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 plenty of advantages.


The main benefit of roots vacuum pump is a high pumping speed at the lower inlet pressure with high ultimate vacuum. Because the pump running parts have no contact, such as for example rotors and the end cover, therefore the pump overall performance can be stable and lengthy 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 gadget manufacturing industries.

Because 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 has improved, which greatly Roots Vacuum Pump china reducing the bearing cavity and equipment cavity oil emulsification. Hence, roots vacuum pump is more suitable for pumping large quantities of drinking water vapor and solvent with water ring vacuum pump.
