Haha. It doesn't have to, I was just trying to give a little background on how pumps work. Really, you just need to check the specs of a pump and match them up with the specs of your spray ball. Most other spray balls besides BH list a flow rate AND a pressure. Higher the pressure you give it, the less flow is needed and vice versa.
