two.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and options:
For the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically within the pump casing. When the vanes rotate, the liquid within the casing kinds a liquid ring that is definitely concentric together with the pump casing beneath the centrifugal result, the cubage involving liquid and vanes have a periodic change, so the function of pumping be performed. Liquid ring vacuum pumps are on the capabilities of lower power consumption and low noise. They can be employed to pump water vapor, inflammable and explosive gas as well as ordinary gases. With particular supplies made use of for significant elements, they will also pump corrosive gas. Appropriate actuating medium or 
often pumped medium may be selected as actuating liquids, so the pumps can nearly manage all broadly employed for light, chemical, foods, electric power and pharmaceutical industries, and so on.
