For many years today 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. Because the pump working parts have no contact, such as for example rotors and the finish cover, so the pump functionality can be stable and lengthy service time. low maintenance cost
They’re widely used in vacuum smelting, vacuum welding, vacuum Roots Vacuum Pump china casting, vacuum coating, vacuum drying, vacuum dynamic experiment and chemical substance pharmaceutical, electric vacuum device manufacturing industries.
In view of the chemical substance, pharmaceutical and other industries require large vapor degassing capablity. the sealing structure of roots vacuum pump chamber and the bearing chamber offers improved, which greatly reducing the bearing cavity and equipment cavity oil emulsification. Hence, roots vacuum pump can be more suitable for pumping large levels of water vapor and solvent with drinking water ring vacuum pump.
