Oil and fluid grease centralised lubrication systems
AZETA, founded in 1972, specializes in precision components for hydraulic and pneumatic applications. The company expanded into truck lubrication components in 1976 and centralized lubrication systems in 1994. Known for high-quality Italian-designed lubrication systems, AZETA offers manual, electric, pneumatic, and gear pumps.
Lubrication reduces friction, temperature, and noise in machinery using oils, greases, or other substances that form protective films on surfaces.
- Low Pressure Lubrication: Operates at 2-3 bar, suitable for small to medium machines, recommended for high-precision tools like lathes and grinding machines.
- Medium Pressure Lubrication: Operates at 20-40 bar, using oil or fluid grease.
- Air-Oil Minimal Lubrication: Uses minimal oil mixed with air, ideal for high-speed bearings and linear guides.
These systems use resistive dosing valves, ideal for precision machinery, and include manual and electric-cyclic volumetric pumps and magnetic vibration pumps.
Consider the number of parts to lubricate, required lubricant quantity, and distances between components. The flow rate of dosing valves should match the pump's flow rate for optimal performance.

Dear reader This manual describes the AZETA line of products and we would firstly like to provide you with a short company profile. AZETA came into being in 1972 as a manufacturer of precision turned mechanical parts and finished components for hydraulic and pneumatic applications, drawing on the experience accumulated since 1967 by its founder Zeo Asioli. In 1976 production began of components for truck lubrication. In 1986 took over Gi-Erre Impianti di Lubrificazione Autotrazione. In 1994 began production of an innovative line of low and medium pressure centralised lubrication systems at its...

PRODUCT RANGE LUBRICATION Lubrication is one of the most important aspects of tribology (from the Greek tribos = rubbing), defined as “the science and technique of surfaces working between themselves with relative motion.” Lubricants are substances in different physical states and of different nature, from hydrocarbons to inorganic substances and they can act under different conditions by the sliding of fluid, semisolid or solid layers to cause the formation of thin surface films for physical adhesion or chemical reaction between additives contained in the lubricant and the surfaces to lubricate....

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...

When choosing the components necessary to make the lubrication system most suited to one’s needs, it is wise to observe a few rules. Firstly, it is important to define the total number of mechanical parts to lubricate and the necessary quantity of lubricant for each point. This quantity is calculated by multiplying the surface to lubricate by the required thickness of oil. Afterwards it will be necessary to check the distances of the various parts to lubricate, in order to make a wellbalanced lubrication line in the distances of the various sets of dosing valves from the pump. Before choosing...

VOLUMETRIC MANUAL HYDRAULIC DIAGRAM DESCRIPTION Volumetric manual pump; each activation tallies with the pre-set quantity of lubricant. The lubricant is delivered by a plunger piston driven by a mechanical spring, suitably sized and preloaded. The volumetric flow rate is adjustable by a Benzing at the end of the plunger piston (see Part.1). OPERATION Operation takes place by using the ball grip to manually lift the plunger piston that in its turn fills the volumetric chamber with oil. On releasing the lifting ball grip the piston is freed and begins its descent pushed down by the compression...
