3: Is the SQE pump able to provide constant pressure?
Yes.
4: 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.
4: Why is it important to protect the pump from over- and under voltage?
To avoid burning the house fuses.
