Pump for 7.5ft lift ATO

[Chasman]

The base of my 40 gal water containers are 7.5 feet below the top edge of the sump. Water containers are in the basement. There are some very good ATO and AWC systems out there, but give no advice on head pressure requirements and so on. What I have found that by the numbers would work is the Sicce 3.0 pump in the containers. Seems a bit much, but the little pumps associated with the ATO/AWC kits are quite small. Good for level water transfer.

Any thoughts or experience would help.
