PREVENTIVE MAINTENANCE
For pump reliability and efficiency, comply with maintenance
intervals as shown in the table.
PREVENTIVE MAINTENANCE
Every 500 hours
Check oil level
To replace, follow instructions contained in the repair
*
manual.

PUMP STORAGE
12.1
Long-term inactivity
If the pump is started for the first time after a long
period from the date of shipment, before operation
check the oil level, inspect the valves as specified
in chapter 10, then follow described start-up
procedures.
12.2
Method for filling pump with anti-corrosion
emulsion or anti-freeze solution
Method for filling pump with anti-corrosion emulsion or
anti-freeze solution using an external diaphragm pump based
on the layout shown in par. 9.7 in Fig. 6 and Fig. 6/a:
•
In place of the service tank, use a suitable container
containing the solution to be pumped.
•
Close the filter drainage, if open.
•
Make sure that the hoses to be used are clean inside and
spread grease on their connections.
•
Connect the high pressure exhaust pipe to the pump.
•
Connect the suction pipe to the diaphragm pump.
•
Connect the suction pipe between the pump head and
the diaphragm pump.
•
Fill the service container with solution/emulsion.
•
Insert the free ends of the suction pipes and the high
pressure exhaust pipe inside the container.
•
Switch on the diaphragm pump.
•
Pump the emulsion until it exits from the high pressure
exhaust pipe.
•
Continue pumping for at least another minute.
•
Stop the pump and remove the previously connected
pipes.
•
Clean, grease and plug the connections on the pump
head.
The characteristics of the emulsion can be strengthened if
necessary by adding, for example, Shell Donax.

PRECAUTIONS AGAINST FROST
Follow the instructions in Chapter 12 in areas and
times of the year at risk of frost (see par. 12.2).
In the presence of ice, do not run the pump
for any reason until the circuit has been fully
defrosted, in order to avoid serious damage to
the pump.
WARRANTY CONDITIONS

1) improper use
2) failure to follow maintenance instructions
3) any use different from that described in the operating
instructions
4) lack of sufficient flow rate
5) defective installation

OPERATING FAULTS AND THEIR
POSSIBLE CAUSES
The pump does not produce any noise upon
start-up:
-
The pump is not primed and is running dry.
-
No suction water.
-
Valves are jammed.
-
The outlet line is closed and does not allow the
release of air present in the pump manifold.
Pump pulsates irregularly:
-
Air suction.
-
Insufficient supply.
-
Bends, elbows, fittings on the suction line are
choking the passage of liquid.
-
Suction filter is dirty or too small.
-
The booster pump, where installed, is supplying
insufficient pressure or flow rate.
-
The pump is not primed due to insufficient head
or the outlet is closed during priming.
-
The pump is not primed due to valve jamming.
-
Worn valves.
-
Worn pressure seals.
-
Imperfect functioning of the pressure control
valve.
-
Problems on the transmission.
