For many years now Roots vacuum pumps have already 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 high pumping speed at the lower inlet pressure with high ultimate vacuum. Since the pump working parts haven’t any contact, such as for example rotors and the end cover, therefore the pump efficiency is certainly 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, pharmaceutical and 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. Therefore, roots vacuum pump is more suitable for pumping large levels of drinking water vapor and solvent with water ring vacuum pump.
