Summary:
The 2SK vacuum pump is a liquid ring vacuum pump designed for suctioning sewage and milking liquids. It is primarily used to pump air and other gases that are slightly corrosive, insoluble in water, and contain minimal solids.
The pump operates by using water that rotates at high speed to create pressure and form a closed water cavity, which removes air from the container on the suction side.
Pumps with a double-stage structure offer higher vacuum levels, greater pumping speeds, compact design, reliable operation, and ease of use and maintenance.
These vacuum pumps are widely used in industries such as food processing, textiles, medicine, and chemicals, as well as in processes like dipping and drying.
