7. At the same time the opposite diaphragm is pulled in by the shaft connected to the pressurized diaphragm So diaphragm A is on its suction stroke the air behind diaphragm A is forced out to the atmosphere through the exhaust port of the pump The movement of diaphragm B away from the center block of the pump creates a vacuum within chamber A The vacuum force sucks the fluid into the inlet manifold forcing the inlet valve ball off its seat The fluid is free to move past the inlet valve ball and fill liquid chamber A MIDDLE STROKE When the pressurized diaphragm diaphragm B reaches the limit of its discharge stroke the air valve redirects compressed air to the back side of diaphragm A The pressurized air forces diaphragm A away from the center block while at the same time the connected shaft pulls diaphragm B to the center block Diaphragm A is now on its discharge stroke Diaphragm A forces the inlet valve ball onto its seat due to the hydraulic forces developed in the liquid chamber and manifold of the pump These same hydraulic forces lift the discharge valve ball off its seat while the opposite discharge valve ball is forced onto its seat forcing the fluid to flow through the pump discharge The movement of diaphragm B toward the center block of the pump creates a vacuum within liquid chamber B Atmospheric pressure forces the fluid into the inlet manifold of the pump The inlet valve ball is forced off
