WARNING!
Ensure that the pulsation damper iseasily accessible at all times for opera‐tion and maintenance. Do not obstructor block access routes.
CAUTION!
– Carefully read the operatinginstructions before commencinginstallation and commissioning.
– Install the pulsation dampers inaccordance with the applicableregulations (for example governingpressurised vessels).
– First check whether the pulsationdamper matches the strokevolume of the metering pump.
– The pulsation damper can stillcontain residual water followingtesting. Drain water out of the pul‐sation dampers or flush them witha suitable medium if you are usingfeed chemicals, which may notcome into contact with water.
– Never use the pulsation damperswith media which could corrodetheir materials.
– Protect the pulsation damper fromdirect sunlight and other sourcesof UV.
– Preferably install the pulsationdamper as close as possible to themetering pump.
– Pulsation dampers only workeffectively with a specific stableback pressure. Therefore install aback pressure valve or an injectionvalve with low or fluctuating backpressure.
– Provide a connecting option for amanometer close to the pulsationdamper to check the pressure con‐ditions in the pipe system.
– Install a shut-off valve and ableeder valve to depressurise thepulsation damper to atmosphericpressure.
– Insert the bleeder valve into thestorage tank or another suitablevented vessel.

– Install a relief valve to protect thepulsation damper from rupturing inthe event of a fault.
– Avoid oscillations. Fix the pulsa‐tion damper firmly in place usingthe wall bracket.
– Connect the pipelines to the pulsa‐tion damper so that no forces actbetween them, e.g. caused byshifting, weight or expansion of theline.
– The connector size of the pulsa‐tion damper should preferablymatch the connector of the pipe‐work. At most they may vary by anominal width.
Keep a suitable union nut to hand for connec‐tion.
Lay the metering line straight with the connec‐tion nominal width of the pulsation damper toavoid unnecessary loss of output.
1. Screw the wall bracket to a stable basesurface, remembering the washers.
2. Fit the pulsation damper onto themetering line.
3. Fix the pulsation damper in place withthe wall bracket. Make sure that the pul‐sation damper and pipes do not oscil‐late.

5 Start Up
CAUTION!
Note the national regulations whenstarting up the pulsation damper.
In Germany, for example, the operatormust currently ensure that pulsationdampers with a volume of 5 litrescomply with the national regulation inaccordance with EN 2014/38/EU. Fur‐thermore the operator must ensure thatthe pulsation damper undergoes ahandover inspection by an expert inaccordance with @TRB 531 (TechnicalRegulations Governing PressurisedTanks) and the national directive inaccordance with EN 2014/38/EU at theinstallation site (arrangement inspec‐tion, equipment inspection, installationinspection and handover inspectioncertification).
CAUTION!
A manufacturer’s declaration should beissued for pulsation dampers with avolume of 5 litres.
CAUTION!
Check correct installation in accord‐ance with the installation instructions.
CAUTION!
Take appropriate protective measures ifhazardous feed chemicals are beingmetered – refer to the material safetydata sheet for the feed chemical.
1. Check the installation. (Is the relief valvecorrectly adjusted?)
2. Close the shut-off devices on the dis‐charge side.
3. Increase the charging pressure of thebladder to 40% charging pressure usingthe bleed valve (based on the operatingpressure of the feed chemical).
4. Open the shut-off devices on the dis‐charge side.
5. Start up the metering pump at a lowcapacity.
6. Monitor whether the threaded connec‐tors and the pulsation damper’s bleedvalve are air-tight.
7. Slowly increase the capacity to therequired value.
8. Increase the charging pressure to 60 ..80%.
9. Check whether the pressure of thebladder remains constant.
10. Check whether all hydraulic componentsof the system are tight.

6 Maintenance and RepairSafety information
CAUTION!
Wear suitable protective equipmentwhen metering hazardous or unknownfeed chemicals. Adhere to the materialsafety data sheet for the feed chemical.
CAUTION!
Bleed the pulsation damper at regularintervals! They can rupture or flythrough the room with too low a gascushion.
Maintenance intervals
Maintain at regular intervals, depending on thefeed chemical, installation and operating condi‐tions.
Check the following regularly
n The tightness of the threaded connectorsand wall brackets, if fitted
n The leak-tightness of the pulsation damper(welding seams and adhesive)
n Vapour effect of the manometer close tothe pulsation damper
Repair
Ensure that the bladder and pulsationdamper are at atmospheric pressure.Drain the pulsation damper and, if nec‐essary, flush with a neutral medium.Adhere to the material safety datasheets for the feed chemical!
Replacing the bladder:
1. Disconnect the pulsation damper fromthe system, with regard to pressure.
2. Depressurise the bladder via the airvalve: to do so, remove the rubber cap,unscrew the valve cap and press thevalve cap onto the tapper in the centreof the valve.
3. Bring the pulsation damper to atmos‐pheric pressure via a bleeder valve inthe system.
4. Remove the pulsation damper.
5. Drain the pulsation damper and, if nec‐essary, flush it through with a neutralmedium.
6. Loosen the hexagonal head screw onthe pulsation damper.
7. Remove the old bladder.
8. Ensure that all sealing surfaces areclean and smooth, including the sealingsurface of the new bladder.
9. Reassemble the pulsation damper inreverse order.
10. Re-tighten the hexagonal head screws.
11. Re-install the pulsation damper in itscorrect position.
12. Start up the pulsation damper again -refer to the "Start Up” chapter.

12 Calculations Principles for Design VolumeWith simple metering pumps:
Estimation of the design volume V0 in l for residual pulsation of approx. ±5%:
V0 = 0.8 * F * C * VH
with
V0 - Design volume
F - Factor for pump construction - see Ä „Table 1: Factor F for pump construction“ on page 21
C - Conversion factor - see Ä „Table 2: Conversion factor C“ on page 21
VH - Stroke volume (l/stroke = 0.001 * ml/stroke) with mean operating pressure - refer to thepump’s performance data
Table 1: Factor F for pump construction

Example:
Output data
Pump type: Meta HM 10-530,
Pump construction, 1-cylinder metering pump
System pressure Pm: 1.5 bar
Stroke volume 61.34 ml/stroke or 0.06134 l/stroke
Therefore:
F = 26 (for 1-cylinder metering pumps (see Ä „Table 1: Factor F for pumpconstruction“ on page 21))
C = 1.43 (for 1.1 * Pm = 1.5 (see Ä „Table 2: Conversion factorC“ on page 21))
V0 = 0.8 * C * F * VH =
0.8 * 1.43 * 26 * 0.06134 =
1.907 l
Therefore select a pulsation damper with V = 2.5 l.
