Description of the pump

Operation
	ADB BOXER air operated diaphragm pumps are oscillating positive displacement pumps with two back to back pump chambers. These are each divided by a diaphragm into an air and a fluid area. Both diaphragms are connected by a common shaft with the effect that during one pumping stroke medium is pressed out of the one pump chamber ,while medium is being drawn into the other pump chamber . The two adjacent drawings describe the sequence of a complete cycle consisting of a suction and pressure strokes of an air operated diaphragm pump. In the drawings the medium is colored in blue while the air in red.
STEP 1
	By filling the left hand air chamber with air (red) the left hand diaphragm is pushed outwards. This pulls the inner cap on the right hand diaphragm to the initial position carrying the diaphragm along. The valve ball (1) is drawn out of it’s position the medium (blue) flows into the right hand pump chamber. At the same time valve ball (2) is seated in a closed position by the vacuum. The right hand pump chamber fills up with medium (blue)
STEP 2
	The control valve (3) switches over the air flow into the right hand air chamber (red). The left hand air chamber is exhausted. The suction process (see step 1) now takes place in the left hand pump chamber. Medium (blue) is pressed out of the right hand pump chamber , valve ball (1) is pressed down and closes while valve ball (2) opens allowing the medium to flow to the outlet.
