Summary:
The 2SK vacuum pump is designed for pumping air and other gases that are slightly corrosive, insoluble in water, and contain minimal solids. It operates by using water that rotates at high speed to create pressure and a closed water cavity, effectively removing air from the suction end of the container.
This double-stage pump offers a higher vacuum level, faster pumping speed, compact design, reliable operation, and easy maintenance and operation.
China-made vacuum pumps are widely used in industries such as food processing, textiles, medicine, and chemical manufacturing, as well as in processes like dipping, drying, and others.
