Roots air Ejector Air Vacuum Pump china Drinking water Ring pump system adds the Air Ejector in front of Water Band Pump of Roots Drinking water Ring pump system.Comparing to Roots Drinking water Ring Pump system that contains the same amounts of Roots pumps，there are the following features；
Large vacuum，high displacement in more affordable inlet gas pressure
Motor is not reqired 
for Atmosphere 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 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 sector 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 procedures. By integrating condition monitoring, information regarding the health of the vacuum system is always available. Furthermore, condition monitoring increases program availability, allowing users to plan maintenance and repair procedures in a good and anticipatory way and prevents cost-intensive production downtimes. These advantages lead to an extended service life and optimum operational protection. ever-power vacuum pumps can either end up being aligned vertically or horizontally. This enables maximum pumping rate 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 in comparison to conventional Roots pumps. This is due to a get with energy efficiency class IE4 and the unique rotor geometries of the pumps. The pumps are hermetically sealed to the atmosphere and also have a maximum essential leakage price of 1·10-6 Pa m3/s. Dynamic seals are eliminated and, consequently, maintenance is only needed every four years. An innovative 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 operating costs. Since the procedure of the Ever-power Roots pumps can be done even at ambient temperature ranges as high as over 40°C with flexible surroundings cooling, cost-intensive water cooling is unnecessary.
