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: 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 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: The 3” SQ pump is obviously ideal for new boreholes but where can it also be used?
A: In wells with water temperature up to 60° C.
Q: The 3” SQ pump is obviously ideal for new boreholes but where can it also be used?
A: In installations that require constant pressure.
Q: The 3” SQ pump is obviously ideal for new boreholes but where can it also be used?
A: In original 4” boreholes where sediments over the years have narrowed the hole.
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 most commonly used starting method for motors in 4” conventional pumps?
A: Direct on line
Q: What is the most commonly used starting method for motors in 4” conventional pumps?
A: Star delta starters
Q: What is the most commonly used starting method for motors in 4” conventional pumps?
A: Auto transformer
