Pressure and Ratio Ratings for President Pumps

WARNING

To reduce the risk of over pressurizing a component, which can result in an explosion and serious injury, never

operate the system at a working pressure higher than the lowest rated component in the system. All fluid side

components such as dispensing valves, regulators, and hoses must have a working pressure equal to or greater

than the pressure given in Column B for each pump model.

Column A gives the maximum fluid pressure developed at 100 psi (0.7 MPa, 7 bar) of incoming air pressure.

Column B gives the minimum working pressure required for all system components, based on the automatic

relief valve settings. Components included by Graco with the models listed meet or exceed this requirement.

Installation

Bare Pumps

Bare pumps are available for those installations which

require a highly customized system. For a safe and

efficient system, Graco recommends that the air and

fluid components supplied with the Wall Mount and

Cart Mount models also be used in customized

systems. Refer to the Parts Drawings on pages 26–37

for part numbers. In addition, the accessories shown in

the Typical Installation drawings and discussed in the

following pages of this manual should be used.

Be sure all accessories are sized properly for the air

and fluid requirements of your system.

Read all instructions in the Installation section for

further details.

NOTES:

1. Models with three displacement pumps always use

the two outer displacement pumps to supply the

resin and the middle displacement pump to supply

the hardener.

1. These pumps always use the two outer displace-

ment pumps to supply the resin and the middle

displacement pump to supply the hardener.

2. Label all pumps, hoses, fluid regulators, etc. to

indicate whether they are for the resin side or

hardener side of the system.

Mounting the Pump

Mount the pump to suit your installation. The bare

pump can be mounted on a wall bracket or on a cart.

See the Mounting Hole Layout on page 42. The Presi-

dent pump and accessories weigh approximately 65 lb

(30 kg). The pump stand and accessories weigh

approximately 55 lb (25 kg).

For a wall mount, be sure the bracket and wall are

strong enough to support the pump, accessories,

plumbing and stress caused by pump operation.

Locate the bracket about 5 ft (1.5 m) above the floor.

Ground the Pumps

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the

system as explained below. Also read

the section FIRE AND EXPLOSION

HAZARD on page 5.

1. Loosen the grounding lug locknut (BB) and washer

(AA).

2. Insert one end of a 14 ga (1.5 mm@) minimum

ground wire (G) into the slot in lug (CC) and tight-

en the locknut securely. See Fig. 3.

3. Connect the other end of the ground wire to a true

earth ground. Order part number 237569 Ground-

ing Clamp and wire.

Installation

Air Control Accessories

Install the accessories in the order shown in Fig. 4.

Mount only the air regulator (E) and a master air valve

(A) at the pump. Mount all other accessories on sepa-

rate wall brackets to reduce stress on the pump inlet.

Note that one air filter (B) can serve multiple pumps by

using an air manifold downstream from the air filter.

WARNING

Bleed-type master air valves (A) are required in the

system in the positions shown in the Typical Instal-

lation drawings. These valves are used during

system pressure relief to relieve air trapped in the

air line. Trapped air can cause the pump to cycle

unexpectedly and result in serious injury from

moving parts, fluid injection, or fluid splashing.

1. Install a bleed-type master air valve (A) in the

pump air inlet.

2. Install an air regulator and gauge (E) to control

pump outlet pressure.

3. Install a pump runaway valve (D) for each feed

pump to automatically shut off the air to the pump

if the pump accelerates beyond the pre-adjusted

setting. A pump which runs too fast can be seri-

ously damaged.

4. Install an air line lubricator (C) for automatic air

motor lubrication.

5. Install an air filter (B) to remove harmful dirt and

moisture from the compressed air supply.

Automatic Pressure Relief Valves

WARNING

To reduce the risk of component rupture, which

could cause serious injury and property damage,

the appropriate automatic pressure relief valve is

required for each fluid on a plural component

pump.

These valves automatically relieve fluid pressure if

the pump output pressure exceeds the valve’s

preset pressure. Over pressurization may occur if

there is a fluid line clog upstream from the valve or

if any other condition exists that causes one of the

pumps to cavitate and direct all fluid pressure to

the other pump(s).

See the List of Models on page 6 to determine

the preset pressure in your system.

Two drainage bottle kits (38) are included with wall

models (unassembled) and stand mount models

(assembled) to catch the drainage if the automatic

pressure relief valves open.

For the wall mount models, assemble the kit as shown

in Fig. 5 and mount it securely to a wall or bracket.

Use the tie wrap, supplied, to hold the hoses out of the

way, if necessary.

WARNING

Fluid emitted from the automatic pressure drain

valves may be at pressures over 3000 psi (21

MPa, 210 bar). Make sure the drain bottles are

securely fastened to the frame or wall so that they

can handle a sudden spurt of pressurized fluid.

Flushing

When to Flush the System

DFlush the system before its first use to remove the

light oil which was left in after factory testing.

DFlush the manifold mixer (N), using the solvent

pump, as frequently during the day as necessary to

avoid exceeding the pot life limit of the material

being pumped.

DFlush frequently enough during regular operation to

prevent clogged passages due to material being

overheated or dried out in any part of the system.

Clogged passages in the heater can be very difficult

to clean and can reduce heating efficiency, flow rate

and pressure.

DFlush the entire system when the system is shut

down for a long period of time. Keep in mind that

some moisture may get into the lines, which could

contaminate the hardener, so flush again before

restarting the system.

How to Operate the Mixer Manifold

To open or close the mixer manifold (N) fluid valves

(LL) push the handle (KK) down to open and up to

close. See Fig. 13.

How to Flush the System

WARNING

If your system is equipped with heaters, always

shut off the main power to the heaters before

flushing. Circulate the fluid through the system for

at least 10 minutes to cool the fluid and the heater.

This reduces the risk of serious injury from burns.

NOTE: For the first time flushing, we recommend

using mineral spirits solvent (also called white spirit) to

flush out the oil. Then flush again using a solvent that

is compatible with the fluid you will be dispensing.

However, be sure the mineral spirits solvent is compat-

ible with the material you will be pumping. If it is not,

check with your fluid supplier to determine an

appropriate solvent for flushing out the light oil.

For flushing only . . .

NOTE: The proportioning pump is not operated during

flushing. The solvent from the feed pumps will flush the

proportioning pump displacement pumps.

1. Place each feed pump intake into a separate 5

gallon grounded pail, containing about 3 gallons

(12 liters) of solvent.

To flush or prime . . .

2. Be sure both of the fluid shutoff valves (Q1) are

open. See Fig. 14.

3. Place a container under the drain valves (P1,P2)

of the mixer manifold (N). See Fig. 13.

4. Be sure the feed pump air regulators (E1,E2) are

at minimum pressure. See Fig. 14.

5. Open the main master air valve (A5). See Fig. 14.

6. Open the hardener pump master air valve (A1).

See Fig. 14.

7. Slowly increase the air regulator (E1) setting until

the pump is running slowly.

8. Open the hardener side drain valve (P1). Open the

mixer manifold handle (KK). See Fig. 13.

9. When the hardener lines are flushed, close the

mixer manifold handle and close the drain valve

(P1). Close the air valve (A1). See Fig. 14.

10. Repeat Steps 6 to 9 for the resin feed pump. The

resin sides uses these parts: regulator (E2), air

valve (A2), drain valve (P2).

To flush the solvent valves . . .

11. Open the hardener solvent flush valve (N1) on the

mixer manifold (N). See Fig. 13.

a. Be sure the solvent pump air regulator (E4) is

at minimum pressure. See Fig. 14.

b. Open the solvent pump main master air valve

(A6) and then open the pump air valve (A4).

See Fig. 14.

c. Release the dispensing valve safety latch.

Hold the dispensing valve firmly against a

grounded pail and trigger it while slowly

opening the solvent pump air regulator (E4).

Operate the pump slowly until the dispense

line is flushed. Release the dispensing valve

trigger and engage its safety latch. Close the

hardener solvent flush valve (N1).

d. Open the resin solvent flush valve (N2) and

repeat Step c. See Fig. 13.

e. Close the solvent line shutoff valve (Q2). See

Fig. 14.

CAUTION

Always close the solvent line fluid shutoff valve (Q2)

after the flushing procedure has been completed.

This will prevent the other fluids from leaking into the

flushing line.

If this is a first time flush . . .

12. Repeat the flushing procedure using a solvent

compatible with the fluid you are going to

dispense.

When you are done flushing . . .

13. Remove the solvent supply from the feed pumps.

Operate the pumps slowly to push all the solvent

out of the lines, then stop the pumps.

If you are not going to use the system . . .

14. Close all air regulators, master air valves and fluid

shutoff valves. Follow the Pressure Relief Proce-

dure on page 21.

WARNING

Always close the air valve (A4) to the solvent pump

before opening the fluid drain valves (P2) to relieve

system pressure. This will reduce the risk of exces-

sive pressure buildup in the opposite component

hose and fittings.

Operation

WARNING

Handling Plural Component Materials

Be extremely cautious when handling plural com-

ponent materials and solvents used with them.

Some are extremely toxic. See the WARNING on

the front cover. Read and follow the coating and

solvent manufacturer’s safety precautions and

warnings, including information regarding protective

clothing, eyewear, and respirators.

When spraying reactive fluids, wear the proper

protective clothing, eye protection, gloves, and

clean air breathing apparatus as prescribed by the

fluid manufacturers recommendations, O.S.H.A.

regulations and as approved by N.O.I.S.H. for the

chemicals being used.

Observe the Pot Life Limit

Flush the mixed fluid out of the mixer, 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 as explained on page

17.

Fill the Throat Packing Nuts

Keep each displacement pump throat packing nut (JJ)

filled with Graco ISO Pump Oil to help prevent fluid

from drying on the displacement rod and damaging the

pump packings. See Fig. 15.

Verify compatibility of the pump oil with the fluids being

used in the pumps. During operation very small

amounts of this fluid are dragged past the seals and

into the pump.

Fig. 15

Check the Drainage Bottles and Hoses

WARNING

To reduce the risk of serious injury and property

damage, regularly check and clean the drain hose

and bottle for the automatic pressure relief valve.

If material is allowed to dry in and clog the drain

hose, the automatic pressure relief valve may not

fully release the fluid pressure if it opens or may

cause the drain hose to burst.

Check the drain hose and bottle (38) at the start of

each shift, and whenever there is an imbalance of

material, to see if the automatic pressure drain valve

has released material into the bottles. Clean the hose

and bottle as needed. Regularly check the drain hose

for cuts, leaks, or bulges and replace damaged

components before using the system. See Fig. 16.

Fig. 16

38

02948A

Monitor the Material Supply

CAUTION

Establish a rigid system for monitoring the material

supply to prevent the pumps from running dry. A

sudden lack of material in one pump may cause

many system problems, including air entrapment,

spitting of the fluids, fluid “crossovers”, pump

damage, downtime, and added system stresses.

Never allow the feed pump or solvent pump containers

to run dry. A dry container allows air to be pumped into

the system and causes incorrect proportioning. A dry

pump will quickly accelerate to a high speed, and may

damage itself and the other displacement pump be-

cause it causes a pressure rise in the other pump. If a

supply container becomes dry, stop the pump immedi-

ately, refill the container, and prime the system. Be

sure to eliminate all the air from the system.

NOTE: The pump runaway valve mentioned on page

11 of the Installation section shuts off the pump if the

pump speed accelerates quickly.

308224 19

Operation

Startup

WARNING

To reduce the risk of serious bodily injury, including

fluid injection, splashing in the eyes or the skin, and

property damage, never exceed the maximum air

and fluid working pressure of the lowest rated

component in your system. See Equipment Mis-

use Hazard, System Pressure, on page 3.

1. Install full containers of resin and hardener at the

feed pumps.

2. To prime the system, follow Steps 2 to 11 of the

Flushing procedure on page 17.

3. Turn on the heaters, if used, and allow them to

warm up for 10 minutes.

4. Open the feed pump air valves (A1,A2). Adjust the

air regulators (E1,E2) just enough to start the

pumps operating slowly.

5. Open the proportioning pump air valve (A3) and

slowly open the regulator (E3) to start the propor-

tioning pump.

6. Open the mixer manifold (N) and trigger the

dispense valve (S).

7. Set the air pressure to the feed pumps at 88 psi

(0.6 MPa, 6 bar) or 25% of proportional pressure

at the fluid outlets, whichever is less. Use the

gauges (J1) to monitor this pressure. Higher

pressures may prevent the proportioning pump

inlet ball checks from setting properly.

8. Set the air pressure to the proportioning pump (H)

to obtain the required fluid pressure. Refer to the

proportioning pump chart on page 6 for the fluid

to air pressure.

9. While triggering the dispensing valve, check the

fluid outlet pressure gauges (J2) and make note of

the pressures indicated. Check the gauges

frequently during operation. These notes will help

to analyze any problems that may occur since a

change in displacement pump performance will be

indicated by a change in pressure gauge

readings.

NOTE: A pressure drop does occur during pump

stroke changeover.

NOTE: Flush the mixer manifold frequently during the

day’s operation. Follow Step 11 on page 17.

Operation

Checking the Mix Ratio

NOTE: Since this is a fixed ratio system, you typically

do not have to check the mix ratio.

If the mixed fluid does not cure or harden properly,

check the ratio of resin to hardener.

1. Flush the mixer manifold; see Step 11 on page 17.

2. Follow the Pressure Relief Procedure on page .

3. Open the mixer manifold (N).

4. Set the operating pressure for the pumps. See

Steps 7 and 8 on page 19.

5. Release the dispensing valve trigger and engage

the safety latch.

6. Close the mixer manifold (N).

7. Open the hardener side drain valve (P2) about

three turns. Open the resin side drain valve (P1)

about 1 turn. This prevents the pressure from

building up on the hardener pump, which would

cause the automatic pressure relief valve to open.

8. Place a grounded metal pail under the drain

valves.

9. Open the mixer manifold.

10. While observing the pump outlet gauges (J2),

adjust the resin and hardener drain valves (P1,P2)

until the gauges show your normal operating

pressure.

NOTE: The pressure must be within 20% of the orig-

inal spraying pressure to get a usable test.

11. Close the mixer manifold. Put a separate sampling

container under each drain valve.

12. Open the mixer manifold to draw a sufficient

sample.

13. As you close the mixer manifold, check the pump

outlet gauges (J2) again to make sure they are at

your normal operating pressure.

NOTE: If the fluid pressure is not within 20% of the

normal operating pressure, flush the mixer manifold

again and take another sample. If the sample ratio is

incorrect, refer to the Troubleshooting chart on page

22. If the ratio is correct, the problem is with one of the

other system components.

14. Compare the volume of the sampling containers. If

the ratio is not correct, refer to the Troubleshooting

chart on page 22. If the ratio is correct the problem

is one of the other components.

15. Close the drain valves (P1,P2).

Shutdown and Care of the System

Pressure Relief Procedure

WARNING

INJECTION HAZARD

The system pressure must be manually

relieved to prevent the system from

starting or spraying accidentally. Fluid

under high pressure can be injected through the

skin and cause serious injury. To reduce the risk of

an injury from injection, splashing fluid, or moving

parts, follow the Pressure Relief Procedure

whenever you:

Dare instructed to relieve the pressure,

Dstop spraying,

Dcheck or service any of the system equipment,

Dor install or clean the spray tips.

1. Engage the dispensing valve safety latch.

2. Shut off the feed pump and proportioning pump air

regulators and bleed-type master air valves.

3. If the system has heaters, circulate the fluid for at

least 10 minutes to cool the heated fluid and

heater.

4. Disengage the dispensing valve safety latch.

5. Hold a metal part of the dispensing valve firmly to

the side of a grounded metal pail, and trigger the

dispensing valve to relieve pressure.

6. Engage the safety latch.

7. Open the mixer manifold drain valves (required in

your system), having a container ready to catch

the drainage. Close the valves immediately.

8. Use the solvent pump to flush the mixer manifold

valves.

If you suspect that the nozzle or hose is completely

clogged, or that pressure has not been fully relieved

after following the steps above, very slowly loosen the

nozzle or hose end coupling and relieve pressure

gradually, then loosen completely. Now clear the

nozzle or hose.

System Shutdown

To shut the system down, shut off the air to all pumps,

trigger the dispensing valve into a grounded metal

waste container. Close the mixer manifold valves.

Flush all the mixed fluid out of the mixer manifold,

hoses and dispensing equipment. See page 17. Then

follow the Pressure Relief Procedure.

Cleaning the Pump Inlet Strainer

If the fluid pressure from the feed pump to the propor-

tioning pump cannot be maintained on the propor-

tioning pump intake gauge (J), check and clean the

strainer (V).

Care of the Pump Throat Packing Nuts

Keep the throat packing nuts filled with appropriate

lubricant and check the tightness of the packing nut

weekly. See Fig. 19. The packing nut should be tight

enough to prevent leakage; no tighter. Too tight an

adjustment causes the packings to bind or wear pre-

maturely and leak. Always follow the Pressure Relief

Procedure before adjusting the packing nut.

Fig. 19

30822422

Troubleshooting

WARNING

To reduce the risk of serious bodily injury, always

follow the Pressure Relief Procedure on page 21

whenever you shut off the pump, when checking or

servicing any part of the dispensing system, when

installing, cleaning or changing fluid tips, and

whenever you stop dispensing.

WARNING

Never operate the pump with the air motor plate

removed, to reduce the risk of serious bodily injury,

including amputation, from moving parts inside the

air motor housing.
