Roots air Ejector Water Ring pump system adds the Air Ejector before Water Band Pump of Roots Drinking water Ring pump system.Comparing to Roots Water Ring Pump system that contains the 
same amounts of Roots pumps，there are the following features；
High vacuum，high displacement in lesser inlet gas pressure
Motor isn’t reqired for Air Ejector，so that no power consumption；Energy saving
With Air Ejector，the gas pressure difference between input and output has been reduced，which will reduce the comoressing heat and make the working more reliable for Roots pump.
APPLICATIONS：
Suitble for high vacuum distillng，vacuum vaporizing and vacuum dehydrating-crystalllzation in chemical substance and medicine industry；vacuum drying and vacuum impregnation in electric powered 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 will be the essential factors for increasing program availability. The intelligent interface technology of the Ever-power allows very great adaptation and monitoring of the processes. By integrating condition monitoring, details about the condition of the vacuum system is always available. In addition, condition monitoring increases system availability, permitting users to program maintenance and repair steps in a good and anticipatory method and prevents cost-intensive creation downtimes. These advantages result in a long service life and maximum operational basic safety. ever-power vacuum pumps can either become aligned vertically or horizontally. This enables maximum pumping velocity and a more customized and effective 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. This is due to a get with energy efficiency class IE4 and the particular rotor Air Vacuum Pump china 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, as a result, maintenance is only required every four years. An innovative sealing idea in the suction chamber makes the usage of sealing gas superfluous generally in most applications, which also offers a positive influence on the working costs. Since the operation of the Ever-power Roots pumps is possible even at ambient temperature ranges as high as over 40°C with flexible atmosphere cooling, cost-intensive water cooling is unnecessary.
