Air Operated Double Diaphragm (AODD) pumps employ a different sort of pumping principle when compared to standard, more commonly used centrifugal pumps. A centrifugal pump utilizes a mechanically rotating impeller, which is frequently managed by an independent motor, to move fluids. An AODD pump,in contrast, uses air pressure pushed through a collection of air valves to move diaphragms in order to generate a suction and discharge pressure. The AODD pump is a self-contained unit, requiring nothing more than a compressed air line to operate.

Suction and discharge valves are incorporated into the AODD pump system to prevent backflow on the suction cycle and to allow pressure on the discharge cycle.  These valves can either be of the ball check/seat kind or the flap check/seat sort. Usually, the specific type of valves used in an AODD pump system is determined when the pump is being configured by specifying the percentage of solids that will be pumped.

When compressed air enters the main air valve of the AODD pump, it is pushed through additional pilot valves and a spool and sleeve system so that it can exist on both sides of the pump. When one side is pressurized, the diaphragm shifts inside the enclosure in one direction. This diaphragm is connected to a diaphragm rod, which is then fitted to a second diaphragm on the other side of the pump. The second diaphragm is pulled toward the first diaphragm, creating suction in the opposite chamber.

As the diaphragms complete their shift toward one side of the pump, they come in contact with an actuator, which directs a signal to the pilot valve that it should transport air into the other side of the pump. The air invading the first side of the pump then pushes the second diaphragm in the opposite direction, and the process is repeated as communicated above. This entire operation is dubbed a “cycle.”  Depending on the pump size and air pressure, an AODD pump can cycle several times per second. This creates an uninterrupted stream of discharge liquid.

The internal parts of an AODD pump that come into contact with the pumping media can be produced in a widearrayof ingredients to work out chemical compatibility problems.  These components can also be exchanged with others to provide adaptability when changing pumping applications.  There is almost no limit to the media that can be pumped if the appropriate material pieces are selected.

AODD pumps are used mostly where there is limited space and accessibility.  They are also used in areas where there is no electrical power available. Recently, AODD pumps have been manufactured and approved for use on gas well applications, where they can be powered by sweet and sour natural gas.

Air Operated Double Diaphragm (AODD) pumps use a different kind of pumping principle as opposed to standard, commonly used centrifugal pumps. A centrifugal pump employs a mechanically rotating impeller, which is typically managed by an independent motor, to shift fluids. An AODD pump,on the other hand, leverages air pressure directed through an assortment of air valves to move diaphragms in order to make a suction and discharge pressure. The AODD pump is a self-contained unit, requiring nothing more than a compressed air line to operate.

Suction and discharge valves are put together into the AODD pump system to impede backflow on the suction cycle and to allow pressure on the discharge cycle.  These valves can either be of the ball check/seat assortment or the flap check/seat style. Typically, the particular variety of valves included in an AODD pump system is indicated when the pump is being created by identifying the percentage of solids that will be pumped.

When compressed air invades the main air valve of the AODD pump, it is pushed through additional pilot valves and a spool and sleeve system so that it can alternate on both sides of the pump. When one side is pressurized, the diaphragm shifts inside the cavity in one direction. This diaphragm is attached to a diaphragm rod, which is then connected to a second diaphragm on the other side of the pump. The second diaphragm is pulled toward the first diaphragm, creating suction in the other chamber.

As the diaphragms complete their move toward one side of the pump, they come in contact with an actuator, which conveys a message to the pilot valve that it should transport air into the other side of the pump. The air entering the first side of the pump then pushes the second diaphragm in the opposite direction, and the process is repeated as reported above. This finished operation is dubbed a “cycle.”  Depending on the pump size and air pressure, an AODD pump can cycle several times per second. This generates a smooth stream of discharge liquid.

The internal pieces of an AODD pump that come into contact with the pumping media can be produced in a widegroupof ingredients to solve chemical compatibility problems.  These parts can also be exchanged with others to provide adaptability when changing pumping applications.  There is nearly no limit to the media that can be pumped if the right material parts are used.

AODD pumps are employed primarily where there is limited space and accessibility.  They are also employed in places where there is no electrical power available.
