By certification 
2SK series two stage liquid ring vacuum pump is suitable for suction pressure is 160mbar~33mbar working conditions, When suction port with an air injection pump i.e. 2SK-P1 is suitable 40mbar~10mbar working conditions. The pump is widely used food, chemical, pharmaceutical, metallurgy, electronics industry vacuum evaporation, vacuum concentration, vacuum resurgence, vacuum drying and vacuum smelting and so on.
Anti-corrosive treatment of the shaft, reliable anti-return seal, Optimized impeller design,well exhaust structure to ensure novel exhaust structure, ensure the pump of reliable operation, high efficiency and save-energy.
They are widely used for vacuum concentrating, vacuum resurgence, vacuum macerating, vacuum drying and vacuum smelting in electric field, and food, textile, chemical pharmaceutical and metallurgical industries.
Their features are high vacuum, high pumping speed in the high vacuum area, compact structure, reliable operation and convenient maintenance.
