Air operated double diaphragm (AODD) pumps are just really neat things that move liquid from one spot to another. They are friends who are friendishly helpful, guiding liquids where they have to go. In this lesson, we will discuss AODD pumps and how they operate!
AODD pumps are quite flexible as they are capable of pumping various kinds of liquids that range from water to chemicals. In many scenarios, they’re also like superheroes that are ready to save the day. Whether pumping out water from a flooded area or shifting oil from one container to another, AODD pumps can handle it all!
AODD pumps rely on air pressure to run the liquid alternating back and forth, two chambers are used in the pump. That makes them reliable and efficient: They don’t require electricity to operate. This makes them usable in places where there is no electricity or it’s not safe to use any electricity.

One of the nicest things about an AODD pump is that it can be used in lots of different spots. From the factory to the farm, AODD pumps are used for a host of fluid transfer applications. They’re simple to install and maintain, which is why many companies prefer them.

AODD pumps consist of two chambers divided by a flexible diaphragm. When air is forced into one of the chambers, it shifts the diaphragm and moves the liquid out from the other. This basic yet effective technique enables AODD pumps to conveniently transport liquids.

AODDs are popular since they are dependable, effective and simple to operate. They can accommodate many different liquids and can be used in a variety of places. No matter what form of liquid you need to pump-water, oil, or chemicals—an AODD pump is here to help you do the work.
