ARO PD20A-AAS-GGG-B 2in Aluminum AODD 120 PSIG Diaphragm Pump

The Ingersoll Rand ARO PD20A-AAS-GGG-B is a new, factory-assembled 2-inch Expert Series air-operated double diaphragm (AODD) pump with an aluminum center section and aluminum fluid chambers, rated for a maximum working pressure of 120 psig (8.3 bar) as confirmed on the nameplate. Decoding the model number: PD20A = 2-inch Pro/Expert Series metallic AODD pump; the first "A" in AAS = aluminum air valve/center section; second "A" = aluminum fluid chambers; "S" = stainless steel hardware; "GGG" = Buna-N (nitrile) diaphragms, balls, and seats; "B" = standard baseplate-mount configuration. The pump delivers up to approximately 66 GPM (250 LPM) at 0 psig back-pressure and is self-priming, capable of running dry without damage, and certified CE and ATEX (Ex) for use in hazardous-location environments as shown on the carton label. This model is widely deployed in chemical processing, wastewater transfer, industrial fluid transfer, and general manufacturing where air-driven, seal-less pumping of moderately aggressive fluids is required; it ships with an inline exhaust muffler/filter, 90° NPT exhaust elbow, and documentation pack as visible in the photos.
