Flojet liquid cooling pumps

To handle the intense thermal output of today's high-performance computing, you need a robust liquid cooling system proven to protect critical components. When failure is not an option, Flojet D5, DDC and diaphragm pumps keep that coolant flowing. With their proven reliability and quiet operation, the compact D5 and DDC pumps were the first purpose-built direct liquid cooling (DLC) pumps in the world, and today they continue to set the standard for efficient, long-lasting liquid cooling performance. For larger CDUs in enterprise applications, Flojet diaphragm pumps accommodate an extensive range of flow rates and pressure limits in compact footprints – ideal for glycol charging and top-up in data center cooling systems.

Proven reliability

With an expected service life of well over 50,000 hours, the Flojet D5 and DDC are designed to go the distance – and have for over 25 years. Their shaftless ball motor and self-adjusting bearing make these pumps maintenance-free.

Industry-focused flow performance

Despite a remarkably small footprint, the D5 and the DDC pumps feature up to an astounding 145 PSI (10 bar) of system pressure to provide superior and consistent flow rates in even a more complex liquid-cooled system.

Quiet operation

Designed to deliver the perfect balance of power and silence, the Flojet D5 and DDC pumps utilize brushless motors and are lubricated directly by the coolant for ultra-quiet performance.

Compact design

The design of the D5 and DDC pumps save space and fit with the corresponding Enterprise reservoirs from chassis as small as a 1U server rack. This results in a powerful pump that can be used in the tightest of spaces within a server room or small data center.

Global service network

With a global network of manufacturing facilities, customer service offices, and design and engineering centers, Xylem provides a full range of R&D and sales support.
