Roots air Ejector Drinking water Ring pump system adds the Air Ejector in front of Water Band Pump of Roots Drinking water Ring pump system.Comparing to Roots Drinking water Ring Pump system which has the same numbers of Roots pumps，there will be the following features；
Large vacuum，high displacement in lesser inlet gas pressure
Motor is not reqired for Air flow Ejector，so that no power consumption；Energy saving
With Air Ejector，the gas pressure difference between input and output has been reduced，which will decrease the comoressing heat and help to make the working more reliable for Roots pump.
APPLICATIONS：
Suitble for high vacuum Air Vacuum Pump china distillng，vacuum vaporizing and vacuum dehydrating-crystalllzation in chemical and medicine industry；vacuum drying and vacuum impregnation in electrical and light textile market；frozen-dryer in food and medicine industry etc.
Roots Pump with Surroundings Ejector and Water Band Pump Vacuum System
Control and communication will be the essential elements for increasing program availability. The intelligent user interface technology of the Ever-power allows very great adaptation and monitoring of the procedures. By integrating condition monitoring, information about the health of the vacuum system is always available. In addition, condition monitoring increases program availability, enabling users to plan maintenance and repair methods in a good and anticipatory method and prevents cost-intensive production downtimes. These advantages result in an extended service life and optimum operational protection. ever-power vacuum pumps can either be aligned vertically or horizontally. This allows maximum pumping acceleration and a 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 course IE4 and the particular rotor geometries of the pumps. The pumps are hermetically sealed to the atmosphere and also have a maximum integral leakage price of 1·10-6 Pa m3/s. Dynamic seals are eliminated and, as a result, maintenance is 
only needed every four years. A forward thinking sealing concept 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 can be done even at ambient temps of up to over 40°C with flexible air flow cooling, cost-intensive drinking water cooling is unnecessary.
