For many years at this point Roots vacuum pumps have been well established in the area of vacuum technology. In combination with backing pumps, which compress against the atmosphere, these pumps offer lots of advantages.
The main benefit of roots vacuum pump is a higher pumping speed at the low inlet pressure with high ultimate vacuum. Since the pump working parts haven’t any contact, such as rotors and the end cover, so the pump performance is definitely stable and lengthy service time. zero-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 substance, pharmaceutical and other Roots Vacuum Pump china 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. Hence, roots vacuum pump is more ideal for pumping large levels of water vapor and solvent with drinking water ring vacuum pump.
