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.
