Air Operated Double Diaphragm Pumps

Click image to enlarge

Air operated double diaphragm pumps feature two flexible diaphragms connected by a shaft. As the diaphragms move back and forth, they create a pumping action that draws fluids in and expels them through the pump. Pumping Solutions offers AODD pumps from a range of top diaphragm pump manufacturers, including models with flow rates from 0-300 GPM, and in a variety of materials ranging from Stainless Steel to Polypropylene.

Features and Benefits of Air Operated Double Diaphragm Pumps

Double-diaphragm pumps are highly versatile and designed to handle tough jobs like pumping chemicals, slurry, concrete or barrels of water. They provide an efficient, low maintenance solution for a range of industrial applications including mining, oil & gas, wastewater treatment, pulp and paper, and pharmaceutical. Since AODD pumps use compressed air instead of electricity, they are safe to use with and around hazardous substances. 
Air operated double diaphragm pumps are relatively easy to set up and relocate for different application uses throughout your plant. They are practically leak-free and can run dry since they do not contain internal seals or components that require lubrication.
For the pump function properly, the pressure of the compressed air supply must be equal to or greater than the pressure of the substance being pumped. Double diaphragm pumps are also noisier and create more vibrations than mechanical pumps. Therefore, they should not be used near sensitive machinery or devices.

Choosing The Right AODD Pump

Pumping Solutions is fully stocked and ready to deliver AODD pumps to meet a variety of industry-specific applications.

Wilden 1/2" AODD Pumps

Wilden ½” air diaphragm pumps utilize reciprocating elastomer diaphragms and check valves for pumping fluid, oil, viscous fluids and slurries. The 1/2” air diaphragm pump has excellent suction characteristics for handling a high amount of grit and solids, making it a popular choice for mining applications.

Wilden 1" AODD Pumps

The larger diaphragm opening of the Wilden 1” pump provides for an increased amount of product movement for large jobs. Frequent uses include:
  • Oil sludge
  • Refinery waste
  • Food processing residual
  • Slurry & more

Wilden 1 1/2" AODD Pumps

Wilden’s 1 ½” air diaphragm pump is specifically designed to move, handle and transfer large volumes of viscous bulk fluid products. These pumps have optimized liquid paths to reduce friction and maximize output while transferring harsh chemicals, abrasive fluids and hard-to-transfer liquids.

Wilden 2" AODD Pumps

The large 2” diameter can improve the transfer of sludges, slurries, abrasive fluids, oil and mineral-related products by utilizing simple diaphragm changing capabilities and a leak-free design.

Wilden 3" AODD Pumps

Wilden’s 3” pumps are our highest capacity AODD pumps and can handle sludges, slurries and other liquids with a with high amount of grit and solid content.

AODD Pumps for Efficient and Reliable Fluid Transfer

Double diaphragm pumps are self-priming and typically used in low-pressure fluid transfer applications. They are compatible with dirty, contaminated, and viscous fluids and used for applications such as:
  • Acid transfer metering
  • Food processing
  • Gels, creams, paints, and oils
  • Slurries and sludges
  • Volatile solvents and more
