How does the integrated dry-running protection work?
What happens if the water level in the well drops below the inlet?
By how much does the supply voltage decrease before the motor contactor stops the pump?
In addition to limiting the current draw from the mains during start-up of the pump, how does the soft-start functionality benefit operation?
Why must the pump unit be installed below the dynamic water table?
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: 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: Is the SQE pump able to provide constant pressure?
A: No.
Q: Is the SQE pump able to provide constant pressure?
A: Yes.
Q: By how much does the supply voltage decrease before the motor contactor stops the pump?
A: More than 10 %
Q: By how much does the supply voltage decrease before the motor contactor stops the pump?
A: More than 15 %
Q: By how much does the supply voltage decrease before the motor contactor stops the pump?
A: More than 20 %
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.
Q: Why must the pump unit be installed below the dynamic water table?
A: So you are sure to minimise your power bill.
Q: Why must the pump unit be installed below the dynamic water table?
A: To avoid the risk of dry-running during operation.
Q: Why must the pump unit be installed below the dynamic water table?
A: To maintain a stable pressure in the system.
