JZPX series roots-rotary pump system contains ZJ series roots pump as main pump and single or double stage rotary vane pump as fore pump. It is an ideal machine to achieve for low or high vacuum degree. Besides, the whole system will match the connecting pipe, valve, electric cabinet, and water cooling system (except for the two smallest models) as well. All components are assembled in one shell frame with the pumps, which is compact-designed and convenient to operation.


JZPX series system is your wonderful choice to remain high vacuum. It can continuously work for long time and owns the character of low noise. With a magnetic discharge valve (which will start or stop together with the fore pump)connecting the fore pump and pipe, this system can prevent the oil on the rotary pump being sucked back to the vacuum tank.


With the capability of sucking incondensable or non-corrosive air, as well as atmosphere, JZJX series roots-rotary system is widely applied in varied vacuum system for low or high vacuum, or high pumping capacity. Such as vacuum smelting, molten steel degassing, vacuum sintering,a dynamic vacuum achieving in large space simulation test, vacuum impregnation treating for power capacitors or transformers,

exhaust on fluorescent tube or bulb automatic production line, continuous air discharge for vacuum flask manufacturing, pre-pumping for vacuum coating machine, pumping for magnesium reduction process, degassing for single crystal silicon refining process, etc.
