Automatic lubrication system

Automatic lubrication systems (ALS), occasionally called centralized lubrication systems (CLS), are devices that deliver controlled amounts of lubricant to multiple locations in a machine while it is operating. While these systems are usually fully automated, systems that require manual pump or button activation are still identified as centralized lubrication systems. These systems can be classified into two different categories. Oil systems that are primarily used for stationary equipment, such as CNC mills. Grease systems are primarily used on mobile equipment such as trucks, mining and construction equipment.

Not to be confused with Automatic lubricator.

Automatic lubrication systems are vital aspects of maintenance and reliability programs. They supply lube points with metered amounts of grease or oil from central locations. The pump provides the system with the chosen lubricant, fed from a reservoir that is easily accessible. Depending on the application, the reservoir ranges in size and can be as small as 2 liters up to an intermediate bulk container or a bulk tank. These systems can be monitored remotely and tied directly to control systems.
