Installation
In tallation
Installation of this equipment involves potentially
hazardous procedures. Only trained and qualified
personnel who have read and who understand
the information in this manual should install this
equipment.
• All electrical wiring must be done by a qualified
electrician and comply with all local codes and
regulations
Genera Information
The Typical Installation shown is only a guide for
selecting and installing system components. Contact
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
the callouts in the figures.
Tighten C amps Before First Use
After you unpack the pump, and before you use it
for the first time, check all clamps and tighten as
necessary.
Tips to Reduce Cavitation
Cavitation 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. Cavitation damage
and reduced efficiency both result in increased
operating costs.
Cavitation 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.
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 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.

Installation
Mount the 2150T 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 21,
before moving or lifting the pump.
• Do not expose pump or the plastic components
to direct sunlight for prolonged periods.
Prolonged exposure to UV radiation will degrade
natural polypropylene components of the pumps.
NOTICE
The pump is heavy. To prevent damage from
dropping, always use a lift to move the pump. Do
not use the manifolds to lift the pump. Use at least
two straps.
1. For all mountings, be sure the pump is
secured with screws through the mounting
feet (D) and through the mounting bracket
or compressor box on the gear box. See
Dimensions (2150T Pump), page 28.
NOTICE
To prevent pump damage, use all eight
fasteners.
2. Make sure the mounting surface is flat and that
the pump doesn’t wobble.
3. For ease of operation and service, mount the
pump so fluid inlet and fluid outlet ports are easily
accessible.
Mount ng a pump w thout a Gearmotor
A pump without a Graco gearbox and motor will
require a mounting platform to provide support
for the customer-supplied motor and gearbox
and provide alignment with the pump alignment
housing (11 ) and drive shaft (112) without putting
strain on the mounting platform or pump. See
Dimensions (2150T Pump), page 28 for assistance
in fabricating a mounting platform.

Installation
Ground The System
The equipment must be grounded to reduce the
risk of static sparking. Static sparking can cause
fumes to ignite or explode. Improper grounding
can cause electric shock.Grounding provides an
escape wire for the electrical current.
• Always groundtheentirefluidsystemas
described below.
•Followyou
r local fire codes.
Before operating the pump, ground the system as
explained below.
• Pump: All pumps have a ground screw. Loosen
the grounding screw. Insert one end of a 12–gauge
minimum ground wire behind the ground screw
and tighten the screw securely. Connect the clamp
end of the grounding wire to a true earth ground. A
ground wire and clamp, Part 238909, is available
from Graco.
• Motor: 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. Check
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 through
aproperconnectiontoapowersource. Referto
the VFD manual for grounding instructions.
Check 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 pump air inlet (E).
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 pump air inlet.
F uid Supp y Line
1. Use flexible, grounded fluid hoses.
2. For best sealing results, use a standard tri-clamp
or DIN style sanitary gasket of a flexible material
such as EPDM, Buna-N, fluoroelastomer, or
silicon.
3. 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) should be adequate for most
materials.
4. For maximum suction lift (wet and dry), see
Technical Data, page 33. 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. Use flexible, grounded fluid hoses.
2. For best sealing results, use a standard tri-clamp
or DIN style sanitary gasket of a flexible material
such as EPDM, Buna-N, fluoroelastomer, or
silicon.
3. Install a fluid drain valve (L) near the fluid outlet.
4. Install a shutoff valve (M) in the fluid outlet line.

Sanitize the Pump Before First Use
It is the user’s responsibility to properly sanitize
the pump before first use. It is up to the user
whether this will include disassembling and cleaning
individual parts or simply flushing pump with a
sanitizing solution. As necessary, follow the steps
under Start and Adjust the Pump, page 20,or
Flushing and Storage, page 23.
Transfer Mode Vs. Low Pu sation
Mode
When the air pressure is at least 10 psi higher than
the desired outlet pressure, the pump is in Transfer
Mode and no pulsation damping is occurring. To
reduce outlet pulsation, start by setting the air
pressure equal to the desired outlet fluid pressure.
Continue to adjust the air pressure relative to the
outlet fluid pressure. Lower relative air pressures
produce more pulsation damping. Higher relative air
pressures produce better pump efficiency.
Start and Adjust the Pump
1. Be sure the pump is properly grounded. See
Ground The System, page 14.
2. Check fittings to be sure they are tight. Use a
compatible liquid thread sealant on male threads.
Tighten fluid inlet and fluid outlet fittings securely.
3. Placethesuctiontube(ifused)influidtobe
pumped.
OTE: If fluid inlet pressure to the pump is more
than 25% of outlet working pressure, the ball
check valves will not close fast enough, resulting
in inefficient pump operation.
NOTICE
Excessive fluid inlet pressure can reduce
diaphragm life.
4. Place the end of the fluid hose into an appropriate
container.
5. Close the fluid drain valve.
. Turn the air regulator knob to match the desired
fluid stall pressure. Open all bleed-type master
air valves.
7. If the fluid hose has a dispensing device, hold it
open. Be sure all fluid shutoff valves are open.
8. Set the desired frequency on the VFD.
9. Press the start (run) button on the VFD.
10. If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses.
