PD20S-ASS-STT-B ARO 2" Stainless Steel Metallic Expert Series Air Operated Double Diaphragm Pump
P/N PD20S-ASS-STT-B ARO 2" Stainless Steel Metallic Expert Series Air Operated Double Diaphragm Pump
The ARO PD20S-ASS-STT-B is a 2-inch Metallic Expert Series air-operated double-diaphragm pump engineered for high-volume, dependable fluid handling in aggressive chemical, pharmaceutical, and industrial applications. Featuring a 316 stainless steel casing paired with stainless steel hardware, 316 stainless steel valve seats, and PTFE valve balls and diaphragms (with Santoprene® backing), it provides superior corrosion resistance and broad chemical compatibility.
Its bolted construction ensures leak-free fluid containment and simplified field maintenance. This configuration is well suited for corrosive chemical transfer, chemical circulation, filling, batching, and handling aggressive fluids with small suspended solids.
Application suitability should be confirmed based on fluid chemical compatibility, operating temperature, viscosity, and process conditions.
