The diaphragm is the one part of an air-operated pump guaranteed to wear out. It flexes millions of times and eventually it goes — which is exactly why you don’t want to be hunting for one when it does. We keep genuine Wilden diaphragms across the range of models and elastomers, ready to ship.
Choosing the material is the whole point. PTFE for the broadest chemical resistance, Santoprene (Wil-Flex) as the tough long-life all-rounder, Buna-N for oils and fuels, Viton for heat and aggressive hydrocarbons, Neoprene for specific duties. Fit the wrong one and it fails early; fit the right one and it runs for years.
Tell us your pump model and what it’s pumping and we’ll confirm the right genuine diaphragm — and, because we stock them, get it on its way fast.
Fits: full Wilden range (flow / head / power not applicable — spare part)
Genuine Wilden AODD Diaphragm Pumps & Spare Parts15-1120-51 is a neoprene valve seat for the Wilden T15 — the surface each check ball lands on. Wear here mimics a bad check ball closely.
Genuine Wilden AODD Diaphragm Pumps & Spare Parts15-1010-51 is the primary neoprene diaphragm for Wilden’s 3″ T15 pumps — the part that actually flexes to move fluid on every stroke.
Genuine Wilden AODD Diaphragm Pumps & Spare Parts15-3520-52 is the Buna-N center block gasket on the Wilden T15. Cheap, easy to overlook, and often blamed on other parts when it leaks.
