These Micro Diaphragm Pumps are a series of DC motor pumps with brushless motor. These micro air pumps are offered as a sensible alternative for low cost applications as well as uses requiring short runs. Various voltage options are available to suit specific needs. It is designed based on the positive displacement pumps. It is powered by the rotation of motor. The eccentric vane drives the rubber inside to reciprocate, forming absorbing and discharging force to pump air.
