Top 5 Reasons to Use AODD Pump

Air Operated Double Diaphragm pumps were initially announced to the market over 60 years ago and they created a whole new industry! They offered a seal-less, positive displacement alternative to centrifugal pumps and quickly gained traction in the manufacturing world.

Over the past six decades, the market has seen many inventions in AODD pump technology. Stimulating pump design variations and changes to diaphragm creation have given these pumps the edge over alternative pumping methods in liquid transfer applications.

AODD pump (also known as Air operated the double diaphragm pump, pneumatic diaphragm pumps, AODD pumps, AOD pumps) are used for endless applications in mining, industrial and common plant service. Driven only by compressed air, they are especially used where electricity isn’t accessible, or in explosive or flammable areas.

Air operated double diaphragm pump is a type of responding diaphragm pump manufacturers which covers two diaphragms driven by compressed air. Air section with shuttle valve applies air alternately to the two diaphragms, separately diaphragm has a set of check/ball valves.

AODD pump manufacturers are usually used for transfer applications and can grip a wide variety of feeds including sludges, slurries, abrasive and shear sensitive fluids. Although they are robust, reliable and easy to keep they can be noisy, prone to icing, and are limited to low-pressure applications.

MULTIPLE OPTIONS FOR CONSTRUCTION

AODD pumps have found applications in multiple businesses, ranging from chemicals, food processing, paints, electronics, mining and everything in between. Diaphragm pump India come in a range of sizes and resources of construction and their versatility mean there is a pump for every fluid.

Materials of construction include bodies in acetal, aluminum, cast iron, polypropylene, PTFE, Stainless Steel, and Kynar and many elastomers choices. The material and size nominated can be selected to cope with almost any fluid that needs to be pumped.

SIMPLISTIC DESIGN

The simplicity of AODD pumps makes them pleasing to everybody from amateur to professional users. They are best described as a ‘plug in and play’ product because once they are connected to a compressed airline, they effectively take care of themselves; they can run dry dead-head without damage. Their ease of use mutual with a highly effective capability of pumping most materials makes them the pump of choice for many in the industry.

SAFETY

Since AODD pump use compressed air as their only power source, they are intrinsically safe and are available ATEX Certified for use in applications where it is not likely to use electricity or it is dangerous to do so, such as in hazardous or explosive environments or at remote sites.

FLEXIBILITY AND DISCHARGE CAPABILITY

AODD Pump sizes from ¼” to 4” are available giving flow charges between 19lpm and 1,100lpm. With producers offering a range of flexible sizes, users can buy a pump that will give them a perfectly balanced system. To give an idea of what this means in real terms, a ¼” pump will empty an IBC (1,000litres) of water in 53 minutes whereas a 3” pump will take just 1 minute.

Another the attraction of AODD pumps comes from the fact that standard units 1:1 ratio pumps, meaning the air pressure in equals the fluid pressure out giving potential discharge weights of up to 8bar. All this without mentioning the high pressure e.g. 2:1 ratio pumps.

Applications
AODD pumps provide an excellent method for handling for all kinds of liquids, whether thick pastes, solids-laden, aggressive or thin and with poor lubricity. Driven by a constant supply of compressed air, this pump type can be used in explosion-proof areas where highly volatile liquids and gases are present.

Containing few components mean that installation is simple and mean time before failure (MTBF) is extended, thereby contributing to lower maintenance.
