2SK series double-stage water ring vacuum pump is used to pump air or other non-corrosive, water-insoluble gases that do not contain solid particles, so as to obtain a high vacuum in a closed container. It is widely used in vacuum evaporation, vacuum concentration, vacuum reflux, vacuum impregnation, vacuum drying and vacuum smelting in foodstuff, textile, chemical, pharmaceutical, metallurgical and other industries. It is characterized by high vacuum degree, fast pumping speed in high vacuum area, compact structure, easy maintenance, etc. 2SK series is used for working condition with suction pressure lower than -0.08mpa, 2SK-P1 series is used for working condition with suction pressure lower than -0.096mpa.
