Roots pump with air ejector and water ring pump vacuum system

Roots Pump with Air Ejector and Water Ring Pump Vacuum System

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,there are the following features;
High vacuum,high displacement in lower inlet gas pressure
Motor is not 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 decrease the comoressing heat and make the running more reliable for Roots pump.
APPLICATIONS:
Suitble for high vacuum distillng,vacuum vaporizing and vacuum dehydrating-crystalllzation in chemical and medicine industry;vacuum drying and vacuum impregnation in electric and light textile industry;frozen-dryer in food and medicine industry etc.
