Q: Which submersible pump was replaced with a Grundfos SQ?
A: A 4” submersible pump
Q: Which submersible pump was replaced with a Grundfos SQ?
A: A 3” submersible pump
Q: Which submersible pump was replaced with a Grundfos SQ?
A: A 5” submersible pump
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 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: 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 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.
