High Performance Electric Coolant Pump for Immersion-Cooled Data Center Systems
The OWP-BL43-200 Electric Coolant Pump is a high-performance single-stage centrifugal pump engineered for demanding immersion cooling systems in data centers. Equipped with a brushless DC motor and magnetic force transmission (shield pump structure), this pump delivers exceptional efficiency, reliability, and durability—making it ideal for maintaining optimal thermal conditions in mission-critical IT environments.
Key Advantages
Precision Flow Control: Features constant flow regulation to ensure stable coolant circulation, supporting consistent temperature management in immersion cooling tanks.
Comprehensive Protection Mechanisms: Integrated reverse polarity protection, dry running protection, over-voltage/over-current protection, and overload/over-temperature protection safeguard the pump and system from damage, minimizing downtime.
Superior Efficiency: Designed with professional electromagnetic theory verification, achieving 3-5% higher motor efficiency than industry competitors. Hydraulic simulation via specialized software optimizes impeller and volute matching for enhanced hydraulic performance.
Long Service Life: High-efficiency brushless DC motor with nylon plastic capsulated magnets ensures a service life exceeding 20,000 hours, reducing maintenance costs and replacement frequency.
Extreme Environment Resilience: Built with automotive-grade electronic components, the pump operates reliably in temperatures ranging from -40℃ to +85℃ (-40°F to +185°F) and withstands humidity up to 90%, adapting to harsh data center conditions.
IP68 Waterproof Rating: Fully sealed construction prevents water ingress, ensuring safe operation in immersion cooling setups where direct contact with coolants is required.
Low Noise Operation: Maintains noise levels ≤60dB, contributing to a quieter data center environment.

Data Center Immersion Cooling Application
The OWP-BL43-200 is specifically designed for immersion-cooled data center systems, where servers and IT hardware are submerged in dielectric coolant to dissipate heat efficiently. In these setups, the pump plays a critical role in circulating coolant throughout the immersion tank, transferring heat from high-density server racks to heat exchangers or cooling units. Its constant flow control ensures uniform cooling across all components, preventing hotspots and optimizing server performance. The pump's robust protection features and IP68 rating make it safe for long-term operation in coolant-filled environments, while its high efficiency and low power consumption align with data centers' sustainability goals. Whether deployed in large-scale cloud data centers or edge computing facilities, the OWP-BL43-200 delivers the reliability and performance needed to support 24/7 IT operations while reducing energy costs associated with cooling.
