China Zjp Series Roots Vacuum Pump Roots Vacuum Pump Set Unit Zjp-300

ZJ Series Roots Vacuum Pump is a positive displacement pump, also known as mechanical booster pump, which is one of the main equipment to obtain the middle and high vacuum degree.
Its working principle is similar to roots blower, which use two figure 8 rotor synchronous rotation in the pump shell, so as to complete the suction and exhaust process.
Features:
The main advantage of ZJ series roots vacuum pump is a high pumping speed at the lower inlet pressure with high ultimate vacuum. Since the pump running parts have no contact, such as rotors and the end cover, so the pump performance is stable and long service time. low maintenance cost
Applications:
They`re widely used in vacuum smelting, vacuum welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamic experiment and chemical pharmaceutical,
electric vacuum device manufacturing industries.
In view of the chemical, pharmaceutical and other industries require huge vapor degassing capablity. the sealing structure of ZJ roots vacuum pump chamber and the bearing chamber has improved, which greatly reducing the bearing cavity and gear cavity oil emulsification.
Thus, ZJ roots vacuum pump is more suitable for pumping large quantities of water vapor and solvent with water ring vacuum pump.
