2.LIQUID (WATER) RING VACUUM PUMPS
Working principle and options:
For your 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 during the casing types a liquid ring that’s concentric with all the pump casing under the centrifugal impact, the cubage involving liquid and vanes possess a periodic transform, so the perform of pumping be performed. Liquid ring vacuum pumps are on the characteristics of very low energy consumption and very low noise. They’re able to be applied to pump water vapor, inflammable and explosive gas too as ordinary gases. With distinctive elements utilised for significant components, they’re able to also pump corrosive gasoline. Appropriate actuating medium or sometimes pumped medium can be chosen as actuating liquids, so the pumps can just about take care of all broadly utilized for light, chemical, meals, electric power and pharmaceutical industries, and so forth.
