Double Air Driven Diaphragm Pump Introduction

Air diaphragm pump(also know as a Membrane pump, air operated double diaphragm pump(AOOD) or pneumatic diaphragm pump)that uses a combination of the reciprocating action of a rubber,thermoplastic or diaphragm and suitable valves either side of the diaphragm (check valve,butterfly valves,flap valves,or any other form of shut-off valves) to pump a fluid.

The diaphragm pump offers high volume delivery even at low air pressure and a b road range of material compatibility options available.Refer to the model and option chart.The pump is provided with the modularized air motor and fluid section.

The air operated diaphragm pump alternately generates the intake fluid pressure and positive fluid pressure in the fluid chamber by using the pressure difference in the air chamber. The ball valve can ensure the forward 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 build and maintain line pres -sure and will stop cycling once maximum line pressure is reached (dis -pensing device closed) and will resume pumping as needed.
