P/N 6661A3-322-C ARO 1" Polypropylene Non-Metallic Pro Series Air Operated Double Diaphragm Pump
The ARO 6661A3-322-C is a 1-inch non-metallic Pro Series air-operated double-diaphragm pump designed for dependable fluid transfer in industrial, general-purpose, and OEM applications. Its durable colorless polypropylene fluid-contact construction, combined with Nitrile diaphragms, Nitrile check balls, and polypropylene seats, provides a strong balance of mechanical durability and chemical resistance for handling petroleum-based fluids, oils, and general industrial media.
The three-piece manifold configuration provides flexible ANSI flange porting options, while the bolted, seal-less construction supports reliable pneumatic operation and convenient serviceability. This pump is well suited for fluid transfer, circulation, filling, batching, and other applications where dependable performance, versatility, and ease of maintenance are important.
Application suitability should be confirmed based on the specific fluid, temperature, viscosity, chemical compatibility, solids content, and operating conditions.
