Installation
Installation
Installation of your pump involves potentially
hazardous procedures. Only trained and qualified
personnel who have read and who understand
the information in this manual should install this
equipment.
Receiving and Handling
Upon receipt of your pump:
• Carefully inspect the pump to verify that no damage
occurred during transit. Check the packing list to
ensure that all parts and accessories are present.
NOTE: If you find any damage or shortage,
immediately notify your Graco distributor.
• Refer to the pump identification plate (ID) for the
pump part number and series level.
• Leave the pump assembly crated, horizontal, and
stored in a warm, dry location until you are ready
to install it. To store the pump more than 30 days,
see Storage, page 19.
Moving the Pump
The pump is heavy. Handle it carefully. Careless
handling can result in equipment damage and
injury to personnel.
After you receive and inspect your pump, transfer it
to the assembly location or storage area.
NOTE: To prevent hose damage if storing the pump
more than 30 days, see Storage, page 19.
Use the proper forklift truck for lifting equipment
on pallets or in crates. The lift forks should extend
under the equipment and completely support the
unit. When necessary to lift by crane, use the vertical
points of the equipment or the crating for pickup so
the equipment remains level. Use long lift cables,
chains, or straps, as required, to evenly support
the equipment. In addition, use a spreader bar, if
necessary, to ensure a vertical pull at all lift points.
Short cables or chains can create a cross shear that
can damage the equipment.
NOTICE
If your pump is supplied with a gear motor, lift only
with straps located under the gear motor and under
the front of the pump.

Installation
Location
Allow sufficient space to permit easy access for
maintenance and service, especially in front of
the pump. The pump area should have adequate
headroom and sufficient ventilation.
Before installing your pump, see
Dimensions, page 21, to ensure that the
available space is sufficient for the pump, taking into
account the following provisions:
• Dimension and weight of the pump package.
• Required moving and hoisting equipment.
• Possible piping layout, including space for removal
and maintenance.
• Freedom of movement to operate the unit,
read speed and pressure gauges, and provide
adjustment and maintenance.
• Space required for lubrication.
• Space for removal of the hose from the unit.
• Location of the nearest drain or catch basin to
collect used lubricant and fluid.

NOTE: The hose is serviced through the front cover.
Therefore, provide sufficient work space in front of
the pump when installing the unit.
Mount the Pump
See Mounting Hole Layouts, page 22.
Mount the pump on a flat concrete foundation 4
inches (100 mm) wider and longer than the pump
base. When installing the pump, make sure that the
surface of the foundation is smooth and free of debris.
The foundation should be level and of sufficient depth
and strength to adequately support the pump.
Anchor bolts should be set into the concrete
foundation. For best results, use anchor bolts made
of corrosion resistant material such as stainless
steel. Anchor bolt nuts should be of a different grade
stainless steel to prevent galling. Level the pump as
required, using shims.
Initially tighten the anchor bolts one eighth of a turn
with a wrench. Do not fully tighten until after all piping
has been connected.

Installation
Fluid Connect
Undue stress on the pump inlet or outlet
connections can cause serious injury or equipment
failure. The fluid inlet and outlet lines must be
independently supported. The pipe supports
should be located as close to the pump as possible.
NOTE: The hose connections require the use of a
hose clamp. Part No. 24L497 Clamping Tool is
available from Graco.

NOTICE
Install a pressure relief valve upstream of a
shutoff valve at the pump outlet, to prevent
over-pressurization that can damage the pump or
the hose.
NOTE: If your installation requires the fluid inlet
and outlet positions to be reversed, this can
be done by reversing the motor rotation. See
Reverse Motor Direction, page 17.
Fluid Inlet Line
Locate the pump as close to the fluid source as
possible. The inlet piping should be at least the
same diameter as the pump inlet connection and
should have a straight run of pipe that is a minimum
of 8 to 10 pipe diameters long. Inlet piping must be
airtight and suitable for both pressure and vacuum.
If possible, provide a larger diameter pipe than the
pump inlet connection.
Install the pressure relief valve near the pump outlet.
Downstream of the pressure relief valve, install
a shutoff valve to isolate the unit for service and
repair. Install a pressure gauge to monitor pump
performance. A check valve is not recommended
on the outlet of the pump since the pump acts as its
own check valve.
