1" Series Non-Metallic | ARO Pumps & Parts

ARO 1 inch Series non-metallic diaphragm pumps offer a versatile air-operated solution for chemical transfer, process circulation, unloading, and general industrial fluid handling. Their non-metallic wetted construction can provide useful corrosion resistance when handling compatible acids, caustics, cleaners, water-based fluids, and other process liquids. The 1 inch port size offers a practical combination of flow capacity and compact installation for many plant systems. Depending on the exact model, these pumps may be used in chemical processing, water treatment, finishing, maintenance, and equipment-feed applications. Air operation also allows flow to be adjusted by controlling the air supply. For proper selection, compare the fluid chemistry with the pump body, diaphragm, ball, and seat materials. Also evaluate viscosity, solids content, flow requirement, discharge pressure, suction lift, temperature, and air availability. Browse ARO 1 inch non-metallic pump models to review construction options and technical specifications. When replacing an existing pump, confirm the complete model code and port arrangement to help ensure correct compatibility with the existing system.
