Best Answer

Vacuum pumps are used in some processes where it is necessary to evacuate the air from a chamber before using it for some other material, or if it is necessary to remove all the oxygen. Partial vacuums are drawn in turbine condensers to extract as much energy from the low pressure stages as possible.
