Advantages of an Air-Operated Double Diaphragm Pump

What are the main features and benefits of an AODD pump?

• AODD pumps are essentially leak-free. Leakage can only happen if one or both of the diaphragms fail because there are only stationary seals between the wetted portions and the outside environment.
• As part of a general maintenance program, diaphragms should be replaced regularly, according to the manufacturer’s recommendations.
• Diaphragms suffer less wear in an AODD pump than those in a mechanically driven diaphragm pump because of the benefit of pressure balancing by the compressed air supply.
• AODD pumps are capable of handling abrasive, highly viscous fluids, sludge or slurries. They are also perfect for fluids that are sensitive to shear because of their gentle pumping action.

What Makes an AODD so Special?

An air-operated double diaphragm pump has a lot of advantages over other pump designs. Below we list out some of the advantages of AODD pumps over other pump types.

Advantages include:

No Electricity: These pumps operate via compressed air. This means that they can be utilized in hazardous regions or other places where an electrical supply is not appropriate.

Simplicity: AODDs are simple to install and run because they don’t need intricate wiring or electrical control. They are actually considerably simpler to use than many other kinds of pumps.

Run Dry: AODD pumps can run dry without causing any problems or harm to the pump. Other pump types must always be primed and must not run dry in order to avoid damaging the entire pump or some of its components and necessitating an expensive rebuild.

Viscous liquids: Air-operated double diaphragm pumps can handle a variety of fluid viscosities. Having a pump that can transport both high and low-viscous materials means that a pump can be used for a variety of tasks.

Abrasive Materials: An AODD pump may process corrosive or abrasive fluids, as well as more solid or powdered solids, in the same way as it can handle low and high viscosities.

Safety: All of the above combined, also means that an AODD pump is a great option when pumping volatile or dangerous liquids.
