Centrifugal pumps are kinetic devices that continuously impart energy to the fluid passing thru it, nominally designed around a desired flow and head point called the Best Efficiency Point (BEP). Since the BEP is a specific point, it is unlikely to find an application... by Troy Zellers | Nov 12, 2013 | The Pump Experts
Service is a Factor In Part 1, we looked at a simple variable speed (frequency) driven (VFD) motor output chart contrasted with a centrifugal pump duty point. The primary lesson was matching the pump power demand with the motor capability at a given speed. In this... by Troy Zellers | Oct 16, 2013 | The Pump Experts
Driver Constants Growing concerns over energy use and efficiency have fueled more widespread use of variable speed systems to power centrifugal pumps. There are several factors at play, but the design freedom permitted by breaking the bonds to fixed electrical...
