Roots air Ejector Drinking water Ring pump system offers the Air Ejector in front of Water Band Pump of Roots Water Ring pump system.Comparing to Roots Water Ring Pump system which has the same numbers of Roots pumps，there are the following features；
Great vacuum，high displacement in lower inlet gas pressure
Motor is not reqired for Air Ejector，so that zero power consumption；Energy Air Vacuum Pump china 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 substance and medicine sector；vacuum drying and vacuum impregnation in electrical and light textile sector；frozen-dryer in meals and medicine sector 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 condition of the vacuum program is always available. Furthermore, condition monitoring increases system availability, allowing users to strategy maintenance and repair measures in a useful and anticipatory method and prevents cost-intensive creation downtimes. These advantages result in an extended service life and maximum operational security. ever-power vacuum pumps can either become aligned vertically or horizontally. This enables maximum pumping quickness and a far more customized and efficient utilization 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 travel with energy efficiency course IE4 and the unique rotor geometries of the pumps. The pumps are hermetically sealed to the atmosphere and also have a maximum integral leakage rate of 1·10-6 Pa m3/s. Dynamic seals are removed and, because of this, maintenance is only required every four years. An innovative sealing idea in the suction chamber makes the usage of sealing gas superfluous in most applications, which also offers a positive influence on the working costs. Since the procedure of the Ever-power Roots pumps is possible even at ambient temps as high as over 40°C with flexible atmosphere cooling, cost-intensive drinking water cooling is unnecessary.
