Typical Installation
About the Typical Installations
These pumps are designed to be part of a Hydra-Cat
dispensing system that will proportion, mix, and
dispense two-component fluids. The typical installa-
tions shown below and on page 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 exactly the position of
the installed system. For assistance in designing your
system, contact your Graco distributor.
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 25% of the
Hydra-Cat pump outbound fluid pressure on the feed
supply.
