2SK series two-stage water-ring vacuum pump and 2SK-P1 series two-stage water-ring vacuum pump-air jet pump units are used to extract air and other non-corrosive, water-insoluble and solid-free gases in order to obtain higher vacuum in closed vessels.
It has the characteristics of high vacuum, high pumping speed in high vacuum area, compact structure, reliable operation and convenient maintenance. 2SK series is suitable for working conditions with inhalation pressure below - 0.08MPa. 2SK-P1 series is suitable for working conditions where the suction pressure is below -0.096 MPa. When the atmospheric pump is used, the limit vacuum can reach -750 mmHg. The working vacuum range is -0.03-0.08MPa.
