Scheduled maintenance intervals
To ensure that your agitator operates ef
ficiently, it is essential to follow a simple preventive maintenance programme, 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 agitators.
However, you will appreciate that a machine, which is subject to rough and dirty conditions, will need more frequent attention
than one working in ideal conditions. We trust that you will adjust your maintenance programme to meet the demands of your
normal operating conditions.
