Aro 93111 PTFE Diaphragm

The Aro 93111 is a PTFE replacement diaphragm built for industrial fluid-handling systems. It restores sealing performance in compatible ARO pump assemblies used across chemical-transfer and process-plumbing applications. Maintenance teams and plant engineers specify this part to maintain uptime on existing equipment. Buyers who need a different material or a complete pump assembly will not find it here.

Chemical-resistant PTFE construction

The PTFE material resists aggressive chemicals and elevated temperatures encountered in normal operation. This compatibility reduces diaphragm fatigue and helps maintain consistent flow rates without frequent intervention. No moving mechanical parts or powered components are present, so the part adds no audible noise or electrical draw to the system. Installers should verify the pump model matches the 93111 designation before fitting.
