PD20A-AAS-AAA-B ARO 2" Aluminum Metallic Expert Series Air Operated Double Diaphragm Pump
P/N PD20A-AAS-AAA-B ARO 2" Aluminum Metallic Expert Series Air Operated Double Diaphragm Pump
The ARO PD20A-AAS-AAA-B is a 2-inch metallic Expert Series air-operated double-diaphragm pump designed for dependable fluid transfer in industrial, process, and general-purpose applications. Its durable aluminum construction with stainless steel hardware, combined with Santoprene diaphragms, Santoprene valve balls, and stainless steel seats, provides excellent mechanical durability, flex life, and abrasion resistance for handling a wide variety of general utility fluids, mild chemicals, and slurries.
The 2-inch NPTF - 1 threaded connection (with a 3/4" NPTF air inlet) provides straightforward installation, while the bolted construction supports reliable, leak-resistant fluid handling and convenient serviceability. This pump is well suited for fluid transfer, filling, recirculation, batching, and handling suspended solids.
Application suitability should be confirmed based on the specific fluid, temperature, viscosity, chemical compatibility, solids content, and operating conditions. Aluminum-wetted models are not for use with halogenated hydrocarbon solvents or food products for human consumption.
