For many years today Roots vacuum pumps have been well 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 lower inlet pressure with high ultimate vacuum. Since the pump running parts haven’t any contact, such as for example rotors and the end cover, so the pump overall performance can be 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 Roots Vacuum Pump china substance pharmaceutical, electric vacuum device manufacturing industries.

In view of the chemical substance, pharmaceutical and other industries require large vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber provides improved, which significantly reducing the bearing cavity and equipment cavity oil emulsification. Therefore, roots vacuum pump is definitely more ideal for pumping large quantities of drinking water vapor and solvent with water ring vacuum pump.
