two.LIQUID (WATER) RING VACUUM PUMPS
Working principle and features:
For your series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically from the pump casing. When the vanes rotate, the liquid during the casing forms a liquid ring which is concentric using the pump casing beneath the centrifugal result, the cubage amongst liquid and vanes have a periodic change, so the function of 
pumping be performed. Liquid ring vacuum pumps are with the options of very low vitality consumption and very low noise. They’re able to be employed to pump water vapor, inflammable and explosive gasoline also as ordinary gases. With particular components applied for important elements, they will also pump corrosive gas. Appropriate actuating medium or at times pumped medium can be picked as actuating liquids, so the pumps can just about handle all broadly applied for light, chemical, food, electrical energy and pharmaceutical industries, and so forth.
