For many years at this point Roots vacuum pumps have already been well established in the region of vacuum technology. In combination 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 low inlet Roots Vacuum Pump china pressure with high ultimate vacuum. Since the pump operating parts have no contact, such as rotors and the end cover, therefore the pump performance is stable and lengthy service time. low 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 device manufacturing industries.

In view of the chemical, pharmaceutical and various other industries require huge vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber offers improved, which greatly reducing the bearing cavity and gear cavity oil emulsification. Hence, roots vacuum pump is usually more suitable for pumping large levels of drinking water vapor and solvent with water ring vacuum pump.
