Liquid ring vacuum pumps and compressors are rotary machines. They operate according to the positive displacement principle. In these machines, a liquid is In general, large and medium-sized liquid ring gas pumps are of single-acting design. Operating principle and types of design. 7. Liquid ring gas pump. Single- When compressing dry gases or vapours which neither condense in the inlet chamber nor during the compression process, the liquid ring gas pump operates as a Since the impeller is located eccentric to the pumping chamber, the depth of entry of the blades into the liquid ring decreases and increases as the impellerThe operating principle of a liquid ring pump depends on a continuous supply of clean service liquid, which is normally water. The liquid enters the pump 4.1 - PRINCIPLE OF OPERATION (See figure at side). The aspirated gas enters the pump chamber A-B via the pump suction flange. The gas is trapped between 2 Operating principle. As an operating fluid, liquid ring vacuum pumps use water or a liquid compatible with the gas or vapor to be evacuated.
