2-Stage Liquid Vacuum Pumps Series 2SK
2SK series two stage water ring vacuum pump and 2SK-P1 series two stage water ring vacuum pump with air ejector system are used for sucking air or other uncorrosive, unsoluble gases which do not contain solid grains to obtain higher vacuum in sealed vessels.
lt is widely used for vacuum vaporizing, vacuum coneentrating, vacuum resurgence, vacuum maceration, vacuum drying and vacuum smeltion in food, textile, chemical, pharmaceutical, and metallurgy industries.
lt is characterized by higher vacuum, bigger pumping speed in the high vacuum region, compact structure, reliable operation and casy maintenance.

Performance curves
 Note:
1. The data in the table are obtained under the following eondition
(1). Atmosphere 10l.3KPa.
(2). Water tempereture 15οC.
(3). Air tempereture 20οC
(4). Relative humidi \ty 70%
2. the flow of supplying water in the table are measureed when the suction vasuum is 46.7 KPa. When ultimate Pressure under it may be higher then this.
3. The deviation of pumping speed will be 10%.
