For many years now Roots vacuum pumps have been well established in the area of vacuum technology. In mixture with backing pumps, which compress against the atmosphere, these pumps offer lots of advantages.
The main advantage of roots vacuum pump is a higher pumping speed at the lower inlet pressure with high ultimate vacuum. Since the pump operating parts have no contact, such as rotors and the end cover, therefore the pump performance can be stable and lengthy service time. low maintenance cost
They’re widely used in vacuum smelting, vacuum welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamic experiment and chemical substance pharmaceutical, electric vacuum device manufacturing industries.
In view of the chemical, pharmaceutical and additional industries require huge vapor degassing capablity. the sealing structure of roots vacuum pump chamber and the bearing chamber has improved, which greatly reducing the bearing cavity and equipment cavity oil emulsification. Hence, roots vacuum pump is certainly more ideal for pumping large levels of water vapor and solvent with drinking water ring vacuum pump.
