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: 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 is the most commonly used starting method for motors in 4” conventional pumps?
A: Auto transformer
Q: Which of these isn’t a key dry-run protection benefit for the installer?
A: The installer can avoid costly callbacks
Q: Which of these isn’t a key dry-run protection benefit for the installer?
A: The installer doesn’t have to worry about additional components
Q: Which of these isn’t a key dry-run protection benefit for the installer?
A: The installer doesn’t have to worry about water bursts
Q: What is a key installer benefit of the voltage protection in SQ/SQE?
A: Steady water supply
Q: What is a key installer benefit of the voltage protection in SQ/SQE?
A: Faster installation
Q: What is a key installer benefit of the voltage protection in SQ/SQE?
A: Fewer service visits
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.
