REASONS TO USE AND CHOOSE AODD PUMPS

 

Since its invention in 1955 as a mining pump, the air-operated double-diaphragm (AODD) pump has established a well-earned reputation as a technology that's ideally fitted to utilitarian, auxiliary, or basic liquid-handling and transfer applications. AODD pump excels in these sorts of applications because they possess design characteristics that allow them to supply simple, seal-less operation and enable them to self-prime, run dry, achieve suction lift up to 30 feet, resist deadhead pumping conditions, operate while submerged, and pass solids up to three inches in diameter.

 

It didn’t take long for companies to ascertain why these operational characteristics would be highly desirable in many processes applications and why AODD pumps are really true “process” pumps that are capable of performing efficiently, reliably, and safely during a wide selection of critical fluid-handling applications. AODD pump also hit the operational sweet spot in many of the fluid-handling tasks that are prevalent within the chemical-processing industry.

 

In fact, there are four key areas during which AODD pumps will outperform competitive technologies in terms of efficient, reliable, and cost-effective operation. Chemical processors who are looking to optimize their operations would know to consider the benefits that AODD pumps can provide in these areas.

 

Air Operated Double Diaphragm (AODD) pumps were first introduced to the market over 60 years ago and that they created an entirely new industry! They offered a seal-less, positive displacement alternative to centrifugal pumps and quickly gained traction within the manufacturing world.

 

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

As a leading AODD Pump Suppliers and Dealer of industrial pumps and fluid handling systems, they are an authorized distributor for the following brands of AODD pumps: Antliaworks

MULTIPLE OPTIONS FOR CONSTRUCTION

AODD pumps have found applications in multiple industries, starting from chemicals, food processing, paints, electronics, mining and everything in between. Air operated double diaphragm pumps are available a the spread of sizes and materials of construction and their versatility means there's a pump for each fluid.

Materials of construction include bodies in acetal, aluminium, cast iron, polypropylene, PTFE, chrome steel and Kynar and lots of elastomers choices. The fabric and size selected are often selected to deal with almost any fluid that must be pumped.

 

SIMPLISTIC DESIGN

The simplicity of AODD pumps makes them appealing to everyone from amateur to professional users. They’re best described as a ‘plug in and play’ product because once they're connected to a compressed airline, they effectively lookout of themselves; they will dry out dead-head without damage. Their simple use combined with a highly effective capability of pumping most materials makes them the pump of choice for several within the industry.

SAFETY

Since AODD pumps use compressed gas as their only power source, they're intrinsically safe and are available ATEX Certified to be used in applications where it's impossible to use electricity or it's dangerous to try to so, like in hazardous or explosive environments or at remote sites.

FLEXIBILITY AND DISCHARGE CAPABILITY

AODD Pump sizes from ¼” to 4” are available giving flow rates between 19lpm and 1,100lpm. AODD Pump Manufacturers offering a variety of flexible sizes, users can purchase a pump which will give them a wonderfully balanced system. To offer a thought of what this suggests 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 attraction of AODD pumps comes from the very fact that standard units 1:1 ratio pumps, meaning the atmospheric pressure in equals the fluid pressure out giving potential discharge pressures of up to 8bar. All this without mentioning the high e.g. 2:1 ratio pumps.
