Periodic And Extraordinary Maintenance; Cleaning Components And Magnet; Periodic Preventive Maintenance - M Pumps SCE Series User Manual

Ball bearings or motor failure.
Uninsured motor or base plate
Misalignment or improper anchoring of the
pipes.
The pump was started while still rotating in
the opposite direction, for a previous start

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

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
