For many years today Roots vacuum pumps have already been well established in the region of vacuum technology. In combination 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 lower inlet pressure with high ultimate vacuum. Because the pump working parts have no contact, such as rotors and the end cover, therefore the pump efficiency can be stable and lengthy service time. zero-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.
In view 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 significantly reducing the bearing cavity and gear cavity oil emulsification. Therefore, roots vacuum pump is usually more ideal for pumping large levels of drinking water vapor and solvent with water ring vacuum pump.
