Roots pump have ZJ series and ZJP series. As the input pressure is between 6.5-65 Pa, the ZJ series pumping capacity can be reached to 10000L/S. It is a kind of roots vacuum pump in which a couple of lobed rotors turn like 8-shape in high speed synchronously. 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.Customized Roots Vacuum Pump
