Test results
Q: How does the integrated dry-running protection work?
A: It automatically restarts 3 minutes after shut down.
Q: How does the integrated dry-running protection work?
A: It prevents sand from damaging the pump.
Q: How does the integrated dry-running protection work?
A: It automatically shuts down the pump if water shortage is detected.
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: What is a key installer benefit of the voltage protection in SQ/SQE?
A: Steady water supply
Q: What is a key installer benefit of the voltage protection in SQ/SQE?
A: Faster installation
Q: What is a key installer benefit of the voltage protection in SQ/SQE?
A: Fewer service visits
Q: What happens if the water level in the well drops below the inlet?
A: The motor power consumption drops
Q: What happens if the water level in the well drops below the inlet?
A: The motor power consumption stays the same
Q: What happens if the water level in the well drops below the inlet?
A: The motor power consumption increases
Q: How many times higher than nominal speed does the motor current reach during the first milliseconds?
A: Four times higher
Q: How many times higher than nominal speed does the motor current reach during the first milliseconds?
A: Six times higher
Q: How many times higher than nominal speed does the motor current reach during the first milliseconds?
A: Seven times higher
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
