The new CoreMotion CM400 and CM28 canned centrifugal pumps are designed for cooling distribution units (CDUs), addressing both cooling capacity and energy efficiency as rack power densities continue to increase.

As data centers deploy increasingly powerful processors, the power required to circulate liquid coolant becomes another factor in overall cooling efficiency. Moog's new pumps are designed to deliver the flow rates and pressures required for high-density liquid cooling while reducing maintenance requirements and potential coolant leakage.

The larger CM400 targets end-of-row CDU installations. Weighing 399 pounds (181 kg), the pump has a 37 kW electrical power rating, supports flow rates of 250 to 500 gallons per minute (GPM), and operates at pressures ranging from 25 to 112 PSI.

The smaller CM28 is intended for in-rack CDU applications. Weighing 16.9 pounds (7.7 kg), the unit has a 2.8 kW electrical power rating and supports flow rates up to 55.5 GPM, with a maximum pressure capacity of 72.5 PSI.

Both pumps feature Moog's integrated drive and canned-pump architecture, which combines the rotor magnetics and impeller into a single assembly. The seal-less design eliminates conventional rotating shaft seals, reducing potential leak paths and associated maintenance requirements.

According to Moog, the architecture also simplifies integration for CDU manufacturers and supports applications in both new high-density installations and existing data centers being retrofitted for liquid cooling.

Axel Bokiba, general manager of Data Center Cooling at Moog, said the company developed the new pumps to address increasing processor thermal design power and the resulting demands on liquid cooling infrastructure.

Moog manufactures its pumps in the United States and says its integrated manufacturing approach allows it to support the evolving requirements of CDU manufacturers.

The company will demonstrate the CM400 and CM28 at booth 4547 during SC26, including their application in cooling systems designed around the Deschutes 5.0 CDU specification.
