DESCRIPTION:Roots air Ejector Water Ring pump system adds the Air Ejector in front of Water Ring Pump of Roots Water Ring pump system. Comparing to Roots Water Ring Pump system that contains the same numbers of Roots pumps.
FEATURES:1. High vacuum, high displacement in lower inlet gas pressure
2. Motor is not required for Air Ejector, so that no power consumption;
3. Energy saving
4. With Air Ejector, the gas pressure difference between input and output has been reduced, which will decrease the compressing heat and make the running more reliable for Roots pump.
APPLICATIONSuitable for high vacuum distilling, vacuum vaporizing and vacuum dehydrating-crystallization in chemical and medicine industry; Vacuum drying and vacuum impregnation in electric and light textile industry; Frozen-dryer in food and medicine industry etc.
PARAMETER:1. Roots Pump with Air Ejector and Water Ring Pump Vacuum System
2. Main specifications for two roots pumps with air ejector and water ring pump vacuum system
