Test results
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 must the supply voltage lie between in order for the SQ/SQE pump to deliver a flow of water?
A: Between 100 V and 250 V
Q: What must the supply voltage lie between in order for the SQ/SQE pump to deliver a flow of water?
A: Between 150 V and 315 V
Q: What must the supply voltage lie between in order for the SQ/SQE pump to deliver a flow of water?
A: Between 230 V and 400 V
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.
