2.LIQUID (WATER) RING VACUUM PUMPS
Working principle and functions:
For the 
series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically in the pump casing. Once the vanes rotate, the liquid within the casing forms a liquid ring that may be concentric with the pump casing under the centrifugal result, the cubage concerning liquid and vanes possess a periodic modify, so the function of pumping be performed. Liquid ring vacuum pumps are with the options of minimal vitality consumption and lower noise. They will be utilized to pump water vapor, inflammable and explosive gas likewise as ordinary gases. With distinctive supplies used for key elements, they’re able to also pump corrosive gasoline. Appropriate actuating medium or from time to time pumped medium is often chosen as actuating liquids, so the pumps can virtually manage all broadly made use of for light, chemical, foods, electric energy and pharmaceutical industries, etc.
