If you’re spec’ing Wilden® Aluminum 1-inch air diaphragm pumps, here’s what to consider. The 1-inch port size is a great middle ground when you want manageable plumbing without stepping down to the smallest pump frame. Aluminum is a practical choice for everyday industrial service when compatibility checks out. Here you’ll find Wilden® AODD pumps with a Aluminum wetted path in the 1-inch size, so you can focus on the build that fits your system. Take a minute to confirm media compatibility, operating pressure, temperature limits, and connection style so you end up with the right configuration. Check the available configurations below and choose the build that meets your requirements.
