Warnings
63A6349A
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-
tion point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When
these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific
hazard symbols and warnings not covered in this section may appear throughout the body of this manual where
applicable.
FIRE AND EXPLOSION HAZARD
When flammable fluids are present in the work area be aware that flammable fumes can ignite or
explode. To help prevent fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources, such as cigarettes and portable electric lamps.
• Ground all equipment in the work area.
• Keep work area free of debris, including rags and spilled or open containers of solvent.
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Use only grounded hoses.
•Stopoperationimmediatelyifstaticsparkingoccurs oryoufeel ashock.Do not use equipmentuntil
you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
SKIN INJECTION HAZARD
High-pressure fluid from dispensing device, hose leaks, or ruptured components will pierce skin. This
may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical
treatment.
• Do not put your hand over the fluid outlet.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or
servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses and couplings daily. Replace worn or damaged parts immediately.
MOVING PARTS HAZARD
Moving parts can pinch, cut or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,
follow the Pressure Relief Procedure and disconnect all power sources.

Warnings
3A6349A 7
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.
• Read Safety Data Sheet (SDS) to know the specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including
eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment includes but is not
limited to:
• Protective eyewear, and hearing protection.
• Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system com-
ponent. See Technical Specifications in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Specifica-
tions in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete infor-
mation about your material, request Safety Data Sheets (SDSs) from distributor or retailer.
• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.
• Checkequipmentregularly.Repairorreplacewornordamagedpartsimmediatelywith genuineman-
ufacturer’s replacement parts only.
• Do not alter or modifyequipment. Alterations or modifications may void agency approvals and create
safety hazards.
• Make sure all equipment is rated and approved for the environment in which you are using it.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.

Installation
83A6349A
Installation
Grounding
Pump: grounded through fluid lines.
Fluid lines: use only electrically conductive lines.
Fluid supply container: follow local code.
Accessories
Install the following required accessories in the order
shown in a typical installation (see FIG. 3 on page 9)
using adapters as necessary.
•Fluid filter (Y-Strainer) (included in K): with a 60
mesh (250 micron) stainless steel element to filter
particles from the fluid before in reaches the pump.
•Fluid shutoff valves (L): shuts off fluid flow.
•Pressure relief valve (D): overload protection.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid con-
taminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
Flush the Equipment, page 12.
Typical Installation
FIG. 3 is an example of an installation with a G-Chem
chemical injection beam pump. Your installation may dif-
fer from what is shown here. (See Accessories on
page 8.) The G-Chem beam pump (A) and the swivel
block (B) are the only components in FIG. 3 supplied by
Graco. All other components are supplied by customer.

M Pumpjack Base (I-Beam)
N Cable/Rod/Pipe
P Walking Beam
R Beam Clamp
To avoid injury due to unexpected moving parts,
remove power to the pumpjack and wait for the walk-
ing beam to stop moving before performing any task
on the G-Chem pump. The G-Chem pump is directly
influenced by the motion of the pumpjack’s walking
beam, and the pump is inactive only when the walking
beam is unable to move.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.

Pumpjack Connections
1. Remove power to the pumpjack and wait for the
pumpjack to stop moving.
2. Attach a cable (N) to the walking beam (P) using a
beam clamp (R) or other connection method (both
user-supplied).
• Place the beam clamp (R) on the walking beam
(P) where the vertical travel is, at most, 21 in.
(53.34 cm), which is the maximum travel of the
G-Chem pump’s lever arm.
3. Position the G-Chem pump (A) on the pumpjack
base (M) so that the walking beam (P) provides a
straight upward pull as it rises.
• The lever arm (122) must be able to travel 6 in.
below the base of the G-Chem pump (A) to
achieve maximum flow.
4. Securely clamp or bolt the G-Chem pump (A) to the
pumpjack base (M) using the pump’s supplied
base (112).
• The G-Chem pump (A) is shipped with the sup-
plied base (112) already attached.
5. Connect the lever arm (122) to the walking beam
(P) by routing the end of the cable (N) through the
eye bolt (8) on the supplied swivel block (B).
6. Ensure there is no slack in the cable (R) when the
G-Chem pump (A) is maximum stroke (setting “1”
on the lever arm (122) and “Full” on the stroke
adjust). Refer to Adjust the Pump Stroke on
page 14.
