PD20A-ASS-STT-B ARO 2" Stainless Steel Expert Series Air Operated Double Diaphragm Pump
P/N PD20A-ASS-STT-B ARO 2" Stainless Steel Expert Series Air Operated Double Diaphragm Pump
The ARO PD20A-ASS-STT-B is a 2-inch Metallic Expert Series air-operated double-diaphragm pump engineered for high-volume, chemical-resistant, and dependable fluid handling in demanding industrial applications. Featuring 316 stainless steel fluid caps, manifolds, seats, and hardware paired with an aluminum center body and PTFE valve balls and diaphragms (with Santoprene® backing), it offers exceptional chemical compatibility and long service life.
Its bolted construction ensures leak-free fluid containment and simplified field maintenance. This configuration is well suited for chemical processing, acid and caustic transfer, 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.
