two.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and characteristics:
To the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically while in the pump casing. Once the vanes rotate, the liquid in the casing types a liquid ring that is certainly concentric with all the pump casing beneath the centrifugal effect, the cubage between liquid and vanes possess a periodic adjust, so the function of pumping be performed. Liquid ring vacuum pumps are of your features of very low power consumption and reduced noise. They are able to be utilized to pump water vapor, inflammable and explosive gasoline as well as ordinary gases. With unique components applied for significant parts, they could also pump corrosive gas. Appropriate actuating medium 
or occasionally pumped medium is often chosen as actuating liquids, so the pumps can just about take care of all extensively utilized for light, chemical, meals, electric power and pharmaceutical industries, and so on.
