    How Does a Rotary Vane Pump Work?

     

    Oil-Lubricated Rotary Vane Pumps

     

    These pumps operate using a rotor positioned eccentrically within a stator chamber. As the rotor turns, vanes slide outward to maintain consistent contact with the chamber walls. Oil functions as a lubricant, sealing agent, and cooling medium, improving efficiency and reducing wear. This design allows oil lubricated rotary vane pumps to maintain stable vacuum levels and long operating life. In applications requiring deep, consistent vacuum, systems configured as oil sealed rotary vane vacuum pumps provide enhanced internal sealing and efficient vapor handling.

     

    Dry Running Rotary Vane Pumps

     

    Dry running pumps operate with vanes that create vacuum or pressure without oil in the compression chamber, ensuring clean, contamination-free airflow ideal for environmentally sensitive applications.
