Why Motion for Diaphragm Pumps & Accessories?

Air Operated Double Diaphragm (AODD) Pumps are positive displacement pumps in which two diaphragms are mechanically linked together and forced by air to shift, causing flow in and out through check valves which capture and release the liquid from the chambers that the diaphragms act upon. These pumps are portable and versatile pumps used in a variety of applications where air is available to drive the pump.
