If you’re spec’ing All-Flo™ Polypropylene 2-inch air diaphragm pumps, here’s what to consider. Polypropylene gives you a corrosion-resistant thermoplastic option that’s widely used for chemical handling. A 2-inch inlet is a smart choice when volume and faster transfer matter more than compact size. Here you’ll find All-Flo™ AODD pumps with a Polypropylene wetted path in the 2-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.
