OPERATING AND SAFETY PRECAUTIONS
READ, UNDERSTAND AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
WARNING
uid inlet pressure of 120 p.s.i. (8.3 bar). Operating at higher
pressure can cause explosion, resulting in property damage or
severe injury.
WARNING
bottled gas products to run the pulsation dampener. Un-
regulated high pressure bottled gas has the potential for overpressurization. Certain gasses, such as Nitrogen, can cause unpredictable results. The pressure source MUST BE REGULATED.
WARNING
use with certain fluids. Incompatible fluids 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
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
system. 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.
EXPLOSION HAZARD. Do not exceed maximum
USE ONLY WITH COMPRESSED AIR. Do not use
CHEMICAL COMPATIBILITY HAZARD. Do not
DISASSEMBLY HAZARD. Do not disassemble this
CAUTION
AIR MUST BE SUPPLIED TO THE SHOCK BLOCKER
BEFORE APPLYING FLUID PRESSURE. Failure to pressurize
with air rst can damage the diaphragm.
CAUTION
ALWAYS RELIEVE THE FLUID PRESSURE BEFORE
REMOVING THE AIR PRESSURE. Failure to relieve 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 hous-
ing, causing damage. Plumbing must be supported 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,

CAUTION
SUPPORT THE PIPE IMMEDIATELY DOWNSTREAM
FROM THE SHOCK BLOCKER. Support is required to eliminate
forces and moments from the shock blocker anges and pump
manifold. Cantilever support is suggested immediately downstream from the shock blocker.
Use a tee connector after the F-R-L on the pump air supply line
y
and connect the line to the shock blocker’s valve body (1/4”
i.d. hose is su cient). 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
p.s.i. (8.3 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 diaphragm materials. Fluid section materials available include: aluminum, cast iron and stainless steel. For specific
uid compatibility, consult the chemical manufacturer.
The shock blocker uses a single air pressurized, exible diaphragm
working against the uid 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 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. The pressure 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
dampener damage, personal injury or property damage.
A lter capable of ltering out particles larger than 50 microns
y
should be used on the air supply. There is no lubrication required other than the “O” ring lubricant which is applied during
assembly or repair.
If lubricated air is present, make sure that it is compatible with
y
the “O” rings and seals in the air motor section of the pump.
EXCESSIVE AIR PRESSURE. Can cause pulsation
OPERATION
CAUTION
at higher pressure can cause explosion, resulting in property
damage or severe injury.
Pressure relief through the exhaust port is a normal compen-
y
sating 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.
Operate the system for a few minutes to equalize air and uid
y
chambers of the pulsation dampener.
DO NOT EXCEED 120 P.S.I. (8.3 BAR). Operating
PARTS AND SERVICE KITS
Refer to the part views and descriptions as provided on pages 4
and 5 for parts identi cation and Service Kit information.
Certain ARO “Smart Parts” are indicated which should be avail-
y
able for fast repair and reduction of down time.
MAINTENANCE
Provide a clean work surface to protect sensitive internal mov-
y
ing parts from contamination from dirt and foreign matter during service disassembly and reassembly.
Keep good records of service activity and include pump in pre-
y
ventive maintenance program.
Before disassembling, empty captured material in the uid cap
y
by tipping the pulsation dampener on end.
