AUTOMATIC PULSATION DAMPENERS
It is the responsibility of the employer to place this information into the hands of the operator.
READ, UNDERSTAND, AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
A Pulsation Dampener is a passive device attached to a reciprocating pump to minimize pressure
pulsations. The pulsation dampener housing contains an isolated pressure-adjustable chamber charged
with a compressed gas to dampen pump pulsations.
Use the Pulsation Dampener only as described in this manual. Any other use not recommended by the
manufacture may cause equipment damage and / or injury to persons.

EXPLOSION HAZARD
The EC Declaration of Incorporation (located near the end
of the manual) states that all pulsation dampener models
have been reviewed as components and conform to the re-
quirements of the EU "Machinery Directive". Additionally,
the metallic pulsation dampener models conform to the EU
"ATEX Directive" and may be used in some potentially ex-
plosive atmospheres as defined by
when the special conditions listed below under the section
"Special Conditions for Pulsation Dampeners in Potentially
Explosive Atmospheres". To clarify, only the metallic pulsation
dampener models conform to the EU "ATEX Directive". Non-me-
tallic (Non Conductive) pulsation dampener models (SB20P-
XXX-X and SB20R-XXX-X) do not conform to the EU "ATEX Direc-
tive". The models are listed on the Declaration of Incorporation
which includes both the Machinery and ATEX directives in the
section titled "This product complies with the following Europe-
an Community Directives".
The explosive hazard assessment of the complete machine
into which this pulsation dampener will be incorporated will
determine the final ATEX marking and conditions. Because
of this Pulsation Dampener's final machine application is not
known and have not been marked with the ATEX directive sym-
bols.
SAFETY INFORMATION - EXPLANATION OF
SAFETY SIGNAL WORDS
WARNING
WARNING indicates a hazardous situation
which, if not avoided, could result in death or serious injury.
CAUTION CAUTION, used with the safety alert symbol,
indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.
NOTICE
NOTICE is used to address practices not relat-
ed to personal injury.
SPECIAL CONDITIONS FOR PULSATION
DAMPENERS IN POTENTIALLY EXPLOSIVE
ATMOSPHERES (ATEX)
WARNING
Non-compliance with any of these special con-
ditions could result in ignition of explosive atmospheres.
Only pulsation dampener models that comply with the EU
z
"ATEX Directive" should be used in potentially explosive
atmospheres.
Rubbing and friction can cause sparks or elevated
z
temperatures may be a source of ignition of an explosive
atmosphere.

HAZARDOUS MATERIALS
HAZARDOUS PRESSURE
WARNING DUST IGNITION HAZARD. Certain dusts may
ignite at pump surface temperature limits. Ensure proper
housekeeping to eliminate dust buildup on the pump.
WARNING
STATIC SPARK. Can cause explosion resulting in
severe injury or death. Ground pulsation dampener and
pumping system.
Sparks can ignite flammable material and vapors.
z
The pumping system and object being sprayed must be
z
grounded when it is pumping, flushing, recirculating or spraying
flammable materials such as paints, solvents, lacquers, etc. or
used in a location where surrounding atmosphere is conducive
to spontaneous combustion. Ground the dispensing valve or
device, containers, hoses and any object to which material is
being pumped.
Use the pulsation dampener grounding lug provided for
z
connection of a ground wire to a good earth ground source.
Use ARO part no. 66885-1 ground kit or a suitable ground wire
(12 ga. / 2.6 mm min.).
Secure pulsation dampener, connections and all contact points
z
to avoid vibration and generation of contact or static spark.
Consult local building codes and electrical codes for
z
specific grounding requirements.
After grounding, periodically verify continuity of electrical path
z
to ground. Test with an ohmmeter from each component (e.g.,
hoses, pulsation dampener, pump, clamps, container, spray
gun, etc.) to ground to insure continuity. Ohmmeter should
show 0.1 ohms or less.
Submerse the outlet hose end, dispensing valve or device in
z
the material being dispensed if possible. (Avoid free streaming
of material being dispensed.)
Use hoses incorporating a static wire or use groundable
z
piping.
Use proper ventilation.
z
Keep flammables away from heat, open flames and sparks.
z
Keep containers closed when not in use.

WARNING
EXPLOSION HAZARD. Models containing alumi-
num wetted parts cannot be used with 1,1,1-trichloroethane,
methylene chloride or other halogenated hydrocarbon sol-
vents which may react and explode.
WARNING If elevated temperatures or elevated vibration
levels are detected, shut the pump off and discontinue its
use until it can be inspected and/or repaired.
WARNING Do not perform maintenance or repairs in an
area where explosive atmospheres are present.
