AODD pump and its industry application
                     AODD pump and its industry applica
tion
Air-Operated Double-Diaphragm (AODD) pumps use 
compressed air as a power source to move fluids. A particular 
amount of pressure (measured in pounds per square inch) and 
air volume (measured in cubic feet per minute) are needed to 
operate an AODD pump. AODD pumps are capable of 
performing in most applications under the most challenging 
conditions. When in operation, there is air pressure on the 
entire surface of the diaphragm, which removes mechanical 
stress from the operation, keeping it in a balanced condition. As 
a result, the diaphragms in an AODD pump last longer as 
compared to mechanically operated pumps. The simplicity of 
the design of AODD pumps allows operators to find the correct 
pressures and flows for an optimised operation. Since AODD 
pumps are operated without electricity, there are no chances of 
sparks or electric shocks during operation. This makes AODD a 
safer pump alternative.
Where is the AODD pump used?
AODD pumps are used in various industries. They are very 
popular in the wastewater and sewage treatment industries. 
Because of their self-priming capabilities, AODD pumps are 
also a natural choice in industries where one needs to lift 
fluids from a lower level. At the same time, AODD pumps are 
also used in sectors where fluids are to be pumped over long 
distances.
Advantages of AODD Pumps
Long life: Since AODD pumps run on air pressure, there are 
only a few wet parts. The dry operation allows the pump to 
run for a long time without any significant wear and tear.
Self-priming: Since AODD pumps are capable of evacuating 
air from the suction line and starting pumping without the 
need for any manual priming, they are considered reliable, 
especially when the operator has to work with a suction line 
that may contain gases or air.
Can handle various kinds of fluids: AODD pumps can 
work with fluids of different densities and viscosities, such as 
solid-laden fluids, abrasive liquids, and corrosive chemicals.
Adjustable flow rates: As mentioned above, AODD pumps 
allow users to adjust flow rates (between 19 and 1,100 litres 
per minute) and pressure by regulating the air pressure 
supplied to the pump. This feature comes in handy for 
industries that require operators to constantly change 
pressure and flow owing to, say, changes in the texture and 
density of fluids.
Easy installation: Because of the simple design of two 
diaphragms that perform under compressed air and a 
minimum number of moving parts, AODD pumps are compact 
and easily portable. These pumps do not require a fixed 
power source, which adds to their flexibility.
Safety: AODD pumps are designed to offer easy leak 
detection and containment. And if the diaphragm ruptures, 
the fluid is contained within the pump chamber, eliminating 
any risk of spilling.
Versatility: AODD pumps can be customized based on the 
requirements of various operators. From clean water to harsh 
chemicals and sewage, they can be used with various kinds of 
fluids. It is to be noted here that the pump material is very 
important when it comes to operating different kinds of fluids. 
For example, while handling water, a metallic pump may react 
to strong acids, so a plastic pump would be a better idea.
Industries that use AODD pumps include automotive, 
ceramics, chemicals, construction, marine, mining, oil and 
gas, paints and coatings, pulp and paper, and water 
treatment.
However, choosing the right AODD manufacturers in a 
market full of suppliers can be really challenging for 
operators across industries. While making the decision, it's 
important to consider the reliability, lead time, maintenance 
package, after-sales service, and on-time delivery records of 
the suppliers.
With a legacy dating back to 1965, Sandpiper has made a 
name for itself as a renowned supplier of superior, high-
quality, robust, reliable air-operated double diaphragm 
pumps. As the top producer of submersible pumps in 
Ahmedabad, Sandpiper is committed to offering its 
customers not just the best fit based on their requirements 
but also top-notch after-sales service.
Operating under the IDEX India wing, Sandpiper takes 
pride in offering multiple solutions from its 
comprehensive portfolio of value-driven products. 
Sandpiper AODD pumps are durable, self-operated, self-
primed, and abrasion-resistant. They offer excellent solid 
holding capability, and they come with a non-stalling air 
valve guarantee. AODD pumps can be easily moved 
around as they are light in weight. At the same time, 
they are capable of handling very high pressure.
AODD pumps are an alternative to centrifugal pumps and 
are used in a variety of industries. Here are some 
benefits of Sandpiper AODD pumps:
• They can be submerged completely while maintaining 
safety protocols.
• They do not require electricity and can be fully 
grounded.
• They can be deadheaded safely without any pump or 
product damage.
• They offer flow and pressure control without any 
complex or sophisticated parts or mechanisms.
