ZJ Roots Vacuum Pump

Products

ZJ series roots vacuum pump is a kind of volumetric pump, also known as mechanical booster pump, which is one of the main equipment for obtaining medium and high vacuum degree. Its working principle is similar to the roots blower, which USES two octon-rotor synchronous rotation to complete the suction and exhaust process in the pump case.

Features
The main advantages of ZJ series roots vacuum pump are low inlet pressure and high vacuum speed. The pump has stable performance and long service life due to the non-rotor and end cover of the pump. Low maintenance cost

Application:
It is widely used in vacuum smelting, vacuum welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamics experiment, chemical pharmaceutical and electric vacuum device manufacturing industry.
In view of chemistry, pharmaceutical and other industries require huge steam degassing capacity. The sealing structure of the cavity and bearing cavity of ZJ roots vacuum pump has been improved, which greatly reduces the emulsification of the bearing cavity and the gear chamber oil. Therefore, the ZJ type roots vacuum pump is more suitable for pumping large amounts of water vapor and solvents with a water ring vacuum pump.
