Type SK water circulation vacuum pump and compressor is used to pump and compress air or other non-corrosive, water-insoluble and no-solid-granule-contained gases to vacuumize and pressurize a space in a closed container. Inhaled gases are allowed to be mixed with small amount of liquids. Type SK pump is widely applied in the industries of mechanical, petroleum, chemical, pharmaceutical, food, ceramic, sugar refining, printing and dyeing, metallurgy and etc.

Because the gases are compressed under the operating condition of constant temperature, the pump can pump and compress corrosive, flammable and explosive gases safely, thus, it can be applied more extensively.
