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 plenty of advantages.
The main advantage of roots vacuum pump is a higher pumping speed at the low inlet pressure with high ultimate vacuum. Since the pump operating parts haven’t any contact, such as rotors and the end cover, therefore the pump overall performance is certainly stable and long service time. zero-maintenance cost
They’re trusted 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 various other industries require huge vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber has improved, which greatly reducing the bearing cavity and gear cavity oil emulsification. Therefore, roots vacuum pump can be more ideal for pumping large quantities of water vapor and solvent with water ring vacuum pump.
