Using a pressure tank or pressure system? You'll need to add the depth of your well with the PSI in feet of head to get your "Total Head" number for sizing. 

10 PSI = 23 feet of head 

20 PSI = 46 feet of head 

30 PSI = 70 feet of head 

40 PSI = 90 feet of head 

50 PSI = 115 feet of head 

60 PSI = 140 feet of head

Example: 50 foot (well depth) + 90 feet of head (from a 40 PSI pressure tank) = 140 feet of total head. If your total head number exceeds this pumps ability range, size up to get a similar flow with higher head ability!
