This generation of variable-speed pumps can internally sense how many valves are open or closed and adjust speed accordingly. Variable speed pumps have been around for years. As I mentioned in last ...

As the cost of components and pumps becomes more affordable, variable speed pumps are being used to increase the efficiency and reliability of water distribution systems in multi-story buildings.

LONG BEACH, Calif. - Pumps are responsible for a significant part of the world’s electrical energy consumption, but their impact can be by using variable-speed pump control, especially in hydronic ...

Can variable speed pumps be used on compensated heating circuits, in place of three port and pressure relief valves. Are they cost effective, and how is the pump controlled? Variable speed driven ...

Chris Parsloe argues that a modular approach to system design helps exploit the energy saving potential of variable speed pumps In the shadows cast by Part L of the new Building Regulations and the ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...
