2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and features:
For that series 
SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically inside the pump casing. Once the vanes rotate, the liquid while in the casing types a liquid ring that may be concentric with the pump casing under the centrifugal result, the cubage between liquid and vanes have a periodic alter, so the perform of pumping be performed. Liquid ring vacuum pumps are on the characteristics of low power consumption and minimal noise. They can be utilised to pump water vapor, inflammable and explosive gas too as ordinary gases. With distinctive components made use of for major parts, they’re able to also pump corrosive gas. Appropriate actuating medium or occasionally pumped medium could be selected as actuating liquids, so the pumps can virtually manage all broadly utilized for light, chemical, meals, electric energy and pharmaceutical industries, etc.
