5.5 rotary pump working principle and types
Vane pumps work by creating a vacuum that draws the fluid into the pump. The rotor with sliding vanes traps the fluid between the rotor and the casing. As the rotor rotates, the vanes slide in and out, creating a vacuum that draws the fluid into the pump. The flow rate of the pump is proportional to the size of the vanes and the speed of rotation.

What is a Sliding Vane Pump?
A sliding vane pump is a common type of hydraulic pump used to convert mechanical energy into the flow of liquid. Its working principle is based on one or more vanes (also known as blades, wings, or vanes) sliding within the rotor of the pump as it rotates, thereby generating the pumping effect for liquids.

Rotary Vane Vacuum Pumps
Rotary vane pumps, aside from being positive displacement pumps, can be constructed as dry pumps or oil-sealed pumps. In a nutshell, dry pumps operate without the usage of any liquid. Wet pumps use a fluid seal/lubrication to work, while dry pumps depend on internal dimensional tolerance to make a vacuum.
