Roots Vacuum Pump

For many years today Roots vacuum pumps have been well established in the area of vacuum technology. In mixture with backing pumps, which compress against the atmosphere, these pumps offer plenty of Roots Vacuum Pump china advantages.


The main advantage of roots vacuum pump is a higher pumping speed at the low inlet pressure with high ultimate vacuum. Because the pump running parts haven’t any contact, such as for example rotors and the finish cover, therefore the pump performance is usually stable and long 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.

Because of the chemical, pharmaceutical and various 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. Thus, roots vacuum pump is usually more suitable for pumping large quantities of drinking water vapor and solvent with drinking water ring vacuum pump.
