666100-144-C ARO 1" Aluminum Metallic Pro Series Air Operated Double Diaphragm Pump
AROP/N 666100-144-C ARO 1" Aluminum Metallic Pro Series Air Operated Double Diaphragm Pump
The ARO 666100-144-C is a metallic Pro Series 1-inch air-operated double-diaphragm pump designed for dependable fluid transfer in industrial and process applications. Its aluminum construction, combined with PTFE diaphragms with Santoprene® backup, PTFE check balls, and aluminum seats, provides a durable fluid-handling configuration for a variety of applications.
The single-manifold design provides a compact configuration, while ARO describes the bolted construction as supporting “leak-free fluid handling.” Accessible ball checks and fluid caps also help simplify routine service and maintenance. Its 1-inch design supports common transfer, circulation, filling, and batching duties across industrial, chemical, petrochemical, construction, and other process environments.
Application suitability should be confirmed based on the specific fluid, concentration, temperature, chemical compatibility, solids content, and operating conditions.
