    With recirculation - When demand is satisfied and the motor speed is reduced to its minimum, and some recirculation of feedwater to the feedtank is still required to avoid the pump overheating (see Figure 3.17.5). Without recirculation - In this case the motor controller stops the feedpump at very low boiler loads, so recirculation is not required.Learn More
