1" NON-METALLIC 6661A | ARO Pumps & Parts | Page 3

ARO 1 inch 6661A non-metallic diaphragm pumps are designed for a broad range of industrial fluid-transfer duties where air-operated performance and non-metallic wetted construction are beneficial. These pumps can support chemical transfer, equipment feed, recirculation, tank unloading, and general process applications with compatible fluids. The 1 inch port size offers useful flow capability for many production and maintenance systems while remaining practical for installations with limited space. Non-metallic construction can be particularly useful when selected chemicals may be unsuitable for certain metals, but the exact material combination must always be matched to the fluid. When choosing a 6661A pump, consider body material, diaphragm material, ball and seat materials, flow demand, operating pressure, fluid viscosity, solids content, temperature, and suction conditions. Air supply pressure and quality should also be reviewed. Browse the available ARO 6661A non-metallic pump configurations to compare technical details. For replacements, use the complete existing model number and material code to identify the correct pump configuration or service components.
