What is Air Operated Diaphragm Pump?
An air operated double diaphragm pump is a pneumatic device that circulates compressed air back and forth between its two sides using an air valve. Air-operated diaphragm pumps are capable of transporting liquids with low, medium, or high viscosities, as well as liquids containing suspended solids.
How does air operated diaphragm works:
To pump fluids into and out of the pump's fluid chamber, AODD pumps use dual flexible diaphragms mounted to a shared shaft that moves back and forth repeatedly in strokes. This motion generates a vacuum, which draws fluid in through an inlet port.
When the diaphragms are pushed back to their original positions by compressed air, the fluid is expelled from the product chamber through an outlet port. This cycle is repeated while the AODD is in operation, resulting in the pumping action for which this device is famous.
Types of Applications:
Air-operated double-diaphragm pumps (also known as AODD pumps) are becoming increasingly popular in a variety of industries and applications. Because of the wide range of materials from which the diaphragm can be made, combined with the pumps' seal-less design, even aggressive chemicals and acids can be handled.
Positive displacement (PD) air-operated double-diaphragm pumps have two diaphragms that shift the air supply from one fluid chamber to another. Furthermore, AODD pumps are sealless and run on compressed air rather than a traditional motor system, allowing for smooth, leak-free fluid transfer and movement of any suspended solids. As a result, AODD pumps can be used in a variety of processing and treatment applications.
The air operated diaphragm pump design allows it to be used in a variety of industries:
Oils and fuels
Acids and chemicals
Resins, adhesives, paints, and inks
sewage water
Cosmetic and food products
Benefits:
Flexibility:
Manufacturers provide a variety of flexible sizes, allowing users to purchase a pump that will provide them with a balanced system.
Good dry running capabilities:
AODD pumps can run dry without causing any damage or problems. Other pump types must always be primed and must not run dry in order to avoid damaging the entire pump or some of its components and necessitating an expensive rebuild.
A self-priming process:
Self-priming air diaphragm pumps have good suction capabilities (up to 8m when wet) without the need for a manual priming device. As a result, they are frequently chosen for applications where suction conditions are difficult, such as tank and container emptying.
Safety:
The AODD pump is less prone to fluid leakage than typical centrifugal pumps because it lacks motors, packing, and seals. This makes it an excellent choice for handling volatile, corrosive, or dangerous liquids that could cause harm if spilled.
Simplicity:
AODDs are simple to install and operate because they do not require complicated wiring or electrical control. In fact, they are far more user-friendly than many other types of pumps.
