Important Isocyanate (ISO) Information

Important Isocyanate (ISO) Information

Isocyanates (ISO) are catalysts used in two component materials.

Isocyanate Conditions

Spraying or dispensing materials containing isocyanates creates potentially harmful mists, vapors, and atomized particulates.

Read material manufacturer’s warnings and material

MSDS to know specific hazards and precautions related to isocyanates.

Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventilation in the work area. If sufficient ventilation is not available, a supplied-air respirator is required for everyone in the work area.

To prevent contact with isocyanates, appropriate personal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.

NOTICE

Partially cured ISO will reduce performance and the life of all wetted parts.

• Always use a sealed container with a desiccant dryer in the vent, or a nitrogen atmosphere. Never store ISO in an open container.

• Keep the ISO pump wet cup or reservoir (if installed) filled with appropriate lubricant. The lubricant creates a barrier between the ISO and the atmosphere.

• Use only moisture-proof hoses compatible with

ISO.

• Never use reclaimed solvents, which may contain moisture. Always keep solvent containers closed when not in use.

• Always lubricate threaded parts with an appropriate lubricant when reassembling.

NOTE: The amount of film formation and rate of crystallization varies depending on the blend of ISO, the humidity, and the temperature.

Keep Components A and B

Separate

Cross-contamination can result in cured material in fluid lines which could cause serious injury or damage equipment. To prevent cross-contamination:

• Never interchange component A and component

B wetted parts.

• Never use solvent on one side if it has been contaminated from the other side.

Moisture Sensitivity of

Isocyanates

Exposure to moisture (such as humidity) will cause ISO to partially cure; forming 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.

Changing Materials

NOTICE

Changing the material types used in your equipment requires special attention to avoid equipment damage and downtime.

• When changing materials, flush the equipment multiple times to ensure it is thoroughly clean.

• Always clean the fluid inlet strainers after flushing.

• Check with your material manufacturer for chemical compatibility.

• When changing between epoxies and urethanes or polyureas, disassemble and clean all fluid components and change hoses. Epoxies often have amines on the B (hardener) side. Polyureas often have amines on the B (resin) side

Installation

Installation

Prepare the Operator

All persons who operate the equipment must be trained in the operation of all system components as well as the proper handling of all fluids. All operators must thoroughly read all instruction manuals, tags, and labels before operating the equipment.

Prepare the Site

Compressed Air

• Ensure that you have an adequate compressed air supply.

• Bring a compressed air supply line from the air compressor to the pump location.

• Be sure all air hoses are properly sized and pressure-rated for your system. The air hose should have a 3/8 npt(m) thread and minimum 3/8” (9.5 mm) ID.

• Use only electrically conductive hoses. A quick disconnect coupling may be used.

Work Area

• Keep the site clear of any obstacles or debris that could interfere with the operator's movement.

• Have a grounded, metal pail available for use when flushing the system.

Wall Mount Packages

Before installing a wall mounted package, ensure the wall can support the weight of the pump, bracket, hoses and accessories, as well as the stress caused during operation.

1.

Position the wall bracket about 1-1.5 m (3-5 ft) above the floor. For ease of operation and service, make sure the pump air inlet, fluid inlet, and fluid outlet ports are easily accessible.

2.

Using the wall bracket as a template, drill 10 mm

(0.4 in.) mounting holes in the wall. Wall mounting

dimensions are shown on page 51.

3.

Attach the bracket to the wall. Use 3/8 in. (9 mm) screws that are long enough to anchor the pump securely during operation.

NOTE: Be sure the bracket is level.

Air Line Accessories

Install the following accessories in F

IG

. 1, using adapters as necessary.

• An air filter (B) removes harmful dirt and moisture from the compressed air supply.

• A second bleed-type air shutoff valve (A) isolates the air line accessories for servicing. Locate upstream from all other air line accessories.

14 333309G

Installation

Grounding

The equipment must be grounded to reduce the risk of static sparking. Static sparking can cause fumes to ignite or explode. Grounding wire provides an escape path for static electric current.

The following components must be grounded.

1.

Pump

See F IG . 4. Verify that the ground screw (GS) is attached and tightened securely to the air motor.

Connect the other end of the ground wire (S) to a true earth ground.

S

GS ti12914a

F IG . 4. Ground screw and wire

2.

Pump fluid hoses

Use only electrically conductive fluid hoses. Check electrical resistance of hoses. If total resistance to ground exceeds 25 megohms, replace hose immediately.

3.

Air compressor

Follow manufacturer's recommendations.

4.

Spray gun

Ground through connection to a properly grounded fluid hose and pump.

5.

Fluid supply container

Follow your local code.

6.

Object being sprayed

Follow your local code.

7.

Solvent pails used when flushing

Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts the grounding continuity. All solvent pails used when flushing must be grounded according to local code.

NOTE: To maintain grounding continuity when flushing or relieving pressure, hold a metal part of the spray gun firmly to the side of a grounded metal pail, then trigger the gun.

333309G 15

Setup

Setup

See F

IG

. 2.

1.

Install suction hoses (VA, VB) to the pump fluid

inlets (U). See page 46.

2.

Connect solvent supply (DD) to solvent flush inlet

(J).

3.

Attach one end of the gun fluid supply hose (M) to the mixer (X) outlet.

4.

Attach one end of the gun air supply hose (N) to gun air pressure regulator (D) atomizing air port.

5.

Attach remaining end of the gun air supply hose (N) to air inlet at base of gun (L).

6.

Connect gun fluid supply hose (M) to the base of the gun (L) at swivel (K).

7.

Clip gun fluid supply hose (M) and gun air supply hose (N) together with the supplied hose clips (qty. of 7). Space clips as needed.

8.

Apply lens cover to both regulator gauge lenses.

9.

Verify that suction hose (VA, VB) fittings are tight.

NOTE: Loose suction hose fittings allow air to enter into the proportioning pump resulting in the fluid ratio to be altered.

Feed Systems

Ensure your feed systems are designed to supply twice the volume used by each component. This supply pump pressure should never exceed 25% of the proportioner output pressure or 250 psi (16 bar) maximum supply pressure.

Example: 4:1 proportioner. 2.0 lpm output, 100 bar.

4:1 ratio at 2.0 lpm = 1.6 lpm of “A” component and.4 lpm of component “B”.

• “A” feed pump needs to have a 3.2 lpm capacity at a max of 250psi (16 bar).

• “B” feed pump needs to be at least.8 lpm at 250 psi max.

Material supply is critical to proper proportioner operation. Material must fill the proportioner cylinders on their upstroke totally to eliminate a “diving” of the cylinders on the top change–over. This “diving” will also be seen as a pressure drop at the change over. This will cause an off ratio condition.

NOTICE

Using more supply pressure than necessary to fully supply the proportioning cylinder can cause varying atomization, inconsistent spray pressure, and incorrect fluid ratios.

Connect Air Lines

See F

Setup

A and B Components Checking the Mix Ratio

Cross-contamination can result in cured material in fluid lines which could cause serious injury or damage equipment. To prevent cross-contamination:

• Never interchange component A and component

B wetted parts.

• Never use solvent on one side if it has been contaminated from the other side.

NOTE: Material suppliers can vary in how they refer to plural component materials.

Be aware that when facing the manifold on the proportioner:

• Component A is on the left side.

• Component B is on the right side.

For all machines:

• The A side is intended for polyols, resins, and bases.

• If one of the materials being used is moisturesensitive, that material should always be in the B side.

• The B side is intended for ISO, hardeners, and catalysts.

NOTE: For machines with material volume ratios other than 1:1, the higher volume side is typically at the A side.

Polyester Model 24W609: This model is intended for use with split-batch polyester applications. The A side will contain polyester, resin, and the promoter. The B side will contain polyester, resin, and the activator.

The pump must be operating in order to accurately check the proportioning ratio of the pumps. The outlet pressures at the pumps must be maintained at a minimum level of 4 times that of the inlet pressures.

When the mix manifold is removed to check the mix ratio, a flow restrictor will be needed to simulate the pressure conditions during normal operation. The preferred flow restrictor is a small diameter, 1/16 in. ID, 1/2 in. (13 mm) long steel tube, coupled to the fluid supply hoses. A needle-type flow control valve could also be used. Contact your Graco distributor for assistance in selecting the proper type of flow restrictor for your application.

If the mixed fluid does not cure or harden properly, check the ratio of part A to part B. To check the ratio:

1.

Relieve the pressure, see page 19.

2.

Flush the mixed fluid out of the mix manifold, dispensing lines, and equipment.

3.

Disconnect the fluid hoses from the mix manifold inlet, taking note of which hose was connected to which valve.

4.

Place the hose ends into a waste container. Set two graduated cylinders of the same size next to the waste container. See F IG

. 5.

5.

Set the air pressure to the proportioning pumps at zero pressure. Open the air shut off valves to the feed pumps and proportioning pump.

6.

Turn up air pressure until fluids are flowing freely, at exactly the same time, move the hoses over the cylinders – part A hose over one cylinder and part B hose over the other.

333309G 17

Setup

7.

When you have a large enough sample, move both hoses back into the waste containers, at exactly the same time. Then shut off the air to all the pumps.

8.

Compare part A volume to part B volume. If the ratio is not correct, refer to the Troubleshooting Chart

on page 31 for further information on how to correct

the ratio.

9.

Connect the fluid hoses back to the mix manifold inlet.

NOTICE

Be sure to connect the hoses back to the same valves they had originally been connected to. The mix manifold could be damaged by reversing them. See F

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure

Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.

1.

Engage the gun trigger lock, if present.

2.

See F IG . 2. Turn off the bleed-type master air valve

(E) and air to supply pumps, if present.

3.

Disengage the gun trigger lock, if present.

4.

Hold a metal part of the gun firmly to a grounded metal waste container. Trigger the gun to relieve fluid pressure.

7.

If you suspect that pressure has not been fully relieved after following the steps above, check the following: a.

The spray tip may be completely clogged. Very slowly loosen the air cap retaining ring to relieve pressure in the cavity between the ball/seat shutoff and the plugged tip. Clear the tip orifice.

b.

The gun fluid filter or the fluid hose may be completely clogged. Very slowly loosen the hose end coupling at the gun and relieve pressure gradually. Then loosen completely to clear the obstruction.

c.

After following the steps above, if the spray tip or hose still seems completely clogged, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. With tip removed, trigger gun into waste container.

5.

Engage the trigger lock, if present.

6.

Open all fluid drain valves (W) in the system, having a waste container ready to catch the drainage.

Leave the drain valve(s) open until you are ready to spray again.

Do not turn on atomizing air supply. Fluid pressure is controlled by the air pressure supplied to the pump (pump air pressure regulator). Set fluid pressure at low starting pressure.

• For low viscosity fluids (less than 25 sec, #2

Zahn cup) with lower percent solids (typically less than 40%), start at 300 psi (2.1 MPa, 21 bar) at pump outlet.

• For fluids with higher viscosity or higher solids content, start at 600 psi (4.2 MPa, 42 bar).

Using the Proportioning Pump

System

To reduce the risk of serious injury, including fluid injection:

• Do not exceed the maximum air and fluid working pressure of the lowest rated component in your system.

• Always close the air supply valve to the pump before opening the fluid drain valves to relieve system pressure. This will reduce the risk of excessive pressure buildup in the opposite component hose and fittings.

When the system is primed and operating, check the fluid outlet pressure gauges. Check the gauges frequently while using the system and note the pressures.

These notes will be helpful in analyzing problems that may occur, as a change in the displacement pump performance will be indicated by a change in the pressure gauge readings.

NOTE: A pressure drop does occur during pump stroke changeover.

1.

Set the air pressure to the proportioning pump to obtain the fluid pressure you require.

2.

Set the air pressure to the feed pumps at a pressure that will not give more than 25% of sprayer outlet pressure at their fluid outlets.

NOTE: Pressures greater than 25% may prevent the proportioning pump inlet ball checks from seating properly.

3.

Point the spray gun into a grounded metal waste container and trigger the spray gun to purge air out of the dispensing lines. After all air has been purged from the lines, release the trigger and engage the gun trigger lock.

NOTE: The pumps will start and stop as the gun is triggered and released.

26 333309G

Operation

Monitoring the Proportioner

During Operation

When the spray gun is triggered:

• Both A and B fluid pressure gauges should be increasing and decreasing in pressure at the same time.

• If one pressure or the other increases while the other decreases the proportioner is not working correctly. The cause should be determined and corrected.

• The most typical time for pressure variations to occur is right after the top change over. This pressure variation is caused by one of the double acting piston pumps “A” or “B” cavitating during the up, or fill stroke, and then not having fluid to pump until it travels down to the filled level. Cavitation causes ratio errors and should not be allowed at any time while spraying.

Changing ratios

Remove Pump Lowers

Remove pump lowers as needed (change only the pump(s) required to achieve the new ratio)

1.

Disconnect the suction tube assembly from the pump inlet.

2.

Disconnect the Fluid filter and safety relief valve assembly from the pump outlet port.

3.

Remove coupler nut (24) from connecting rod (36) using wrench on coupler nut and flats on the connecting rod. Do not lose keepers (23 Qty. 2) required.

4.

Remove retaining ring (22) using a spanner wrench or hammer and punch.

5.

Remove pump assembly by lowering out the bottom of the mounting plate.

Install Replacement Lower for New Ratio

1.

Install pump adapter (29) and new pump. Thread adapter (29) flush with top threaded upper pump housing. Secure in position by locking in place with jam ring on pump assembly. See F IG . 6.

2.

Install pump into mounting plate and retain in position with lock ring (22) loose fit.

3.

Install coupler nut (24) and keepers (23, qty. 2) on pump displacement rod. Thread coupler nut (24) to connector rod (36). Tighten and torque to 75-80 lb-ft

(102-108 N•m). If changing to a 25 cc fluid section, the pump connecting rod (36), keepers (23, qty 2) and connector nut (24) need to be replaced with the

25cc parts. For the 25cc lower coupler nut (24) torque to 25-30 lb-ft (31-35 N•m) See

Adjust Pump Assembly for Balanced Yoke

Forces

At each ratio setup the pump assembly must be adjusted to balance the yoke forces. To adjust the pump assembly:

1.

Loosen mounting plate screw (44, 2 locations)

2.

Loosen yoke bolts (33, 2 locations).

3.

Loosen Tie rod nuts (14, 4 locations)

4.

Slide the yoke (32) until the desired ratio marks on the yoke (32) align with the center line mark on the connector (31). See Detail A.

5.

Remove yoke assembly screws (33, 2 locations), clean threads and apply medium strength thread adhesive. Re-install screws (33, 2 locations) and tighten the yoke assembly screws (33, 2 locations), while maintaining the mark alignment. Torque to 40 lb-ft (47-54 N•m).

6.

Position the fluid assembly vertically under the yoke and tighten the tie rod nuts (14), ensure washers

(15) are in place. Torque to 45 lb-ft (68-80 N•m).

NOTICE

Verify that fluid pumps are aligned vertically under the yoke position. If they are not aligned correctly, side loading of motor and fluid pumps will occur, causing premature wear to seals and bearings.

7.

Re-tighten mounting bracket screws (44) and torque to 35 lb-ft. (47 N•m)

Cycle the pump slowly and observe up and down stroke changeover verifying correct operation. If binding is observed, re-align fluid pumps by repeating step 6.

NOTE: 1:1 and 6:1 ratios have yoke and pump positioned against yoke and plate slot ends. Adjusted full left or right positions.

Maintenance

Maintenance

Care of the Pump

NOTICE

Do not allow the supply containers to run dry of the fluid being pumped. A dry container allows air to be pumped into the system and can cause incorrect proportioning. One dry displacement pump can damage the other displacement pump by causing a pressure rise in the other pump.

Preventive Maintenance

Schedule

The operating conditions of your particular system determine how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system.

• If a supply container is dry, stop the pump immediately and relieve the pressure. Refill the container, and prime the system. Be sure to eliminate all of the air from the system.

• Keep the throat packing reservoirs one-half filled with TSL.

• Observe the pot life limit. Flush the mixed fluid out of the mix manifold, dispensing lines and equipment before it hardens.

• Flush the complete system, when necessary to prevent the fluids from hardening in the equipment and hoses.

• Check the fluid manufacturer’s instructions for fluid shelf life, and flush the entire system before this time is reached.

• Flush the system with a compatible solvent.

• With heavy fluids, flushing solvents could channel through the fluid, leaving a coating of fluid on the inside of the hoses. Allow pump to flush at higher cycle rates to create turbulent flow and better cleaning action. Disconnect the hoses and clean the fluid out with a rag and wire or a ramrod type cleaner, or use a solvent and air purge to agitate the solvent, and flush until the mix manifold, hose, and gun are clean.

• For daily or long term shutdown stop the pump at the bottom of the stroke to protect the displacement rod from dried or cured material.

333309G

Tighten Threaded Connections

Before each use, check all hoses for wear or damage.

Replace as necessary. Check that all threaded connections are tight and leak-free.

Flush the Pump

To avoid fire and explosion, always ground equipment and waste container. To avoid static sparking and injury from splashing, always flush at lowest possible pressure.

When to Flush the Pump:

• Before first use

• When changing colors or fluids

• Before repairing equipment

• Before fluid dries or settles out in a dormant pump

(check the pot life of catalyzed fluids)

• Before storing the pump

Flushing Guidelines

• Flush at the lowest pressure possible.

• Flush with a fluid that is compatible with the fluid you are pumping and with the wetted parts in your system.

• Check with your fluid manufacturer or supplier for recommended flushing fluids and flushing frequency.

• If the pump is to be stored for any period of time, and you are pumping water-based fluid, first flush it with water, then with mineral spirits to protect the pump parts.

29

Maintenance

Wet Cup

The wet cup helps to provide consistent lubrication for the pump packings and to keep exposed rod from being coated with dried paint. To maintain the wet cup:

1.

Fill the wet cup one-half full with Graco Throat Seal

Liquid (TSL).

2.

Maintain level daily.

Fluid Pressure Relief Valves

The fluid pressure relief valves are used to prevent pumps from generating pressures higher than they system rated pressure. If an overpressure situation occurs the valve will open and discharge fluid from the bottom relief port. Do not modify, remove, or plug the pressure relief valve.

Storage and Extended

Shutdown

NOTICE

Before flushing stop the pump at the bottom of its stroke to keep fluid from drying on the exposed displacement rod and damaging throat packings.

Water or moist air can cause material residue in ball checks and packings to cure.

• Never leave the pump filled with water or air.

• After normal flushing, flush the pump again with mineral spirits or oil-based solvent; relieve the pressure; and leave the mineral spirits in the pump.

Materials that cure when exposed to air may defeat the ability of the pressure relief valve to relieve an overpressure condition, resulting in burst components and serious injury

Refer to separate relief valve manual for additional details. See


Lubrication

An accessory air line lubricator provides automatic air motor lubrication. For daily, manual lubrication:

1.

Disconnect the regulator

2.

Place about 15 drops of light machine oil in the pump air inlet

3.

Reconnect the regulator.

4.

Turn on the air supply to blow oil into the motor.

Filter plugged.

Air supply to flush pump turned off

Fix hose and fitting leaks

Clean or repair proportioning pump

Clean filters

Turn on air supply

Air supply pressure to flush pump set too low

Increase air supply pressure

Mix manifold solvent valves not “on” Open flush valves and gun

Gun not triggered Trigger spray gun

Mix Manifold or mixed material hose plugged

Repair and replace mix manifold and mixed material hoses

* To determine if the fluid hose or gun is obstructed, relieve the pressure. Disconnect the fluid hose and place a container at the pump fluid outlet to catch any fluid. Turn on the air just enough to start the pump. It the pump starts when the air is turned on, the obstruction is in the hose or gun.
