ARO PD30P-DPS-KAA-A 3in Non-Metallic AODD Diaphragm Pump Assembly

The ARO (Ingersoll Rand) PD30P-DPS-KAA-A is a new, 3-inch Expert Series air-operated double-diaphragm (AODD) pump assembly with a non-metallic polypropylene wetted body and black acetal/Hytrel center section, assembled in the USA and CE/EAC certified as confirmed by the box label and nameplate. Decoding the part number: PD30P = 3-inch non-metallic (polypropylene) pump body; D = standard duty; P = polypropylene fluid chambers; S = PTFE (Teflon) diaphragms; K = PTFE ball check valves; A = 3/4-inch NPT air inlet; A = standard air valve configuration — making this pump chemically resistant and suitable for aggressive acids, caustics, solvents, and other corrosive fluids. The pump delivers up to approximately 229 GPM (866 LPM) maximum flow and operates on compressed air supply up to 125 psig (8.6 bar), with factory final-test documentation confirming run-in at 85–95 psi and pressure-drop verification at 90 psi; its self-priming, non-sparking, non-electric design suits chemical transfer, drum unloading, filter press feed, and wastewater applications where metallic contact must be avoided. Flanged inlet and outlet connections are 3-inch with bolted polypropylene elbow manifolds and stainless steel hardware visible in photos; the unit ships on its original pallet in the original ARO carton.
