The ARO PD05P-BRS-PAA-B is a 1/2" air-operated double-diaphragm (AODD) pump from ARO's compact 1/2" non-metallic series — self-priming, run-dry capable, and rated to about 14.4 GPM on compressed air up to 100 psi.
This build runs an all-polypropylene wetted path — fluid caps, manifold and seats — with Santoprene diaphragms and Santoprene check balls. Santoprene is a tough, value-oriented elastomer with good general chemical compatibility, well suited to water-based and mildly aggressive fluids. Bolted construction keeps the fluid path leak-tight, and ARO's patented unbalanced air valve is designed to resist stalling and ice-up.
It is a sensible fit for general transfer in water treatment, wastewater, chemical feed and industrial maintenance. Not sure this build suits your fluid? Send us your application details and we'll point you to the right part number.
