Summary:
The 2SK/SK vacuum pump is designed for suction of air and other gases that are slightly corrosive, insoluble in water, and contain minimal solids. It utilizes a liquid ring to create pressure and remove air from the container during the suction process.
This double-stage pump offers higher vacuum levels, faster pumping speeds, a compact design, reliable operation, and easy maintenance. It is widely used in various industries such as food, textile, pharmaceuticals, and chemical processes.
