2SK series two-stage water ring vacuum pump is equivalent to two SK series water ring vacuum pumps used in series.
Since SK series water ring vacuum pump can only reach the limit vacuum degree of - 700mmHg, in order to reach a higher vacuum and have a larger pumping rate under high vacuum, 2SK series vacuum pump was developed in China in the 1980s.
With the emergence of a new generation of energy-saving products of 2BV and 2BE1 series, 2SK series will be gradually replaced in many occasions.
Although the 2SK-P1 series two-stage water ring vacuum pump atmospheric jet pump unit mainly works under the absolute pressure of 10-50mmHg, its efficiency in the high vacuum area is low. If long-term operation is required, Roots+water ring vacuum unit can be selected, so as to obtain the best efficiency of air extraction in the high vacuum area.
Our Advantages
Main features:
1,Compared with SK series single-stage water ring vacuum pump, it has the characteristics of high vacuum degree 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,As the structure is of double impeller structure, the manufacturing and maintenance are relatively complicated, and there are many vulnerable parts
