two.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and options:
For that 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 from the casing kinds a liquid ring that may be concentric with the pump casing beneath the centrifugal result, the cubage among liquid and vanes have a periodic adjust, so the function of pumping be performed. Liquid ring vacuum pumps are with the functions of lower power consumption and minimal noise. They might be applied to pump water vapor, inflammable and explosive fuel too as ordinary gases. With distinctive products utilized for big parts, they are able to also pump corrosive gas. Appropriate actuating medium or often pumped medium is often chosen as actuating liquids, so the pumps can nearly 
deal with all extensively utilised for light, chemical, food, electric electrical power and pharmaceutical industries, etc.
