Maintenance Actions
Maintenance may be seen as the totality of all scheduled and
unscheduled maintenance work.
Maintenance includes:
1. SCHEDULED MAINTENANCE : Maintaining the nominal state of
operation.
2. UNSCHEDULED MAINTENANCE : Restoring the nominal state
of operation
NOTE
The frequency with which repairs are performed depends on the process and
presence of substances that shorten pump life (dust, abrasives, solvents, water,
chemically aggressive substances).
The pump must be cleaned at regular intervals of time.
CAUTION!
Do not clean with Alcohol the plastic or rubber components of the pump.
Use only the strictly necessary amount of lubricant; an excess of
lubricating oil, like when there is none, may sometimes compromise
proper operation of the pump.
Only the recommended lubricants, or lubricating oils with similar
characteristics and known and experimented quality, should be used.
Oil changes must be made with the oil at a sufficiently high
temperature, after leaving the pump to cool for a few minutes
following operation.
The drain and filler plugs must not be left open any longer than is
strictly necessary.
When performing maintenance, look out for all signals that may
precede a breakdown, in particular:
ƒ traces of corrosion;
