What is a key installer benefit of the voltage protection in SQ/SQE?
Which submersible pump was replaced with a Grundfos SQ?
How long did it take to replace the pump with a Grundfos SQ?
How many times higher than nominal speed does the motor current reach during the first milliseconds?
In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
Why must the pump unit be installed below the dynamic water table?

Q: In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
A: Soft start reduces over-pressure in your piping.
Q: In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
A: It reduces the occurrence of water hammer in the pipes and minimises wear during start-up.
Q: In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
A: Soft start prevents the motor from getting warm.
Q: Why must the pump unit be installed below the dynamic water table?
A: So you are sure to minimise your power bill.
Q: Why must the pump unit be installed below the dynamic water table?
A: To avoid the risk of dry-running during operation.
Q: Why must the pump unit be installed below the dynamic water table?
A: To maintain a stable pressure in the system.
