•
As soon as the liquid leaks, close the bleed valve (where present).
•
Carry out a visual and auditory check (for dripping or suspicious noises).
•
Check the piping is well supported, does not produce vibrations and, above all, does not exert
tensions on the pump head.
•
With 1)#!)#)#;)!#)!, adjust to 0% and leave the pump running in this condition for
at least minutes, this allows the pump to heat, which eliminates motor condensation. Then
progressively adjust the flow rate up to the flow rate value required by the process.
Inconveniences upon commissioning
=)!)!$1;")="''"()B#$=#)1
•
The features of the motor's electric power supply do not correspond to those on the plate or the
chosen connection is inadequate.
•
Check that the discharge pressure corresponds to that of the project.
=';!#)"1%;)=#)1"!
•
Incorrect pump flow rate adjustment: adjust the flow rate to the desired value.
•
Insufficient suction due to the excessive length of the piping or to a section that is too small. We
recommend replacing the piping with the necessary section or positioning the pump under the head
and as close as possible to the suction source.
•
The suction piping seal is not perfect (possible air infiltrations).
•
The liquid viscosity is not compatible with the pump version or the filter is clogged.
=';!#)"1#%F)=#)1"!
•
Siphoning phenomena occurs: check that the suction pressure is not higher than that of the
discharge pressure. Install a back pressure valve on the discharge circuit.
=';!#)"1F#!"#%
•
The problem may be due to solid particles coming from the piping or sediments in suspension
which prevent the perfect closure of the pump valves. Good cleaning and the installation of a filter
on the suction piping is recommended.
MAINTENANCE
Maintenance is a combination of all technical and administrative actions, including supervision, aimed at
maintaining or returning a machine to a condition in which it can perform the required function. (ref. UNI
10147)
List of spare parts
For proper, easy identification of spare parts, please refer to the drawings in the section attached to the
pump manual where notes are reported, which identify the components that are most subject to wear and
thus require more frequent maintenance. In their absence, request them from DOSEURO, referring to the
plate located on the pump to identify the model, serial number and year of manufacture.
The inspection and maintenance program depends on the conditions of use of the pump.
Good maintenance allows for the best possible performance, longer working duration and a
constant observance of the safety requirements.
