GENERAL

The ARO Shock Blocker, pulsation dampener is designed to work with
1:1 ratio pumps having an outlet pressure not exceeding 100 p.s.i. (6.9
bar). The Shock Blocker will effectively reduce material pressure variaĆ
tions, surges and shock to piping and delivery in fluid 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:PolyproĆ
pylene, Conductive Acetal and Pure Kynar. UseConductive Acetaland
ground cable when pumping flammable materials.
The Shock Blocker uses a single air pressurized, flexible bladder workĆ
ing against the fluid line pressure. Several bladder material options are
available toallow custommatching tothe fluid materialfor bestcompatĆ
ibility (refer to the model description chart).
The use of an air tamer for a higher level of automatic pressure adjustĆ
ment andaccuracy isimportant. It uses a sensingrod to detectthe posiĆ
tion 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 interĆ
nal chamber pressure.
Shock Blocker units can also be added in series to provide additional
dampening on the material.

OPERATING

READ, UNDERSTAND AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.

WARNING EXPLOSION HAZARD. Do not exceed maximum

fluid inlet pressure of 100 p.s.i. (6.9 bar). Operating at higher

pressure can cause explosion, resulting in property damage or seĆ
vere 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 overĆpressurization.
Certain gasses, such asNitrogen, cancause unpredictableresults.
The pressure source MUST BE REGULATED.

WARNING TEMPERATURE LIMITATIONS. Do not exceed

maximum temperature limits of; (POLYPROPYLENE 150_F),
(CONDUCTIVE ACETAL180_F), (KYNAR200_F). ExcessiveopĆ

erating temperatures can weaken the body material. Limits are
based on mechanical stress only.

WARNING CHEMICAL COMPATIBILITY HAZARD. Do not

use with certain fluids. Incompatible fluids may attack and weakĆ

en the housing, causing rupture or explosion, which can result in
property damage or severe injury. For specific fluid compatibility,
consult the chemical manufacturer.

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 off the sysĆ
tem. Becertain thesystem isnot maintainingpressure due to a maĆ

AND SAFETY PRECAUTIONS

terial restriction in the hose, line, dispensing device or the spray or
extrusion tip. Failure to relieve pressure both up stream and downĆ
stream 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 housing, causĆ

ing damage.Plumbing must be supported to prevent stressesupon
it. Install using the mounting hardware supplied.

NOTICE Replacement warning label (PN 93793) is availĆ

able upon request.

INSTALLATION INSTRUCTIONS

WARNING HEED WARNINGS AS SHOWN IN ``OPERATING

AND SAFETY PRECAUTIONS'' ABOVE.

AIR REQUIREMENTS

Clean, dry air should be used to charge the unit.
A filtercapable offiltering outparticles largerthan 50 microns shouldbe
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 66885Ć1 grounding cable kit with the
Conductive Acetal models (SB10DĆXDSĆX) in applications where flamĆ
mable fluids are used, to help guard against static spark hazard resultĆ
ing in possible fire 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 fitting.
Mount the Shock Blocker in one of the recommended positions as illusĆ
trated in figure 1, page 3.
Different materials affect the mounting configuration. For best perforĆ
mance and typical applications, mount the Shock Blocker upright verĆ
sus horizontally. Heavier particles in some fluids 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 indeĆ
pendently mounted and plumbed using flexible tubing and not exĆ

pected to physically support other components.
The material flow should be in the direction of the Shock Blocker, for
best results, not passing by at right angles (see figure 1, page 3).
Use the mounting base as provided and additional mounting kit 66108
is also available to gain extra vertical height. This may be necessary
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 ``knockĆout'' panels from the
pedestal base as needed to accommodate piping. Do not alter or cut
out other parts of the pedestal.
Shock Blockersused in series shouldbe installed as illustratedin figure
1, page 3.
All models are completely automatic, no further adjustment is needed
after initial setĆup. The control device is activated by changes in the maĆ
terial pressure and it will selfĆadjust the air pressure to the correct level
regardless of the material used. Referto operatinginstructions onpage

3.
Connect the air tamer 3/8 Ć 18 n.p.t. air inlet to the regulated air inlet
supply hose.
When pumping fluids thatmay posea hazardto human health, connect
a drain line to the 1/8 Ć 27 n.p.t. exhaust port as a safety precaution.
Tubing and fittings 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 P.S.I. (6.9 BAR) MAXIMUM

AIR INLET PRESSURE SUPPLIED TO THE AIR INLET.

Pressure reliefthrough theexhaust portis a normalcompensating funcĆ
tion of the control valve in theair 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 PROĆ
VIDE THE PROPER DAMPENING EFFECT.

1. Connect a regulated air supply (100 p.s.i. /6.9 bar maximum) to the
air tamer inlet.

CAUTION AIR MUST BE SUPPLIED TO THE AIR TAMER

BEFORE APPLYING FLUID PRESSURE. Failure to pressurize

TROUBLE SHOOTING

No dampening effect or erratic performance.

S Check for bladder rupture.
S Check for blocked or restricted outlet hoses.
S Check for a solid object lodged in the fluid inlet or in the bladder

area.

S Check the air supply. Make certainthe airpressure supplyavailable

matically adjust to the operating pressure.

with air first 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 adjustments,
allowing for system equalizing.

SERVICE

NOTE: BE CERTAIN TO DISCONNECT THE AIR SUPPLY AND REĆ
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 PRESĆ
SURE.

Fluid or air leakage at the top.

S Check for bladder rupture.
S Check for defective pressure relief valve.
S Check for damaged (105) ``O" ring.
S Check the tightness of theflange bolts (50 Ć 60in. lbs /5.6 Ć 6.8Nm).

Cracks in the housing.

S Discontinue use. This would indicate possible fluid incompatibility

with the Shock Blocker body material.

INSTALLATION MOUNTING CONFIGURATIONS
