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. 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. Small, stable and reliable, hand-held instrument for pump-priming, low noise, low power consumption. Especially -suitable for high negative environmental requirements., Weight: 0.69004688006 pounds, Manufacturer: Blisfulhoks
