Shop All-Flo™ PTFE AODD Pumps
All-Flo™ AODD pumps with PTFE diaphragms offer the broadest chemical resistance available, handling aggressive acids, solvents, and high-purity or sanitary fluids that defeat other elastomers. PTFE (often known by the Teflon trade name) is the go-to when chemical compatibility leads the spec; it is stiffer than rubber diaphragms and is frequently run with a backup diaphragm for longer life. The PSG® Store ships these pumps factory-direct with genuine All-Flo parts. Browse the PTFE range below, or filter by body material, port size, and flow rate to match a pump to your media.
