What is the benefit of a slow increase in speed?
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 it important to protect the pump from over- and under voltage?
A: Because large variations in power supply will damage the motor over time.
Q: Why is it important to protect the pump from over- and under voltage?
A: To avoid burning the house fuses.
Q: Why is it important to protect the pump from over- and under voltage?
A: To minimise the power consumption.
Q: What happens if the static water level is too low?
A: The pump overheats
Q: What happens if the static water level is too low?
A: The water level is brought down below the inlet of the pump
Q: What happens if the static water level is too low?
A: The motor shuts down
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: 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: What is the benefit of a slow increase in speed?
A: It keeps the motor current low
Q: What is the benefit of a slow increase in speed?
A: It keeps pump movements at a minimum
Q: What is the benefit of a slow increase in speed?
A: It removes the need for motor contactors
