Description DC 12V Vacuum Pump Suction Pump with Bracket Negative Pressure Suction Features Micro pump is powered miniature DC motor drive drive internal mechanical eccentric eccentric motion driven by an eccentric movement inside the diaphragm reciprocates Whereby the pump chamber fixed volume of air compression compression suction port is closed the exhaust port is formed to open slightly positive pressure stretching compressed exhaust port is closed a negative pressure sucking mouth open the pumping air intakes with the outside atmospheric pressure difference at a pressure difference the gas pressure suction into the pump chamber and discharged from the exhaust port Micro pump is mainly used for medicine gas analysis sampling instrumentation and other fields Completely maintenance free and no oil pump do not pollute the transmission medium Small stable and reliable hand held instrument for pump priming low noise low power consumption Especially suitable for high negative environmental requirements Specification Operating voltage DC9V 14VRated voltage DC 12VCurrent Rating 500mAPower Rating 6WSuction capacity 5L minVacuum degree 65kpaMaximum pressure 120kpaNoise 60dbPackage includes 1pc Vacuum suction pump Details pictures
