Typical Installation
About Typical Installations
The typical installations shown below and on pages 8
and 9 are only guidelines to setting up a complete
proportioning system. For clarity, various components
are shown in the correct order but may not be shown in
the exact position of the installed system. For assis-
tance in designing your system, contact your nearest
Graco representative.
NOTE:
When pressure feeding the proportioning
pump, mount fluid pressure gauges (J) at the propor-
tioning pump inlets to monitor proper adjustment of the
feed pump pressures.
Never exceed 400 psi on the
inbound fluid pressure and never exceed 25% of
the Hydra-Cat pump outbound fluid pressure on
the feed supply.
