Q: What must the supply voltage lie between in order for the SQ/SQE pump to deliver a flow of water?
A: Between 230 V and 400 V
Q: Which of these isn’t a key dry-run protection benefit for the installer?
A: The installer can avoid costly callbacks
Q: Which of these isn’t a key dry-run protection benefit for the installer?
A: The installer doesn’t have to worry about additional components
Q: Which of these isn’t a key dry-run protection benefit for the installer?
A: The installer doesn’t have to worry about water bursts
Q: Which are the two most common applications in which a Grundfos SQ/SQE submersible pump is used?
A: Groundwater lowering & Irrigation
Q: Which are the two most common applications in which a Grundfos SQ/SQE submersible pump is used?
A: Domestic water supply & Groundwater lowering
Q: Which are the two most common applications in which a Grundfos SQ/SQE submersible pump is used?
A: Domestic water supply & Irrigation
Q: What happens if the water level in the well drops below the inlet?
A: The motor power consumption drops
Q: What happens if the water level in the well drops below the inlet?
A: The motor power consumption stays the same
Q: What happens if the water level in the well drops below the inlet?
A: The motor power consumption increases
Q: Why is it important to protect the pump from over- and under voltage?
A: Because large variations in power supply will damage the motor over time.
Q: Why is it important to protect the pump from over- and under voltage?
A: To avoid burning the house fuses.
Q: Why is it important to protect the pump from over- and under voltage?
A: To minimise the power consumption.
