air-operated double diaphragm (aodd) pump, air operated double diaphragm pump manufacturer
Working Principle
The AODD pump is double pumps in one.
Chambers A & B are alternatively filled and emptied by drawing liquid in
through a common inlet © and out through a common outlet (D). The Diaphragms in
each chamber are connected by a common shaft so that they move., backwards
together. Compressed dry air is directed by the air valve (E) alternatively
behind each diaphragm to power discharge strokes. Pump speed and therefore
fluid flow-rate can be infinitely controlled by increasing or decreasing or
decreasing air pressure and or volume.
Operation Sequence
The Blue arrows show the pump cycle. Fluid
is being drawn into inlet ( c) by the suction stroke of the diaphragm in
chamber B, which opens the ball valve (1) to allow liquid to enter the chamber
,Ball valve (3) is closed by the diaphragm suction.
In chamber (A) air has been applied to the
rear of the diaphragm to force out the liquid in the chamber through the Ball
Valve (4) to the Liquid outlet (d). This discharge stroke closes Ball valve (2)
to prevent further liquid entering the chamber. This cycle is repeated to
provide a continuous flow o outlet D.
Standard AODD pumps are one : One
ratio-maximum outlet pressure never exceed air supply pressure.
