Overview
Usage
The XP is a mechanically linked fixed ratio system that
can mix and spray most two-component epoxy and ure-
thane protective coatings. When using quick-setting
material (less than 10 minute pot life) a remote mix man-
ifold must be used or materials must mix at the gun.
Quickset manifold 24M398 is recommended for
quick-setting material.
The two pumps are carbide seat severe duty positive
displacement pumps that displace fluid on both strokes.
Over Pressure Protection
The XP systems are not approved for use in hazard-
ous locations unless the base model, all accessories,
all kits, and all wiring meet local, state, and national
codes. See Important Two-Component Material
Information, page 7, to determine the appropriate
location for your particular XP model.
Mechanically linked pumps can create excessive fluid
pressure if the full motor force is applied to only one
of the fluid pumps.
• Cart-Mounted Systems Only: Maximum air pres-
sure set point blow off valves are provided to limit
maximum fluid pressure. Do not remove these
valves.
• Color coded automatic over pressure relief
valves are used on cart-mounted systems to
dump excess fluid pressure back to the supply.
Never plug these return hoses. See Fluid Circu-
lation Manifold with Over Pressure Relief
Valves on page 38.
• When using an XP bare pump package to build a
system, use the over pressure relief valves refer-
enced above.
• Never install individual shut off valves on the “A”
and “B” lines. On cart-mounted systems, com-
mon handles link the fluid control valves.
• On models other than 1:1 mix ratio, a rupture disc
is provided on the small side fluid pump (pumps
72cc and smaller) as a back-up to the over pres-
sure relief valve. If the rupture disc ever opens,
do not operate the machine until the over pres-
sure valve and the rupture disc have been
replaced.
• If changing pump lowers or motor on your sys-
tem, use the correct over pressure relief valves
from the chart on page 39.
