Test results
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: 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: 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.
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: 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: 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.
