1: 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.
2: Which protection features does the SQE have?
Voltage handling, soft start, dry-running protection and overload protection.
2: Which protection features does the SQE have?
Protection against the well running dry.
You can find the answer here >
2: Which protection features does the SQE have?
The SQE does not have any protection features.

3: 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.
3: Why is correct sizing of the submersible pump important?
Because too small a pump will pump the well dry.

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

4: How does the integrated dry-running protection work?
It prevents sand from damaging the pump.

4: How does the integrated dry-running protection work?
It automatically shuts down the pump if water shortage is detected.
5: 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.

5: 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.
5: 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.
