The useful range of a liquid ring vacuum pump may be extended using an Atmospheric Air Ejector on the suction flange It acts as an extra pumping stage As the name implies the motive for this ejector is air at atmospheric pressure While the suction pressure of the liquid ring vacuum pump is in the 50-75 torr range the ejector can pull the process down to the 5-10 torr range Crystaltcs manufactures a comprehensive range of Atmospheric Air Jet Ejectors used to extend the operating range of Liquid Ring Vacuum Pumps In operation an Atmospheric Air Jet Ejector uses the energy available from the expansion of atmospheric air to the Liquid Ring Pump inlet pressure to drive the Ejector Atmospheric air enters the Ejector and passes through the nozzle where the pressure energy is converted into kinetic energy On leaving the nozzle at high velocity a region of low pressure is created in the suction chamber which entrains the process fluid The two streams then combine within the throat of the Ejector before being decelerated in the outlet cone to recover pressure to suit the Liquid Ring Pump inlet capability For More Information Please Contact us or call on 91 253 2501600 http www crystaltcs com atmospheric-air-ejector php
