Installation
Grounding
This equipment must be grounded to reduce the
risk of static sparking and electric shock. Electric
or static sparking can cause fumes to ignite or
explode. Improper grounding can cause electric
shock. Grounding provides an escape wire for the
electric current.
Pump:
1.
See Fig. 4. Loosen the ground screw and

securely. Connect the other end of the ground
wire to a true earth ground.
Fluid hoses:
2.
3.
Use only electrically conductive
hoses with a maximum of 500 ft. (150 m)
combined hose length to ensure grounding
continuity. Check the electrical resistance of
hoses. If total resistance to ground exceeds 25
megohms, replace hose immediately
NOTE:
Advanced models require installation
of the 24P822 Control Module. All pumps
connected to a common control module must be
grounded to the same ground point. Different
ground points (unequal potential) may cause
current to flow through component cables,
causing incorrect signals.
Fluid supply container:
Follow your local code.

Fluid Line Accessories
Install the following accessories in the order shown
in Fig. 1, using adapters as necessary. All fluid
lines and accessories must be rated to the maximum
working pressure of 400 psi (2.8 MPa, 28.0 bar).

Fill With Oil Before Using Equipment
See Fig. 5. Before using the equipment, open the fill
cap (P) and add Graco Part No. 16W645 ISO 220
silicone-free synthetic gear oil. Check the oil level in
the sight glass (K). Fill until the oil level is near the
halfway point of the sight glass. The oil capacity is

approximately 1.5 quarts (1.4 liters).
NOTE:
Two 1 quart (0.95 liter) bottles of oil are
supplied with the equipment.
Control Module Accessory

Operation
Operation
Startup
Pressure Relief Procedure
To operate the pump, follow the Startup instructions
for the Basic or Advanced motor in the Motor manual.
The Advanced E-Flo DC motors require installation of
the 24P822 Control Module Accessory Kit to provide
the interface for users to enter selections and view
information related to setup and operation. See the
Control Module Accessory Kit manual for installation
and operation information.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from splashing fluid and moving parts, follow the
Pressure Relief Procedure when you stop spraying
and before cleaning, checking, or servicing the
equipment.
Run the pump at a slow speed until the fluid lines are
primed and all air is forced out of the system.
Shutdown
1. Disengage the start/stop control (C). See Fig. 1.
2. Shut off and lock out the fused safety switch (B).
3. Open the fluid drain valve (D), having a waste
container ready to catch drainage. Leave open
until you are ready to pressurize system again.

Maintenance
Maintenance
Preventive Maintenance Schedule
Check Oil Level
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.
See Fig. 7. Check the oil level in the sight glass (K).
The oil level should be near the halfway point of the
sight glass when the unit is not running. If low, open
the fill cap (P) and add Graco Part No. 16W645 ISO
220 silicone-free synthetic gear oil as required. The
oil capacity is approximately 1.5 quarts (1.4 liters).
Do not overfill.
Change the Oil
NOTE:
Change the oil after a break-in period of
200,000–300,000 cycles. After the break-in period,
change the oil once a year.
1. See Fig. 6. Place a minimum 2 quart (1.9 liter)
container under the oil drain port. Remove the
oil drain plug (25). Allow all oil to drain from the
motor.
2. Reinstall the oil drain plug (25). Torque to 25–30
ft-lb (34–40 N•m).
3. See Fig. 7. Open the fill cap (P) and add Graco
Part No. 16W645 ISO 220 silicone-free synthetic
gear oil. Check the oil level in the sight glass (K).
Fill until the oil level is near the halfway point of
the sight glass. The oil capacity is approximately

1.5 quarts (1.4 liters).
4. Reinstall the fill cap.
Bearing Pre-Load
See Fig. 7. The bearing pre-loads (R) are factory
set and are not user adjustable. Do not adjust the
bearing pre-loads.
Flushing
• Flush before changing fluids, before fluid can dry
in the equipment, at the end of the day, before
storing, and before repairing equipment.
• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.

Performance Charts
Key to Performance Charts
To find the fluid pressure (psi/bar/MPa) at a specific
fluid flow (gpm/lpm) and percentage of maximum
force:
NOTE:
The charts show the motor operating at
100%, 70%, and 40% of maximum force. These
values are approximately equivalent to an air motor
operating at 100, 70, and 40 psi.
1. Locate the desired fluid flow in the scale at the
bottom of the chart.
2. Follow the vertical line up to the intersection with
the selected percentage of maximum force (see
100% of maximum force
70% of maximum force
40% of maximum force

below).
3. Follow left to the vertical scale to read the fluid
outlet pressure.
