Correct
Q: Is the SQE pump able to provide constant pressure?
A: Yes.
Correct
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
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
Q: How does the integrated dry-running protection work?
A: It automatically shuts down the pump if water shortage is detected.
Correct
Q: What is the benefit of a slow increase in speed?
A: It keeps the motor current low
Correct
Q: How many times higher than nominal speed does the motor current reach during the first milliseconds?
A: Seven times higher
Correct
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
Q: What happens if the water level in the well drops below the inlet?
A: The motor power consumption stays the same
Correct
Q: What is a key installer benefit of the voltage protection in SQ/SQE?
A: Fewer service visits
Correct
Q: Which protection features does the SQE have?
A: Voltage handling, soft start, dry-running protection and overload protection.
