Liquid Cooling Pumps for Data Center Servers

Delivering Advanced Liquid Cooling Pump and Drive Systems

Moog’s CoreMotion™ magnetic pump with matching drive is designed for pumping coolant in direct-to-chip and immersion liquid cooling applications for heat removal. By integrating the rotor magnetics and the impeller into a single piece, our designs minimize the pump size and eliminate rotating seals, resulting in more compact pumps with fewer leak points. Moog’s CoreMotion™ pumps are paving the way for data center cooling solutions.

The Importance of Data Center Cooling Pumps: Essential for Efficient Operation

As technology continues to evolve, the demand for efficient, high-performance data centers has never been greater. With an increasing number of servers, higher computing power, and constant data flow, managing heat in data centers has become one of the most critical aspects of operations. This is where Moog’s CoreMotion™ magnetic data center cooling pump comes into play. 

 

The Benefits of Liquid Cooling

Liquid cooling significantly improves Power Usage Effectiveness (PUE) by reducing the energy required to cool data centers, leading to lower operational costs and a smaller carbon footprint. Unlike traditional air cooling, liquid cooling efficiently absorbs and dissipates heat directly from high-performance IT equipment, minimizing thermal resistance and reducing the need for energy-intensive air conditioning.  

Advanced solutions like Moog’s CoreMotion™ pumps further enhance PUE by integrating high-efficiency direct-drive motors, variable-speed control, and seal-less magnetic space saving designs, which eliminate unnecessary energy losses and optimize coolant flow in real-time. By utilizing wet rotor designs and using eco-friendly materials and fluids, these systems not only improve cooling efficiency but also contribute to a sustainable, greener data center infrastructure. As a result, organizations can achieve a lower PUE ratio, ensuring greater energy efficiency, reduced costs, and improved hardware longevity all while maintaining performance supporting global sustainability initiatives.
