2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and capabilities:
For that series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically within the pump casing. Once the vanes rotate, the liquid within the casing forms a liquid ring that is certainly concentric together with the pump casing beneath the centrifugal impact, the cubage between liquid and vanes have a periodic alter, so the function of pumping be carried out. Liquid ring vacuum pumps are from the characteristics of minimal vitality consumption and lower noise. They can be utilised to pump water vapor, inflammable and explosive gas likewise as ordinary gases. With exclusive materials employed for key parts, they will also pump corrosive fuel. Appropriate actuating medium or at times pumped medium is usually picked as actuating liquids, so the pumps can practically take care of all widely utilized for light, chemical, food, electrical electrical power and pharmaceutical industries, and so forth.
