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