Replacing a Sicce 12.0 with a (much) smaller Sicce pump

[jgvergo]

I need to replace a Sicce 12.0 pump. I am running a bean animal set up with 1" PVC. My old set up had my sump one floor below my DT, 3 90 degree elbows in the PVC and 10' of head height. The new set up has the sump is directly below the DT (approximately 4' of head height and no 90 degree elbows).

I'd like to stay with Sicce because they have provided excellent customer support over the years. So my question is which Sicce pump is sufficient for my current set up?

Thanks in advance!

One of the SDC models. Maybe SDC 6.0 or 7.0?
