P/N PD30A-ASS-STT-C ARO 3" Stainless Steel Metallic Expert Series Air Operated Double Diaphragm Pump
The ARO PD30A-ASS-STT-C is a 3-inch metallic Expert Series air-operated double-diaphragm pump designed for dependable, high-volume fluid transfer in industrial, chemical, and demanding fluid-handling applications. Featuring a durable aluminum air motor combined with corrosion-resistant stainless steel wetted components, PTFE valve balls, PTFE / Santoprene® diaphragms, and stainless steel valve seats, it provides exceptional chemical compatibility and structural strength for handling aggressive fluids.
Built for reliable pneumatic operation, this pump features ARO's patented SimulShift™ "unstallable" air valve and Quick Dump™ exhaust technology to eliminate stalling and prevent cold-weather freezing. Its bolted, stall-resistant construction supports reliable, leak-resistant operation and convenient serviceability, offering high-volume delivery even at low air pressure. This pump is well-suited for chemical transfer, processing, recirculation, batching, and other operations where dependable performance and corrosion resistance are essential.
Application suitability should be confirmed based on the specific fluid, temperature, viscosity, chemical compatibility, solids content, and operating conditions.
