Maintenance frequency
Back-up ball bearings
When the pump is running, the rotor is levitated magnetically. There
is therefore no friction between moving and fixed parts.
The rotor remains levitated by magnetic ball bearings.
Only the back-up ball bearings require maintenance: they are
designed to withstand many accidental shut-downs, or many
landings of the rotor on the ball bearings at full speed.
These accidental shut-downs occur only in exceptional circumstances:
broken power supply cable, strong shocks, faulty electronics. It is
advisable to check the bearing counter and provide ball bearing
maintenance, when needed.
Back-up ball bearings are designed to withstand abnormal landings
at full speed.
The wear of the back-up ball bearings is internally monitored by the
controller, based on the rotation speed and the landing duration.
Initial percentage value is set at 100%. When this percentage
reaches 0%, an alarm is generated, pump can’t restart, and back-up
ball bearings need to be replaced by authorised Service Center.

Warning messages for
pumps maintenance
The ball bearing alert threshold can be set on the menu
(
C300
).
The internal memory of the controller also informs the operator
when the ball-bearings require maintenance
(
D200
).
The life time of the rotor is at least 5 years under normal conditions with
clean process. Please contact the Service Center to check your application.
The full overhaul must be performed by manufacturer’s trained personnel.
Only inlet screen, coil or pump valve replacement are authorized at the
customer’s site.
