2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and functions:
To the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically from the pump casing. Once the vanes rotate, the liquid from the casing forms a liquid ring which is concentric using the pump casing under the centrifugal result, the cubage involving liquid and vanes have a periodic adjust, so the perform of pumping be performed. Liquid ring vacuum pumps are from the characteristics of very low power consumption and reduced noise. They might be utilized to pump water vapor, inflammable and explosive gas likewise as ordinary gases. With particular elements utilised for key parts, they could also pump corrosive fuel. Ideal actuating medium or sometimes pumped medium can be selected as actuating liquids, so the pumps can pretty much deal with all widely used for 
light, chemical, meals, electrical electrical power and pharmaceutical industries, and so on.
