Roots vacuum pump is a mechanical vacuum pump with a pair of synchronous high-speed rotation sole-shaped rotor, this pump can not be pumped separately, the front stage needs to be equipped with oil seal, water ring, etc., can be directly discharged into the atmosphere. Its structure and working principle are similar to Roots blower, and its suction port is connected with the vacuum container or the main pump of the vacuum system when it works.

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. Vacuum packing, metallurgy, deaeration, rolling in vacuum metallurgy, and vacuum distillation, vacuum concentration, vacuum drying in chemicals/food/pharmaceutical/wastewater treatment industry, pneumatic conveying system, paper folding system, etc.
