PD20A-AAP-AAA-B ARO 2" Aluminum Metallic Expert Series Air Operated Double Diaphragm Pump
P/N PD20A-AAP-AAA-B ARO 2" Aluminum Metallic Expert Series Air Operated Double Diaphragm Pump
The ARO PD20A-AAP-AAA-B is a 2-inch Metallic Expert Series air-operated double-diaphragm pump engineered for high-volume, dependable fluid handling in industrial and process applications. Featuring an all-aluminum casing paired with plated steel hardware and durable Santoprene® internals (seats, balls, and diaphragms), it offers exceptional mechanical fatigue resistance and long service life.
Its bolted construction ensures leak-free fluid containment and simplified field maintenance. This configuration is well suited for industrial fluid transfer, 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.
