How it works: Cryopump technology - Leybold
WEBAug 26, 2020 · Cryopumps are more efficient than other pumps used for similar applications. Unlike gas transfer pumps (like turbomolecular pumps or oil diffusion pumps), cryopumps condense all gasses within them. Installers can mount cryopumps in …
Cryopump - Wikipedia
WEBA cryopump or a "cryogenic pump" is a vacuum pump that traps gases and vapours by condensing them on a cold surface, but are only effective on some gases. The effectiveness depends on the freezing and boiling points of the gas …
WEBThe Cryo-Torr Pump provides fast, clean pumping of all gases in the 10-3 to 10-9 Torr range. The cryopump operates on the principle that gases can be condensed and held at extremely low vapor pressures, achieving high speeds and throughputs, as described in Table 1-1 - Table 1-11.
WEBThis report introduces the wide field of cryogenic pumping, from commercial cryogen-free refrigerator cryopumps to very special, tailor-made cryopumps. It starts with a short historic overview of the field of cryopumping. Then, the principles of cryogenic pumping via sublimation/condensation and physisorp tion are introduced, and we illustrate

WEBA cryopump is vacuum pump that traps gases and vapors by condensing them on a cold surface. For efficient evacuation under ultra-high vacuum, the vapor pressure for condensation, or the equilibrium pressure for adsorption must be less than 10-8 Pa. Figure 1 shows vapor pressures of different gases.

WEBA cryopump has many of the same characteristics of space atmo-sphere. It operates over a wide range of pressures, provides a clean vacuum and captures gases by freezing them out. As the gases are frozen, they are unable to return to …
Understanding the Working Mechanism of a Cryopump - Provac
WEBJul 29, 2022 · Cryopumps use a cryogenic pump head to remove gasses from a system. The pump head works by condensing the gas onto a cold surface, usually made of metal. The gas is then drawn into the pump body by a vacuum, and the cycle repeats.
