Q: Which are the two most common applications in which a Grundfos SQ/SQE submersible pump is used?
A: Groundwater lowering & Irrigation
Q: Which are the two most common applications in which a Grundfos SQ/SQE submersible pump is used?
A: Domestic water supply & Groundwater lowering
Q: Which are the two most common applications in which a Grundfos SQ/SQE submersible pump is used?
A: Domestic water supply & Irrigation
Q: What happens if the static water level is too low?
A: The pump overheats
Q: What happens if the static water level is too low?
A: The water level is brought down below the inlet of the pump
Q: What happens if the static water level is too low?
A: The motor shuts down
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.
