Abstract

This project collected corrosion performance data for current metal alloys recommended for pump impellers. This project also quantified the performance of several new and emerging lead-free alloys that are attempting to break into the municipal water market. This data will allow water utilities to make better-informed pump design decisions. The recommendations of this project provide guidance to pump impeller end users and could refine existing alloy manufacturing methods to develop more lasting materials for these applications.
