Fluid Compatibility of Accessories
When selecting system components to supply the
adhesive and activator, consider the following:
Adhesives and activators are water-based and
corrosive. Avoid carbon steel, unplated brass,
copper, and aluminum. Stainless steel, nickel-
plated brass and most plastics are usually accept-
able.
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.

Some adhesives will coagulate in fluid pressure
regulators due to shear. Consult with the fluid
supplier for regulator recommendations.
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
recommendations.
