Choosing Wilden® Aluminum 2-inch AODD pumps comes down to fit, compatibility, and operating conditions. This combination pairs a Aluminum wetted path with a 2-inch connection size, two of the biggest factors when you’re choosing an AODD pump. If portability and handling matter, aluminum gives you a lightweight metal option for many general transfer jobs. If your system moves more product, the 2-inch format can help with heavier transfer duty and larger piping runs. For the best long-term fit, compare construction options, diaphragm materials, and system requirements before you select a pump.
