Product Description
The roots vacuum pump is a mechanical vacuum pump with a pair of synchronous high-speed rotation sole-shaped rotors, this pump can not be pumped separately, the front stage needs to be equipped with an oil seal, water ring, etc., and can be directly discharged into the atmosphere. Its structure and working principle are similar to Roots blower, and its suction port is connected to the vacuum container or the main pump of the vacuum system when it works.
Fast start, less power consumption, low operation and maintenance costs, large pumping speed, high efficiency, insensitivity to a small amount of water vapor and dust contained in the pumped gas, and a larger pumping rate, can quickly eliminate the sudden release of gas. The machine is widely used in vacuum packaging, vacuum metallurgy refining, degassing, and rolling, as well as chemical, food, and pharmaceutical industries in vacuum distillation, vacuum concentration and vacuum drying.

Our Advantages
Roots vacuum pump is a dry rotary vane vacuum pump, with no oil, no pollution, no vibration and other advantages. It is suitable for applications requiring high pumping speed and high vacuum, such as semiconductor manufacturing, vacuum smelting and other fields. Roots vacuum pump has high pumping speed, good stability, and can quickly reach the required vacuum degree, which is suitable for experiments and processes requiring higher vacuum degree. Because Roots vacuum pumps do not need to use oil lubrication, they have low maintenance costs, long service life and are suitable for long-term stable operation.
1. Higher rotary speed, lower vibration, lower noise level.
2. Noise level can be controlled under 85dba with acoustic enclosure.
3. Special sealing rings ensure the efficient sealing and longer service life.
4. Advanced structure, flow rate changes little when pressure changes.
5. Precise gears keep the blower operating stably.
6. Air cooling type even higher pressure rise.
Application
Roots vacuum pump in petroleum, chemical industry, plastics, pesticides, steam turbine rotor dynamic balance, aerospace space simulation and other devices have been tested for a long time, so it should be vigorously promoted and applied all around the world. It is also widely used in petroleum, chemical, metallurgy, textile and other industries. Vacuum pump accessories as a vacuum pump silencer, used for vacuum pump noise control.
