WARNING

Moisture Sensitivity of Isocyanates

4311882T

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.

Installation

System Accessories

To ensure maximum pump performance, be sure that all

accessories used are properly sized to meet your sys-

tem’s requirements. See Accessories, page 20.

Air Line Accessories

Install the following accessories in the order shown in

the Typical Installation for Lubrication Applications,

using adapters as necessary:

An air line lubricator (B) provides automatic air motor

lubrication.

A bleed-type master air valve (D) is required in your

system to relieve air trapped between it and the air

motor when the valve is closed (see the WARNING on

left). Be sure the bleed valve is easily accessible from

the pump, and is located downstream from the air regu-

lator.

An air line filter (C) to remove harmful dirt and moisture

from the compressed air supply.

A second bleed-type air valve (D) isolates the air line

accessories for servicing. Locate upstream from all

other air line accessories.

Fluid Line Accessories

A fluid drain valve (E) is required in your system to

relieve fluid pressure in the hose and gun (see the

WARNING on left). Install the drain valve so that it

points down and the handle points up when the valve is

opened.

A bleed-type master air valve (D) and a fluid drain

valve (E) are required in your system, to help reduce

the risk of serious injury, including splashing fluid in

the eyes or on the skin, and injury from moving parts

when you are adjusting or repairing the pump.

The bleed-type master air valve (D) relieves air

trapped between this valve and the pump after the

pump is shut off. Trapped air can cause the pump to

cycle unexpectedly and result in serious injury,

including amputation. Install the valve close to the

pump.

The fluid drain valve (E) helps relieve pressure in the

displacement pump, hose, and dispensing valve

when shutting off the pump. Actuating the dispensing

valve to relieve pressure may not be sufficient, espe-

cially if there is a clog in the hose or the dispensing

valve.

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 F

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

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 obstruc-

tion.

Flushing

1. Follow Pressure Relief Procedure, page 11.

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 unexpect-

edly, which could result in serious injury from splashing

or moving parts.

Trapped air can cause the pump to cycle unexpect-

edly, 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.
