For many years right now Roots vacuum pumps have already 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 Roots Vacuum Pump china ultimate vacuum. Because the pump running parts have no contact, such as rotors and the finish cover, therefore the pump efficiency is 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 substance pharmaceutical, electric vacuum gadget manufacturing industries.

Because of the chemical, pharmaceutical and other industries require large vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber has improved, which significantly reducing the bearing cavity and gear cavity oil emulsification. Hence, roots vacuum pump is more ideal for pumping large quantities of drinking water vapor and solvent with drinking water ring vacuum pump.
