3: How many times higher than nominal speed does the motor current reach during the first milliseconds?
3: How many times higher than nominal speed does the motor current reach during the first milliseconds?
Seven times higher
4: Is the SQE pump able to provide constant pressure?
4: Is the SQE pump able to provide constant pressure?
Yes.
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.

6: Why must the pump unit be installed below the dynamic water table?
To avoid the risk of dry-running during operation.
6: Why must the pump unit be installed below the dynamic water table?
To maintain a stable pressure in the system.
