Roots air Ejector Drinking water Ring pump system gives the Air Ejector in front of Water Band Pump of Roots 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；
Great vacuum，high displacement in smaller inlet gas pressure
Motor isn’t reqired for Surroundings Ejector，so that zero power consumption；Energy saving
With Air Ejector，the gas Air Vacuum Pump china pressure difference between input and output has been decreased，which will decrease the comoressing heat and make the operating 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 meals and medicine industry etc.
Roots Pump with Air 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 procedures. By integrating condition monitoring, information regarding the condition of the vacuum system is always available. Furthermore, condition monitoring increases program availability, allowing users to plan maintenance and repair actions in a useful and anticipatory way and prevents cost-intensive creation downtimes. These advantages result in an extended service life and optimum operational safety. ever-power vacuum pumps can either become aligned vertically or horizontally. This enables maximum pumping swiftness and a far more customized and effective utilization 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 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 needed every four years. An innovative sealing concept in the suction chamber makes the use of sealing gas superfluous in most applications, which also has a positive influence on the working costs. Since the procedure of the Ever-power Roots pumps can be done even at ambient temperatures as high as over 40°C with flexible atmosphere cooling, cost-intensive drinking water cooling is unnecessary.
