  FLOW DATA FOR DELIVERY HEADS BASED ON FALL

The chart indicates lift in feet relative to the fall / drive and the flow rate available.  The numbers at the top of each chart indicate the fall and drive pipe length (2-10 means 2 feet of fall with a 10 foot long drive pipe).  For example, to obtain a flow of 500 gallons per day at a lift of 67.2 feet, the proper installion would require 9 feet of fall and 45 feet of drive pipe.
