Blacoh SENTRY CIP User manual

Installation and Operation Manual
CIP Sanitary Flow Through Dampener Models
SENTRY dampeners are pressure vessels containing a flexible bladder or bellows inside that separates an
inert pressurized gas (air or Nitrogen) from a system fluid in the lower chamber. Depending on how dampeners
are configured, they are used as Pulsation Dampeners, Inlet Stabilizers or Surge Suppressors to control
pressure fluctuations and spikes in liquid piping systems.
Dampeners work on the principle that volume is inversely proportional to pressure (P1V1=P2V2). Compressed
air or Nitrogen (never Oxygen) is introduced into the non-wetted side of the dampener. The gas charge is
contained by the bladder or bellows preventing contact between the system fluid and the gas.
When the dampener is sized correctly, properly installed and charged according to the instructions provided it
will greatly reduce the damaging effects of pressure variations in piping systems and significantly improve the
efficiency of transferring liquids.
All dampeners manufactured by BLACOH use pressure bodies made in the USA to insure quality. Prior
to shipment, each and every dampener is factory tested at design pressure or higher to assure proper
function and leak-free operation.

operation and maintenance of dampener.
WARNINGS Danger of serious injury or death could occur if these warnings are ignored.
CAUTIONS Equipment damage, injury or death could occur if these cautions are not observed.
NOTES Special instructions for safe and satisfactory installation, operation and maintenance.
General Safety
CAUTION!
Observe all safety symbols in installation and
operation instructions.
The internal dampener pressure will equal the
maximum fluid pressure of the system in which it is
installed.
DO NOT exceed maximum allowable working
pressure (MAWP) specified on dampener serial tag
or marked on dampener. If serial tag is missing, DO
NOT use dampener without consulting distributor or
factory for maximum pressure rating.
Always make sure safety shutoff valves, regulators,
pressure relief valves, gauges, etc. are working
properly before starting system or assembly.
Verify dampener model received against purchase
order and shipper.
Before starting a system or assembly make certain
the discharge point of the piping system is clear and
safe, and all persons have been warned to stand
clear.
DO NOT put your face or body near dampener
when the system or assembly is operating or
dampener is pressurized.
DO NOT operate a dampener that is leaking,
damaged, corroded or otherwise unable to contain
internal fluid, air or gas pressure.
DO NOT pump incompatible fluids through
dampener. Consult distributor or factory if you are
not sure of the compatibility of system fluids with
dampener materials.
Dampeners are designed to operate with
compressed air or clean dry Nitrogen only. Other
compressed gases have not been tested and may
be unsafe to use. DO NOT USE OXYGEN.
Always shut off air supply, remove internal
dampener pressure and shut dampener isolation
valve before performing dampener maintenance or
repair.
Remove all pressure from dampener AND pumping
system before disassembly, removal or
maintenance.
Static spark can cause an explosion resulting in
severe injury or death. Ground dampeners and
pumping system when pumping flammable
fluids or operating in flammable environments.
NOTE: EC standard EN-13463-1 and EN-13463-5
(ATEX) require grounding (earthing) on

Equipment Misuse Hazard
CAUTION!
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 this 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 should
not be reused as re-torquing reduces bolt strength. After
dampener maintenance or re-assembly, use new
fasteners and torque fasteners according to
specification on dampener serial tag. If serial tag is
missing, consult distributor or factory for torque
specifications.
GENERAL Information
For safe and satisfactory operation of dampener read all safety warnings, caution statements and this complete
Manual before installation, startup, operation or maintenance.
Must Read Before Installation
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.

BLACOH Fluid Control 4
Installation Notes
Dampening of flow pulsations can only be effective if a minimum of 5 to 10 psi (0.4 to 0.7 bar) back pressure
downstream of dampener is available. A BLACOH back pressure valve may be required downstream of
dampener, except when dampener is used as an inlet stabilizer for the inlet side of the pump.
It is recommended that a BLACOH pressure relief valve be installed in all pump systems to ensure compliance
with pressure limits on system equipment.
To avoid possible damage to bladder/bellows from a system pressure test:
Adjustable and Chargeable models — charge dampener to 80% of the system test pressure prior to test.
Automatic model — prior to test, dampener must be equipped with a constant source of compressed air with
pressure equal to or greater than system test pressure.
Inlet Stabilizer model — maximum pressure test 30 psi (2.0 bar), charge to 20 psi (1.3 bar) for system pressure
test.
Install dampener in-line as close to the pump discharge/inlet or quick closing valve as possible. Dampener
installation should be no more than ten pipe diameters from pump discharge/inlet or quick closing valve.
It is recommended that an isolation valve be installed between the dampener and system piping.
ATEX Standard
Certain models made for the European market comply with the ATEX standard for use in potentially explosive
atmospheres. These models have the AT designation at the end of the part number and comply with EC standard
EN-13463-5 with protection degree of II 2GD TXC. AT models have a grounding lug and must be grounded
(earthed) before operation.
Maintenance
Remove all pressure from dampener AND pumping system before disassembly, removal or maintenance.
Dampeners require very little maintenance. There is only ONE wear part – the elastomeric bladder or the PTFE bellows.
There is no need for lubrication.
Elastomeric bladder replacement should be part of a preventive maintenance program. Dampeners used in conjunction with
diaphragm pumps should have the bladders replaced at least every second time the diaphragms in the pump are replaced.
As with any pumping system, wear is dependent on many factors including material, temperature, chemicals, fluid
abrasiveness and system design. This suggested maintenance program may need to be adjusted according to specific
applications.
Periodic inspection of the dampener and fasteners should be conducted to visually check for signs of over-pressurization,
fatigue, stress or corrosion. Body housings and fasteners must be replaced at first indication of deterioration.
CAUTION! Replace nut and bolt fasteners at each re-assembly with fasteners of equal grade/strength
value. DO NOT re-use old nuts and bolts.
After the initial torque of fasteners, bolts may lose strength when re-torqued. Failure to replace both nuts and bolts upon
each vessel reassembly will void the product warranty given by the manufacturer and the manufacturer will have no liability
whatsoever for any vessel failure or malfunction.
Where dampeners are used in corrosive environments, nut and bolt fasteners should be regularly inspected and replaced
with nut and bolt fasteners of equal grade/strength value if corrosion is observed. Failure to conduct such regular inspections
and replacement will void the product warranty given by the manufacturer and the manufacturer will have no liability
whatsoever for any vessel failure or malfunction.
IMPORTANT! After maintenance or re-assembly, use new fasteners and torque fasteners according to
specification on dampener serial tag. If tag is missing, consult distributor or factory for specifications.
DO NOT use dampener if the fasteners (nuts and bolts) are corroded. Check for fastener corrosion frequently,
especially in atmospheres containing salt or corrosive chemicals, or if dampener leakage has occurred.

5 BLACOH Fluid Control
Temperature Limits
Operating temperatures are based on the maximum temperature of the wetted dampener components
only. Non-wetted dampener components may have a lower temperature limit. Temperature and certain
chemicals may reduce the maximum allowable working pressure (MAWP) of the dampener.
CAUTION! Plastic (non-metallic) body materials lose strength as temperature increases, which reduces
the maximum pressure sustainable by the material. All plastic materials must have an appropriate de-
rating factor applied when working at elevated temperatures above 73.4°F (23°C) to determine maximum
allowable working pressure (MAWP).

Installation & Operation Instructions: CIP Sanitary Flow Through Models
ATEX models must be grounded (earthed) before operation.
Turn pump off and remove all pressure from system prior to dampener installation.
Remove all pressure from dampener AND pumping system before disassembly, removal or maintenance.
Use compressed air or clean dry Nitrogen to charge dampener. DO NOT USE OXYGEN.
DO NOT exceed 150 psi (10.3 bar) maximum allowable working pressure (MAWP). Check maximum pressure rating
specified on dampener serial tag. If tag is missing, consult distributor or factory for specifications.
Always wear safety glasses and other appropriate safety equipment when installing, charging or repairing dampener.
Read and observe all safety warnings and instructions in this Manual before installation, operation or repair.
Before performing a system pressure test, dampener must be charged with 30% of system test pressure to avoid
possible damage to bladder.
Dampener must be cleaned and/or sanitized before use in a sanitary system.
Charge Notes Read Before Installation
To be effective, dampener must be properly charged with compressed air or clean dry Nitrogen. DO NOT USE
OXYGEN. The gas used to charge the dampener may be required to meet standards established by 3A, EHEDG
and/or other agencies. The dampener cannot be charged until properly installed in the system.
The CIP dampener is available with two types of air controls for gas charging.
Adjustable Model
The adjustable model uses a self-relieving regulator and pressure gauge to set and control the gas charge in the
dampener. This model provides a means to easily adjust pressure to maximize dampener response but, a
compressed air line must be permanently attached to the dampener.
Chargeable Model
The chargeable model uses a Schrader type fill valve and pressure gauge to pre-charge the dampener. This type of
control is generally used when no source of compressed air is available near the dampener.
IMPORTANT! Do not charge dampener to more than 30% of pump discharge pressure. Overcharging
dampener may result in bladder failure. If dampener is overcharged compared to pump discharge
pressure, bladder will close and pump flow will be reduced or stopped. Symptoms of overcharging
include reduced flow, dampener vibration and/or pump shutdown.
Installation for Pump Discharge Pulsation Read Before Installation
Installation Position
The CIP dampener is a flow-through design with 2 ½” tri-clamp connections on each end and should be installed in-line, as
close to the pump discharge as possible to absorb the pulse at its source and before any downstream equipment such as risers,
valves, elbows, meters, or filters. Dampener installation should be no more than ten pipe diameters from pump discharge. For
mechanical cleanability (clean-in-place or CIP), dampener can be installed in a downward angled position to assure complete
drainage. Vertical or horizontal installation is acceptable for in-line application (see FIGURE 1).
IMPORTANT! Dampener must be installed in the system with the arrow on the dampener body
pointing away from the pump and in the direction of fluid flow.
IMPORTANT! The tri-clamp style clamps used to install the dampener in the system must be installed
correctly and tightened completely, the clamps create product seal AND provide compressed gas
sealing so the dampener will hold the pressure charge.

7 BLACOH Fluid Control
Dampener can be installed vertically on a tee in the system piping. Vertical installation requires a cap be installed on the top
end of dampener. This type of installation, referred to as appendage installation, will cause product holdup and cannot be
used for mechanical (CIP) applications. If a flexible connector is used in the piping system, attach dampener to the pump’s
discharge outlet and connect the flexible connector to the downstream end of dampener.
FIGURE 1
Chargeable Model Read Before Installation
Charging and Start-Up (see Charge Notes)
Chargeable models do not require an air line connection. Dampener should be pre-charged with 3A standard approved
compressed air or clean dry Nitrogen. Use a hand pump, Nitrogen tank or air compressor to charge dampener. DO NOT
USE OXYGEN. Charging hose kits are available from BLACOH.
Prior to starting the pump, pre-charge the dampener to approximately 30% of expected system pressure and replace fill
valve cap. DO NOT USE OXYGEN. The pre-charge pressure in the dampener must always be lower than pump discharge
pressure. Start the pump to generate system pressure. The dampener charge pressure may need to be adjusted up or down
to be most effective in reducing pulsation. NOTE: The most effective method to set the proper dampener charge is to install
a glycerin-filled pressure gauge downstream of the dampener and adjust the dampener to minimize needle movement on the
gauge.
Once system pressure is in contact with the bladder, the gas charge will be compressed to the system pressure and
the dampener gauge will read the system pressure, not the initial charge pressure. Once working pressure is
achieved, adjustment may be necessary. Gradually increase or decrease the gas charge in the dampener by bleeding or
filling through the gas valve. Allow the system to respond to each adjustment (this may take a minute or two) before making
further adjustments. NOTE: It is important to replace the charge valve cap tightly after charging because pressure can be
slowly lost through a valve without a cap.

BLACOH Fluid Control 8
Adjustable Model Read Before Installation
Step 1 – Air Line Connection
Using a 1/4” flexible air hose (I.D. of the hose must be 1/4” or 6.4 mm minimum) run an air line from a compressed gas
source to the one-way check valve on the dampener’s regulator.
DO NOT remove one-way check valve. The check valve prevents fluid back flow through the air hose in case of bladder
failure. The air supply pressure to the dampener must be greater than the pump discharge and/or system pressure. If the
dampener is being used in conjunction with a pneumatically operated pump, a tee can be used to run the air line to the
dampener from the existing pump air supply line (see FIGURE 1). The tee should be placed before any in-line pump
instrumentation such as a filter, regulator, lubricator or other pump control valve.
Step 2 – Charging and Startup
Prior to starting the pump, adjust the regulator on dampener to approximately 30% of expected system pressure at the
pump’s discharge outlet. For example, if the liquid pressure at the pump discharge is 60 psi (4.1 bar), initial dampener
charge should be 20 psi (1.3 bar).
Note: Dampener must be charged before the pump is started. If dampener pressure charge is set too high, then the bladder
will be squeezed and flow will be restricted. The most effective way to set the proper dampener charge is to install a glycerin-
filled pressure gauge downstream of the dampener and adjust the dampener to minimize needle movement on the gauge.
After the pump is started minor pressure adjustments to the dampener may be required to maximize dampener performance.
Since the dampener regulator is the self-relieving type, it is easy to raise or lower the dampener pressure to obtain best
dampening results.
Once system pressure is in contact with the bladder, the air charge will be compressed to the system pressure and
the dampener gauge will read approximately 1/3 to 1/2 of system pressure, not the initial charge pressure. Once
working pressure is achieved, adjustment may be necessary. Gradually increase or decrease the air charge in the dampener
by bleeding or filling through the self-relieving pressure regulator. Allow the system to respond to each adjustment (this may
take a minute or two) before making further adjustments.
Maintenance and Repair Read Before Installation
The only maintenance required is the periodic checking of the gas pressure charge on the Chargeable model.
Normally, if dampener is properly installed, pre-charge pressure should be checked every two to three months or
when dampener effectiveness is reduced, which indicates a loss of charge. Refer to charging instructions above.
Bladder Replacement
IMPORTANT! Bladder must be installed in one direction only or bladder damage will occur. The side of the
bladder has an arrow molded in it indicating the direction of fluid flow inside the dampener. The arrow on the
bladder must point in the same direction as the arrow on the dampener body. Dampener must be installed in
the system with the arrow on the dampener body pointing away from the pump in the direction of fluid flow.
1. Before replacing the bladder, dampener must be removed from the pipe system.
2. To remove the bladder, fold the bladder lip seal down into the center of the bladder while pulling the bladder
out from the opposite end of dampener body.
3. To install a new bladder, insert the bladder into one end of dampener body as far as it will go. Reach into the
opposite end, fold the lip seal edges toward the bladder center and pull the bladder end out of the body.
Pushing the bladder from the opposite end while pulling will assist in bladder installation. A sanitary/food grade
oil can be applied to the lip seal to help with installation.
4. If dampener is used in a sanitary application, dampener body must be cleaned and sanitized internally before
reuse after repair.
