Hello, I am trying to size a pump system but this results to a negative discharge. I am trying to pump a water at 25 C to 50ft above grade. This results to a negative differential head. The path is that it must go up the piperack of 50ft then passes through it then goes back to grade level for some reason. Can you please help me what missing concepts I am here? Please see the result of the sizing using a software below (see attached file)

try to reduce head losses, let say increase pipe diameter and or change the pump with higher TDH.
Note:PIPE SUCTION LINE SHOULD BE BIGGER OR EQUAL TO PIPE DISCHARGE LINE.
my 2 cents
