Installation
The pump is designed to supply hydraulic oil to the
accumulators in an oil rig blow-out prevention system.
The Typical Installation shown in FIG. 1, page 4 is only a
guide. Contact your Graco representative for assistance
in designing a system to meet your needs.
Mount the pump to suit your type of installation. The
Dimension Drawing on page 18 gives measurements
needed for installing the pump.
Reference numbers and letter in the text refer to the call-
out on the drawings.
Grounding
The following instructions refer to FIG. 2.
To ground the pump:
1. Loosen the grounding lug locknut (N) and washer
(P).
2. Insert one end of a 12 gauge (1.5 mm2) minimum
ground wire (R) into the slot in lug (S) and tighten
the locknut securely.
3. Connect the other end of the wire to a true earth
ground such as a steel building column or water
pipe. Check local code.
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.
• Proper hose and plumbing line grounding
continuity is essential to maintaining a grounded
system. Check the electrical resistance of your air
and fluid hoses or plumbing line at least once a
week.
• If you hose does not have a tag on it which
specifies the maximum electrical resistance,
contact the hose supplier or manufacturer for the
maximum resistance limits.
• Use a resistance meter in the appropriate range
for your hose to check the resistance. If the
resistance exceeds the recommended limits,
replace it immediately.
• An ungrounded or poorly grounded hose or
plumbing line can make your system hazardous.

System Accessories
The following instructions refer Typical Installation, FIG.
1, page 4.
Install the following accessories in the order shown in
Typical Installation (FIG. 1) using adapters as necessary.
To ensure maximum pump performance, be sure that
any accessory used is properly sized to meet your sys-
tem requirements.
•A bleed-type master air valve (C) and Fluid Drain
Valve (M) are required in your system to reduce the
risk of serious bodily injury from moving parts, injec-
tion or splashing in the eyes or on the skin when
shutting of the pump. The bleed-type master air
valve relieves air trapped between the air valve and
pump, after the pump is shut off. Trapped air can
cause the pump to cycle unexpectedly, which could
result in serious injury from splashing or moving
parts. Be sure the valve is easily accessible from the
pump and located downstream from the air regula-
tor.
• On the air line (A) install an air regulator (D) near
the pump air inlet (E) to control pump speed and
outlet pressure and an air line oiler (C) down-
stream from the regulator to provide automatic lubri-
cation to the air motor.
• Use an adequately sized air regulator to control
pump speed and fluid pressure.
• Upstream form the oiler, install an air filter (F) to
remove harmful dirt and moisture from the com-
pressed air supply.
Hose and Plumbing Lines
The following instructions refer to Typical Installation,
FIG. 1, page 4.
In this system, fluid and air lines may be either hoses or
hard plumbed. All lines must be grounded (see Ground-
ing, page 5).
•ALL FLUID HOSES MUST HAVE SPRING
GUARDS! The spring guards help protect the hose
from kinks or bends at or close to the coupling which
can result in hose rupture.
• Tighten all fluid connections securely before each
use. High pressure fluid can dislodge a loose cou-
pling or allow high pressure spray to be emitted from
the coupling.
• Never us a damaged hose or plumbing component.
Before each use, check the entire hose or plumbing
line for cuts, leaks, abrasion, bulging cover, damage
or movement of couplings. If any of these conditions
exist, replace the hose or defective components
immediately. DO NOT try to recouple high pressure
hoses or mend it with a tape or any other device. A
repaired hose cannot contain the high pressure
fluid.
Connecting Lines
1. Connect the air supply (A) to the 3/4 npsm(f) air
inlet (F).
2. Connect the fluid supply line (K) to the 1 inch
npt(f) fluid intake (J) and the fluid line (H) to the
3/4 npt(f) fluid outlet (G).
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.

Operation
307714E 7
Operation
Starting and Adjusting the Pump
1. Open the fluid supply shut off valve and the system
drain valve.
2. Open the bleed-type master air valve (C).
3. Slowly open the air regulator (D) until the pump
starts to cycle - about 40 psi (2.8 bar, 0.28 MPa).
4. Allow pump to cycle slowly until all air is purged
from the lines.
NOTE: The lines are purged when the fluid emitted
from the drain valve is flowing in a steady stream.
5. With the lines purged, close the system drain valve
(M).
NOTE: The pump will stall against pressure.
• With the pump and lines primed and with adequate
air pressure and volume supplied, the pump will
start and stop as supply demands or until the
bleed-type master air valve (C) is shut off.
• If your pump accelerates quickly, or is running too
fast, stop it immediately and check the fluid supply. If
the supply container is empty and air has been
pumped into the lines, prime the pump and lines
with fluid or flush and leave filled with compatible
solvent.
• Be sure to eliminate all air from fluid system to pre-
vent corrosion.
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Shut off air to the pump.
2. Close the bleed-type master air valve.
3. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Keep you
hands away from the end of any drain valve when
opening it.
4. Leave drain valve(s) open until you are ready to
pump again.
5. If you suspect the hose is clogged or plumbing line
is clogged or that pressure has not been fully
relieved after following the steps above, VERY
SLOWLY loosen the hose or line end coupling to
relieve pressure gradually, then loosen completely.
Clear the obstruction.
Never exceed 100 psi (7 bar, 0.7 MPa) air input
pressure to the pump, to reduce the risk of
component rupture which can cause serious bodily
injury, including injection or splashing of fluids in the
eyes or on the skin and to avoid damage to the pump.
NOTICE
Always use the lowest air pressure necessary to give
you the result you want. Higher pressure causes pre-
mature pump wear.
NOTICE
Never allow the pump to run dry of fluid being pumped.
A dry pump will quickly accelerate to a high speed, pos-
sibly damaging itself.
NOTICE
Water or even moist air can cause pump corrosion. To
prevent corrosion, NEVER leave the pump filled with
water or air. After normal flushing, flush the pump again
with water or mineral spirits or oil-based solvent,
relieve pressure (see Pressure Relief Procedure,
below) and leave the mineral spirits in the pump.
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 pumping and before
cleaning, checking, or servicing the equipment.

Maintenance and Repair
Throat Packing Nut
1. Relieve pressure following pressure relief proce-
dure (page 7).
2. Check tightness of throat packing nut, weekly. The
nut should be tight enough to prevent leakage - no
tighter.
Locating Air Leaks
Air leaks can generally be detected by listening when
the pump is not running. To locate where the air is leak-
ing:
1. Turn off air supply.
2. Relieve pressure, page 7.
3. Disconnect the air hose.
4. Screw the inlet union (117) out of the manifold (87).
5. Remove the air motor shield (73) and screw the inlet
union (117) back into the manifold (87).
6. Connect the air hose and turn the air on. DO NOT
EXCEED 40 psi (2.8 bar, 0.28 MPa) inbound pres-
sure.
7. Use the checking methods listed in the Air Leak
Check Chart to find where the air is leaking.
Replace parts as necessary.
Air Leak Check Chart
