6 Inspection and Maintenance
6.1 Replacement Interval of the Impeller
The impeller has a limited lifetime depending on the chemical type, concentration and temperature of the fluid
which is pumped. Therefore, a preventive periodical exchange of the impeller is recommended. Contact the
Levitronix
®
Technical Service Department (see Section 8) for further information on replacement times.

The following warnings and cautions should be read
carefully before starting the replacement of the
impeller.
The impeller could splash TOXIC or CORROSIVE
CHEMICALS because of the strong magnetic forces.
Flush the pump housing before opening it.
HARMFUL CHEMICALS may be present.
Skin contact and toxic gases may be hazardous to your
health. Wear safety gloves and other appropriate
safety equipment.
Pay attention to the magnetic forces when handling the
impeller. The attraction of magnetic parts and particles
should be avoided in order to keep the impeller and the
pump head clean and free of contamination.
