12V Mini Vacuum Pump 8L/min High Pressure Suction Diaphragm Pumps with Holder

Description:-Micro-pump is powered miniature DC motor drive, drive internal mechanical 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.Specifi
