How Do Air-Operated Diaphragm Pumps
Work?
Air-operated diaphragm pumps, also known as AODD pumps, are trusted pieces of
equipment used in a variety of industries. Their robust design allows them to handle a
wide range of fluids, from clean and clear liquids to highly viscous, abrasive, or
hazardous materials. Understanding how these pumps work can help users maximize
their benefits and maintain their efficiency.
Basic Principles of Operation
An AODD pump operates on a simple yet effective principle. It consists of two pumping
chambers, each with a diaphragm, and an air distribution system that directs
compressed air alternately to each diaphragm. Here's a step-by-step breakdown of the
process:
Air Supply: Compressed air enters the pump through an air inlet, moving into the air
valve which directs the air to one of the diaphragms.
Diaphragm Movement: The air pressure pushes the diaphragm outward, creating a
suction effect in the opposite chamber. This suction pulls the fluid into the chamber
through an inlet valve.
Displacement: As one diaphragm moves outward, the other diaphragm is pulled
inward. This movement pushes the fluid in the second chamber out through an outlet
valve.
Valve Operation: The pump has check valves at the inlet and outlet to ensure one-way
flow of the fluid. When the diaphragm moves, these valves open and close automatically
to allow fluid to enter and exit the pump.
Continuous Cycle: The air valve switches the air supply between the diaphragms,
creating a continuous pumping action. This cycling can occur rapidly, with some pumps
capable of thousands of cycles per minute.
Advantages of AODD Pumps
Versatility: AODD pumps can handle a wide variety of fluids, including those with high
viscosity, shear-sensitive products, or fluids containing solids.
Self-Priming: These pumps can self-prime and run dry without damage, making them
ideal for applications where fluid supply may be inconsistent.
Safe for Hazardous Materials: Since the pump is air-operated, there is no risk of
sparks, making it safe for transferring flammable or hazardous materials.
Ease of Maintenance: AODD pumps have a simple design with fewer moving parts,
which makes them easier to maintain and reduces downtime.
Applications of AODD Pumps
AODD pumps are used in numerous industries, including:
Chemical Processing: For transferring chemicals, acids, and solvents.
Food and Beverage: For handling food products, syrups, and beverages.
Pharmaceuticals: For transferring ingredients and finished products.
Mining and Construction: For dewatering and slurry transfer.
Paint and Coatings: For moving paints, varnishes, and adhesives.
