Cryogenic Pump

cryogenic pump

[‚krī·ə′jen·ik ′pəmp]
A high-speed vacuum pump that can produce an extremely low vacuum and has a low power consumption; to reduce the pressure, gases are condensed on surfaces within an enclosure at extremely low temperatures, usually attained by using liquid helium or liquid or gaseous hydrogen. Also known as cryopump.

Cryogenic Pump


a condensate-removal or sorption vacuum pump whose pumping action is based on absorption of the gas being pumped by a surface cooled to extremely low temperatures (below 0.5°K). Cryogenic pumps provide a vacuum in a wide range, from 10−1 to 10−5 newtons per sq m.
