ARO 666101-462-C Diaphragm Pump

The ARO 666101-462-C is a 1-inch metallic Pro Series air-operated double-diaphragm (AODD) pump designed for high-volume fluid transfer in demanding industrial environments, delivering rugged metal construction and dependable performance across chemicals, coatings, inks, and cleaning fluids. As part of the Pro Series Metallic line, this variant is specified for a maximum operating pressure of 120 psi (8.3 bar), with stainless steel center-body configurations in the 666101 family that emphasize corrosion resistance for aggressive liquids such as solvents and caustics. ARO’s Pro Series diaphragms employ an unbalanced air valve to provide no-stall operation, helping maintain continuous flow when suction is flooded or inlet conditions vary and supporting smoother startup and stable throughput. The 1-inch size denotes standard field compatibility within the family, and diaphragm and fluid-cap materials are configurable to suit different fluids and temperatures, ensuring you can tailor the pump to your chemical compatibility and service requirements.
