Preventive Maintenance
To ensure that your Alfa Laval LeviMag
®
operates efficiently, it is essential to follow a simple preventive maintenance program,
which will keep your machine in good working conditions. Good maintenance requires careful attention at regular intervals!
The following recommended preventive maintenance procedures are based on the average operating conditions of most
Alfa Laval machines. A mixer which is subject to abrasive fluids, will need more frequent attention than one working in ideal
conditions. The maintenance program should be adjusted to meet the demands of your normal operating condition.
Alfa Laval recommend that O-rings are replaced every 12
th
month.
Alfa Laval recommend that bearings are replaced every 20.000 operating hours.
NOTE
The gear can have a shorter live time than the mixer. Please pay special attention to the stated maintenance interval of the
gearbox.
