For many years now Roots vacuum pumps have already been well Roots Vacuum Pump china established in the region of vacuum technology. In mixture with backing pumps, which compress against the atmosphere, these pumps offer lots of advantages.
The main benefit of roots vacuum pump is a high pumping speed at the low inlet pressure with high ultimate vacuum. Since the pump running parts have no contact, such as rotors and the finish cover, so the pump performance is stable and long service time. zero-maintenance cost
They’re trusted in vacuum smelting, vacuum welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamic experiment and chemical pharmaceutical, electric vacuum device manufacturing industries.
Because of the chemical, pharmaceutical and additional industries require large vapor degassing capablity. the sealing structure of roots vacuum pump chamber and the bearing chamber has improved, which significantly reducing the bearing cavity and equipment cavity oil emulsification. Hence, roots vacuum pump is certainly more ideal for pumping large levels of drinking water vapor and solvent with water ring vacuum pump.
