Roots air Ejector Water Ring pump system offers the Air Ejector in front of Water Ring 
Pump of Roots Water Ring pump program.Comparing to Roots Water Ring Pump system that contains the same amounts of Roots pumps，there are the following features；
Great vacuum，high displacement in more affordable inlet gas pressure
Motor isn’t reqired for Surroundings Ejector，so that zero 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 produce the running 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 electric powered 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 health of the vacuum system is always available. In addition, condition monitoring increases system availability, enabling users to plan maintenance and repair measures in a good and anticipatory way and prevents cost-intensive production downtimes. These advantages result in an extended service life and optimum operational security. ever-power vacuum pumps can either end up being aligned vertically or horizontally. This allows maximum pumping acceleration and a far more customized and effective usage 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 get with energy efficiency course IE4 and the particular rotor geometries of the pumps. The pumps are hermetically Air Vacuum Pump china sealed to the atmosphere and also have a maximum integral leakage price of 1·10-6 Pa m3/s. Dynamic seals are eliminated and, as a result, maintenance is only required every four years. A forward thinking sealing concept in the suction chamber makes the use of sealing gas superfluous generally in most applications, which also has a positive effect on the working 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 air flow cooling, cost-intensive drinking water cooling is unnecessary.
