A Rotary vacuum pump functions by compressing and pushing out the air mechanically from inlet to outlet. Hence, the outlet pressure has to be higher than atmospheric pressure for exhaust to take place. In two stages rotary pump the outlet of one chamber is attached to the inlet of next chamber. This increases the compression and makes the air exhaust possible.
