Description: OOTDTY -Micro-pump is powered miniature for Dc motor , inside mechanical eccentric motion, driven through technique of an eccentric movement contained in the diaphragm reciprocates. -Whereby the chamber fixed number of air compression (compression suction port is closed, the exhaust port is shaped to open slightly tremendous pressure), stretching (compressed exhaust port is closed, a harmful pressure sucking mouth open), the pumping air intakes with the outside atmospheric pressure difference, at a strain difference, the gas stress (suction) into the chamber, and discharged from the exhaust port. -Micro-pump is mainly used for , gasoline evaluation , instrumentation and other fields. -Completely maintenance-free, and no oil don't pollute the transmission -Small, regular and reliable, hand-held utility for pump-priming, low noise, low calories consumption. Especially correct for top detrimental environmental requirements.
