Air Operated Double Diaphragm Pump is a special type of pneumatic displacement pump, that utilize a pressure differential in the air chambers to alternately creat suction and positive fluid pressure in the fluid chambers. Valve checks ensure a positive flow of fluid. Pump cycling will begin as air pressure is applied, and it will continue to pump and keep up with the demand. It will buid and mainain line pressure and will stop cycling once the maximum line pressure is reached and will resume pumping as needed.Diaphragm Moved From The Right To The Left1. The diaphragm pushes the right Actuator Pin(A) mechanically moving the spool (B) to the left.2. Compressed air flows to the right end of pilot air valve, pneumatically moving the spool (B) to the position shown.3. Compressed air also flows to the large end (right end) of the Major Air Valve, acting on the right side of piston (F) to push piston (F) & spool (E) to the left and holds them in position because the area of the right s...
