For many years now Roots vacuum pumps have been well established in the region 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 higher pumping speed at the lower inlet pressure with high ultimate vacuum. Because the pump operating parts haven’t any contact, such as rotors and the end cover, so the pump performance is stable and long service time. low maintenance cost
They’re trusted in vacuum smelting, vacuum welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamic experiment and chemical pharmaceutical, electric vacuum gadget manufacturing industries.
Because of the chemical substance, pharmaceutical and various other industries require huge vapor degassing capablity. the sealing structure of roots vacuum pump chamber and the bearing chamber provides improved, which significantly reducing the bearing cavity and equipment cavity oil emulsification. Therefore, roots vacuum pump is more ideal for pumping large levels of drinking water vapor and solvent with drinking water ring vacuum pump.
