Difference between axial flow pump and centrifugal pump

Axial flow pump

Centrifugal pump and axial flow pump flow power function curve is not the same, the minimum flow point of the centrifugal pump in the maximum power, axial flow pump minimum flow point power. When the pump starts to take into account the motor's burst, because the minimum power to start.

Therefore, the centrifugal pump start to close the outlet valve, due to the minimum power at the moment, the valve is open, the simple burning motor.

On the contrary, the axial flow pump start to open the outlet valve, due to the minimum power at the moment, the valve closed, then a simple burning motor.
