Air Operated Diaphragm Pumps

Air Operated Diaphragm Pumps, also known as AODD pumps, are a type of reciprocating positive displacement pump that are driven by compressed air rather than an electric motor. Here’s a summary of their importance, function, and applications:

Importance of Air Operated Diaphragm Pumps:

Safe and Clean Operation: With no motors, packing or seals, the AODD pump is less prone to leaking fluid than typical centrifugal pumps. This makes it a good solution when handling volatile, corrosive or dangerous liquids that may cause harm if leaked.

Good Dry Running Capabilities: Unlike other pump types, air operated diaphragm pumps are able to run dry or against a closed discharge without causing immediate damage to the pump.

Self Priming: Air diaphragm pumps are self-priming and therefore have good suction capabilities (up to 8m when wetted) without need for a manual priming device.

Flexible Performance: AODD pumps are versatile in their performance, as to meet exact flow rate or pressure requirements of a particular installation you can simply adjust the air inlet pressure.

Function of Air Operated Diaphragm Pumps:

Flow Control: AODD pumps work by utilizing a balanced magnetic field to generate the rotation of the liquid impeller. It differs from a conventional centrifugal pump, which employs a direct drive connection between the impeller and motor, and incorporates a magnetic field.
Applications of Air Operated Diaphragm Pumps:

AODD pumps are used in a wide range of industries due to their versatility and effectiveness. They are commonly used in:

Water supply systems

Wastewater treatment

Slurry services

Fire protection

Air and gas supply

Vacuum services

Lubrication system

Chemical and oil industries

Fuel handling systems

Power generation

Compressed air and gas services

Steam services

Food processing

Pharmaceutical

Marine systems

Sanitary valve applications

In summary, Air Operated Diaphragm Pumps are integral to the functionality of fluid power systems. They help regulate flow, increase efficiency, reduce waste, and are versatile enough to be used in a wide range of applications.
