Roots air Ejector Water Ring pump system gives the Air Ejector before Water Ring Pump of Roots Water Ring pump program.Comparing to Roots Air Vacuum Pump china Drinking water Ring Pump system which has the same numbers of Roots pumps，there will be the following features；
Large vacuum，high displacement in lower inlet gas pressure
Motor isn’t reqired for Atmosphere 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 substance and medicine market；vacuum drying and vacuum impregnation in electrical and light textile industry；frozen-dryer in food and medicine sector etc.
Roots Pump with Atmosphere Ejector and Water Band Pump Vacuum System
Control and communication are the essential elements for increasing program availability. The intelligent user interface technology of the Ever-power allows very great adaptation and monitoring of the processes. By integrating condition monitoring, details about the health of the vacuum system is always available. Furthermore, condition monitoring increases system availability, permitting users to program maintenance and repair measures in a good and anticipatory method and prevents cost-intensive creation downtimes. These advantages lead to a long service life and optimum operational safety. ever-power vacuum pumps can either become aligned vertically or horizontally. This enables maximum pumping rate 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 compared 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 have a maximum integral leakage price of 1·10-6 Pa m3/s. Dynamic seals are eliminated and, consequently, 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 influence on the operating costs. Since the operation of the Ever-power Roots pumps can be done even at ambient temperatures of up to over 40°C with flexible atmosphere cooling, cost-intensive water cooling is unnecessary.
