Water meter
Model MAGDOS FL(S) can be addressed by
commercialcontactwatermeters.Inordertoavoid
disturbing influences or faulty pulses, the pump
shouldnotbemounteddirectlytothewatercounter.
However,ifanadapterisusedprovidingforadistance
of50mmadirectmountingisallowed.Preferablythe
pumpshouldbemountedtothechemicaltankorto
awallholder.The electronicsystemisdesignedfor
a maximum input frequency of 105 contacts per
minute. The pulse sequence of the water meter
shouldbedesignedaccordingly.
General
In many processes in water and waste water
treatment as well as in swimming pools metering
pumpsarerequiredwhichcanbeadaptedprecisely
to the corresponding process and the necessary
functions regarding their metering capacity. Mete-
ring pumps of the MAGDOS E/EL/FL series were
designed such that you can select the appropriate
pump for each specific task.

Pumps of the EL and FL series are optionally also
available with a fault indicator relay (type ELS and
FLS) for a remote alarm signal if the level of the
metering medium is too low or in the case of power
failure.

Operating and Maintenance Instructions

probesandcontainmenttanks.
Meteringpumpsareproducedaccordingtohighest
quality standards and have a long service life.
Nevertheless some parts are subject to wear (e.g
diaphragm,valveseats,valveballs).Toensurelong
operating life, visual checks are required regularly.
Operatingandmaintenancepersonnelmustbeable
to access the pump easily. Periodic maintenance
protectsthe metering pumpagainstshutdowns.
Toincreasethemeteringaccuracyandreliability,we
recommendusingadditionalfittings.Theseinclude

andchemicallowlevelindicators,asshowninfigures
1 to 3.
Always use appropriate tools for the installation of
plastic connecting parts. In order to avoid damage,
neverapplyexcessiveforce;plasticparts(especially
PVC parts) can be screwed and unscrewed more
easily if the thread is lubricated with vaseline or
siliconegreasebefore.
Note: For this purpose, the compatibility with the
chemical to be metered must be checked.
MAGDOS metering pumps with integrated level
controlfunctionareequippedwithashort-circuitjack
plug which must be removed before connecting a
level control by means of a jack plug. To keep the
protection class, screw a PG plastic sleeve on the
jackplug.TherequiredPGsleeveispartofthelevel
control (also in combination with a suction line).
Mounting the metering pump directly on the water
metermay result in noise levelamplification.Inthis
case, it is recommended to mount the pump on
separatewall brackets which,forthe same reason,
shouldbefixedtoouterwallsinsteadofinteriorwalls
with adjacent occupied rooms. It is also possible to
mount the pump directly on the metering supply
tank.
Ambient temperatures exceeding 40°C are not
permitted. Radiant heat of apparatus and heat
exchangersmustbekeptinlimitsallowingthepump
to sufficiently dissipate its own heat. Exposure to
directsunlightshouldbeavoidedespeciallyformete-
ringpumpswithplastichousingsbecausetheblack
plastic material can be damaged. If the pump is
installed outside, provide an enclosure to protect it
againstweather.
Wiring of the MAGDOS metering pump must be
carried out by a specialist according to the local
regulations. Normally the MAGDOS is connected
withasafetyplug.TheelectricaldataforallMAGDOS
data is listed in Table 14 "Technical data".
Note:TheMAGDOSmeteringpumpsarenotsuited
to be used in explosive environments.

3. Installation
Forselectionofapumpduringconstructionofaplant
as well as for installation and operation, the local
rulesmustbeobserved.Thisappliestotheselection
of suitable pump materials, the handling of the
chemicals and the electrical installation. At the
same time the technical data of the metering pump
according to table 12 must be considered, and the
plantmustbedesignedcorrespondingly(e.g.pressure
loss in lines depending on nominal diameter and
length).
Both, the designer and the user are responsible to
make sure that the whole plant including the mete-
ring pump is constructed so that neither plant
equipmentnorbuildingsareseverelydamagedinthe
case of chemical leakage due to the failure of wear
parts(e.g.diaphragmrupture)orbursttubing.When
constructing chemical plants, the installation must
be carried out so that no consequential damages
appear which are unreasonably high even if the

5. Safety instructions
⇒
Whenworkingonchemicalequipment, observe
thelocalsafetyrules(e.g.wearpersonalprotective
clothes).
⇒ Beforeworkingonthemeteringpumpandplant,
disconnectitfromthemainpowersupplyandsecure
itagainstreconnection.Beforethevoltagesupplyis
switched on again, the metering lines must be
connectedsothatchemicalleftinthemeteringhead
cannot spurt out.
⇒The metering head of the pump as well as
connections and lines in the plant may be under
pressure. Working on the metering plant requires
specialsafetyprecautions and may only be carried
out by instructed technical personnel.
⇒ Beforestartup,allscrewedconnectionsmustbe
checked for correct tightness and, if necessary,
must be tightened up using appropriate tools.
⇒If connections at the metering head are
unscrewed during operation for venting or other
reasons, leaking chemical must be removed
completely.Thisistheonlywaytoavoidthedanger
of physical injury and corrosion at the metering
pump. Leaking chemical may also destroy the
diaphragm at its mounting points.
⇒ Whenchangingthechemical,checkwhetherthe
materialsusedforthemeteringpumpandtheother
plant parts are chemically resistant.
Ifthereisthedangerofachemicalreactionbetween
different media, a thorough cleaning first is
mandatory.
⇒Afteradjustmentworkatthecontrolpanelofthe
MAGDOS, the control cover must be closed again
(the cover is not available for all MAGDOS types).
Otherwise protection class IP 65 cannot be
guaranteed.
⇒After changing the electrical connections, e.g.
removing the level control, the PG cable gland nut
must be tightened in order to ensure the protection
class of the pump.

ATTENTION!
Leakage must be discharged
into a collection funnel using
a short inclining drain pipe
(and can then be returned to
the chemical tank).
The outlet of the drain pipe
must be visible in order to
actually see the leakage.
