Variable Speed Pumps

A pump is an electro-mechanical device used to move a substance, usually a liquid or gas, from one location to another. In a variable speed pump, the drive system is varied in order to control the pump flow rate, thereby allowing the pump to run only at the flow rate necessary at any given time. Variable frequency drive systems are typically used to adjust the drive system and therefore control the pump speed. Variable speed pumps improve the overall efficiency of a system and increase the life of the system components, making them a very cost effective upgrade to system with constant speed pumps.
