The UVHE rank ejectors are used as attachment to the liquid ring vacuum pumps UVHD. The equipment, consisting of an ejector and liquid ring vacuum pump, is intended to exhaust air, gas, steam at a pressure from below 6 kPa absolute pressure up to 0,5 kPa absolute pressure. Vacuum pumps with ejectors find their application in food, chemical, metallurgical and construction industry. They are intended to exhaust air, gases and vapors, mainly from water vapors. Vacuum pumps in the ZC, TC, AC version may exhaust gases which are chemically aggressive. Gases may be slightly contaminated by solid particles. The dimension of a solid grain can not exceed 0,1 mm.
Vacuum pumps with ejectors can be used in potentially explosive atmosphere. They are certificated to I M2 and II 2G IIC T4 atmosphere.
