For many years at this point Roots vacuum pumps have already 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.
The main benefit of roots vacuum pump is a higher pumping speed at the lower inlet pressure with high ultimate vacuum. Since the pump running parts Roots Vacuum Pump china haven’t any contact, such as rotors and the end cover, so the pump efficiency is definitely stable and long 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 pharmaceutical, electric vacuum gadget manufacturing industries.
In view of the chemical, pharmaceutical and various other industries require huge vapor degassing capablity. the sealing structure of roots vacuum pump chamber and the bearing chamber provides improved, which significantly reducing the bearing cavity and gear cavity oil emulsification. Therefore, roots vacuum pump is usually more suitable for pumping large levels of water vapor and solvent with water ring vacuum pump.
