How Sandpiper AODD Pump Works
Working Principals of AODD Pump
Typical sandpiper AODD Pump Chambers are alternatively filled and emptied by drawing fluid in through a common suction manifold and out through common discharge manifold. The diaphragms in each chamber are linked by a common shaft, so that they move backwards and forwards in unison. Compressed air is directed by the air valve alternatively, behind each diaphragm, to power discharge strokes. Pump speed, fluid output and pressure (or head) is controlled by increasing or decreasing the flow of compressed air to the pump.
