OPERATING AND SAFETY PRECAUTIONS
READ, UNDERSTAND AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
WARNING
EXPLOSION HAZARD. Do not exceed maxi-
mum uid inlet pressure of 120 PSI (8.3 bar). Operat-
ing at higher pressure can cause explosion, resulting in
property damage or severe injury.
WARNING
USE ONLY WITH COMPRESSED AIR. Do not
use bottled gas products to run the pulsation damp-
ener. Unregulated high pressure bottled gas has the
potential for over-pressurization. Certain gasses, such as
Nitrogen, can cause unpredictable results. The pressure
source MUST BE REGULATED.
WARNING
CHEMICAL COMPATIBILITY HAZARD. Do not
use with certain uids. Incompatible uids may attack
and weaken the housing, causing rupture or explosion,
which can result in property damage or severe injury. See
manufacturer’s information on uid compatibility.
WARNING
DISASSEMBLY HAZARD. Do not disassemble
this unit when it is under pressure. Relieve all mate-
rial pressure in the pumping system before attempting
service or disassembly. Disconnect air lines and carefully
bleed any pressure o the system. Be certain the system
is not maintaining pressure due to a material restriction
in the hose, line, dispensing device or the spray or extru-
sion tip. Failure to relieve pressure, both upstream and
downstream, may result in an injury upon disassembly.
CAUTION
AIR MUST BE SUPPLIED TO THE SHOCK
BLOCKER BEFORE APPLYING FLUID PRESSURE. Fail-
ure to pressurize with air first can damage the dia-
phragm.
CAUTION
ALWAYS RELIEVE THE FLUID PRESSURE
BEFORE REMOVING THE AIR PRESSURE. Failure to re-
lieve uid pressure can damage the diaphragm.
CAUTION
NOT FOR STRUCTURAL SUPPORT. Do not use
this product to support other system components or
use as a step. Improper support can result in fracture of
the housing, causing damage. Plumbing must be sup-
ported to prevent stresses upon it.
NOTICE
Replacement warning labels are available upon
request: “Static Spark & Diaphragm Rupture”pn \ 94080.
WARNING
= Hazards or unsafe practices which
could result in severe personal injury,
death or substantial property damage.
CAUTION
= Hazards or unsafe practices which
could result in minor personal injury,
product or property damage.
NOTICE
= Important installation, operation or
maintenance information.
OPERATING INSTRUCTIONS
WARNING
HEED WARNINGS AS SHOWN IN “OPERATING
AND SAFETY PRECAUTIONS” ABOVE.
AIR REQUIREMENTS
ySupply the unit with clean, dry air.
yA filter capable of filtering out particles larger than 50
microns should be used on the air supply.
INSTALLATION INSTRUCTIONS
yPosition the shock blocker pulsation dampener as close to the
pump discharge as possible (as shown in gure 2).
CAUTION
SUPPORT THE PIPE IMMEDIATELY DOWN-
STREAM FROM THE SHOCK BLOCKER. Support is re-
quired to eliminate forces and moments from the shock
blocker anges and pump manifold. Cantilever support
is suggested immediately downstream from the shock
blocker.
yUse a tee connector after the F-R-L on the pump air sup-
ply line and connect the line to the shock blocker’s valve
body (1/4” ID hose is sufficient). When the air supply to
the pump is shut down, the air to the shock blocker will
be shut down as well.

GENERAL DESCRIPTION
The ARO® shock blocker pulsation dampener is designed
to work with 1:1 ratio pumps having an outlet pressure not
exceeding 120 psi (8.3 bar). The shock blocker will eectively
reduce material pressure variations, surges and shock to pip-
ing and delivery in uid systems during pump reversal. It can
significantly contribute to pulse reduction in low pressure
spray applications.
Accurate selection of wetted material will assure longest ser-
vice life and minimize down time. Several material options
are available for the body and diaphragm materials. Fluid
section materials available include: aluminum, cast iron and
stainless steel. For specific fluid compatibility, consult the
chemical manufacturer.
The shock blocker uses a single air pressurized, flexible di-
aphragm working against the fluid line pressure. Several
diaphragm material options are available to allow custom
matching to the uid material for best compatibility (refer to
the model description chart).
Shock blocker units can also be added in series to provide
additional dampening on the material.
Pressure relief through the exhaust port is a normal compen-
sating function of the control valve in the shock blocker. It
will automatically adjust itself to the required operating pres-
sure once the material pressure has been applied. The pres-
sure supplied to the shock blocker needs to be equal to the
material pressure to provide the proper dampening eect.
AIR AND LUBE REQUIREMENTS
WARNING
EXCESSIVE AIR PRESSURE. Can cause pulsa-
tion dampener damage, personal injury or property
damage.
yA filter capable of filtering out particles larger than 50
microns should be used on the air supply. There is no lu-
brication required other than the“O”ring lubricant which
is applied during assembly or repair.
yIf lubricated air is present, make sure that it is compatible
with the“O” rings and seals in the air motor section of the
pump.
OPERATION
CAUTION
DO NOT EXCEED 120 PSI (8.3 BAR). Operating
at higher pressure can cause explosion, resulting in prop-
erty damage or severe injury.
yPressure relief through the exhaust port is a normal
compensating function of the control valve in the shock
blocker. It will automatically adjust itself to the required
operating pressure once the material pressure has been
applied.
yOperate the system for a few minutes to equalize air and
uid chambers of the pulsation dampener.
PARTS AND SERVICE KITS
Refer to the part views and descriptions as provided on pag-
es 5 and 6 for parts identication and Service Kit information.
yCertain ARO “Smart Parts” are indicated which should be
available for fast repair and reduction of down time.
MAINTENANCE
yProvide a clean work surface to protect sensitive internal
moving parts from contamination from dirt and foreign
matter during service disassembly and reassembly.
yKeep good records of service activity and include pump
in preventive maintenance program.
yBefore disassembling, empty captured material in the
uid cap by tipping the pulsation dampener on end.
