How would you rate this course?
1: What is the benefit of a slow increase in speed?
It keeps the motor current low
1: What is the benefit of a slow increase in speed?
It keeps pump movements at a minimum

1: What is the benefit of a slow increase in speed?
It removes the need for motor contactors

2: 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.
2: Why is correct sizing of the submersible pump important?
Because too small a pump will pump the well dry.

2: Why is correct sizing of the submersible pump important?
Because too big a pump will ruin the taps due to too high pressure.

4: The 3” SQ pump is obviously ideal for new boreholes but where can it also be used?
In original 4” boreholes where sediments over the years have narrowed the hole.
