How the double diaphragm system works
The ECO pump is basically two pumps in one. Chambers A&B are alternatively filled and emptied by drawing fluid in through a common inlet (C) and out through a common outlet (D). 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 (E) alternatively behind each diaphragm to power discharge strokes. Pump speed and therefore fluid flow rate can be infinitely controlled by increasing or decreasing air pressure and / or volume. |
Operation sequence
The red 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 (2) to allow liquid to enter the chamber. Ball valve (4) 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 (3) to the liquid outlet (D). This discharge stroke closes ball valve (1) to prevent further liquid entering the chamber. This cycle is repeated to provide a continuous flow to outlet D. |
