Roots air Ejector Drinking water Ring pump system gives the Air Ejector before Water Band Pump of Roots Water 
Ring pump program.Comparing to Roots Drinking water Ring Pump system that contains the same amounts of Roots pumps，there are the following features；
High vacuum，high displacement in lower inlet gas pressure
Motor isn’t reqired for Air Ejector，so that zero 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 make the operating more reliable for Roots pump.
APPLICATIONS：
Suitble for high vacuum distillng，vacuum vaporizing and vacuum dehydrating-crystalllzation in chemical and medicine market；vacuum drying and vacuum impregnation in electric and light textile market；frozen-dryer in meals and medicine market etc.
Roots Pump with Atmosphere Ejector and Water Band Pump Vacuum System
Control and communication are the essential factors for increasing system availability. The intelligent user interface technology of the Ever-power allows very great adaptation and monitoring of the processes. By integrating condition monitoring, information regarding the condition of the vacuum system is always available. In addition, condition monitoring increases system availability, permitting users to plan maintenance and repair steps in a useful and anticipatory way and prevents cost-intensive creation downtimes. These advantages result in a long service life and maximum operational security. ever-power vacuum pumps can either become aligned vertically or horizontally. This allows maximum pumping quickness and a far more customized and effective use of space at the customer’s production site.
The maintenance and energy costs of the HiLobe are a lot more than 50% lower compared to conventional Roots pumps. This is due to a drive with energy efficiency course IE4 and the Air Vacuum Pump china particular rotor geometries of the pumps. The pumps are hermetically sealed to the atmosphere and have a maximum essential leakage rate of 1·10-6 Pa m3/s. Dynamic seals are eliminated and, consequently, maintenance is only required every four years. An innovative sealing concept in the suction chamber makes the utilization of sealing gas superfluous in most applications, which also has a positive influence on the working costs. Since the operation of the Ever-power Roots pumps is possible even at ambient temps as high as over 40°C with flexible air cooling, cost-intensive drinking water cooling is unnecessary.
