With the development of the application of vacuum, the vacuum pump has developed a variety of species, their pumping speed from zero point liters per second to hundreds of thousands, millions of liters per second. Depends on the working principle, vacuum pump basically to be divided into two types---gas transfer vacuum pumps and gas binding vacuum pumps. With vacuum technology used widely in production field and scientific research , mostly required several types vacuum pump installed together in a whole vacuum units to meet the research or production demand.

Due to vacuum department required vacuum scope is big, not any one type vacuum pump's performance can be completely meet to all vacuum scope demand for product processing. Adopts different type vacuum pumps according to different working pressure and different working required. Ir order to use easy and meet variety of vacuum processing demand, we combine variety of vacuum pumps into a vacuum units which based in a frame. Screw pump, LRVP, reciprocating pump,rotary piston pump,roots vacuum pump ,diffusion pump etc.are the most important vacuum pumps in our industries.

Recently, With the rapid growth of economy in our country,vacuum pump application continue to expand in any industries which need vacuum that  develop our vacuum pumps fields in steady.
