If you’re spec’ing All-Flo™ PVDF 1/4-inch air diaphragm pumps, here’s what to consider. PVDF is a go-to material when you need a tough thermoplastic wetted path and strong chemical resistance. This smaller inlet size is helpful when you need a compact footprint and straightforward hose-and-fitting compatibility. Here you’ll find All-Flo™ AODD pumps with a PVDF wetted path in the 1/4-inch size, so you can focus on the build that fits your system. Check the available configurations below and choose the build that meets your requirements. Take a minute to confirm media compatibility, operating pressure, temperature limits, and connection style so you end up with the right configuration.
