2SK Series Water Ring Vacuum Pumps and 2SK-P1 series two-stage water ring vacuum pumps—atmospheric jet pump units are used to extract air and other non-corrosive, water-insoluble, and non-solid particles-free gases in order to obtain a higher vacuum in a closed container . The 2SK series is suitable for working conditions where the suction pressure is lower than -0.08MPa. 2SK-P1 Series Liquid Vacuum Pump is suitable for working conditions where the suction pressure is lower than -0.096MPa. When equipped with an atmospheric pump, the ultimate vacuum can reach -750mmHg. The working vacuum range is -0.03-0.08MPa.
Model meaning of 2SK series water ring vacuum pump unit:
For example: 2SK-3P1
2SK - two-stage water ring vacuum pump
3 - maximum gas
P1 - with one-stage atmospheric ejector
