What Is The Difference Between Ejector And Vacuum Pump?

- Dec 23, 2017 -

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 and a vane chamber or a liquid ring chamber evacuate air from a specific area. 

I.e, ejectors use compressed air to generate vacuum and pumps use electricity to generate vacuum. 

In terms of end applications ejectors are used for low vacuum level low flow rate applications and pumps are used for high vacuum high flow rate applications. Pumps may also be preferred for higher efficiencies or clean room applications.
