• Description: -Micro-pump is powered miniature DC motor drive, pressure inside mechanical eccentric motion, pushed by way of approach of an eccentric movement contained in the diaphragm reciprocates. -Whereby the pump chamber constant quantity of air compression (compression suction port is closed, the exhaust port is formed to open barely large pressure), stretching (compressed exhaust port is closed, a harmful stress sucking mouth open), the pumping air intakes with the outside atmospheric strain difference, at a pressure difference, the gas strain (suction) into the pump chamber, and discharged from the exhaust port. -Micro-pump is mainly used for medicine, gasoline evaluation sampling, instrumentation and varied fields. -Completely maintenance-free, and no oil pump, do not pollute the transmission medium. -Small, steady and reliable, hand held machine for pump-priming, low noise, low strength consumption. Especially compatible for top destructive environmental requirements. Specification: Brand new Type: DC12V Mini Vacuum Pump Operating voltage: DC9V ~ 14V Rated voltage: DC 12V Positive pressure: 8000mmHG Negative pressure:-500mmHG Rated Current: 350mA Rated Power: 20W Suction capacity: 8L / min Inlet diameter：6mm Outlet diameter: 6mm Vacuum degree: 66kpa Maximum pressure: 120kpa Noise:<60db Size: as picture reveals Color: as photograph shows Package include： 1 x Micro Vacuum Pump
