SK series water ring vacuum pumps and compressors

Download the brochure of SK series(pdf)

SK series water ring vacuum pumps and compressors are designed and developed in 1980s in China.　
In technology side, the SK series products have been replaced completely by the 2BV or 2BE1 series vacuum pumps and compressors.
We don't recommend this series products.


Main characteristics：

To adopt the low grade criteria: the outdated technology, the HT impeller, the bearing made in China. The price is lower. The vacuum and the efficiency of the pumps is very low, too.
