ARO 94091-A Diaphragm Assembly

The ARO 94091-A diaphragm is a precision-molded elastomeric component designed for use in ARO 6000 and 4200 series air-operated double diaphragm (AODD) pumps. Constructed from Santoprene thermoplastic rubber, it offers broad chemical resistance and superior flex fatigue performance compared to standard rubber compounds. This diaphragm serves as the primary dynamic sealing element separating the compressed air drive side from the fluid path. Compatible pump models include the 6CCP5, 6CCR7, 6CCT0, and 42CG82 series. The part features a cream color designation for material identification. It replaces OEM part number 94091-A directly. Installation requires standard pump disassembly procedures. The component is non-returnable per industrial supplier policy.
