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 plenty 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 operating parts haven’t any contact, such as rotors and the end cover, so the pump functionality is certainly stable and lengthy service time. zero-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 substance, pharmaceutical and various other industries require huge vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber provides improved, which greatly reducing the bearing cavity and equipment cavity oil emulsification. Therefore, roots vacuum pump is certainly more suitable for pumping large quantities of drinking water vapor and solvent with water ring vacuum pump.
