The pump is contolled via a digital low-voltage pulse-width modulation signal which means that the
speed of rotation depends on the input signal.The speed changes as a function of the input profile.
The relationships between the head and the water flow rated,the PMW Return and the water flow
rated are shown in the graph below.
