Installation
General Information
The surge suppressor uses air pressure and a
diaphragm to maintain a consistent fluid outlet
pressure from a double diaphragm or low-pressure
reciprocating pump. During normal flow, the
suppressor air pressure and fluid pressure are in
equilibrium. A sharp increase in fluid pressure causes
the air inlet port to open, increasing air pressure on the
diaphragm and returning the system to equilibrium.
Conversely, a sharp decrease in fluid pressure causes
the air exhaust port to open, decreasing air pressure
on the diaphragm and allowing the system to return to
equilibrium.
Installation
1. Read this entire manual before installing or
operating the surge suppressor.
2. The surge suppressor fluid inlet must be
connected to the pump’s fluid outlet. If the pump
is aluminum or steel, the surge suppressor may
be plumbed directly to the outlet, using 3/4 npt
fittings. If the pump is acetal or polypropylene,
place the surge suppressor on the floor or some
other solid, level surface near the pump, and
connect the surge suppressor inlet to the pump
outlet with a 3/4” ID hose and 3/4 npt fittings.
Air Exhaust Ventilation
WARNING
Be sure to read TOXIC FLUID HAZARD and FIRE
AND EXPLOSION HAZARD on page 3, before
operating this equipment.
Be sure the system is properly ventilated for your
type of installation. When pumping flammable or
hazardous fluids, you must vent the surge suppressor exhaust air to a safe place, away from people,
animals, food handling areas, and all sources of
ignition. If the diaphragm ruptures, the fluid will be
exhausted along with the air. Place a container at
the end of the air exhaust line to catch the fluid.
See Detail A on page 5.
The minimum size for the air exhaust hose is 3/8 in.
(10 mm) ID x 15 ft (4.6 m). If a longer hose is required,
use a larger diameter hose.
1. Remove the muffler from the surge suppressor
exhaust port. Install an exhaust hose in the
exhaust port, and connect the muffler to the other
end of the hose. Avoid sharp bends or kinks in the
hose. See Detail A on page 5.
2. Place a container at the end of the air exhaust line
to catch fluid in case the diaphragm ruptures.
CAUTION
Do not plumb the surge suppressor directly onto the
fluid outlet of an acetal or polypropylene pump.
Those pumps cannot support the weight of the
suppressor and will suffer damage or rupture.
3. Connect an air line from the pump’s air regulator to
the air inlet of the surge suppressor. In systems
using a 1:1 ratio pump, the air pressure supplied to
the suppressor will be the same as that supplied to
the pump.
4. Use a compatible, liquid thread sealant on all male
threads. Tighten all connections firmly to avoid air
or fluid leaks.
CAUTION
To avoid pump damage, do not overtighten the
fittings to the pump.
6
308178
WARNING
Never operate the surge suppressor without the
muffler or an air exhaust line installed in the air
exhaust port. If the air exhaust port is left open and
the diaphragm shaft works loose from the bolt, the
shaft could be propelled out of the housing, causing injury.
Operation and Maintenance
Operating the Surge Suppressor
1. Be sure the system is properly grounded. Read
and follow FIRE AND EXPLOSION HAZARD, on
page 3.
2. Check all fittings to be sure they are tight. Be sure
to use a compatible liquid thread sealant on all
male threads, and do not overtighten the fittings
into the pump.
WARNING
To prevent overpressurization of the surge suppressor, never exceed 100 psi (0.7 MPa, 7 bar)
fluid inlet pressure or 100 psi (0.7 MPa, 7 bar) air
inlet pressure. In systems using pumps with a ratio
greater than 1:1, reduce the air inlet pressure to
the pump as necessary to keep the fluid and air
inlet pressures to the surge suppressor within
these limits.
3. Check that the muffler or air exhaust line is
securely connected to the air exhaust port on the
top of the housing.
WARNING
Never operate the surge suppressor without the
muffler or an air exhaust line installed in the air
exhaust port. If the air exhaust port is left open and
the diaphragm shaft works loose from the bolt, the
shaft could be propelled out of the housing, causing injury.
4. Start the pump as explained in your separate
pump manual. In systems using a 1:1 ratio pump,
the air pressure supplied to the suppressor will be
the same as that supplied to the pump.
CAUTION
In systems using pumps with a ratio greater than 1:1,
fluid may escape into the surge suppressor air line
and contaminate the air supply if the diaphragm fails.
Installation of a check valve in the air line will prevent
fluid contamination of the air line.
Flushing the System
Flush the system regularly, using a compatible solvent.
Do not allow fluid to dry in the pump or surge
suppressor. Always flush the pump and surge
suppressor before storing them for any length of time.
5. Allow the pump to cycle slowly until all air is
pushed out of the surge suppressor and lines, and
the pump is primed. The system is now ready for
normal operation.
Place the pump suction tube in the solvent container.
Run the pump long enough to thoroughly clean it, the
surge suppressor, hoses, and any guns or valves used
in the system. Close the pump air regulator. Remove
the suction hose from the solvent.
NOTES:
Shutdown
When using a pump with a ratio greater than 1:1, the
air pressure supplied to the surge suppressor and the
air pressure supplied to the pump must be at the same
ratio as the pump to prevent overpressurization of the
surge suppressor. See the following examples.
Remove the suction hose from the fluid container and
run the pump until the fluid is forced out of the system.
Then shut off the air supply immediately.
D In a system using a 2:1 ratio pump, air pressure
supplied to the surge suppressor should be twice
as high as air pressure to the pump. If the air
pressure supplied to the pump is 50 psi (0.34 MPa,
3.4 bar), you should supply 100 psi (0.7 MPa,
7 bar) air pressure to the surge suppressor.
D In a system using a 4:1 ratio pump, air pressure
supplied to the surge suppressor should be four
times as high as air pressure to the pump. If the
air pressure supplied to the pump is 25 psi
(0.17 MPa, 1.7 bar), you should supply 100 psi
(0.7 MPa, 7 bar) air pressure to the surge
suppressor.

Graco Standard Warranty
Graco warrants all equipment manufactured by Graco and bearing its name to be free from defects in material and workmanship on the
date of sale to the original purchaser for use. With the exception of any special, extended, or limited warranty published by Graco,
Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be
defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written
recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by
faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or
substitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,
installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for
verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The
equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect
in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT
NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any
other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
date of sale.
Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular purpose in connection
with accessories, equipment, materials or components sold but not manufactured by Graco. These items sold, but not manufactured
by Graco (such as electric motors, switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide
purchaser with reasonable assistance in making any claim for breach of these warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment
hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract,
breach of warranty, the negligence of Graco, or otherwise.
