General Safety
DO NOT misuse dampener, including but not limited
to over-pressurization, modification of parts, using
incompatible chemicals, or operating with worn or
damaged parts. DO NOT use any gases other than
compressed air or clean dry Nitrogen to charge
dampener. DO NOT USE OXYGEN. Any misuse
could result in serious bodily injury, death, fire,
explosion or property damage.
Over-Pressurization
Never exceed the maximum pressure rating for the
dampener model being used. Maximum allowable
working pressure (MAWP) is specified on dampener
serial tag or marked on dampener. Maximum
allowable working pressure (MAWP) is rated at 70°F
(21°C).
Temperature Limits
DO NOT exceed the operating temperature limits for
the body and/or elastomer materials being used.
Excessive temperature will result in dampener
failure. For temperature limits, refer to the
“Temperature Limits” section of the Manual.
Temperature limits are stated at zero psi/bar.
Installation and Start-Up Hazards
Install dampener before charging or pressurizing.
DO NOT start system or assembly without first
charging or pressurizing dampener. Failure to
charge may result in damage to the elastomeric
bladder or PTFE bellows.
Temperature & Pressure Hazard
Temperature and pressure reduce the strength and
chemical resistance of plastic, metal, elastomers and
PTFE.
Charging / Pressurization
Charge or pressurize dampener with compressed air
or clean dry Nitrogen only. DO NOT USE OXYGEN.
Dampener Bladder/Bellows Failure
Dampeners utilize an elastomeric membrane
(bladder) or PTFE bellows to separate system fluid
from the air supply or gas charge. When failure
occurs, system fluid may be expelled from the air
valve. Always perform preventive maintenance and
replace bladder/bellows before excessive wear
occurs. O-rings for PTFE bellows cannot be re-used.
Maintenance Hazards
Never over-tighten fasteners. This may cause
leakage of system fluid and damage to dampener
body. Bolts on metal models should not be reused
as re-torquing reduces bolt strength. AFTER
MAINTENANCE OR RE-ASSEMBLY OF METAL
MODELS, USE NEW FASTENERS AND TORQUE
FASTENERS ACCORDING TO SPECIFICATION ON
DAMPENER TAG.
GENERAL I
NFORMATION
For safe and satisfactory operation of dampener, read all safety warnings and caution statements, and
this complete Manual before installation, startup, operation or maintenance.

NSTALLATION
DO NOT use Oxygen to charge dampener.
Use compressed air or clean dry Nitrogen
only.
Danger of static spark! Grounding precautions
must be considered when dampener is used in
flammable or explosive environments.
DO NOT exceed maximum allowable working
pressure (MAWP) specified on dampener serial
tag or marked on dampener.
ATEX Models must be grounded (earthed)
before operation.
Turn pump off and remove all pressure from
system prior to dampener installation.
DO NOT operate a dampener that is leaking,
damaged, corroded or otherwise unable to
contain internal fluid, air or gas pressure.
Always wear safety glasses and other
appropriate safety equipment when installing,
charging or repairing dampener.
Temperature, pressure and chemicals affect the
strength of plastic, elastomer, and metal
components.
Many plastics lose strength rapidly as
temperature increases. Consult factory if in
doubt.
