A rotary vane pump works using positive displacement. It is made up of a series of vanes mounted within a rotor. This provides circulation within the main cavity, making it possible to force air through a pipe, duct or process at varying rates based on the application. Or, pull the air into or through a process when vacuum is required.
When in operation, the vanes slide in and out, creating a seal around the cavity or chamber, and allowing a series of smaller chambers to form within the larger chamber. Inside each chamber, air is captured and compressed, forcing it through the system, which is caused by the increasing or decreasing sizes of the chambers between the vanes, while rotating.
The rotor supports the continuous flow of air in a uniform manner during the process, and does this without any of the “Pulsations” that most other technologies of pump create.
A rotary vane pump can be used for either vacuum or pressure, and sometimes both!
