5.3 MODE OF OPERATION
The double diaphragm pump is driven with compressed air. A pneumatic manifold
alternates in supplying two diaphragms with compressed air. Diaphragm motion is
created in this manner. The product is thus sucked in and displaced again. A series of four
non-return valves prevents the liquid from owing back, thus producing the suction and
delivery phases in each pumping chamber, and generating the pumping eect.
