Progressive lubrication system

In a centralized lubrication installation with progressive distributors, a so-called progressive lubrication system, the individual lubrication points are supplied in a sequential and hierarchical order.
A progressive distributor or lubricant distributor supplies the lube points in a progressive order with lubricants.

The so-called lubrication time in a progressive lubrication system is identical to the pump running time, which is limited by the need to supply all lubrication points in the system once. During the break time, pressure is relieved in the main and secondary lines. The lubricant distributor in a progressive lubrication system consists of pipe (line) elements and progressive distributor elements. All components can be combined into one part.

This lubrication system is suitable for grease (NLGI class 2) and oils and can supply up to several hundred lubrication points. Application fields for the progressive lubrication system include punching industries, wood processing industries, etc.

The progressive lubricant distribution starts automatically after one cycle has supplied the last lubrication point. The obvious advantage of centralised lubrication with a progressive lubrication system is the relatively low investment costs.
This is due to the fact that only one main line, simple pumps and distributors are needed.

The progressive lubrication system is often found in more recent centralised lubrication installations for machinery and vehicles, because this lubrication technique for grease up to NLGI class 2 has not existed as long as the other systems.

Nevertheless, the progressive lubrication system has proved itself on the market and has already become standard in many application fields.
