For many years right now 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 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 have no contact, such as for example rotors and the finish cover, so the pump efficiency is certainly 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.
Because of the chemical substance, pharmaceutical and various other industries require large vapor degassing capablity. the sealing structure 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 definitely more suitable for pumping large quantities of water vapor and solvent with drinking water ring vacuum pump.
