PURPOSE: A portable diaphragm pump line is provided to reduce the size of a pump while preventing the leakage of gas, to increase the explosion performance and to control the discharge pressure. CONSTITUTION: A portable diaphragm pump line comprises a first pumping part which comprises a first diaphragm(260) to inhale gas through a first inlet(112) and to discharge to an outlet(122); a second pumping part which comprises a second diaphragm(460) to inhale gas through a second inlet(132) and discharge gas to the outlet; a driving part(300,350) which linearly transfers a first and second diaphragm to make the second pumping part discharge or inhales gas when the first pumping part inhales or discharges the gas; and a housing which accommodates the driving part. |
