2SK series two-stage water-ring vacuum pump is equivalent to two SK series water-ring vacuum pumps in series. Because SK series water ring vacuum pump can only reach the limit vacuum of - 700 mmHg, in order to achieve a higher vacuum and higher pumping rate under high vacuum, 2SK series vacuum pump was developed in China in 1980s. With the emergence of 2BV and 2BE1 series of new generation energy-saving products, 2SK series will gradually be replaced in many occasions.

 
Two-stage water-ring vacuum pump-air jet pump unit mainly works at 10-50 mmHg insulation, but its efficiency in high vacuum area is low. Roots water-ring vacuum unit can be selected for long-term operation, so that the best efficiency of high vacuum area can be obtained.
 
It is widely used in vacuum evaporation, vacuum concentration, vacuum moisture regain, vacuum impregnation, vacuum drying and vacuum smelting in food, knitting chemical industry, pharmaceutical and metallurgical industries and electronic fields.
 
Two-stage water ring vacuum pump characteristics:
 
1. Compared with SK series single-stage water ring vacuum pump, it has the characteristics of high vacuum and high pumping speed in high vacuum area.
 
2. At the same pumping rate, the shaft power is higher than 2BV and 2BE1 series.
 
3. Because of the double impeller structure, the manufacture and maintenance are complicated, and there are many vulnerable parts.

Note: 1) The 2SK performance curve is obtained under the standard condition.

2) 2SK series pumps are suitable to deal with high vacuum only, but if it is long term low vacuum or wide working range, the motor should have higher power.
