  • Series Zj Roots Vacuum Pumps - China

    price: contact company for price

    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.
