The Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show ow pattern through the pump upon its initial stroke. It is assumed the pump has no uid in it prior to its initial stroke. FIGURE 1 The air valve directs pressurized FIGURE 2 When the pressurized diaphragm, FIGURE 3 At completion of the stroke, air to the back side of diaphragm A. The diaphragm A, reaches the limit of its discharge the air valve again redirects air to the compressed air is applied directly to the stroke, the air valve redirects pressurized back side of diaphragm A, which starts liquid column separated by elastomeric air to the back side of diaphragm B.
