A pump is most likely an essential component in various industrial processes. Choosing the proper pump can help you optimize your operations and reduce downtime, saving you both time and money. With so many pumps on the market, it can be difficult to obtain the information you need to make the best decision. However, you can choose AODD Pump as they has shown to be a top choice in terms of reliability, durability, and versatility. Here we’ll go through the advantages of AODD (Air-Operated Double Diaphragm) pumps.
The Working Mechanisms of Air-Operated Double Diaphragm Pumps
Air-operated double diaphragm pumps are a form of positive displacement pump that operates on compressed air. An AODD pump uses compressed air that enters an air motor and pushes a diaphragm, ultimately pushing the liquid out of it. The pushed diaphragm is attached to a shaft, which pulls the opposite diaphragm, creating a hollow on the other side and drawing in the liquid.
One-way valves, such as a ball valve or a flap valve, are located at the bottom and top of the two cavities. So, when a cavity is closed, the liquid is pushed up and out, and when it is opened, the liquid is sucked in. This will then alternate between shutting the cavity on one side and opening the other.
Advantages of Using AODD Pumps
Capable of running dry
AODD pumps can run dry for lengthy periods without damaging the pump or its components. Pumps frequently run dry, notably in sump dewatering, tanker unloading, and tank over applications. Nonetheless, running dry can damage other types of positive displacement pumps and limit their service life.
Easy to install
Pump installation is straightforward and cost-effective because no power is required, eliminating the need for additional certifications, costly permits, and explosion-proof motors.
To function properly Air-Operated Double Diaphragm pumps only require an air supply to power the pump. The pump can be regulated via a valve on the fluid discharge or by controlling the air entering the pump. Accessories, such as filter/regulator units, are fairly priced and simple to install on the pump.
They are portable
Pumps can be lightweight and portable, depending on their size and material. Some plant managers cart-mount pumps to improve mobility and application variety.
Safe deadheading
Deadheading happens when the fluid pressure equals the air inlet pressure that drives the pump. When a valve on the pump’s fluid side is closed, the pump will develop pressure until it equalizes and then stops pumping. When the valve on the pump’s discharge fluid side is opened, the pump will resume pumping.
However, many other pumping systems necessitate specialized controls or circulation loops to enable the pump to deadhead. Air-Operated Double Diaphragm pumps are an excellent choice for intermittent applications that require frequent deadheading.
Not shear the finished product
Air-Operated Double Diaphragm pumps do not froth or separate the product being pumped. This is especially important when pumping products that can be altered or destroyed if sheared. Many paints and varnishes, for example, require a shear-sensitive pump to ensure that the products do not change during transfer. Other pumping methods, such as centrifugal and gear pumps, can shear goods.
Outstanding chemical resistance
AODD pumps can be made from a variety of materials and can handle virtually any fluid. Many pumps feature wetted component materials such as stainless steel, Alloy C, cast iron, aluminum, polypropylene, PVDF, and acetal. They can also be customized. So, you can choose a unit that matches your chemical requirements.
Temperature resistance
Air-Operated Double Diaphragm pumps can withstand temperatures as high as 220 degrees Fahrenheit and probably higher. They can also withstand freezing conditions.
No electricity needed
Air-Operated Double Diaphragm pumps run on compressed air, not electricity, and can be grounded for safe and reliable operation in explosive settings. This is especially important when pumping flammable chemicals or when the pump is in an area with fumes.
Can handle different liquids
Air-Operated Double Diaphragm pumps are versatile enough to handle very viscous fluids, abrasive slurries, powders, sensitive chemicals, and solid-bearing liquids. They can be used for a wide range of fluid transfer purposes.
Durable
Air-Operated Double Diaphragm pumps are sturdy and long-lasting. They are simple to maintain and can last longer than some other pumps.
Applications for AODD Pumps
Air-Operated Double Diaphragm pumps are commonly utilized in mining operations to dewater and handle tough slurries. Other industries and applications that can benefit from air-operated double-diaphragm pumps include as follows:
-
Oil and Gas industry
-
Water and wastewater treatment
-
Food and beverage industry
-
Chemical processing
Wrapping Up
Choosing the correct pump for the right application goes a long way toward assuring less downtime, fewer maintenance costs, and improved energy efficiency. From the abovementioned advantages, you can be assured that the AODD Pump is one of the better options available in the majority of applications.

Frequently Asked Questions
Where do Aodd pumps find application?
Air-Operated Double Diaphragm pumps are typically utilized in transfer applications and can handle a wide range of fluids, including sludges, slurries, abrasive, and shear sensitive fluids. Although they are strong, dependable, and simple to maintain, they can be noisy, prone to icing, and are only suitable for low pressure applications.
Is a diaphragm pump capable of lifting water?
Diaphragm pumps can transmit a wide variety of chemicals, including most acids and alkalis, solvents, petrochemicals, and even water.
Is there positive displacement in an AODD pump?
Yes! Air-Operated Double-Diaphragm (AODD) pumps are a type of positive-displacement reciprocating pump. Upon completion of each stroke, they displace fluid from one of its two liquid chambers.
What does an Air-Operated Double Diaphragm pump’s air valve do?
The core component of an air-operated double diaphragm pump is the air valve, which directs compressed air from the air intake to the region behind the diaphragms, where the diaphragm pushes the air out of the pump’s center and toward its exterior.
What are the advantages of AODD Pumps?
Air-Operated Double Diaphragm pumps provide distinct advantages over other pump technologies, making them the obvious choice for many of the world’s most difficult applications.
AODD pumps have a wide range of applications since they can handle anything from water to solids-laden slurries, including volatile and toxic liquids. Their versatility enables a single pump to handle a variety of applications without the need for costly motor drives or important sizing considerations.
What Is the Cost of AODD Pumps?
The cost of an AODD pump might vary substantially depending on the building materials used. Overall, AODD pumps are substantially less expensive than other pumping methods. However, pricing is not the only consideration when it comes to air-operated pumps. Spending a little extra money up front pays returns later on when picking the best AODD pump.
