    If you go back to may previous post #6 you will see 3 to 5x the display volume after head loss. That may very well be 10x the display volume for the maximum the pump can do but you need to calculate the head losses so you know what it will be at the display or discharge point. Thats the final number. Add up the total feet of head then find a pump that will do about 5x the display volume at that head loss.
