Pumps can typically categorized into one of three broad categories (as per wikipedia):
- Positive displacement pumps use a mechanism to repeatedly expand a cavity, allow gases to flow in from the chamber, seal off the cavity, and exhaust it to the atmosphere.
- Momentum transfer pumps, also called molecular pumps, use high speed jets of dense fluid or high speed rotating blades to knock gas molecules out of the chamber.
- Entrapment pumps capture gases in a solid or adsorbed state. This includes cryopumps, getters, and ion pumps.
