              Series ZJ Roots Vacuum Pumps
                 
              The series ZJ Roots vacuum pump is without overflow valve. The figure-of-eight rotors are counter-rotating at a constant speed inside the pump housing for suction and exhaust of gas. Two rotors are supported by two bearings and synchronized by a pair of gears, which ensure these two root ors in certain relative positions. They are near to one another and to the housing without actual contacting, so lubrication is unnecessary in the working housing. The carefully balance operating parts and high precision bevel wheels ensure the pump be operated stably and continuously under the condition of high-pressure difference. Dynamic seal parts use our patent technology and imported oil seals. The vibration of shaft at the shaft seals is controlled to less than 0.02mm against oil leaking. The series ZJ Roots vacuum pump is machined by CNC manufacturing center. "O" rings are used for sealing the pump body, two side covers and two end covers. All parts of pump have good compatibility, so the overhaul is very easy. One-inlet and three-outlet structural design of pump is convenient for users to install and use. The pump can't be operated in dividually and should be used in connection with backing vacuum pump. The screw pump, oil seal pump and water ring pump are all suitable as backing pump for Roots pump. The Roots pump can be used to pump a mass of condensable gases when it connected with screw pump or water ring pump.
