For many years today Roots vacuum pumps have been well established in the area 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 operating parts haven’t any contact, such as rotors and the end cover, so the pump efficiency is 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 gadget manufacturing industries.
Because of the chemical substance, pharmaceutical and other industries require large vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber provides improved, which greatly reducing the bearing cavity and equipment cavity oil emulsification. Therefore, roots vacuum pump is certainly more ideal for pumping large levels of drinking water vapor and solvent with water ring vacuum pump.
