Q: How long did it take to replace the pump with a Grundfos SQ?
A: 30 minutes
Q: How long did it take to replace the pump with a Grundfos SQ?
A: 60 minutes
Q: How long did it take to replace the pump with a Grundfos SQ?
A: 90 minutes
Q: Why is correct sizing of the submersible pump important?
A: 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.
Q: Why is correct sizing of the submersible pump important?
A: Because too small a pump will pump the well dry.
Q: Why is correct sizing of the submersible pump important?
A: Because too big a pump will ruin the taps due to too high pressure.

Q: Is the SQE pump able to provide constant pressure?
A: No.
Q: Is the SQE pump able to provide constant pressure?
A: Yes.
Q: Which protection features does the SQE have?
A: Voltage handling, soft start, dry-running protection and overload protection.
Q: Which protection features does the SQE have?
A: Protection against the well running dry.
Q: Which protection features does the SQE have?
A: The SQE does not have any protection features.
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.
