Section 1 CAUTIONS—READ FIRST! CAUTION: Do not apply compressed air to the exhaust port — pump will not function. CAUTION: Do not over-lubricate air supply — excess lubrication will reduce pump performance. Pump is pre-lubed. TEMPERATURE LIMITS: CAUTION: Do not exceed 82°C (180°F) air inlet temperature for Pro-Flo V™ models. CAUTION: Always wear safety glasses when operating pump. If diaphragm rupture occurs, material being pumped may be forced out air exhaust. CAUTION: Pumps should be thoroughly ushed before installing into process lines. FDA and USDA approved pumps should be cleaned and/or...

Section 3 HOW IT WORKS—PUMP 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 air to the back side of diaphragm A. The compressed air is applied directly to the liquid column separated by elastomeric diaphragms. The diaphragm acts as a separation membrane between the compressed air and liquid, balancing the load and removing mechanical stress from the diaphragm. The compressed...
