For many years today 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.
Features:
The main advantage of roots vacuum pump is a higher pumping speed at 
the low inlet pressure with high ultimate vacuum. Since the pump operating parts have no contact, such as for example rotors and the end cover, therefore the pump performance is usually stable and long 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 gadget 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 provides improved, which greatly reducing the bearing cavity and equipment cavity oil emulsification. Hence, roots vacuum pump is certainly more suitable for pumping large quantities of water vapor and solvent with drinking water ring vacuum pump.
