How do Rotary Vane pumps work?
Rotary vane pumps work by having a rotor with two adjusting vanes continuously rotating and exhausting air or any other molecules in the occupied space. The four stages which a rotary vane pump undergo are shown below
Single Stage vs Two Stage Vacuum Pump:
BVV™ Pro Series pumps are a dual-stage rotary vane pump style. Dual-stage pumps have two rotors and two sets of vanes that work together to fully pull a medium vacuum (1st stage) and then pull a better vacuum (2nd stage). These pumps will evacuate more quickly and can pull a deeper vacuum when compared to single-stage pumps.
What is Gas Ballast and how does it work?
During the pumping process the vacuum pump is trying to evacuate gas present in the occupied space, both non-condensable and condensable gases and vapors. Gas ballast helps increase the percentage of non-condensable vapors such that it will allow for the pump to efficiently exhaust all gases and vapors. This in turn will increase the overall efficiency and pumps life. When the pump is being used with non-condensable gases it's safe to keep the gas ballast valve closed. On the other hand, when there is a condensable gas or vapor present, the gas ballast should be opened appropriately. Gas ballast is used at the beginning of the pumping process when condensable gases are known to be present, then it's closed to finish pulling the deepest vacuum.
