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…

Let’s take a closer look at the benefits of specifying a pump with an optimized impeller. As a reminder, an optimized impeller is the largest impeller that won’t….

A retired engineer I know once said, "There is no glory in an undersized….”

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…?

Last month, the U.S. Department of Energy (DOE) announced findings from a study that offers robust confirmation that mass deployment of geothermal heat pumps….
