900 gpm recirculating river

[J Strong]

Hello,
I am creating a recirculating river system. The ideal flow calculation has been set at just under 900 gpm / 54,000 gph. I am looking for a pump or pumps that can move that water in the most cost effective way.
Please advise me of your recommendation for the most overall efficient type of water pump to move 900+ gpm.
I will be pumping pool water approx. 1000' away. The rise is approx. 6' over that distance.

Thank you,
J Strong

I am guessing at 20' total head, figuring friction losses. The first pump I came up with is a Berkeley B5WPS in 7.5HP. You should be able to get a 7.5 HP motor in either single phase or three phase if three phase is available.
