Correct
04.
Q: Which are the two most common applications in which a Grundfos SQ/SQE submersible pump is used?
A: Domestic water supply & Irrigation
Correct
05.
Q: In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
A: It reduces the occurrence of water hammer in the pipes and minimises wear during start-up.
Correct
06.
Q: The 3” SQ pump is obviously ideal for new boreholes but where can it also be used?
A: In original 4” boreholes where sediments over the years have narrowed the hole.
Correct
07.
Q: What must the supply voltage lie between in order for the SQ/SQE pump to deliver a flow of water?
A: Between 150 V and 315 V
Correct
08.
Q: What happens if the water level in the well drops below the inlet?
A: The motor power consumption stays the same
Correct
09.
Q: How does the integrated dry-running protection work?
A: It automatically shuts down the pump if water shortage is detected.
Correct
10.
Q: Which of these isn’t a key dry-run protection benefit for the installer?
A: He doesn’t have to worry about water bursts
