2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and options:
For the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically in the pump casing. When the vanes rotate, the liquid in the casing kinds a liquid ring that is definitely concentric together with the pump casing under the centrifugal impact, the cubage amongst liquid and vanes possess a periodic change, so the function of pumping be carried out. Liquid ring vacuum pumps are in the capabilities of minimal energy consumption and very low noise. They might be employed to pump water vapor, inflammable and explosive fuel likewise as ordinary gases. With unique supplies made use of for major components, they could also pump corrosive gas. Suitable actuating medium or often pumped medium can be selected as actuating liquids, so the pumps can almost manage all broadly employed for light, chemical, foods, electric electrical power and pharmaceutical industries, etc.
