2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and characteristics:
For that series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically in the pump casing. Once the vanes rotate, the liquid during the casing kinds a liquid ring that may be concentric using the pump casing beneath the centrifugal impact, the cubage in between liquid and vanes have a periodic modify, so the function of pumping be carried out. Liquid ring vacuum pumps are on the capabilities of very low vitality consumption and 
low noise. They're able to be employed to pump water vapor, inflammable and explosive fuel likewise as ordinary gases. With special components used for big elements, they could also pump corrosive fuel. Suitable actuating medium or occasionally pumped medium can be picked as actuating liquids, so the pumps can practically manage all extensively utilised for light, chemical, meals, electric energy and pharmaceutical industries, and so forth.
