Abstract
A pump control system and a controller therefor are disclosed which operate a motorized pump in a controlled fashion. The controller provides a control signal to a motor drive according to a setpoint or according to a cavitation signal from a cavitation detection component in the controller. If the cavitation detection component determines that pump cavitation is likely or suspected, the controller may operate the pump motor according to the cavitation signal, in order to reduce or eliminate the cavitation condition, before resuming normal control according to the setpoint.
