Shop All-Flo™ EPDM AODD Pumps
All-Flo™ AODD pumps with EPDM diaphragms are well-suited to water, wastewater, dilute acids and bases, ketones, and many hot-water applications. EPDM resists a broad range of water-based chemistries and elevated temperatures, but it is not compatible with petroleum oils, fuels, or most hydrocarbons — confirm your media before specifying. The PSG® Store ships these pumps factory-direct with genuine All-Flo parts. Browse the EPDM range below, or filter by body material, port size, and flow rate to find the right pump for your application.
