Roots air Ejector 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 amounts of Roots pumps，there will be the following features；
Large vacuum，high displacement in smaller 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 decreased，which will decrease the comoressing heat and produce the operating more reliable for Roots pump.
APPLICATIONS：
Suitble for high vacuum distillng，vacuum vaporizing and vacuum dehydrating-crystalllzation in chemical substance and medicine sector；vacuum drying and vacuum impregnation in electric powered and light textile industry；frozen-dryer in food and medicine market etc.
Roots Pump with Air Ejector and Water Ring Pump Vacuum System
Control and communication will be the essential elements for increasing program availability. The intelligent interface technology of the Ever-power allows very good adaptation and monitoring of the processes. By integrating condition monitoring, information regarding the health of the vacuum system is always available. In addition, condition monitoring increases system availability, enabling users to program maintenance and repair procedures in a good and anticipatory way and prevents cost-intensive production downtimes. These advantages lead to an extended service life and optimum operational protection. ever-power vacuum pumps can Air Vacuum Pump china either become aligned vertically or horizontally. This enables maximum pumping rate and a more customized and efficient usage of space at the customer’s production site.
The maintenance and energy costs of the HiLobe are a lot 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 have a maximum essential 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 has a positive effect on the operating costs. Since the 
procedure of the Ever-power Roots pumps can be done even at ambient temps as high as over 40°C with flexible atmosphere cooling, cost-intensive water cooling is unnecessary.
