-Micro-pump is powered miniature DC motor drive, drive internal mechanical eccentric eccentric motion, driven by an eccentric Dc Vacuum Pump motion within the diaphragm reciprocates. Whereby the pump chamber fixed volume of air flow compression (compression suction slot is shut, the exhaust slot is produced to open slightly positive pressure), stretching (compressed exhaust port is closed, a poor pressure sucking mouth open up), the pumping air flow intakes with the exterior 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, and no oil pump, do not pollute the transmission 
moderate.
-Small, stable and reliable, hand-held instrument for pump-priming, low noise, low power consumption. Especially -appropriate for high unfavorable environmental requirements.
