General notes
A suitable maintenance is important for a longer duration of the equipment in good working condi-
tions and efficiency ensuring functional safety as time goes by.
All maintenance operations must be carried out by a qualified staff. The pump design and the mate-
rials used to manufacture it limit the maintenance interventions to a simple periodic cleaning.
The staff must be provided with the individual protections that are generally used for similar opera-
tions. They also must follow the safety rules described in section 6.2.
6.2

Disassemble and clean the delivery and suction filters as well as the fluid passage ducts.
working hours
Note: If highly pigmented paints or paints with many particles tending to deposit are used, carry out
maintenance operations at shorter intervals.
Every 2000
Overhaul the whole painting unit and replace the worn components.
working hours
The component corrosion speed varies according to the type of paint and the working conditions. To
replace the worn components, follow the given instructions.
6.4
