HS430S High Pressure Bolted Metal SECTION 3 HOW IT WORKS – AIR-OPERATED DOUBLE-DIAPHRAGM PUMP The Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show flow pattern through the pump upon its initial stroke. It is assumed the pump has no fluid in it prior to its initial stroke. FIGURE 1 When air pressure is supplied to the FIGURE 2 Once the shaft has reached the FIGURE 3 At completion of the stroke, the air... -

HS430S High Pressure Bolted Metal SECTION 6 SUGGESTED INSTALLATION, OPERATION, MAINTENANCE AND TROUBLESHOOTING The best choice possible will be a site involving the shortest and ilden pumps are designed to meet the performance requirements of straightest hook-up of suction and discharge piping. Unnecessary elbows, even the most demanding pumping applications. - Page 11 HS430S High Pressure Bolted Metal SUGGESTED INSTALLATION, OPERATION, MAINTENANCE AND TROUBLESHOOTING restarted by reducing the fluid discharge pressure or increasing the NOTE: In the event of a power failure, close the shut- air inlet pressure. The Wilden High Pressure Pumps run solely on off valve if you do not want the pump to restart when the compressed air and does not generate heat, therefore your process power returns.
