We are offering gas-cooling roots vacuum pump. pumping speed(ls) extreme pressure(pa) maximum allowable pressure(pa) intake and exhaust diameter(mm) caliber anti-air(mm) compression ratio of zero flow equipped with a power range(kw) recommended speed(rmin) single pump with the former pump zjq300 300 1.6x104 different ratio of available105pa10-2pa 8.4x104 160 80 30 430 1500 zjq600 600 200 100 35 7.555 1500.

We are offering pumps dry screw vacuum system with roots pump as mechanical type vacuum pump equipped with a pair of screws in pump housing.lg series screw vacuum pump can realize the gas intake and exhaust by the synchronous rotation of the two screws in high speed.the teo dynamic balanced screws are supported by bearings and installed within pump chamber.there are clearances between the two screws and the pump housing.so the pump operation can be smooth and with a low noise and free of lubricant in the pump chamber.the dry screw pump can be used to pump the gases that contain a mass of vapor and a small quantity of particles.generally the pump has the advantages in energy conservation and easy maintenances, and it is the updated vacuum pump replacing an seal vacuum pump.

We are offering vacuum pumpthe 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.

We offer screw vacuum pumps. Lg series screw vacuum pumps, is my company developed technologically advanced dry vacuum pump (national patent). It works, is the use of two parallel screw pitch, etc., to produce effects for the high-speed suction and discharge synchronized reverse rotation pump chamber. Two screws through fine balancing treatment, supported by bearings mounted in the pump housing, there is a certain gap between the screw and the screw, so when the pump is running smoothly, no friction between them, the working chamber without working medium. Thus, the screw pump could be pumping gas contains large amounts of condensable gases and dust, is environment-friendly, energy-efficient pump. It is a mechanical seal pumps, liquid ring vacuum pumps, reciprocating pumps updates exchange products.

we are offering Roots Vacuum Pumps etc.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.

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.
