-Micro-pump is Dc Vacuum Pump powered miniature DC engine drive, drive internal mechanical eccentric eccentric movement, driven by an eccentric motion in the diaphragm reciprocates. Whereby the pump chamber fixed level of air flow compression (compression suction slot is shut, the exhaust port is created to open slightly positive pressure), stretching (compressed exhaust interface is closed, a poor pressure sucking mouth open up), the pumping atmosphere 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 medication, gas evaluation sampling, instrumentation and other fields. Completely maintenance-free, no oil pump, usually do not pollute the transmission medium.
-Small, stable and dependable, hand-kept instrument for pump-priming, low noise, low power consumption. Especially -ideal for high bad environmental requirements.
