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 engineered for high-volume, dependable fluid handling in demanding industrial applications. Featuring an all-aluminum casing paired with stainless steel hardware, Santoprene® valve seats, balls, and diaphragms, it provides exceptional chemical resistance and long service life.
Built for reliable pneumatic operation, this pump features ARO's patented SimulShift™ "unstallable" air valve and Quick Dump™ exhaust technology to eliminate stalling and prevent cold-weather freezing. Its bolted construction ensures leak-free fluid containment and simplified field maintenance, making it well suited for industrial fluid transfer, chemical circulation, filling, batching, and handling compatible fluids with small suspended solids.
Application suitability should be confirmed based on fluid chemical compatibility, operating temperature, viscosity, and process conditions. Note: Aluminum-wetted models are not suitable for use with halogenated hydrocarbon solvents or food products intended for human consumption.
