Shop Wilden® PTFE AODD Pumps
Wilden® 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) uses 100% PTFE for peak chemical resistance; it is stiffer than rubber diaphragms and is often run with a backup diaphragm for extended life. The PSG® Store ships these pumps factory-direct with genuine Wilden parts. Browse the PTFE range below, or filter by body material, port size, and flow rate to match a pump to your media.
