2SK series two-stage water ring vacuum pump can work well like two sets of SK series water ring vacuum pump. Due to SK series vacuum pumps only can reach the maximum vacuum is -700mmHg, in order to get the high vacuum and the large pumping speed, China developed the 2SK series water ring vacuum pump in 80s in the 20th century. It is widely used for vacuum evaporation, vacuum drying and others in food, textile, chemical, pharmaceutical, metallurgy, electronic industrial fields.

2SK series water ring vacuum pump and 2SK-P1 air jet pump unit

Main features:

1.  Compared with SK water vacuum pump, it gets higher vacuum and larger pumping speed etc.
2. Simple structure and easy to maintain

3. The mostly working medium is water and low maintenance costs. 
4. The pump is widely used in many areas, it can suction vapor, flammable, explosive gases, and various gases contain a small amount of dust and liquid.

 5. The pump can work in the harsh conditions.
