The Intellidrive is a variable frequency drive for submersible or above-ground well pumps. The water pressure control center directs changes in pump motor speed, responding tofluctuations in demand. If water pressure starts dropping,an electronic pressure transducer signals the drive toaccelerate the pump motor to increase water volume goinginto the home. Traditional well system controls only turn the pump on and off at one speed. The Intellidrive acts as a brain for the system, optimizing water pressure based on needs. In the event that a problem does occur, it will diagnose the issue and disable the pump to prevent further damage. www.pentair.com
