Roughing pump: Overview, Related Topics & Entities

A roughing pump is any vacuum pump (typically mechanical) used to initially evacuate a vacuum system, as a first stage towards achieving high vacuum or ultra high vacuum. The term "roughing pump" derives from the vacuum range it works in, "rough vacuum", above 0.001 torr (0.1 Pa). Pumps that operate in the high vacuum ranges typically don't operate, or…
