Correct
01.
Q: How long did it take to replace the pump with a Grundfos SQ?
A: 60 minutes
Correct
02.
Q: Which protection features does the SQE have?
A: Voltage handling, soft start, dry-running protection and overload protection.
Correct
03.
Q: Where is domestic groundwater extraction typically relevant?
A: In remote areas where it is too costly to extend the municipal water supply to just a few houses.
Correct
04.
Q: What is the benefit of a slow increase in speed?
A: It keeps the motor current low
Correct
05.
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
06.
Q: What happens if the water level in the well drops below the inlet?
A: The motor power consumption stays the same
Correct
07.
Q: By how much does the supply voltage decrease before the motor contactor stops the pump?
A: More than 10 %
Correct
08.
Q: Which are the two most common applications in which a Grundfos SQ/SQE submersible pump is used?
A: Domestic water supply & Irrigation
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: 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.
