Composite liquid ring vacuum pumps

Composite liquid ring vacuum pumps (1-2 Week delivery)


28 CFM

Our composite liquid ring vacuum pump was developed as an alternative to stainless steel pumps and are ideally suited for applications requiring excellent corrosion resistance at a fraction of the cost of stainless steel. All wet components are constructed of a proprietary plastic composite designed with chemical resistance and longevity in mind. Years of rigorous research and field trials have proven our pumps offer supreme performance and value. This pump is well suited for “wet vacuum” applications with “carry over” of liquid and entrained solids may occur.
