For many years right now Roots vacuum pumps have been well established in the region of vacuum technology. In combination with backing pumps, which compress against the atmosphere, these pumps offer lots of advantages.
The main advantage of roots vacuum pump is a higher pumping speed at the lower inlet pressure with high ultimate vacuum. Since the pump running parts haven’t any contact, such as rotors and the finish cover, so the pump overall performance is certainly 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 substance pharmaceutical, electric vacuum device manufacturing industries.
In view of the chemical, pharmaceutical and additional industries require huge vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber offers improved, which significantly 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 drinking water ring vacuum pump.
