Pressure and Ratio Ratings for President Pumps

WARNING

To reduce the risk of over pressurizing a component, which can result in an explosion and serious injury, never

operate the system at a working pressure higher than the lowest rated component in the system. All fluid side

components such as dispensing valves, regulators, and hoses must have a working pressure equal to or greater

than the pressure given in Column B for each pump model.

Column A gives the maximum fluid pressure developed at 100 psi (0.7 MPa, 7 bar) of incoming air pressure.

Column B gives the minimum working pressure required for all system components, based on the automatic

relief valve settings. Components included by Graco with the models listed meet or exceed this requirement.
