1: Is the SQE pump able to provide constant pressure?
Yes.
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.

3: In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
Soft start reduces over-pressure in your piping.

3: In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
It reduces the occurrence of water hammer in the pipes and minimises wear during start-up.
3: In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
Soft start prevents the motor from getting warm.

4: What is the benefit of a slow increase in speed?
It keeps the motor current low
4: What is the benefit of a slow increase in speed?
It keeps pump movements at a minimum

5: 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.
6: Which protection features does the SQE have?
Voltage handling, soft start, dry-running protection and overload protection.
