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 F
IG
. 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
F
IG
. 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 F
IG
. 3 supplied by
Graco. All other components are supplied by customer.

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.
