If you’re spec’ing Wilden® PVDF 1-inch air diaphragm pumps, here’s what to consider. Here you’ll find Wilden® AODD pumps with a PVDF wetted path in the 1-inch size, so you can focus on the build that fits your system. PVDF is a go-to material when you need a tough thermoplastic wetted path and strong chemical resistance. The 1-inch port size is a great middle ground when you want manageable plumbing without stepping down to the smallest pump frame. If you’re replacing an existing unit, double-check your connection size and specs so the swap is smooth. Check the available configurations below and choose the build that meets your requirements.
