Our last series taught us that pumps with untrimmed impellers and variable frequency drives (i.e., optimized impeller pumps) can often exceed design head and flows without penalty. Now, we're really going to blow your mind. Did you know…

Variable speed drives (VSDs) are less expensive and more reliable than a decade ago, paving the way for new best practices when specifying pumps. Traditionally, pumps have been specified with impellers trimmed to deliver peak load without overloading the pump motor. But is all that trimming necessary…?
