The Grundfos variable speed pump uses a variable frequency drive integrated into the pump to pump water efficiently. The integrated drive can be used to maintain a pre-programmed pressure set point and will vary the pump speed to maintain that pressure set point. The red valve handle on the side can be turned to change the resistance of the valve and will allow the pump to change its speed. The readout on the top of the display shows the flow rate of the water in the system.
