Audited Supplier SK series liquid ring vacuum pumps and compressors are used to pump or compress air and other non-corrosive, water-insoluble and solid particle-free gases to generate vacuum or pressure in closed containers, and a small amount of liquid is allowed with the inhaled gas. It is widely used in machinery, petrochemical, pharmaceutical, food, sugar industry and paper making. Because the compression process of gas is isothermal, it is unlikely to be dangerous with explosive gases, which makes its application more widely.
2SK series two stage liquid ring vacuum pumps whose suction speed is great even in higher vacuum,are more fit to work when the suction pressure is between -0.085MPa~0.095MPa.
