Choosing Wilden® Iron 1-1/2-inch AODD pumps comes down to fit, compatibility, and operating conditions. A 1-1/2-inch inlet is often selected when you want a balance of throughput potential and a reasonable pump footprint. If durability is the priority and weight is less of a concern, iron can be a great fit for tougher-duty use. This combination pairs a Iron wetted path with a 1-1/2-inch connection size, two of the biggest factors when you’re choosing an AODD pump. If you’re replacing an existing unit, double-check your connection size and specs so the swap is smooth. Compare the available models below to find the best fit for your application.
