Summary:
The 2SK/SK vacuum pump is designed to handle air and other non-corrosive gases that are insoluble in water and contain minimal solid particles. It is particularly effective in applications where a liquid ring is used for sealing and cooling.
This pump uses water as a working fluid, which rotates at high speed to create pressure and form a closed water cavity. This mechanism helps to remove air from the suction side of the container efficiently.
Pumps with a double-stage design offer higher vacuum levels, faster pumping speeds, compact structures, reliable performance, and ease of operation and maintenance.
These vacuum pumps are widely used in industries such as food processing, textiles, pharmaceuticals, chemicals, and various manufacturing processes involving dipping, drying, or other similar techniques.
