Understanding the benefits of AODD pumps

Your business needs to implement a pump system that can draw fluids from one location to another. You aren't sure what type of pump is right for the job, but you are considering an AODD pump (or air operated double diaphragm pump). You are wondering what the benefits of these types of pumps are and whether or not an AODD pump is the correct choice for your application.

How AODD Pumps Work

At Global Pumps, we are happy to help you come to a final decision about which type of pump is right for you. To start, let's review what AOD pumps (air operated diaphragm pumps) actually do. These mechanisms are classified as 'positive displacement pumps' which essentially means that they use air to get fluids where they need to go.

In a positive displacement AOD pump, one diaphragm in the pump is an expanding cavity, used to suction and 'trap' fluid into one side of the pump. The other diaphragm is used to discharge the fluid from the pump mechanism. Compressed air travels from one side of the pump to another, constantly emptying one of the diaphragms while the other fills with fluid. Click here to watch a short video on how AODD pumps work.

The Advantages of the AODD Pump Mechanism

As you can see, the primary positive displacement mechanism that allows AODD pumps to work is a fairly simplistic one. Using air and little else, the mechanism can pump fluid from one location to another with consistent flow rate and reliable efficiency. The question, though, is whether or not an AODD pump is the right choice for your purposes? Ultimately, the answer to that question will depend on the application you intend to use the pump for, as well as upon your required flow rate. However, here are some of the major benefits of the AOD pump mechanism that appeal to businesses and corporations across many industries.

• Inexpensive to Repair: One of the factors that almost all clients love about AOD pumps is that they are so simple to service and repair. Unlike some other pump mechanisms, air operated diaphragm pumps boast an incredibly simple design, with few moving parts and almost no 'high tech' components. As a result, even when AODD pumps get clogged or break down, they are easy and inexpensive to repair or replace.
• Flexibility of Use: AODD pumps are used so widely largely because they are so versatile. An air operated double diaphragm pump can be used to pump virtually any type of fluid—regardless of viscosity, corrosiveness or other properties. Diaphragm pumps are also capable of handling fluids with solids in them, which makes them ideal for dewatering applications.
• They Are Available in a Range of Sizes and Materials: It's not uncommon for AOD pumps to be thought of only for jobs requiring minimal flow rates or moderate pressure. However, at Global Pumps, our diaphragm pumps are available in a range of sizes. Maximum flow rates on our models range from 19 litres per minute to 2,000 litres per metre while maximum pressure goes as high as 8.7 bar.
