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. This information is available on the name plate of your pump. Further information can be obtained online by
using the serial number.
Pr
eventive maintenance aims to prevent failure 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. It is advisable to install pressure gauges on both sides of the pump so that
any problems within the pump/pipework can be monitored.
