2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and capabilities:
For the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically while in the pump casing. When the vanes rotate, the liquid inside the casing kinds a liquid ring that may be concentric with the pump casing beneath the centrifugal impact, the cubage amongst liquid and vanes have a periodic transform, so the perform of pumping be carried out. Liquid ring vacuum pumps are from the characteristics of lower vitality consumption and lower noise. They are able to be employed to pump water vapor, inflammable and explosive gasoline also as ordinary gases. With particular products used for significant elements, they can also pump corrosive gas. Suitable actuating medium or at times pumped medium could be chosen as actuating liquids, so the pumps can just about handle all broadly utilised for light, chemical, food, electric electrical power and pharmaceutical industries, etc.
