Applications for Liquid Ring Vacuum Pumps

A liquid ring vacuum pump consists of a cylindrical housing with an eccentrically placed rotor powered by a motor. As the rotor spins, the centrifugal force of the vanes thrust the seal liquid towards the inner walls of the housing, creating a liquid ring. This ring seals the space in between the vanes which become the chambers by which process material is transferred. The eccentric placement causes a change in volume of the chamber, creating an expansion and compression effect on the process material. The pressure differential that results from the fluctuation of the volume, along with the positive displacement of the rotor, creates vacuum. This vacuum and suction effect is incredibly useful and applicable to a vast range of applications, limited only by imagination.
