Fluid Compatibility of Accessories
When
selecting system components to supply the
adhesive and activator
, consider the following:
D
Adhesives and activators are water-based and
corrosive. A
void carbon steel, unplated brass,
copper
, and aluminum. Stainless steel, nickel-
plated brass and most plastics are usually accept
-
able.
D
Piston pumps are not recommended for use with
adhesives as they are often shear sensitive and will
coagulate in your equipment. Stainless steel
pressure pots function well in place of a pump and
fluid pressure regulator. On drum or tote tank
supplied systems, plastic diaphragm pumps are
often used.
D
Some adhesives will coagulate in fluid pressure
regulators due to shear
. Consult with the fluid
supplier for regulator recommendations.
D
Refer to Fig. 1 and see Form No. 305–591 for the
accessories recommended to install the system.
Consult with the fluid supplier or Graco for specific
