A method and apparatus are provided for controlling the operation of a pump in a pumping system, featuring sensing a no water or dead head condition of the flow of a medium in the pumping system operating at a set point pressure; and dynamically reducing the set-point pressure to a lower set point pressure that allows for the flow of the medium to continue at the lower set point pressure while further monitoring the flow of the medium through the pump to protect the pump against damage due to the no water or dead head condition.
