Correct
01.
Q: What happens if the static water level is too low?
A: The water level is brought down below the inlet of the pump
Correct
02.
Q: Is the SQE pump able to provide constant pressure?
A: Yes.
Correct
03.
Q: How many times higher than nominal speed does the motor current reach during the first milliseconds?
A: Seven times higher
Correct
04.
Q: What is the benefit of a slow increase in speed?
A: It keeps the motor current low
Correct
05.
Q: Why must the pump unit be installed below the dynamic water table?
A: To avoid the risk of dry-running during operation.
Correct
06.
Q: Which are the two most common applications in which a Grundfos SQ/SQE submersible pump is used?
A: Domestic water supply & Irrigation
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
