Air Ejector Water Ring Vacuum Pumps

Additional Details

The maximum vacuum which can be created by Watering Vacuum Pump is limited to 93.3% i.e watering vacuum pump create ultimate pressure of 50 mm Hg. This vacuum will be created with full closed suction. In other words, the capacity of the pump will be zero when it is operates at vacuum of 93.3%. In process, due to gas generation, the Vacuum Pump will never create 93.3% vacuum.


To achieve more vacuum and to have suction capacity even at high vacuum, we recommend the installation of Air Ejector. Air Ejector when used in conjunction with Watering Vacuum Pump, creates maximum vacuum in the range of 97-98%. However, the affect of air ejector to increase the vacuum, can be seen in the process where vacuum pump alone creates 92.5% vacuum. In such process, ejector should be used in conjunction with vacuum pump so as to achieve high vacuum in process. Installation of the Air Ejector does not call for any additional power connection. These are no parts subject to where and tear and hence, there is no mechanical maintenance for the Air Ejector. The installation of the Air Ejector is as per the photograph. Initially, medium will be sucked from the system directly and subsequently, i.e. after achieving 92.5% vacuum, medium will be sucked through the Air Ejector.
