3: 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.
4: 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.

4: 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.
4: 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.

5: Is the SQE pump able to provide constant pressure?
Yes.
6: What is the benefit of a slow increase in speed?
It keeps the motor current low
6: What is the benefit of a slow increase in speed?
It keeps pump movements at a minimum
