-Micro-pump is powered miniature DC electric motor drive, drive internal mechanical eccentric eccentric movement, driven by an eccentric movement inside the diaphragm reciprocates. Whereby the pump chamber fixed volume of surroundings compression (compression suction port is closed, the exhaust interface is formed to open somewhat positive pressure), stretching (compressed exhaust interface is closed, a poor pressure sucking mouth open up), the pumping surroundings Dc Vacuum Pump intakes with the outside atmospheric pressure difference, at a pressure difference, the gas pressure (suction) in to the pump chamber, and discharged from the exhaust slot.
-Micro-pump is principally used for medication, gas evaluation sampling, instrumentation and additional fields. Completely maintenance-free, no oil pump, do not pollute the transmission moderate.
-Small, stable and dependable, hand-kept instrument for pump-priming, low noise, low power consumption. Especially -appropriate for high unfavorable 
environmental requirements.
