P/N PD20S-ACP-STT-B ARO 2" Stainless Steel / Cast Iron Metallic Expert Series Air Operated Double Diaphragm Pump
The ARO PD20S-ACP-STT-B is a 2-inch Metallic Expert Series air-operated double-diaphragm pump engineered for high-volume fluid transfer, filling, recirculation, and batching in demanding industrial markets such as paint, ceramic, chemical, and oil & gas. Featuring a durable cast iron wetted casing paired with a stainless steel center section, 316 stainless steel valve seats, and PTFE components, it combines rugged structural strength with broad chemical resistance.
Its bolted construction ensures leak-free fluid containment and simplified field maintenance.
Application suitability should be confirmed based on fluid chemical compatibility, operating temperature, viscosity, and process conditions.
