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.

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.
3A1938E 9
Installation
Flush Connections
Line flushing connections are recommended when
pumping slurries or liquids with a high concentration
of solids that tend to settle when the pump is turned
off.
NOTE: Accumulation of solids in the hose after
shutdown can reduce hose life because the hose will
experience high stress when restarting the pump.
Pulsation Dampeners
Hose pumps sometimes require the use of pulsation
dampeners on either the inlet or outlet to increase
the hose life during operation. A pulsation dampener
acts to absorb the energy of the pulsations that the
pump produces so that these forces do not act upon
the hose. Your Graco distributor will assist you in
selecting the proper size and application of these
devices in your system.
If your operation does require pulsation dampeners,
mount them as close to the inlet and/or outlet of the
pump as possible. Do not support the weight of the
dampeners on the pump connections. These devices
must be independently supported.
Outlet pulsation dampeners work best when there
is some back pressure in the outlet line. Pulsation
dampeners do not work efficiently at low outlet
pressures or when the pump discharges directly to
the atmosphere.
Drain and Vent Plugs
The pump is equipped with a low point drain (17)
and a vent (15). The drain is typically plugged with a
stainless steel plug, and the vent prevents a buildup
of excess pressure in the pump housing.
Lubricate the Pump
Before operating the pump, add hose lube to the
pump housing as explained below. Failure to do
so will result in reduced hose life. The hose lube
acts as a lubricant between the hose and the roller
and between the roller and the eccentric shaft.
It also dissipates heat from the hose. Check the
compatibility of the hose lube with your pumped fluid.
1. Disconnect the pump from the power source.
2. Remove the screws holding the motor fan cover.
Turn the fan by hand until the roller stops at the
bottom of the pump housing in the 6 o’clock
position.
NOTE: Therollermustbeinthe6o’clockposition
to prevent overfilling the pump with hose lube.
3. Unscrew the vent plug (15) near the top of the
cover.
4. Using a funnel, add hose lube through the vent
port. For EP3 and EP4 Models, the oil will be
visible through the sightglass (16). The oil level
must not rise above the halfway point on the
roller.
NOTE: Do not overfill. Overfilling the pump
housing with hose lube will increase pressure
inthepumphousing,causinghoselubetoleak
from the cover or the clamp area. See the table
below for the correct amount of hose lube for
your pump. Pre-measuring the correct amount
will help prevent overfilling.
Pump Model
EP2006, EP2013
EP3019
EP4029
NOTE: Higher operating speeds provide more
vigorous lubrication, which may cause splashing
of oil. When operating at a speed of 85 RPM
or greater, reduce the amount of hose lube as
shown in the table below.

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.
1. Pump: The pump is grounded through
a proper electrical connection. See
Main Power Connections at the VFD, page 14.
2. Fluid hoses: 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.

NOTICE
Never operate the pump if the fluid inside the hose
is frozen. This will cause serious damage to the
pump.
If operating the pump at low temperatures, ensure
that the fluid being pumped does not freeze inside
the hose, especially during long periods of idleness.
Do not start the pump if the fluid inside the hose is
frozen. Ensure that the inlet line, the outlet line, and
the pump housing are heat-taped and insulated so
freezing does not occur.

1. Remove the front cover drain plug to drain all
lubricant from the pump. Once the pump is
drained of lubricant, add a desiccant pack to
prevent moisture accumulation. Leave the drain
plug out until restoring the pump to service, to
prevent water from accumulating in the pump.
2. Remove the hose from the pump. See the Pump
Repair-Parts Manual.
3. Grease the bearings as needed.
4. Inspect the pump and re-crate it. Store the pump
in a clean, dry area that is free from extremes in
temperature.

Maintenance
Maintenance
Maintenance and repair of the pump involves
potentially hazardous procedures. Only trained
and qualified personnel who have read and who
understand the instructions in this manual should
maintain or repair this equipment.
Preventive Maintenance Schedule
Check the following items at the intervals listed below,
following all of the safety warnings in this manual.
Every Three Months
Check gauges on pump inlet and outlet and pump
operating speed to confirm operating point.
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.
Pump Bearing Lubrication
Grease-lubricated pump bearings require an NLGI
Number 2 grease such as Shell Dolium R or
equivalent. Grease the bearings every 24 months,
depending on duty cycle and ambient conditions.
1. Remove the plug (18) from the pump housing
and replace it with a zerk fitting.
2. Use a low pressure grease gun to pump grease
into the zerk fitting. Add grease until it passes
through the outer bearing of the shaft.
Every Six Months
• Check bearing temperature and compare with
earlier readings.
• Run an amperage reading to verify that the motor
is running normally.
• Inspect the fan guard and remove any accumulated
debris from under it and around the motor.
• Tighten any fasteners that may be loose.
• Lubricate the motor. See the motor manufacturer’s
instructions.
• Lubricate the pump. See
Pump Bearing Lubrication, page 20, and
Hose Lubrication, page 20.
3. Remove the zerk fitting and reinstall the plug (18).
Inspect the pump and re-grease the bearings if you
suspect that the original grease was contaminated
by a grease seal failure.
Hose Lubrication
The pump requires lubrication of the hose. The
lubrication provides longer hose life by increasing
cooling and reducing friction between the roller and
the hose. The use of non-standard lubricant can
impact your hose life; always use genuine Graco
hose lube.
Fill your pump to the level indicated in
Lubricate the Pump, page 10.
