Shop Wilden® Polyurethane AODD Pumps
Wilden® AODD pumps with polyurethane diaphragms are built for abrasion, making them an excellent fit for slurries, gritty media, and punishing applications that wear out standard elastomers. Polyurethane is a thermoplastic-elastomer diaphragm whose toughness extends life where abrasion is the limiting factor, though it is not suited to many chemicals or hot fluids — confirm compatibility with your media. The PSG® Store ships these pumps factory-direct with genuine Wilden parts. Browse the polyurethane range below, or filter by body material, port size, and flow rate to match a pump to your abrasive duty.
