  • ZJ Roots Vacuum Pump
    Roots vacuum pump (referred to as roots pump for short) is a non-internal compression type rotary positive displacement pump, which achieves suction and exhaust by two 8-shape rotors rotating in the pump shell. Its principle is similar with roots blower. As it works within the low pressure range, the free paths of the gas molecules are long, and the resistance is strong for gas to pass through small gaps, thus, it is able to obtain a higher compression ratio, and can be used as a booster vacuum pump; but it can not directly exhaust the gas into the atmosphere alone, and it shall be connected with a fore vacuum pump in series, and exhaust the pumped gas into the atmosphere through the fore vacuum pump.
