Liquid ring vacuum pumps remove gasses by means of an impeller rotating freely in an eccentric casing. The pumping is done by a liquid that is fed into the pump and thrown by centrifugal force into a moving ring along the internal casing wall. The Liquid ring vacuum pumps are capable of handling high volumes of vapors, condensables and liquids, without detrimental consequences to the performance of the pump. The pump service liquid can be water or other liquids such as oils, solvents, etc. to satisfy almost any process requirements. Liquid ring vacuum pumps are made of various materials. You can choose from cast iron casing with bronze or stainless steel impellers or an all 316 stainless steel construction, for your liquid ring vacuum pumps.
