  Roots Vacuum Pump( Booster pump) is a positive displacement vacuum equipment.That pump can be acts main pump also backing pump for vacuum system especially used in low inlet pressure application due to it still have high pumping capacity during the low inlet pressure. It is a kind of roots vacuum pump in which a couple of lobed rotors turn like 8-shaped in high speed synchronously rotating opposite directions. Two rotors rotate and produce aspiration and exhaust which principle is just like a roots blower. As it works in a lower pressure, the free flow distance of gas molecule is longer and the resistance of gas passing a small gap is much large. Thus, a bigger compression ratio can be gained so that it can also be used as a blower pump. But it can not discharge the gas to atmosphere directly and requires to be used with a fore vacuum pump in series connection.
