Variable pitch screw dry vacuum pump

·Cleaning: The pump chamber is completely free of oil and other working media, providing a highly clean vacuum. The vacuum pump will not cause any pollution to the vacuum system;

·Environmental protection: There is no oil or other working medium in the pump chamber, and no waste oil or liquid will be generated. There is no additional exhaust gas emission. Economy, environmental protection, and resource conservation;

·Efficient: Quickly evacuate and achieve maximum vacuum in a short period of time;

·Energy saving: Due to the use of variable pitch irregular screw structure, the power consumption of this series of vacuum pumps is significantly reduced compared to equal pitch screw vacuum pumps;

·Excellent ultimate vacuum degree: The ultimate vacuum can reach 1 Pa;

·Low exhaust temperature: effectively avoids the coking of the extracted gas in the pump caused by high exhaust temperature, which affects the operation of the equal pitch screw vacuum pump;

·Low vibration: The moving parts have undergone precision dynamic balance testing, and the pump runs very smoothly;

·Low noise: Due to the use of variable pitch irregular screws, the working noise of this series of vacuum pumps is significantly reduced compared to equidistant screw vacuum pumps, and the operation is quiet;

·Reliable work, simple use, and easy maintenance: the moving parts inside the pump chamber do not come into contact with each other, with no wear and tear, low wear and tear parts, and low consumables;

The LGB series variable pitch screw vacuum pump can be widely used in vacuum operations in industries such as chemical, pharmaceutical, food, photovoltaic, metallurgical, electronic, and electrical.
