General introduction

Air diaphragm pump is driven by compressed air, Air enters the air valve which will allow pressurized air into one of the two chambers. As the air enters and fills the chamber on the left, the flexible diaphragm expands and compresses the fluid on that side of the diaphragm. This to force the upper valve to open, releasing the fluid into the discharge pipe. It is called the “discharge chamber” at this point of the pumping cycle. At the same time when the discharge chamber is pumping liquid out of the pump, the opposite diaphragm is pulled in toward the center housing by the drive shaft. Negative pressure is generated in that fluid chamber lifting the lower valve which draws fluid into this chamber, this is the “suction chamber” of the pumping cycle.As soon as this “suction chamber” diaphragm makes contact, the air pilot pin is forced across the center housing, air exhausts to atmosphere from the discharge chamber, at the same time compressed air enters the “suction chamber” and the pumping action is reversed. The vacuum side becomes the pressure side and vis versa.
