Flow, Head & Sizing Considerations for ECM Circulators

Presented by John Barba, Dave Holdorf and Rick Mayo

The term “Smart Pump” has, unfortunately, led to considerable confusion over just what residential ECM circulators can and cannot do. Despite variable speed capabilities, you still need to determine flow and head requirements of your system in order to select the right operating mode for each job.

In this fast-paced, fact-filled hour, we’ll discuss the right way to determine both flow and head loss in a system. We’ll also help you understand the importance of system curves and pump performance curves, and how that understanding can help you optimize your variable speed circulators to get the maximum benefits these amazing little devices provide.
