Small-Scale Scroll Cryogenic Pump

Compact, reliable, light-weight, and electrically-driven scroll, capable of pumping volatile liquids at extremely low temperatures.

Developed for NASA, the pump is designed to move low-temperature liquids efficiently in zero gravitycryogenic control devices. With numerous aerospace applications, the design can be used as a fuel pump for liquid hydrogen-fueled aircraft.

The scroll pump was developed as part of a Phase I Small Business Innovation Research grant (SBIR). The SBIR asked for the design, fabrication, and testing of the world’s first small-scale positive displacement cryogenic pump. The SBIR was awarded to Air Squared on April 1, 2013, with Phase I completion on November 23, 2013.
