• Description: OOTDTY -Micro-pump is powered miniature for Dc motor , within mechanical eccentric motion, pushed via an eccentric movement contained within the diaphragm reciprocates. -Whereby the chamber fixed quantity of air compression (compression suction port is closed, the exhaust port is shaped to open slightly super pressure), stretching (compressed exhaust port is closed, a damaging pressure sucking mouth open), the pumping air intakes with the exterior atmospheric pressure difference, at a strain difference, the fuel pressure (suction) into the chamber, and discharged from the exhaust port. -Micro-pump is especially used for , fuel evaluation , instrumentation and different fields. -Completely maintenance-free, and no oil do not pollute the transmission -Small, regular and reliable, hand held instrument for pump-priming, low noise, low calories consumption. Especially appropriate for top adverse environmental requirements. Specification: Brand new Type: DC12V Mini Vacuum Operating : DC9V ~ 14V Rated : for Dc 12V Positive pressure: 8000mmHG Negative pressure:-500mmHG Rated Current: 350mA Rated Power: 20W Suction capacity: 8L min Inlet diameter：6mm Outlet diameter: 6mm Vacuum degree: 66kpa Maximum pressure: 120kpa Noise:<60db Size: as picture shows Color: as photo reveals Package include： 1 Micro Vacuum
