What is the difference between ejector and vacuum pump

Answer (1 of 4): Ejectors are basically venturies where you pump compressed air on one side and using the venturi principle evacuate air from a perpendicular orfice situated a little after the venturi neck. Vacuum pumps are of many varieties. The basic idea of a pump is using an electric motor

Vacuum Ejectors - Schmalz

Compact ejectors have an integrated air-saving regulation. This function interrupts vacuum generation as soon as a safe vacuum value has been reached. Vacuum generation is switched back on only once the value falls below the preset minimum vacuum value. Compact ejectors with an air-saving regulation use far less compressed air than a
