Genera Information
The Typical Installation shown is only a guide
for selecting and installing system components.
ontact your Graco distributor for assistance in
planning a system to suit your needs. Always use
Genuine Graco Parts and Accessories. Be sure all
accessories are adequately sized and pressure rated
to meet the system’s requirements.
Reference letters in the text, for example (A), refer to
thecalloutsinthefigures.
OTE: For outdoor applications, be sure to provide
adequate protection from the elements.
Tighten Fasteners
Before mounting and using the pump for the first time,
check and retorque all external fasteners. Follow
Torque Instructions, page 49, or see the torque
tag on your pump. After the first day of operation,
retorque the fasteners.
Tips to Reduce Cavitation
avitation in a double diaphragm pump is the
formation and collapse of bubbles in the pumped
liquid. Frequent or excessive cavitation can cause
serious damage, including pitting and early wear of
fluid chambers, balls, and seats. It may result in
reduced efficiency of the pump. avitation damage
and reduced efficiency both result in increased
operating costs.
avitation depends on the vapor pressure of the
pumped liquid, the system suction pressure, and the
velocity pressure. It can be reduced by changing any
of these factors.
1. Reduce vapor pressure: Decrease the
temperature of the pumped liquid.
2. Increase suction pressure:
a. Lower the installed position of the pump
relative to the liquid level in the supply.
b. Reduce the friction length of the suction
piping. Remember that fittings add friction
length to the piping. Reduce the number of
fittings to reduce the friction length.
c. Increase the size of the suction piping.
d. Increase the Net Positive Suction
Head Available (NPSHa). See
Performance harts, page 50.
OTE: Be sure the inlet fluid pressure does not
exceed 25% of the outlet working pressure.
3. Reduce liquid velocity: Slow the cyclic rate of
the pump.
Pumped liquid viscosity is also very important but
normally is controlled by factors that are process
dependent and cannot be changed to reduce
cavitation. Viscous liquids are more difficult to pump
and more prone to cavitation.
Graco recommends taking all of the above factors
into account in system design. To maintain pump
efficiency, supply only enough power to the pump to
achieve the required flow.
Graco distributors can supply site specific
suggestions to improve pump performance and
reduce operating costs.

Mount the Pump
To avoid serious injury or death from toxic fluid or
fumes:
• Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always
follow the Pressure Relief Procedure, page 29,
before moving or lifting the pump.
NOTICE
The pump is heavy. To prevent damage from
dropping, always use 2 people or a lift to move the
pump. Do not use the manifolds to lift the pump.
Use at least one strap.
1. For all mountings, be sure the pump is secured
with screws through the mounting feet (D) and
through the mounting bracket on the gear box.
See Dimensions, page 56.
NOTICE
To prevent pump damage, use all eight
fasteners.
2. Make sure the surface is flat and that the pump
doesn’t wobble.
3. For BLD models, securely mount the Graco
Motor ontrol using the provided mounting tabs.
4. For ease of operation and service, mount the
pump so fluid inlet and fluid outlet ports are easily
accessible.
5. Prolonged exposure to UV radiation will degrade
natural polypropylene components of the pumps.
To prevent potential injury or equipment damage,
do not expose pump or the plastic components
to direct sunlight for prolonged periods.
6. Cart Mounting: Some models can be ordered
mounted on a cart. For all other models, art

Installation
Grounding
The 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.
• Always ground the entire fluid system as
described below.
• Pumps with Polypropylene and PVDF fluid
sections are
not conductive. ever use a
nonconductive polypropylene or PVDF pump
with flammable fluids.
• Follow your local fire codes.
Before operating the pump, ground the system as
explained below.
• Pump: Pumps with fluid sections made of
aluminum, conductive polypropylene, hastelloy,
and stainless steel have a ground screw. Loosen
the grounding screw (R). Insert one end of a
12–gauge minimum ground wire behind the ground
screw and tighten the screw securely. onnect the
clamp end of the grounding wire to a true earth
ground. A ground wire and clamp, Part 238909,
is available from Graco.
• Motor: A and BLD motors have a ground screw
in the electrical box. Use it to ground the motor to
the controller.
• Air Line and Fluid hoses: Use only grounded
hoses with a maximum of 500 ft (150 m) combined
hose length to ensure grounding continuity. heck
electrical resistance of hoses. If total resistance
to ground exceeds 29 megohms, replace hose
immediately.
• Fluid supply container: Follow local code.
• Solvent pails used when flushing: Follow local
code. Use only conductive metal pails, placed
onagroundedsurface. Donotplacethepail
on a nonconductive surface, such as paper or
cardboard, which interrupts grounding continuity.
• VFD: Ground the variable frequency drive (VFD)
through a proper connection to the electrical
system. Refer to the VFD manual for grounding
instructions.
• Graco Motor Control: Ground through a
proper connection to a power source. See
ontroller Wiring, page 23.
heck your system electrical continuity after the
initial installation, and then set up a regular schedule
for checking continuity to be sure proper grounding
is maintained. The resistance should not exceed 1
ohm.

Installation
Air Line
Models that Include a Compressor:
An air line is already connected from the compressor
to the pump air inlet.
Using Your Own Compressor:
Install a grounded, flexible air hose from the
compressor to the 3/8 npt(f) pump air inlet.
UsingShopAir:
1. Install an air filter/regulator assembly (H). The
fluid stall pressure will be the same as the setting
of the air regulator. The filter removes harmful
dirt and moisture from the compressed air supply.
2. Locate a bleed-type master air valve (G) close to
the pump and use it to relieve trapped air. Be
sure the valve is easily accessible from the pump
and located downstream from the regulator.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.
3. Locate another master air valve (J) upstream
from all air line accessories and use it to isolate
them during cleaning and repair.
4. Install a grounded, flexible air hose (F) between
the accessories and the 3/8 npt(f) pump air inlet.
F uid Supp y Line
1. onnect a grounded, flexible fluid hose (K) to
the fluid inlet port. The port on pumps with
aluminum, hastelloy, or stainless steel fluid
sections is 1 in npt(f) or 1 in. bspt. On pumps
with polypropylene, conductive polypropylene,
or PVDF fluid sections, the port is a 1 in. raised
face ANSI/DIN flange.
2. If the inlet fluid pressure to the pump is more
than 25% of the outlet working pressure, the
ball check valves will not close fast enough,
resulting in inefficient pump operation. Excessive
inlet fluid pressure also will shorten diaphragm
life. Approximately 3–5 psi (0.02–0.03 MPa,
0.21–0.34 bar) inlet fluid pressure should be
adequate for most materials.
3. For maximum suction lift (wet and dry), see
Technical Data, page 66. For best results, always
install the pump as close as possible to the
material source. Minimize suction requirements
to maximize pump performance.
F uid Out et Line
1. onnect a grounded, flexible fluid hose (N) to
the fluid outlet port. The port on pumps with
aluminum, hastelloy, or stainless steel fluid
sections is 1 in npt(f) or 1 in. bspt. On pumps
with polypropylene, conductive polypropylene,
or PVDF fluid sections, the port is a 1 in. raised
face ANSI/DIN flange.
2. Install a fluid drain valve (L) near the fluid outlet.
3. Install a shutoff valve (M) in the fluid outlet line.
