2.LIQUID (WATER) RING VACUUM PUMPS
Working principle and options:
For the 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 while in the casing forms a liquid ring that may 
be concentric with all the pump casing beneath the centrifugal effect, the cubage in between liquid and vanes possess a periodic transform, so the perform of pumping be performed. Liquid ring vacuum pumps are of the features of low energy consumption and very low noise. They can be utilized to pump water vapor, inflammable and explosive gasoline as well as ordinary gases. With special supplies used for significant parts, they’re able to also pump corrosive gas. Appropriate actuating medium or often pumped medium may be chosen as actuating liquids, so the pumps can virtually handle all widely utilized for light, chemical, meals, electric power and pharmaceutical industries, and so forth.
