P/N 666101-244-C ARO 1" Stainless Steel Metallic Pro Series Air Operated Double Diaphragm Pump
The ARO 666101-244-C is a metallic Pro Series 1-inch air-operated double-diaphragm pump designed for dependable fluid transfer in industrial, chemical-handling, and process applications. Its durable aluminum center body and stainless-steel fluid section, combined with PTFE / Santoprene® diaphragms, PTFE check balls, and 316 stainless steel seats, provide maximum corrosion resistance and chemical compatibility for handling aggressive acids, solvents, and demanding chemical processes.
The single-manifold design provides a compact, streamlined configuration, while the bolted, seal-less construction supports reliable pneumatic operation and convenient serviceability. This pump is well suited for chemical transfer, fluid processing, circulation, filling, and other applications where dependable performance and ease of maintenance are important.
Application suitability should be confirmed based on the specific fluid, concentration, temperature, chemical compatibility, solids content, and operating conditions.
