Liquid Ring Vacuum Pumps
Ambient air at atmospheric pressure is drawn in through motive air inlet (A) and passed through a converging diverging nozzle (B). The high velocity air leaving the nozzle entrains the gases or vapors to be handled at the suction inlet (C ) and compresses this load through the Venturi (D) to the inlet pressure of the liquid ring vacuum pump. The pump then compresses the motive air and process gas to atmospheric pressure .
