Main Applications For Air Operated Diaphragm Pump


RONGPENG Air Operated Diaphragm Pump A-25

Motor-driven diaphragm pumps are often used for metering, dosing or dispensing applications but AODD pumps tend to be general workhorse devices, typically used in transfer applications. They are relatively low cost and reliable; they can be run dry and can pump dirty/contaminated liquids.

The following table lists some typical applications of Air Operated Double Diaphragm Pumps:

(Can operate in classified/hazardous areas) 

Dewatering above and below ground sites and quarries

Transferring abrasive slurries and sludge mixtures

Dosing reagents

Transferring solvents for separating minerals from ore

Transferring fuels for vehicles and equipment 

(Can pump low to very viscous solutions, and capable of low shear / gentle fluid transfer)

Transferring, dispensing and dosing paint, ink and dyes

Feed pump for spray guns

Flush/clean paint lines with solvents

(Excellent chemical resistance with corrosive/ hazardous chemicals)

Loading and unloading tankers, totes and barrels

Portable utility pump

Batching/dosing chemicals

Electroplating and Anodizing

Replenishing chemicals in plating and metal finishing tanks

Agitation of cleaning solutions

Circulation of liquid to avoid sedimentation

Filtration (when critical purification is required for high quality parts)

Offloading corrosive, solid laden waste

Pulp and Paper

Printing inks


Kaolin clay

Bulk transfer



Oil and Gas
(Can operate in classified/hazardous areas)

Settling pond transfer

Oils and glycol transfer


Filter press

Bulk transfer

Water / Waste Water Treatment

Transferring solid laden media
