Description of  vacuum pmp:　

Water Ring Vacuum Pump--- Liquid Ring Vacuum Pump can be used to pump water vapour as well as ordinary gases. Because they own the features of constant temperature compressing, they can pump inflammable, explosive and corrosive gas. Series 2YK liquid ring vacuum pumps own the features of high vacuum and better applicability. When 2.suitable actuating medium or sometimes pumped medium can be chosen as actuating liquids, the series pumps almost can pump all industrial gases. Aforesaid pumps own the features of reposefully operation, low noise and less 3.than 30 percent of energy consumption compared with water vapour jet vacuum pump. So the liquid ring pumps can be widely used for chemical, light, food, medicine, paper making and electric utility industries etc.
