Moisture Sensitivity of Isocyanates
311882C 7
Moisture Sensitivity of
Isocyanates
Isocyanates (ISO) are catalysts used in two component
foam and polyurea coatings. ISO will react with moisture
(such as humidity) to form small, hard, abrasive crystals,
which become suspended in the fluid. Eventually a film
will form on the surface and the ISO will begin to gel,
increasing in viscosity. If used, this partially cured ISO
will reduce performance and the life of all wetted parts.
To prevent exposing ISO to moisture:
• Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere. Never
store ISO in an open container.
• Use moisture-proof hoses specifically designed for
ISO, such as those supplied with your system.
• Never use reclaimed solvents, which may contain
moisture. Always keep solvent containers closed
when not in use.
• Never use solvent on one side if it has been
contaminated from the other side.
• Always lubricate threaded parts with Part 217374
ISO pump oil or grease when reassembling.
Isocyanate Hazard
Foam Self-Ignition
Keep Components A and B
Separate
Changing Materials
• When changing materials, flush the equipment
multiple times to ensure it is thoroughly clean.
• Check with your material manufacturer for chemical
compatibility.
• Some materials use catalyst on the A side, but
some applications may use catalyst on the B side.
• Epoxies often have amines on the B (catalyst) side.
Polyurethanes often have amines on the B (resin)
side.
The amount of film formation and rate of
crystallization varies depending on the blend of
ISO, the humidity, and the temperature.
Read material manufacturer’s warnings and material
MSDS to know the specific hazards of isocyanates.
Use equipment in a well-ventilated area. Wear
respirator, gloves, and protective clothing when using
isocyanates.
Some materials may become self-igniting if applied
too thick. Read material manufacturer’s warnings and
material MSDS.
CAUTION
To prevent cross-contamination of the equipment’s
wetted parts, never interchange component A and
component B.

Setup
8311882C
Setup
1. Apply thread sealant to the male threads of the air
needle valve (48) and the quick disconnect fitting
(49) and install. See FIG. 4
2. Apply thread sealant to the male outlet fitting (not
supplied) and insert into the outlet port. See FIG. 5.
3. Use labels (70) provided to identify the appropriate
pump for your material. See FIG. 5 and FIG. 6. When
applying component labels (70) to pump cap (1)
make sure you do not cover the hole in the cap.
4. Lubricate the bung adapter inside diameter and
mounting threads. Ensure the gasket is in place and
screw the bung adapter (51) securely into the bung-
hole of the drum. Insert the pump through the
adapter and lock it in place. See FIG. 7.

5. Install air line (3/8 in. (76 mm) ID minimum) with
quick disconnect air coupler (52) provided. See FIG.
8.
Grounding the System
To reduce the risk of static sparking, ground the pump
and all other equipment used or located in the pumping
area. Check your local electrical code for detailed
grounding instructions for your area and type of
equipment. Ground all of this equipment.
1. Pump: Connect Ground Wire (Y) to grounding screw
(72) and tighten the screw securely. See FIG. 9.
Connect the other end of the wire to a true earth
ground. Make certain to comply with all National,
State, and Local Electrical Codes.
2. Air compressor: according to manufacturer’s recom-
mendations.
3. Fluid hoses: use only grounded hoses with a maxi-
mum of 300 ft (91 m) combined hose length to
ensure grounding continuity. Refer to Hose Ground-
ing Continuity.
4. Dispensing valve: grounding is obtained through
connection to a properly grounded fluid hose and
pump.
5. Object being sprayed: according to local code.
6. Fluid supply container: according to local code.
7. All solvent pails used when flushing, according to
local code. Use only metal pails, which are conduc-
tive. Do not place the pail on a non–conductive sur-
face, such as paper or cardboard, which interrupts
the grounding continuity.
8. To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
spray gun/dispensing valve firmly to the side of a
grounded metal pail, then trigger the gun/valve.

Operation
10 311882C
Operation
Pressure Relief Procedure
1. Engage trigger lock.
2. Close the bleed-type master air valve.
3. Disengage the trigger lock.
4. Hold a metal part of the dispense valve firmly to a
grounded metal pail. Trigger the valve to relieve
pressure.
5. Engage the trigger lock.
6. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Leave
drain valve(s) open until you are ready to dispense
again.
7. If you suspect the nozzle or hose is clogged or that
pressure has not been fully relieved after following
the steps above, VERY SLOWLY loosen the hose
end coupling to relieve pressure gradually, then
loosen completely. Clear hose or nozzle obstruction.
Flushing
1. Follow Pressure Relief Procedure, page 10.
2. Place suction tube in grounded metal drum contain-
ing cleaning fluid.
3. Set pump to lowest possible fluid pressure, and start
pump.
4. Hold a metal part of the dispense valve firmly to a
grounded metal pail. Trigger the dispense valve until
clean solvent dispenses.
5. Remove valve from hose.
6. Follow Pressure Relief Procedure, and remove
fluid filter and soak in solvent. Replace filter cap.
Daily Startup
1. Verify that the air needle valve is closed.
2. Connect the air line quick disconnect coupler to the
transfer pump
3. Turn on the main air supply.
4. Slowly open the air needle valve until the transfer
pump runs slowly.
5. Use the air needle valve to control the pump speed.
Daily Shutdown
1. Disconnect air line coupler.
2. When air pressure is bled off, close the air line nee-
dle valve.
Trapped air can cause the pump to cycle unexpectedly,
which could result in serious injury from splashing or
moving parts.
Trapped air can cause the pump to cycle unexpectedly,
which could result in serious injury from splashing or
moving parts.
• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the
fluid being dispensed and the equipment wetted
parts.
Caution
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed and could cause personal injury and/or dam-
age to the pump. If the pump accelerates quickly or
starts running too fast, stop it immediately and check
the fluid supply. If the supply container is empty or air
has been pumped into the lines, refill the container
and prime the pump and the lines with fluid, or flush
and leave it filled with a compatible solvent. Be sure to
eliminate all air from the fluid system.
Do not attempt to operate pump unless it is securely
mounted in a drum.

Air Motor Repair
311882C 11
Air Motor Repair
1. Remove cap (1), cylinder (4), and square gaskets
(3*). Inspect all parts, including spring under cap
(not shown in FIG. 10) for damage and replace if
necessary. See FIG. 10. Unscrew by hand or use a
chain wrench to prevent distortion of the cylinder’s
shape.
2. Loosen set screw (18) and unscrew air piston head
(5). If necessary to assist turning, wedge a screw-
driver blade between the screw heads (16) and the
hex cap (9). Inspect o-rings (13* and 15*) for dam-
age and replace if necessary. During reassembly,
do not add thread lock paste to the piston head.

pinched. See FIG. 11.
3. Remove 3 screws (16) from top of air piston.
Remove valve disk (8) and spacers (11). Remove
washer (6*) from valve disk. Inspect all parts for
damage. During reassembly, ensure spacers (11)
do not pinch gaskets (10). See FIG. 12.
4. Place pin tool (69) in piston hole to prevent piston
from turning. Use second pin tool (69) to unscrew
piston cap (17) and separate from piston (21) to
expose dowel pin (19). See FIG. 13.
