-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 atmosphere compression (compression 
suction port is shut, the exhaust slot is created to open slightly positive pressure), stretching (compressed exhaust slot is closed, a negative pressure sucking mouth open), the Dc Vacuum Pump pumping air flow intakes with the exterior atmospheric pressure difference, at a pressure difference, the gas pressure (suction) into the pump chamber, and discharged from the exhaust port.
-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 reliable, hand-kept instrument for pump-priming, low noise, low power consumption. Especially -suitable for high bad environmental requirements.
