What type of pump would be most appropriate for pumping lake or pond water from one side of a barrier, through the barrier, to other side? There is to be no change in elevation and the barrier is fabric (and thus there is little friction as the distance to be pumped is very short). Temperatures will range from 60 to 90f and energy efficiency is very important. Flow rates are 1500 to 2000 gph. Would like to do better in efficiency than DC bilge pumps which generate unnecessary pressure.
