WARNING

EQUIPMENT MISUSE HAZARD

Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury.

DThis equipment is for professional use only.

DRead all instruction manuals, tags, and labels before operating the equipment.

DUse the equipment only for its intended purpose. If you are not sure, call your Graco distributor.

DDo not alter or modify this equipment. Use genuine Graco parts and accessories.

DCheck equipment daily. Repair or replace worn or damaged parts immediately.

DDo not exceed the maximum working pressure stated on the equipment or in the Technical Data

for your equipment. Do not exceed the maximum working pressure of the lowest rated component

in your system.

DUse fluids and solvents which are compatible with the equipment wetted parts. Refer to the Tech-

nical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.

DHandle hoses carefully. Do not pull on hoses to move equipment.

DRoute hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose

Graco hoses to temperatures above 66_C (150_F) or below –40_C (–40_F).

3082244

WARNING

INJECTION HAZARD

Spray from the valve, leaks or ruptured components can inject fluid into your body and cause ex-

tremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can

also cause serious injury.

DFluid injected into the skin is a serious injury. The injury may look like just a cut, but it is a serious

injury. Get immediate medical attention.

DDo not point the valve at anyone or at any part of the body.

DDo not put your hand or fingers over the valve tip.

DDo not stop or deflect leaks with your hand, body, glove or rag.

DDo not “blow back” fluid; this is not an air spray system.

DAlways have the tip guard and the trigger guard on the valve when spraying.

DBe sure the valve trigger safety operates before dispensing.

DLock the valve trigger safety when you stop dispensing.

DFollow the Pressure Relief Procedure on page 21 if the spray tip clogs and before cleaning,

checking or servicing the equipment.

DTighten all fluid connections before operating the equipment.

DCheck the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.

Permanently coupled hoses cannot be repaired; replace the entire hose.

MOVING PARTS HAZARD

Moving parts, such as the air motor piston, can pinch or amputate your fingers.

DKeep clear of all moving parts when starting or operating the pump.

DKeep hands and fingers away from the piston during operation and whenever the pump is charged

with air.

DBefore checking or servicing the equipment, follow the Pressure Relief Procedure on page 21 to

prevent the equipment from starting unexpectedly.

308224 5

WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and re-

sult in a fire or explosion and serious injury.

DGround the equipment and the object being sprayed. Refer to Ground the Pumps on page 10.

DIf there is any static sparking or you feel an electric shock while using this equipment, stop spray-

ing immediately. Do not use the equipment until you identify and correct the problem.

DProvide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid

being sprayed.

DKeep the spray area free of debris, including solvent, rags, and gasoline.

DBefore operating this equipment, electrically disconnect all equipment in the spray area.

DBefore operating this equipment, extinguish all open flames or pilot lights in the spray area.

DDo not smoke in the spray area.

DDo not turn on or off any light switch in the spray area while spraying or while operating if fumes

are present.

DDo not operate a gasoline engine in the spray area.

TOXIC FLUID HAZARD

Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin,

inhaled, or swallowed.

DKnow the specific hazards of the fluid you are using.

DStore hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,

state and national guidelines.

DAlways wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and

solvent manufacturer.

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.

Typical Installation

About the Typical Installations

These pumps are designed to be part of a Hydra-Cat

dispensing system that will proportion, mix, and

dispense two-component fluids. The typical installa-

tions shown below and on page 9 are only guidelines

to setting up a complete proportioning system. For

clarity, various components are shown in the correct

order but may not be shown in exactly the position of

the installed system. For assistance in designing your

system, contact your Graco distributor.

NOTE: When pressure feeding the proportioning

pump, mount fluid pressure gauges (J) at the propor-

tioning pump inlets to monitor proper adjustment of the

feed pump pressures. Never exceed 25% of the

Hydra-Cat pump outbound fluid pressure on the feed

supply.

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.
