See FIG. 2. page 6.
Maximum Working Pressure of Accessories
Limit Fluid Flow to Reciprocator
To reduce the risk of serious injury including fluid injec-
tion and splashing in the eyes or on the skin which may
be caused if component ruptures, all accessories
added to the reciprocator power supply side must have
at least 600 psi (4.1 MPa, 41 bar) maximum working
pressure.
To reduce the risk of overpressurizing the hydraulic
reciprocator which could cause a rupture and serious
injury, including fluid injection, a hydraulic system must
have a means to limit the incoming fluid flow to the
reciprocator to a maximum of 3 gpm (11 lpm) and 600
psi (4.1 MPa, 41 bar). See description below.
All accessories added to the pump fluid outlet side
must have at least 7500 psi (51 MPa, 517 bar) maxi-
mum working pressure.
The hydraulic power supply system (U) must have a
pressure reducing valve and a pressure-compensated
flow control. A flow control valve (Q) is required to limit
the incoming flow to the reciprocator to a maximum of 3
gpm (11 lpm).
Pump Accessories
NOTE: The reference letters in the following descrip-
tions, refer to the reference letters used in FIG. 2, page
6.
Hydraulic Lines
Shut-off Valves (H, L): Installed on the hydraulic supply
and return lines. Order Part No. 108537 and 112578.
Follower Plate (A): Place follower plate on grease and
rotate while pressing firmly to level material. Order part
number 247700 for 60# and 90# automatic lube pump
modules; 247701 for 120# refinery reservoir; or 247702
for 400# refinery reservoir.
Drain Line: Monitor the weepage of hydraulic fluid or
lubricant. If it seems excessive or increases suddenly,
the reciprocator/pump seals may need to be changed.
Pump Outlet Drain Valve (D): Helps relieve fluid pres-
sure in pump when pump is shut off. Install valve close
to pump fluid outlet. Order valve, Part No. 111229.
Hoses: Use a minimum 1/2 inch supply line (R) and
minimum 3/4 inch return line (F) on the reciprocator.
Contact your Graco representative for line sizing.
A pump outlet drain (D) is required in your system. This
valve helps relieve pressure in the displacement pump
and hose when shutting down system and in case of a
clogged outlet hose. Install valve close to pump outlet.
Pressure Reducing Valve (N): Circulates excess
hydraulic fluid pressure back to the hydraulic power sup-
ply. Install this valve (N) in the hydraulic supply line with
a drain hose (W) teed into the hydraulic return line (F).
Limit supply pressure to a maximum 600 psi (4.1 MPa,
41 bar).
Accumulator (P): Reduces hammering effect caused
by the motor when it reverses direction.
Fluid-filled Pressure Gauge (M), Part No. 112567:
Monitors hydraulic pressure to the reciprocator during
startup. See FIG. 2. Use the gauge for initial adjustment
of the reciprocator. It can be removed after adjustment.
NOTE: Pressure gauge (M), pressure reducing valve
(N) and a flow control valve (Q) are included in the
Hydraulic Fluid Control Kit 247538 or 247705, which can
be ordered separately.

Installation
Grounding
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
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.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
•
Pump: Order Grounding Wire and Clamp Kit,
Part No. 222011. See Grounding the Pump and
•
•
•
Hydraulic Hoses and Fluid Outlet Hoses:
Use electrically conductive hoses only.
The system pressure must be manually relieved to pre-
vent the system from starting or dispensing accidentally.
Hydraulic Power Supply: Follow manufac-
turer’s recommendations.
For the following instructions, see FIG. 2.
1. Shut off hydraulic power supply.
Flushing Pails: When flushing, only use metal,
grounded pails. Make firm, metal-to-metal con-
tact between the metal part of the dispense
valve and the pail. Use lowest possible pres-
sure.
2. Close supply line shut-off valve (L).
3. Open dispensing valve to relieve pressure.
4. Open pump outlet drain valve. Have a container
ready to catch drainage.
Grounding the Pump
5. Close return line shut-off valve (H).
6. If you suspect the nozzle or hose is completely
clogged or that pressure has not been fully relieved
after following steps 1-5 above, very slowly loosen
the hose end coupling to relieve pressure, then
clear obstruction.
1. Remove ground screw (Z) and insert through eye of
ring terminal at end of ground wire.
2. Fasten ground screw back onto pump and tighten
securely.
3. Connect other end of wire to a true earth ground.
NOTE: Keep drain valve open until you are ready to dis-
pense again.

Operation
Operation
Starting Pump
NOTICE
To prevent damage to pump, do not operate pump
without it being securely mounted to a drum cover or
support.
For the following instructions, see FIG. 2.
1. Turn on hydraulic power supply.
2. Open return line shut-off valve (H) first, then slowly
open the hydraulic supply shut-off valve (L).
3. Adjust flow control valve (Q) to limit the hydraulic
flow to no more than 3 gpm (11 lpm), which is
approximately 60 cycles per minute.
COMPONENT RUPTURE HAZARD
4. Adjust pressure reducing valve (N) to increase
hydraulic inlet pressure from 50 to 600 psi (0.34 to
4.1 MPa, 3.4 to 41 bar).
Overpressurizing any component can result in serious
injury or property damage as a result of rupture, fire, and/or
explosion.The maximum working pressure of each
component in the system may not be the same. To reduce
the risk of overpressurizing any component in the system:
•
Increasing inlet pressure, increases outlet pres-
sure.
• Be sure you know the maximum working pressure of
each component.
•
Decreasing inlet pressure, decreases outlet
pressure.
• Never exceed the maximum working pressure of the
5. Open drain valve while priming pump.
6. When pump is primed, close drain valve.
lowest rated component in the system.
• Do not exceed the maximum pump cycle rate.
• The pump has a rated ratio of 10:1. However, it is
capable of reaching stall pressures equal to 12.5 times
the hydraulic input pressure. To calculate the fluid
output pressure, multiply the hydraulic pressure shown
on the hydraulic control module gauge by 12.5.
NOTICE
Always use lowest pressure possible to obtain desired
results. This reduces pump wear.
For example:
600 psi hydraulic x 12.5 = 7500 psi fluid output
4.14 MPa hydraulic x 12.5 = 51.8 MPa fluid
output
Maximum Working Pressures
To reduce the risk of serious injury, including fluid injection
and splashing in the eyes or on the skin, which may be
caused if a component ruptures:
41.4 bar hydraulic x 12.5 = 5.18 bar fluid output
• Regulate hydraulic pressure to the pump so that no
fluid line component or accessory is overpressurized.
• Never exceed 600 psi (4.1 MPa, 41 bar) Maximum
Hydraulic Pressure to the reciprocator.
• Never exceed 7500 psi (51 MPa, 517 bar) Maximum
Outlet Pressure from the displacement pump.
Before Starting Pump
•
Check hydraulic fluid level in hydraulic power supply
before each use. Add fluid as necessary to fill the
lines.
• Accessories added to the pump fluid outlet side should
have at least a 7500 psi (51 MPa, 517 bar) Maximum
Working Pressure.
• Read and understand COMPONENT RUPTURE
HAZARD instructions, page 7.
•
Flush pump before using it for the first time to
remove the light oil that was left in after factory test-
ing to protect pump from corrosion. Be sure solvent
used is compatible with the fluid to be pumped and
the pump’s wetted parts. See Technical Data, page
26. Flush until clean solvent comes out of hose.
