Heavy duty one-stage liquid ring the vacuum pump
Production Description
1. Heavy duty one-stage liquid ring the vacuum pump high vacuum large CFM water circulation vacuum pump is used to suck or compress air and other gas that is non-corrosive, insoluble in water and without solid.
2. The vacuum and pressure can be obtained in the sealed container after air discharged. However, gas with little water is allowed.
3. Pump works with water fed into pump, the water in pump will revolve in high speed to form sealed water cavity to take air away. It is a safe pump with high efficiency.
4. It is widely used in several sectors such as mechanical, petrochemical, pharmaceutical, food, sugar making and electronic industry.
