Sayfayı YazdırMust Read Before Installation
DO NOT use Oxygen to charge dampener. Use compressed
air or clean dry Nitrogen only.
DO NOT exceed maximum allowable working pressure
(MAWP) specified on dampener serial tag or marked on
dampener.
Turn pump off and remove all pressure from system prior to
dampener installation.
Always wear safety glasses and other appropriate safety
equipment when installing, charging or repairing dampener.
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 inline 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 are intended for use in potentially explosive atmospheres and meet the requirements of
ATEX directive 2014/34/EU. These models have the AT designation at the end of the part number, comply with ISO 80079-36, and have
an ATEX rating of II 2GD Ex h IIB T4 Gb Db. 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 no need for lubrication with bladders or bellows.
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 reassembly with fasteners of equal grade/strength value� DO NOT reuse 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 disassembly, use new fasteners and torque fasteners according to specification on dampener tag. If
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.
BLACOH Industries
Danger of static spark! Grounding precautions must be
considered when dampener is used in flammable or explosive
environments.
ATEX models must be grounded (earthed) before operation.
DO NOT operate a dampener that is leaking, damaged,
corroded or otherwise unable to contain internal fluid, air or gas
pressure.
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.
