Operating principle and features:
To the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically from the pump casing. When the vanes rotate, the liquid inside the casing varieties a liquid ring that may be concentric together with the pump casing under the centrifugal effect, the cubage in between liquid and vanes have a periodic alter, so the function of pumping be performed. Liquid ring vacuum pumps are in the capabilities of low energy consumption and minimal noise. They are able to be employed to pump water vapor, inflammable and explosive gas at the same time as ordinary gases. With unique elements applied for main parts, they could also pump corrosive gasoline. Suitable actuating medium or often pumped medium is often selected as actuating liquids, so the pumps can virtually handle all widely utilised for light, chemical, foods, electric energy and pharmaceutical industries, and so forth.
