1/2" METALLIC | ARO Pumps & Parts

ARO 1/2 inch metallic diaphragm pumps provide a compact air-operated solution for industrial fluid transfer where durable metallic construction is preferred. Their size makes them useful for equipment feed, drum transfer, circulation, dispensing, maintenance, and other applications that require moderate flow in a relatively small installation space. Depending on the specific material configuration, metallic diaphragm pumps can be used with oils, coatings, solvents, water-based fluids, chemicals, and other compatible process liquids. Multiple diaphragm and valve material options may be available to match different chemical, temperature, and wear requirements. Choosing the correct 1/2 inch metallic pump requires reviewing flow rate, discharge pressure, suction conditions, viscosity, solids content, temperature, and chemical compatibility. Body material and elastomer selection should be matched carefully to the fluid. Also consider air pressure and air quality to support consistent operation. Browse the available ARO 1/2 inch metallic diaphragm pump models to compare specifications and select the configuration that best fits your application. Verify the complete model number before ordering replacements or service parts.
