Looking for Polypropylene 1-inch air-operated diaphragm pumps from All-Flo™? This combination pairs a Polypropylene wetted path with a 1-inch connection size, two of the biggest factors when you’re choosing an AODD pump. If you prefer a non-metallic wetted path, Polypropylene is a versatile option to consider for compatibility-driven specs. This inlet size gives you a practical balance between compact installation and the line size many plants already use. As you narrow your choice, match the wetted material to your fluid chemistry and verify pressure, temperature, and installation requirements. Compare the available models below to find the best fit for your application.
