The frictional head loss (pressure drop) increases with the square of the flow rate. There is a lot more pressure drop (head loss) at 830 than at 560 GPH. There is also a lot more head loss in our piping return systems than we generally believe. Getting more than 800-900 gph from 1" piping is difficult without a pressure rated pump. The published zero head, end of curve, flow ratings that people quote are meaningless unless you plan on using it as a powerhead.
