  • Series Zjp Roots Vacuum Pumps - China

    price: contact company for price

    The series ZJP roots vacuum pump is with 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 gear, which ensure these two

    rotors in certain relative positions. They are near to one anther 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 part 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. A gravity valve is installed between the suction

    and exhaust part of the pump. The function of the gravity valve is as

    follows, when the pressure difference between the suction and exhaust

    part is over the weight of the valve, the valve opens

    automatically, which makes the pressure difference always keep in a

    fixed controllable valve, This valve is the allowable highest pressure

    difference to ensure the pump work normally and so that in fact, the

    roots vacuum pump with overflow valve is a kind of overload self-

    protective pump. Series ZJP roots vacuum pump with overflow valve has

    substantially higher speed at relatively lower inlet pressure and it is

    possessed overload self-prtotecive function . The Pump is machined by

    CNC manufacturing center. 'O' rings are used for sealing the pump body,

    two sidecovers and two end covers. All parts of pump have good

    compatibility, so the overhaulis very easy. 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 beused to

    pump a mass of condensable gases when it connected with a screw pumkp

    or water ring pump.
