If you’re spec’ing Wilden® PVDF 1-1/2-inch air diaphragm pumps, here’s what to consider. The 1-1/2-inch format makes sense when you need a step up in capability without jumping to the largest pump sizes. PVDF is a go-to material when you need a tough thermoplastic wetted path and strong chemical resistance. Here you’ll find Wilden® AODD pumps with a PVDF wetted path in the 1-1/2-inch size, so you can focus on the build that fits your system. Take a minute to confirm media compatibility, operating pressure, temperature limits, and connection style so you end up with the right configuration. Check the available configurations below and choose the build that meets your requirements.
