Pressure and Ratio Ratings for Bulldog Pumps
WARNING
COMPONENT RUPTURE HAZARD
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 pump fluid output 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.
