The three types of pump systems: positive displacement, momentum transfer, and entrapment.

Positive displacement: Uses 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. Ex: rotary and screw pumps

Rotary: [[File:rotarypump.jpg]]

Screw: [[File:screwpump.jpg]]

Momentum transfer: Uses high speed jets of dense fluid or high speed rotating blades to knock gas molecules out of the chamber. Ex: Diffusion and turbo molecular

Diffusion: [[File:diffusionpump.png]]

Turbo molecular: [[File:Cut_through_turbomolecular_pump.jpg]]

Entrapment: capture gases in a solid or adsorbed state. Ex: Ion and sorption pumps

Ion: [[File:ionpump.jpg]]

Sorption: [[File:sorptionpump.gif]]
