quiet one 6000 vs 4000HH

[Dragon Hunter]

Which is a better pump for my sump i want as much water flow as possible.

Not to be obtuse, but details? The 4000HH has a higher head height (something like 13' compared to the 6000 with 12'ish). The 6000 has a higher flow rate at 0' head height (1500 or so compared to 900 or so). At some point along the graph, the 4000HH overtakes the 6000. So, the question becomes "How high will your pump have to push water out of your sump to your tank?"

Go with the 6000 then.
