For many years now Roots vacuum pumps have already been well established in the region of vacuum technology. In mixture with backing pumps, which compress against the atmosphere, these pumps offer lots of advantages.
Features:
The main benefit of roots vacuum pump is a higher pumping speed at the low inlet pressure with high ultimate vacuum. Since the pump running parts haven't any contact, such as rotors and the finish cover, therefore the pump overall performance is stable and lengthy service time. low maintenance cost
Applications:
They're widely used in vacuum smelting, vacuum welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamic experiment and chemical 
pharmaceutical, electric vacuum device manufacturing industries.
In view of the chemical, pharmaceutical and other industries require large vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber has improved, which significantly reducing the bearing cavity and equipment cavity oil emulsification. Thus, roots vacuum pump can be more suitable for pumping large levels of drinking water vapor and solvent with water ring vacuum pump.
