Industrial vacuum pump is special equipment that eliminates air from a sealed volume so as to offer a partial vacuum. It transforms the mechanical input energy of a rotating shaft into pneumatic energy by eliminating the air enclosed within the container. This leads to reduction in the internal pressure as compared to the external atmospheric pressure. The resultant energy generated always relies on the volume vacated as well as the pressure difference created. Apart from air these pumps also evacuate any gas in the container. These pumps have a vast domestic, commercial as well as industrial uses and their categories vary according to their usage.
