If you’re spec’ing™ All-Flo PVDF 1-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. The 1-inch port size is a great middle ground when you want manageable plumbing without stepping down to the smallest pump frame. Here you’ll find All-Flo™ AODD pumps with a PVDF wetted path in the 1-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. If you’re replacing an existing unit, double-check your connection size and specs so the swap is smooth.
