The pump was started while still rotating in
the opposite direction, for a previous start
OVERHEATING OF EXTERNAL BEARINGS (bare shaft versions)
Lack of oil or wrong type of oil in the bearing
frame.
Excessive oil temperature into the bearing
frame.
PERIODIC AND EXTRAORDINARY MAINTENANCE
Proper maintenance and use are essential factors to ensure the functionality and pump lifetime
Cleaning components and magnet
To clean all surfaces of the couplings and centering surfaces, use possibly methyl alcohol. Use paper towels
instead. Do not use solvents and other corrosive liquids on magnet to avoid damaging it; any dirt can be
removed from the magnets by using gummed paper. Do not hack or put pressure on the magnet during its
handling, it would cause them, damages because of their fragility.
Periodic preventive maintenance
Instructions relating to maintenance activities whose implementation do not require specific skills that can then
be made by users of the pump, are given. They are operations and inspections planned on issues considered
important for technical, operational and security staff, determined on the basis of the knowledge gained from
PUMPS
. If the hydraulic pump is washed with jet in pressure, prevent the entry of water into the terminal of the

motor
DANGER
Do not throw water on the pump hot components: components can explode in case of
sudden cooling generating projection of metallic material and leakage of hot fluid in
pressure and hazardous to health. Do not give strokes and pressures on the bearings, you
would cause the formation of micro-cracks which can cause serious damages

Stop immediately the pump and drain all the liquid from the

discharge line before restarting.
Check the oil level: fill up or empty, and replace it if
necessary. Replace the bearings.
Fill the bearing frame with oil ras indicated in the
paragraph to restore the correct working temperatures
Warnings and protective
measures be taken to perform
the maintenance properly and
Top up the oil until the middle of the
eye plug
Check the status of bushings, sleeve
bearings and thrust bearings,
replace them if worn
Check the status of the wear ring,
consult the table of tolerances
