For many years at this point 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 lots of advantages.
The main advantage of roots vacuum pump is a higher pumping speed at the lower inlet pressure with high ultimate vacuum. Because the pump running parts haven’t any contact, such as rotors and the finish 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 device 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 offers improved, which significantly reducing the bearing cavity and equipment cavity oil emulsification. Thus, roots vacuum pump is more ideal for pumping large levels of water vapor and solvent with water ring vacuum pump.
