Back-up ball bearings
When the pump is running, the rotor is levitated magnetically. There
is therefore no friction between moving and fixed parts.
When the pump is stopped by the controller, the back-up ball
bearings are not used. 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.
The bearing counter
Warning messages for
pump maintenance
The ball bearing alert threshold can be set on the menu
(
C300
on the controller Operating instructions).
If the ball bearings life time is smaller than the alert threshold, an
alert message is displayed.
The troubleshooting is available in the controller Operating
instructions
(
D200).
The internal memory of the controller also informs the operator
when the ball-bearings require maintenance (refer to the controller
operating instructions).
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.
Product maintenance
The full overhaul must be performed by manufacturer’s trained personnel.
Only controller replacement, inlet screen or pump valve replacement are
authorized at the customer’s site.
