Page 6: Principles Of Operation
SECTION PRINCIPLES OF OPERATION HOW AN AIR OPERATED DOUBLE DIAPHRAGM PUMP WORKS The air-valve directs pressurized air behind the diaphragm on the right, causing the diaphragm on the right to move outward (to the right). Since both the right diaphragm and the left diaphragm are connected via a diaphragm rod, when the right diaphragm moves to the right, the left diaphragm (through the action of the diaphragm rod) moves to the right also. -

Page 19: Pilot Valve Assembly
PILOT VALVE ASSEMBLY To assemble the pilot valve, reverse the order of disassembly. Should process fluid have contact with the pilot valve O-rings, they should be replaced as swelling may occur and cause irregular operation. During assembly, ensure that the open side of the lip-seals are facing outward. Lubrication of the pilot sleeve assembly, with a non-synthetic lubricant, is recommended in order to facilitate re-assembly into the intermediate. -
