Pump Optimization with Large Impellers Part 1: Why Bigger Really Can Be Better
/
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…?
