READ CAREFULLY THE FOLLOWING WARNINGS BEFORE PROCEEDING
TO INSTALL OR CARRY OUT MAINTENANCE ON THE PUMP.
WARNING: ALWAYS DISCONNECT THE POWER SUPPLY BEFORE PROCEEDING TO INSTALL OR CARRY OUT
MAINTENANCE ON THE PUMP.
WARNING: WE RECOMMEND INSTALLING THE PUMP IN A VERTICAL POSITION TO ENSURE PROPER OPERATION.
WARNING: PRODUCT INTENDED FOR PROFESSIONAL USE ONLY, BY QUALIFIED PERSONNEL.
WARNING: THE MAINTENANCE OF THE PUMP MUST BE CARRIED OUT BY QUALIFIED AND AUTHORIZED
PERSONNEL.
-H2SO4SULPHURIC ACID Before dosing chemicals that could react with water it is necessary to dry all the internal
hydraulic parts.
-The ambient temperature must not exceed 40°C. The relative humidity must be lower than 90%. The pump protection
class is IP65. Do not install the pump in a place where it would be in direct sunlight.
-Secure the pump firmly into place in order to avoid excessive vibrations.
-The power-supply voltage available in the system and the working pressure must be compatible with those indicated on the
pump label.
WIRING CONNECTIONS
Input A
Power supply 110 ÷
230Vac (50 Hz)
The pump should be connected to a power supply
complying with the indications shown on the label on
the pump side. Failure to comply with the limits
indicated may cause damage to the pump.
These pumps have been designed to absorb minor
over voltages However, in order to prevent any
damage to the pump it is always preferable to avoid
connecting it to the same source of power as electrical
equipment that generates high voltages.
The connection to the three-phase 380V line MUST
always be made solely between phase and
neutral. No connections should
be made between phase and earth.

Drilling template for the wall bracket
After about 800 hours of operation, tighten the bolts of the pump body by using a tightening torque of 3 Nm.
In making the hydraulic connections it is necessary to comply with the following instructions:
-The BOTTOM FILTER should be installed at a distance of about 5-10 cm from the bottom, in order to avoid clogging;
-The installation with the pump below the liquid level is recommended for pumps with very low flow rates. In particular when
dosing products that have a tendency to develop gases (ex: sodium hypochlorite, hydrazine, hydrogen peroxide...)
-If it is necessary to use tubes longer than those supplied with the installation kit, they must always have the same
dimensions as those supplied with the pump. If the DELIVERY PIPE is exposed to direct sunlight, it is recommended the
use of a black UV-resistant pipe;
-It is advisable for the INJECTION POINT to be placed higher than the pump or the tank.;
-The INJECTION VALVE supplied with the pump, should always be installed at the end of the dosing-flow delivery line.
STARTING UP THE PUMP
Once you have checked all the above operations, you are ready to start the pump.
Priming
-Start the pump
-Open the priming coupling by turning the knob anticlockwise and wait for the liquid to flow out of the hose connected to it.
-Once you are sure that the pump is completely filled with liquid you can close the coupling and the pump begins to dose.
TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE SOLUTION
The pump is running regularly but the
dosage was interrupted
The valves are clogged
Clean the valves or replace them if it’s not possible
to remove the deposits
Eccessive intake height
Position the pump or the tank so as to reduce the
intake height
The liquid is too viscous
Reduce the intake height or use a pump with a
higher flow rate
Insufficient flow rate
Leaky valves
Check the tightness of the nuts
The liquid is too viscous
Reduce the intake height or use a pump with a
higher flow rate
Partial clogging of the
valves
Clean the valves or replace them if it’s not possible
to remove the deposits
Irregular pump flow rate
Transparent PVC tube for
delivery
Use the opaque PE tube for delivery
The diaphragm is breaking
Excessive back pressure
Check the system pressure. Check if the injection
valve is clogged. Check if there is a clogging
between the discharge valves and the injection
point.
Operation without liquid
Check the presence of the foot filter (valve)
The diaphragm is not fixed
properly
If the diaphragm has been replaced, check its
proper tightening
The pump does not turn on
Insufficient power supply
Check if the values on the plate of the pump
correspond to those of the electrical network.

-H2SO4SCHEFELSÄURE Vor der Dosierung chemischer Produkte, die mit Wasser reagieren können, müssen alle
internen Komponenten der Hydraulik getrocknet werden.
-Umgebungstemperatur unter 40°C. Relative Luftfeuchte unter 90%. Schutzgrad: IP65 Die Pumpe nicht so installieren, dass
sie direkt Sonnenstrahlen ausgesetzt ist.
-Die Pumpe gut befestigen, damit übermäßige Vibrationen vermieden werden.
-Versorgungsspannung und -druck der Anlage müssen mit den Angaben auf dem Etikett der Pumpe übereinstimmen.
ELEKTRISCHE ANSCHLÜSSE
Eingang A = Versorgung
110 ÷ 230 Vac (50-60
Hz)
Die Pumpe muss an eine Versorgung
angeschlossen werden, die mit den
Angaben auf dem Etikett an der Seite der
Pumpe übereinstimmen. Die
Nichtbeachtung dieser Vorschrift kann zu
Schäden an der Pumpe führen.
Die Pumpen wurden geplant, um geringe
Überspannungen absorbieren zu können.
Um Schäden an der Pumpe zu vermeiden,
sollte daher immer sicher gestellt werden,
dass sie keine Energiequelle zusammen mit
anderen elektrischen Apparaten nutzt, die
hohe Spannungen erzeugen.
Die Verbindung mit der 380V-
Dreiphasenleitung darf NUR zwischen
Phase und Neutralleiter vorgenommen
werden. Die Anschlüsse DÜRFEN NICHT
zwischen Phase und Erde erfolgen.

Bohrschablonen Wandbügel
Nach etwa 800 Betriebsstunden die Bolzen des Pumpengehäuses mit einem Anzugsmoment von 3 Nm anziehen.
Zum Durchführen derWasseranschlüsse müssen folgende Hinweise beachtet werden:
-Den BODENFILTER etwa 5-10cm über dem Boden installieren, um eventuelle Ablagerungen zu vermeiden
-Die Installation unter dem Flüssigkeitsstand wird bei Pumpen mit sehr geringer Fördermenge empfohlen. Insbesondere für
die Dosierung von Produkten, die Gase entwickeln (z.B. Natriumhypochlorit, Hydrazin, Wasserstoffperoxid,...).
-Bei Schläuchen, die länger als die im Installationssatz enthaltenen sind, ist es wichtig, dass diese dieselben Maße wie die
mit der Pumpe gelieferten aufweisen. Wenn die DRUCKLEITUNG Sonnenstrahlung ausgesetzt ist, empfiehlt sich der
Einsatz eines schwarzen, UV-beständigen Schlauchs;
-Der EINSPRITZPUNKT sollte höher als die Pumpe oder der Tank liegen;
-Das EINSPRITZVENTIL, das mit der Pumpe geliefert wird, muss immer am Ende der Druckleitung des Dosierungsflusses
installiert werden.
START
Nach der Durchführung aller zuvor beschriebenen Schritte ist die Pumpe für den Start bereit.
Befüllen
-Die Pumpe starten
-Den Befüllanschluss durch Drehen des Knaufs entgegen dem Uhrzeigersinn öffnen und warten, bis die Flüssigkeit aus der
angeschlossenen Leitung tritt.
-Nachdem sicher gestellt wurde, dass die Pumpe ganz gefüllt ist, kann der Anschluss wieder geschlossen werden und die
Pumpe beginnt mit der Dosierung.
PROBLEMBEHEBUNG
Störung
Mögliche Ursache
Lösung
Die Pumpe funktioniert normal, aber die
Dosierung wurde unterbrochen.
Verstopfung der Ventile
Die Ventile reinigen oder, wenn es nicht möglich ist,
die Verkrustungen zu entfernen, ersetzen
Übermäßige Ansaughöhe
Die Pumpe oder den Tank so positionieren, dass die
Ansaughöhe reduziert wird
Flüssigkeit zu viskos
Die Ansaughöhe reduzieren oder eine Pumpe mit
höherer Fördermenge nutzen
Unzureichende Fördermenge
Leckage der Ventile
Kontrollieren, ob die Gewinderinge korrekt
angezogen sind
Flüssigkeit zu viskos
Eine Pumpe mit höherer Fördermenge nutzen oder
die Ansaughöhe reduzieren
Teilweise Verstopfung der
Ventile
Die Ventile reinigen oder, wenn es nicht möglich ist,
die Verkrustungen zu entfernen, ersetzen
Unregelmäßige Fördermenge der
Pumpe
Für die Druckleitung wird
ein transparenter PVC-
Schlauch genutzt
Einen undurchsichtigen PE-Schlauch für die
Druckleitung nutzen
Membran ist kaputt
Zu hoher Gegendruck
Den Druck der Anlage prüfen. Prüfen, ob das
Einspritzventil verstopft ist. Prüfen, ob zwischen den
Druckventilen und dem Einspritzpunkt
Verstopfungen vorhanden sind.
Betrieb ohne Flüssigkeit
Prüfen, ob der Bodenfilter (das Ventil) vorhanden
ist. Eine Füllstandssonde verwendet, die die Pumpe
blockiert, wenn das chemische Produkt im Tank zu
Ende geht
Membran nicht richtig
befestigt
Bei Ersatz der Membran prüfen, dass diese wieder
richtig befestigt wird.
Die Pumpe geht nicht an
Unzureichende Versorgung
Prüfen, ob die Werte auf dem Typenschild der
Pumpe mit denen des Stromnetzes
übereinstimmen.
