling system.
• Comprehensive Protection Systems: Equipped with reverse connection, overvoltage, overcurrent, dry running, and overtemperature protection mechanisms to safeguard both the pump and server components from operational abnormalities.
• Ultra-Durable Shaft Assembly: Adopts friction pair materials with exceptional service life for the shaft system, minimizing mechanical wear during prolonged operation and supporting the pump’s >20,000-hour lifespan.
• Centrifugal & Shielded Structure: Combines centrifugal pumping efficiency with a shielded design to prevent coolant leakage and isolate the motor from corrosive media, enhancing operational reliability.
• Lifetime Maintenance-Free Operation: Sealed construction and high-quality material selection eliminate the need for regular maintenance, reducing server downtime and operational costs.
• Closed Impeller Configuration: Features a precision-machined closed impeller that optimizes hydraulic efficiency, reduces energy loss, and maintains noise levels ≤45dB, ensuring quiet operation in server rooms.

Head-Flow Curve

The OWP-BL93-201 Electric Coolant Pump is specifically tailored for cold plate liquid cooling systems in server CPUs and GPUs. With a rated power of 100W, maximum flow rate of 2800L/H, and 11M lift head, it efficiently circulates cooling media to rapidly dissipate heat generated by high-performance computing components. Its compatibility with glycol-water mixtures, dielectric oil, and electronic fluorinated solutions, combined with a wide temperature range (-40℃ to 85℃), ensures stable operation in diverse server environments. The IP68 protection grade and compact size allow flexible installation within server chassis, while fixed-speed operation guarantees consistent coolant flow for reliable thermal management. This pump directly enhances server performance and longevity by preventing overheating, making it an ideal choice for data centers and high-performance computing facilities relying on CPU/GPU cold plate liquid cooling.
