3" Air Operated Diaphragm Pump
Blagdon Air-Operated Double Diaphragm (AODD) Pumps provide high performance, reliable solutions for your pumping needs. They specalise in extreme condition environments and applications...keeping your process moving both above and below ground. Their AODD pumps have long been recognised as the "work horse" of the industry for handling difficult liquids at relatively low pressures and flows. The range of applications is virtually limitless!
The pump chambers are alternatively filled and emptied by drawing fluid in through a common (suction) inlet, and out through a common (discharge) outlet. 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.
