Comparing Different AODD Variants: The Proof is in the Pump

The benefits of using air-operated double-diaphragm (AODD) pumps are not unheard of. However, figuring out which one in the market best suits your needs might be a cumbersome activity. This article presents the results of headto-head comparisons between the top AODD pumps and the final data acquired during those tests. The results will help illustrate the impact differing ADS technologies have on air consumption, energy use and overall flow rate.
