Roots air Ejector Water Ring pump system gives the Air Ejector before Water Band Pump of Roots Drinking water Ring pump system.Comparing to Roots Water Ring Pump system which has the same amounts of Roots pumps，there are the following features；
Great vacuum，high displacement in more affordable inlet gas pressure
Motor is not reqired for Surroundings Ejector，so that no power consumption；Energy saving
With Air Ejector，the gas pressure difference between input and output has been decreased，which will reduce the comoressing heat and help to make the working more reliable for Roots pump.
APPLICATIONS：
Suitble for high vacuum distillng，vacuum vaporizing and vacuum 
dehydrating-crystalllzation in chemical and medicine industry；vacuum drying and vacuum impregnation in electrical and light textile industry；frozen-dryer in food and medicine industry etc.
Roots Pump with Air Ejector and Water Ring Pump Vacuum System
Control and Air Vacuum Pump china communication will be the essential elements for increasing program availability. The intelligent interface technology of the Ever-power allows very great adaptation and monitoring of the procedures. By integrating condition monitoring, information regarding the condition of the vacuum system is always available. Furthermore, condition monitoring increases system availability, enabling users to strategy maintenance and repair steps in a good and anticipatory method and prevents cost-intensive production downtimes. These advantages result in an extended service life and maximum operational safety. ever-power vacuum pumps can either end up being aligned vertically or horizontally. This allows maximum pumping acceleration and a far more customized and efficient use of space at the customer’s production site.
The maintenance and energy costs of the HiLobe are more than 50% lower in comparison to conventional Roots pumps. That is due to a get with energy efficiency class IE4 and the unique rotor geometries of the pumps. The pumps are hermetically sealed to the atmosphere and also have a maximum essential leakage rate of 1·10-6 Pa m3/s. Dynamic seals are eliminated and, because of this, maintenance is only required every four years. A forward thinking sealing idea in the suction chamber makes the use of sealing gas superfluous generally in most applications, which also offers a positive effect on the working costs. Since the procedure of the Ever-power Roots pumps is possible even at ambient temperatures as high as over 40°C with flexible air cooling, cost-intensive drinking water cooling is unnecessary.
