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: Where is domestic groundwater extraction typically relevant?
A: In big cities.
Q: Where is domestic groundwater extraction typically relevant?
A: In remote areas where it is too costly to extend the municipal water supply to just a few houses.
Q: Where is domestic groundwater extraction typically relevant?
A: In smaller and medium sized towns.
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 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
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 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
