Rotary vane pumps consist of a rotor, vanes, and a cavity. The rotor is positioned eccentrically within the cavity, and the vanes are free to slide in and out of the rotor slots. As the rotor turns, the vanes move outward due to centrifugal force and create a series of sealed chambers. The fluid enters these chambers through an inlet port and is then compressed and expelled through an outlet port as the rotor continues to turn.
