["Description:\r\n-Micro-pump is powered miniature for DC motor drive, drive internal mechanical eccentric motion, driven by an eccentric movement inside the diaphragm reciprocates. \r\n-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. \r\n-Micro-pump is mainly used for medicine, gas analysis sampling, instrumentation and other fields. \r\n-Completely maintenance-free, and no oil pump, do not pollute the transmission medium. \r\n-Small, stable and reliable, hand-held instrument for pump-priming, low noise, low power consumption. Especially suitable for high negative environmental requirements. \r\n\r\nSpecification: \r\nBrand new \r\nType: DC12V Mini Vacuum Pump \r\nOperating voltage: DC9V ~ 14V \r\nRated voltage: for DC 12V \r\nPositive pressure: 8000mmHG\r\nNegative pressure:-500mmHG\r\nRated Current: 350mA \r\nRated Power: 20W \r\nSuction capacity: 8L / min\r\nInlet diameter：6mm\r\nOutlet diameter: 6mm \r\nVacuum degree: 66kpa \r\nMaximum pressure: 120kpa \r\nNoise:<60db \r\nSize: as picture shows\r\nColor: as picture shows\r\n\r\nPackage include：\r\n1 x Micro Vacuum Pump"]
