Description

P/N PD20A-AAP-GGG-B ARO 2" Aluminum Metallic Expert Series Air Operated Double Diaphragm Pump

The ARO PD20A-AAP-GGG-B is a 2-inch Metallic Expert Series air-operated double-diaphragm pump engineered for high-volume, dependable fluid handling in demanding industrial and utility applications. Featuring an all-aluminum casing paired with plated steel hardware, aluminum seats, and durable Nitrile (Buna-N) valve balls and diaphragms, it provides robust performance for petroleum, fuel, and oil-based fluid transfers.

Its bolted construction ensures leak-free fluid containment and simplified field maintenance. This configuration is well suited for industrial fluid transfer, circulation, filling, batching, fuel handling, and pumping 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.
