1psi = 2ft of lift, that is 1 bar = 14.7psi = 30ft lift so roughly 2ft per psi.
therefore a 100psi pump will pump to 200ft but that is only the pressure switch setting, it will pump as high as the internal setting in the varistream is set, I think max on the varistream is roughly 130psi with the 8000 series shurflo pumps. Basically its an awful lot higher than you can pole to.
