Usage
The XPs-hf proportioner is a plural component sprayer
that can mix and spray most two component epoxy and
urethane protective coatings. It is a fixed-ratio system,
where XP lowers can be changed to reconfigure the
system to different volume mix ratios or spray
pressures. See details on page 15.
All models are mounted on a metal skid, and are
equipped with heated hoppers where the resin (A
material) and catalyst (B material) are heated and
pressure fed to the XP-hf pump assembly.
The materials are pumped to the primary heaters, where
the resin and hardener are heated to the required spray
temperatures. Heat improves the chemical reaction and
lowers viscosity to improve the spray pattern.
The materials then flow to the mix manifold assembly.
The mix manifold assembly consists of a recirculation
manifold, mix manifold, and solvent flush valve. At the
recirculation manifold, the materials either recirculate
back to the heated hopper for continued heating, or
combine at the mix manifold into one fluid line. The
mixed material then flows through static mixers for
continued mixing to the whip hose and out the spray
gun.
The solvent flush system flushes the mixed material out
of the manifold, static mixers, mixed material hoses, and
spray gun.
When using quick-setting materials (less than 10 minute
pot life) a remote mix manifold must be used. The mix
manifold is separated from the recirculation manifold
and mounted on a remote carriage. Heated hoses are
used to prevent temperature loss in the materials while
flowing to the remotely mounted mix manifold. Systems
are configured to connect either a water heated hose, or
an electric heated hose. Heated hoses are sold
separately in various configurations and lengths
depending on customer need.
Over Pressure Protection
Mechanically linked pumps can create excessive fluid
pressure if the full motor force is applied to only one of
the fluid pumps.
To reduce the risk of injury due to skin injections,
perform the following:
• A maximum air pressure set point blow-off valve is
provided to limit maximum fluid pressure. Do not
remove these valves.
• Color-coded, automatic, over-pressure relief valves
are used to transfer excess fluid pressure back to
the supply. Never plug the return hoses. See Fluid
Control Assembly, on page 18.
• Never install individual shut off valves on the “A”
and “B” lines. Common handles link the fluid control
valves.
• A rupture disk is provided on the “B” material pump
(pumps 145 cc and smaller) as a back-up to the
over-pressure relief valve. If the rupture disk ever
opens, do not operate the machine until the
over-pressure valve and the rupture disc have been
replaced.
• If changing pump lowers on your system, use the
correct over-pressure relief valves from the chart on
page 58.
