How Liquid Ring Vacuum Pumps Work

Liquid ring vacuum pumps feature an eccentrically mounted impeller that rotates in a housing partially filled with operating fluid.
The impeller blades dip into the fluid, and the centrifugal force exerted by their rotation forms a so-called liquid ring within the housing.
The pumped medium is transported in the spaces between the blades and the liquid ring.
The eccentric rotation of the impeller alters the volume of these spaces, causing gas to be drawn in, compressed and expelled.
