ARO 94329-A Diaphragm by Ingersoll Rand

The ARO 94329-A is a genuine replacement diaphragm designed for compatible ARO air-operated double diaphragm pump assemblies. Constructed from Santoprene, the 94329-A serves as a primary fluid-section diaphragm in compatible ARO pump configurations. During pump operation, the diaphragm flexes to create the alternating suction and discharge action required for reliable fluid transfer. Santoprene provides a durable elastomer construction suited for many compatible industrial fluid-handling applications. Correct diaphragm material selection is important and should always be based on the chemical, temperature, and operating conditions of the pumped fluid. The ARO 94329-A is suitable for preventive maintenance, fluid-section rebuilding, and replacement of worn, fatigued, cracked, or damaged diaphragms. Installing the correct genuine replacement diaphragm helps maintain proper sealing, displacement, and dependable pump performance. This part is used in compatible ARO diaphragm pump configurations that specify part number 94329-A. Always verify the exact ARO pump model, parts list, fluid compatibility, and diaphragm material requirements before installation.
