3: Why is it important to protect the pump from over- and under voltage?
Because large variations in power supply will damage the motor over time.
3: Why is it important to protect the pump from over- and under voltage?
To avoid burning the house fuses.

4: What happens if the water level in the well drops below the inlet?
The motor power consumption drops
4: What happens if the water level in the well drops below the inlet?
The motor power consumption stays the same
You can find the answer here >
4: What happens if the water level in the well drops below the inlet?
The motor power consumption increases
You can find the answer here >
5: What is the benefit of a slow increase in speed?
It keeps the motor current low
5: What is the benefit of a slow increase in speed?
It keeps pump movements at a minimum
