Lubrication is defined as low pressure when an operating pressure of 2-3 bar is sufficient to allow oil to reach the moving surfaces. It is suitable for lubricating small and medium sized machines and is obtained with simple, compact, economic systems. Low pressure lubrication is particularly recommended for high precision machine tools (such as grinding and boring machines, lathes, etc.) in which lubrication must not alter the stability of the machine's slides and screws. The moving parts must be suitably prepared (see paragraph with diagrams and applications). The AZETA line includes manual and electric-cyclic volumetric pumps as well as vibration pumps.
