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.
