Liquid Helium Pump

Designed for the Ultimate Cryogenic Challenge

 

The liquid helium pump is a specialized piece of equipment for transferring liquid helium at -269°C, a temperature just a few degrees above absolute zero. With the lowest boiling point and extremely low latent heat of vaporization, helium presents unique handling difficulties. This pump is used in critical applications such as cooling superconducting magnets, supplying large-scale scientific cryogenic systems, maintaining MRI equipment, and supporting aerospace engine ground tests.

The pump addresses the unique properties of helium through a purpose-built design. It uses a magnetic-drive or submersible configuration to eliminate dynamic seals, which are a primary leak path for such a highly penetrating fluid. All wetted components are manufactured from materials specifically validated for helium compatibility at -269°C. The design incorporates thermal isolation and anti-cavitation measures to maintain stable performance under these extreme operating conditions.

Flow rates for the liquid helium pump range from 0.5 m³/h to 100 m³/h, with heads up to 2,600 meters. This range allows for customization to meet the specific requirements of various applications, from large-scale research facilities to medical equipment maintenance. Each unit undergoes performance testing on our cryogenic test bench using liquid nitrogen as a surrogate medium. We can also develop custom test protocols based on your specific project needs.
