OPERATING AND SAFETY PRECAUTIONS
READ, UNDERSTAND AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
WARNING
EXPLOSION HAZARD. Do not exceed maximum
uid inlet pressure of 100 PSIG (6.9 bar). Operating 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 Shock Blocker. Unregulated
high pressure bottled gas has the potential for over-pressuriza-
tion. Certain gasses, such as Nitrogen, can cause unpredictable
results. The pressure source MUST BE REGULATED.
WARNING
TEMPERATURE LIMITATIONS. Do not exceed
maximum temperature limits of; (Polypropylene 175°F),
(Conductive Acetal 180°F), (PVDF 200°F). Excessive oper-
ating temperatures can weaken the body material. Limits are
based on mechanical stress only.
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 informa-
tion on uid compatibility.
WARNING
DISASSEMBLY HAZARD. Do not disassemble this
unit when it is under pressure. Relieve all material pressure in
the pumping system before attempting service or disassembly.
Disconnect air lines and carefully bleed any pressure o the sys-
tem. Be certain the system is not maintaining pressure due to
a material restriction in the hose, line, dispensing device or the
spray or extrusion tip. Failure to relieve pressure, both upstream
and downstream, may result in an injury upon disassembly.
WARNING
MATERIAL ATOMIZATION. The relief / exhaust
valve must be piped away from the work area. In the event of a
bladder rupture, the material can be atomized and forced out
the relief / exhaust valve.
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 hous-
ing, causing damage. Plumbing must be supported to prevent
stresses upon it. Install using the mounting hardware supplied.
NOTICE
Replacement warning labels (PN 93793) are
available upon request.
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.
GENERAL DESCRIPTION
INSTALLATION INSTRUCTIONS
The ARO® Shock Blocker pulsation dampener is designed to work
with 1:1 ratio pumps having an outlet pressure not exceeding 100
psig (6.9 bar). The Shock Blocker will effectively reduce material
pressure variations, surges and shock to piping 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 service life
and minimize down time. Several material options are available for
the body and bladder materials. Body materials available include:
Polypropylene, Conductive Acetal and PVDF. Use Conductive Acetal
and ground cable when pumping ammable materials.
The Shock Blocker uses a single air pressurized, flexible bladder
working against the fluid line pressure. Several bladder material
options are available to allow custom matching to the uid material
for best compatibility (refer to the model description chart).
The use of an air tamer for a higher level of automatic pressure ad-
justment and accuracy is important. It uses a sensing rod to detect
the position of the bladder and an automatic air valve to adjust
the air line pressure or to exhaust excessive pressure in the bladder
chamber as needed. An air pressure gauge is standard to monitor
the air side internal chamber pressure.
Shock Blocker units can also be added in series to provide addition-
al dampening on the material.
WARNING
HEED WARNINGS AS SHOWN IN “OPERATING
AND SAFETY PRECAUTIONS’’ ABOVE.
AIR REQUIREMENTS
Clean, dry air should be used to charge the unit. A lter capable of
ltering out particles larger than 50 microns should be used on the
air supply.
INSTALLATION INSTRUCTIONS
Position the Shock Blocker pulsation dampener as close to the
pump discharge as possible.
Use the ground lug and optional 66885-1 grounding cable kit with
the Conductive Acetal models (SB10D-XDS-X) in applications where
ammable uids are used, to help guard against static spark hazard
resulting in possible re or explosion. The terminal on the end of
the ground wire must be removed and the wire stripped back 1/2”
(13 mm) to be accepted by the Shock Blocker ground tting. Mount
the Shock Blocker in one of the recommended positions as illustrat-
ed in gure 2, page 3.
Different materials affect the mounting configuration. For best
performance and typical applications, mount the Shock Blocker up-
right versus horizontally. Heavier particles in some uids may settle
out. Gravity will help discharge heavier particles when mounted
vertically.
In many situations, mounting the unit directly to the pump outlet
would not be advisable due to the added weight of the unit. It
should be independently mounted and plumbed using flexible
tubing and not expected to physically support other components.
The material ow should be in the direction of the Shock Blocker,
for best results, not passing by at right angles (see gure 2, page 3).
Use the mounting base as provided and additional mounting kit
66108 is also available to gain extra vertical height. This may be nec-
essary when using pumps with outlets 1” and larger, because of the
increased size and space requirements of the fittings. The second
mounting kit is inverted to provide an elevated base (see page 7).
When connecting pipe, cut or press the “knock-out” panels from
the pedestal base as needed to accommodate piping. Do not alter
or cut out other parts of the pedestal.
Shock Blockers used in series should be installed as illustrated in
gure 2, page 3.
All models are completely automatic, no further adjustment is
needed after initial set-up. The control device is activated by chang-
es in the material pressure and it will self-adjust the air pressure to
the correct level regardless of the material used. Refer to operating
instructions on page 3.

Connect the air tamer 3/8 - 18 NPT air inlet to the regulated air inlet
supply hose.
When pumping fluids that may pose a hazard to human health,
connect a drain line to the 1/8 - 27 NPT exhaust port as a safety pre-
caution. Tubing and ttings are not supplied.
WARNING
In the event of a bladder rupture, the material being
pumped could leak from the exhaust port. Route the drain line to
a location where escaping air, material or air containing atomized
material will not harm personnel or property.
OPERATION
CAUTION
DO NOT EXCEED 100 PSIG (6.9 BAR) MAXIMUM
AIR INLET PRESSURE SUPPLIED TO THE AIR INLET.
Pressure relief through the exhaust port is a normal compensating
function of the control valve in the air tamer. It will automatically
adjust itself to the required operating pressure once the material
pressure has been applied.
NOTE: THE AIR PRESSURE SUPPLIED TO THE AIR TAMER NEEDS
TO BE EQUAL TO THE MATERIAL PRESSURE TO PROVIDE THE
PROPER DAMPENING EFFECT.
1. Connect a regulated air supply (100 psig / 6.9 bar maximum) to
the air tamer inlet.
CAUTION
AIR MUST BE SUPPLIED TO THE AIR TAMER BE-
FORE APPLYING FLUID PRESSURE. Failure to pressurize with
air rst can damage the bladder.
2. Reconnect the air supply to the pumping system.
3. Operate the pump to generate material pressure.
4. MONITOR THE GAUGE for the air pressure needed to deliver the
best pulsation dampening action.
5. Operate the system a few minutes between pressure adjust-
ments, allowing for system equalizing.
MAINTENANCE
NOTE: BE CERTAIN TO DISCONNECT THE AIR SUPPLY AND RE-
LIEVE FLUID PRESSURE BEFORE ATTEMPTING SERVICE OR
DISASSEMBLY.
CAUTION
RELIEVING AIR PRESSURE WILL NOT AFFECT THE
FLUID SYSTEM PRESSURE. THE GAUGE READING COULD
FALSELY REPRESENT ANY RESIDUAL FLUID PRESSURE.
TROUBLESHOOTING
No dampening eect or erratic performance.
Check for bladder rupture.
Check for blocked or restricted outlet hoses.
Check for a solid object lodged in the uid inlet or in the blad-
der area.
Check the air supply. Make certain the air pressure to the tamer
is equal to the uid pressure. The air tamer will automatically
adjust to the operating pressure.
Fluid or air leakage at the top.
Check for bladder rupture.
Check for defective pressure relief valve.
Check for damaged (105)“O” ring.
Check the tightness of the ange bolts (50 - 60 in. lbs / 5.6 -
6.8 Nm).
Cracks in the housing.
Discontinue use. This would indicate possible uid incompati-
bility with the Shock Blocker body material.
INSTALLATION MOUNTING CONFIGURATIONS
Installation Note: The material ow should ow directly towards the Shock Blocker, not at a right angle to the ow path.
