Summary:
The 2SK/SK vacuum pump is designed for suction of sewage, milking liquids, and other gases that are slightly corrosive, insoluble in water, and contain minimal solid particles.
The pump uses water to create a rotating ring, which generates pressure and forms a sealed cavity to remove air from the suction side of the container.
This double-stage vacuum pump offers higher vacuum levels, greater pumping speed, compact design, reliable operation, and ease of use and maintenance.
It is widely used in industries such as food processing, textiles, medicine, and chemical manufacturing, as well as in processes like dipping and drying.
