How would you rate this course?
1: Why is correct sizing of the submersible pump important?
Because an undersized pump will not be able to deliver the required flow and pressure and an oversized pump reduces energy efficiency, which increases operational costs.
1: Why is correct sizing of the submersible pump important?
Because too small a pump will pump the well dry.

2: Where is domestic groundwater extraction typically relevant?
In remote areas where it is too costly to extend the municipal water supply to just a few houses.
2: Where is domestic groundwater extraction typically relevant?
In smaller and medium sized towns.

3: What happens if the static water level is too low?
The pump overheats
You can find the answer here >
3: What happens if the static water level is too low?
The water level is brought down below the inlet of the pump
3: What happens if the static water level is too low?
The motor shuts down

4: What happens if the water level in the well drops below the inlet?
The motor power consumption drops
4: What happens if the water level in the well drops below the inlet?
The motor power consumption stays the same

5: What is a key installer benefit of the voltage protection in SQ/SQE?
Fewer service visits
6: Why is it important to protect the pump from over- and under voltage?
Because large variations in power supply will damage the motor over time.
6: Why is it important to protect the pump from over- and under voltage?
To avoid burning the house fuses.
