For that series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically inside the pump casing. Once the vanes rotate, the liquid in the casing varieties a liquid ring which is concentric with the pump casing under the centrifugal effect, the cubage among liquid and vanes have a periodic alter, so the perform of pumping be carried out. Liquid ring vacuum pumps are from the functions of reduced power consumption and low noise. They might be utilised to pump water vapor, inflammable and explosive gasoline as well as ordinary gases. With unique resources applied for key parts, they can also pump corrosive gas. Suitable actuating medium or occasionally pumped medium is usually chosen as actuating liquids, so the pumps can nearly deal with all widely made use of for light, chemical, food, electric power and pharmaceutical industries, etc.
