AODD Pump Full Form
AODD pump full form is Air Operated Double Diaphragm pump. It is a positive displacement pump that uses compressed air to alternately flex two diaphragms, drawing fluid in on one side while discharging it on the other. No electricity is required, making it inherently safe for hazardous environments.
How an AODD Pump Works
Compressed air enters one air chamber, pushing the diaphragm forward and forcing fluid out through the discharge valve. Simultaneously, the opposing diaphragm retracts, creating suction that draws fluid in through the inlet valve. An air distribution valve automatically alternates the airflow between the two chambers.
Key Advantages Over Other Pump Types
AODD pumps are self-priming, can run dry without damage, handle solids-laden fluids, and are explosion-proof by design. They are easily throttled by adjusting air supply pressure, making them ideal for variable flow applications in sensitive environments.
Industrial Applications
AODD pumps are widely used in chemical transfer, paint and coatings manufacturing, mining slurry handling, wastewater treatment, food processing, and pharmaceutical production. Their ability to handle aggressive, shear-sensitive, or abrasive fluids sets them apart from centrifugal and gear pump alternatives.
Buying Considerations
When buying an AODD pump, evaluate the diaphragm material (PTFE, Neoprene, Santoprene), body material (PP, aluminium, stainless steel), maximum particle size the pump can pass, and ATEX certification if required for explosive atmospheres.
