2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and characteristics:
For that series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically inside the pump casing. When the vanes rotate, the liquid from the casing types a liquid ring that is certainly concentric using the pump casing beneath the centrifugal impact, the cubage between liquid and vanes possess a periodic adjust, so the function of pumping be carried out. Liquid ring vacuum pumps are on the functions of lower vitality consumption and minimal noise. They could be utilized to pump water vapor, inflammable and explosive gas likewise as ordinary gases. With special supplies applied for significant elements, they are able to 
also pump corrosive gasoline. Ideal actuating medium or often pumped medium might be selected as actuating liquids, so the pumps can just about manage all widely made use of for light, chemical, food, electric power and pharmaceutical industries, etc.
