Ingersoll Rand ARO 93465-G Pneumatic Diaphragm

The 93465-G Geolast diaphragm is a direct replacement part for Ingersoll Rand ARO air-operated diaphragm pumps. In the 93465 family, the -G suffix identifies a Geolast version, a proprietary elastomer used in ARO diaphragms, with Santoprene (93465) as another material option in the same family. Official pump manuals and parts catalogs list 93465-G as the diaphragm component and, in one service listing, show the diaphragm as two units per kit, underscoring its role as a replaceable consumable in maintenance cycles. This diaphragm is designed to seal the pumping chamber and translate pneumatic energy into diaphragm motion in ARO pumps. The product is sold by Ingersoll Rand/ARO and third‑party distributors as a direct replacement part for ARO diaphragm pumps; catalogs and replacement part sheets from sources such as Springer Parts and ARO pump parts listings confirm compatibility with ARO pumps. Availability and compatibility across 93465 variants are documented in supplier literature, including references to Geolast (93465-G) and Santoprene (93465). Typical service uses include routine maintenance and diaphragm replacement to restore pump operation in ARO AODD systems.
