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: How does the integrated dry-running protection work?
A: It automatically restarts 3 minutes after shut down.
Q: How does the integrated dry-running protection work?
A: It prevents sand from damaging the pump.
Q: How does the integrated dry-running protection work?
A: It automatically shuts down the pump if water shortage is detected.
