Looking for Anodized Aluminum 3-inch air-operated diaphragm pumps from All-Flo™? This combination pairs a Anodized Aluminum wetted path with a 3-inch connection size, two of the biggest factors when you’re choosing an AODD pump. If you want a metal pump with a tougher finish than standard Aluminum, Anodized Aluminum is worth a look (with compatibility verified). If your system moves more product, the 3-inch format can help with heavier transfer duty and larger piping runs. Before you order, confirm compatibility and operating conditions so the pump you choose performs the way you expect. Compare the available models below to find the best fit for your application.
