Pump Operation

a) Chambers are alternately filled and emptied by fluid that is drawn in through a common inlet and discharged through a common outlet.
b)The diaphragms in each chamber are linked by a single shaft, enabling them to move backward and forward in unison.
c) To power pump strokes, the air valve directs compressed air alternately behind each diaphragm.
d)In one of the chambers, the suction stroke of the diaphragm opens the lower ball valve while closing the top one.
e) This allows fluid to be drawn into the chamber via the inlet.
f)The air valve directs air behind the opposite diaphragm, causing the top ball valve to open and the bottom to close. This forces the fluid through the outlet.
g)The same process then occurs in the opposite chamber.
h)When the air valve causes the diaphragm to switch positions, the ball valves open and close and the fluid from the opposite chamber is forced through the outlet.
i) The process then repeats, continuall alternating between each chamber.
