The SK series water ring vacuum pump and compressor are used to suck or compress air and other non corrosive, water-insoluble, and solid particle free gases, in order to create a vacuum and pressure in a closed container. A small amount of liquid is allowed to mix in the sucked gas.
The SK series water ring vacuum pumps and compressors are widely used in the fields of machinery, petrochemicals, pharmaceuticals, food, sugar industry, and electronics. Due to the isothermal compression process of gas during operation, it is less prone to danger when compressing and suctioning explosive gases, making it more widely used.
The working vacuum range is -0.03-0.08MPa.

Main features:

• Compact structure and easy maintenance;
• Widely applicable, it can extract various gases containing water vapor, flammable, explosive, small amounts of dust, and small amounts of liquid;
• Mainly using water as the working medium, with low maintenance costs;
• Can work in harsh environments.

• Technical Parameter
