Vacuum pumps can be defined as devices that move air into or out of something to create a vacuum. Vacuum pumps can be designed to pump gas as well as liquid. Therefore at times vacuum pumps are used to remove water from one place to the other or remove gas from an area leaving a partial vacuum behind. Therefore vacuum pumps are used for varied purposes. Vacuum pumps are quite often used in industrial settings as well where there is a need to process semiconductors and produce vacuum tubes and electric lamps.
The classification of vacuum pumps depends upon the use of the vacuum pump. The vacuum created by the pump can be used to evacuate a condenser, prime a centrifugal pump or lower the pressure in a chemical vessel. Therefore there are many uses of the vacuum pumps and the capacity needed, along with how much pressure and how much vacuum needed will dictate the type of vacuum pump needed.
Broadly there are two types of vacuum pumps; entrapment pumps and transfer pumps. Entrapment pumps trap the liquefied gas molecules or ionized gas molecules. The transfer pumps accelerate gas from the vacuum side to the exhaust side by using momentum. Another classification is the mechanical pump and the compressed air vacuum pump.
