Inspect the pump regularly
The Alfa Laval pumps are available in various configurations to fit specific applications. To inspect the
pump you need to know the type of pump and which type of seal is used. This information is available
on the name plate of your pump. Further information can be obtained online by using the serial number.
Preventive maintenance aims to prevent failur
e of equipment by doing e.g. regular inspection and
lubrication.Based on experience and knowledge about the running conditions it is also possible to
replace wear parts before they fail. Keeping a maintenance log is a good way to build experience.

Scheduled maintenance intervals
T
o ensur
e that your pumps operate ef
ficiently, it is essential to follow a simple preventive maintenance programme, which will
keep your machine in good working condition. Good maintenance requires careful attention at regular intervals. For pump
lubrication please always refer to the manual for specific information on oil/grease types and required maintenance. Alfa Laval
recommend:
• Service kit should be replaced after 12 months. Always replace shaft seal and o-rings at the same time.
• Inspect motor bearings yearly, replace complete bearing if worn, ensure that the bearing is axially locked (See motor
instructions)
