Operation Principles of AODD Pump

Atmospheric pressure pushes the liquid to the suction side. Acting as a separation membrane between the compressed air add liquid, the elastomeric diaphragm applies pressure to the liquid column, while also balancing the load in order to remove mechanical stress from the diaphragm.

As an ISO certified company, our engineering intellect and manufacturing processes pups second to none. Also known as air-operated double diaphragm pumps, they are used for endless applications in mining, pmps and general plant service.

DM-2 Diaphragm Monitor System. Views Read Edit View history. When the pressurised diaphragm, Diaphragm A, reaches the limit of its discharge stroke, the air valve redirects pressurised air to the backside of Diaphragm B. This allows them to be used without added lubrication in contact with the air, so the compressed air produced can be guaranteed clean. The air valve is located In the center section of the diaphragm pump. These diaphragms are connected by a shaft in the center section.

As the pump reaches its original starting point, each diaphragm has gone through one exhaust and one discharge stroke. An air operated double diaphragm pump has two diaphragms. When the volume of a chamber of either type of pump sodd increased the diaphragm moving upthe pressure decreases, pumsp fluid is drawn into the chamber [3].

From Wikipedia, the free encyclopedia. This allows the fluid to flow along the ball valve into the liquid chamber. Center port diaphragm pumps have the suction side and discharge side orientated towards the front or back centered between the two ends of the pump.

They do not leak, offer little friction, and can be constructed for low pressure sensitivity. Compared to other compressors, these pumps are quiet, cheap and, most importantly, have no moving parts in the airstream.
