ABSTRACT:
A variable speed pumping system and an associated method for moving water of an aquatic application. The variable speed pumping system includes a water pump for moving water in connection with performance of an operation upon the water. A variable speed motor is operatively connected to drive the pump. A sensor senses a parameter of the operation performed upon the water. A controller controls speed of the motor in response to the sensed parameter of operation.
