Roots vacuum pumps have ZJ series and ZJP series, provide 150-10,000L/s pumping speed with 5×10⁻² Pa ultimate pressure, It is a kind of roots vacuum pumps 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. But it can not discharge the gas to atmosphere directly and requires to be used with a fore vacuum pump in series connection.
ZJP Roots Vacuum Pumps is a positive displacement pump, also known as mechanical booster pump, which is one of the main equipment to obtain the middle and high vacuum degree. Its working principle is similar to roots blower, which use two figure 8 rotor synchronous rotation in the pump shell, so as to complete the suction and exhaust process.
