The OWP-BL43-300 Electric Coolant Pump is a professional-grade fluid circulation device engineered to meet the rigorous heat dissipation needs of high-density computing systems, with a primary focus on supercomputer liquid cooling applications. It integrates advanced protection mechanisms, energy-efficient operation, and robust durability, making it a reliable core component for maintaining stable thermal conditions in supercomputing clusters.

Equipped with a single-stage centrifugal structure and magnetic force transmission (shielded pump design), the OWP-BL43-300 eliminates leakage risks while ensuring smooth fluid flow. It offers comprehensive protection functions, including constant flow control, reverse polarity protection, dry running protection, and safeguards against over-voltage, over-current, overload, and over-temperature—critical for preventing pump damage in the high-stress environment of supercomputer cooling loops. The brushless DC motor further enhances performance with high efficiency, low power consumption, and an extended service life exceeding 20,000 hours.

Supercomputers generate massive heat due to their high-density CPU/GPU clusters, and liquid cooling systems (e.g., cold plate or immersion cooling) are essential for efficient heat removal. The OWP-BL43-300 plays a pivotal role in these systems by circulating coolant (such as water-glycol mixtures or dielectric fluids) to absorb heat from critical components like CPUs and GPUs. Its wide operating temperature range (-40℃ to +85℃) adapts to the extreme thermal fluctuations of supercomputer environments, while the IP68 rating ensures safe operation even in damp or dusty server rooms. The PWM speed control allows dynamic adjustment of coolant flow based on real-time heat loads—for example, increasing flow during peak computing tasks to enhance heat dissipation, or reducing flow during low-load periods to save energy. With a maximum flow rate of 9000L/H and 10M lift head, it efficiently distributes coolant across large cooling loops, ensuring uniform heat removal and preventing localized hotspots that could degrade supercomputer performance or cause hardware failure. This reliability makes it an indispensable component for maintaining the continuous, high-performance operation of supercomputing facilities.

1. Higher Motor Efficiency: Verified through professional electromagnetic theory design, the pump’s motor delivers 3-5% higher efficiency than competitors, reducing energy consumption in long-term supercomputer operation and lowering overall operational costs for data centers.
2. Optimized Hydraulic Performance: Professional software simulates and optimizes the impeller and volute design, achieving better hydraulic efficiency that ensures faster, more consistent coolant circulation—critical for handling the high heat loads of supercomputer clusters.
3. Automotive-Grade Durability: Built with automotive-grade electronic components, the pump withstands extreme harsh conditions (e.g., temperature spikes, voltage fluctuations) common in supercomputer centers, minimizing downtime and extending the lifespan of cooling systems.

Ideal for supercomputer liquid cooling systems, the OWP-BL43-300 balances performance, durability, and energy efficiency, making it a top choice for data center operators and supercomputing facilities seeking to enhance thermal management and operational reliability.
