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. It is necessary to use resistive dosing valves as well as new and clean oil.
PRODUCTS
LOW PRESSURE
volumetric manual
PM 13 e PM 26
Tank capacity:
0,6 liters
Adjustable flow rate:
from 1 to 3 cm3 (PM 13)
from 2 to 6 cm3 (PM 26)
Sizes:
85 x 72 x 175-202h (PM 13)
85 x 72 x 173-203h (PM 26)
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.

132 x 99 x 173-203h (PM 26.L)
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.
electric-cyclic
PE 13
Tank capacity:
1,2 liters
Adjustable flow rate:
from 1 to 3 cm3
Sizes:
132 x 99 x 228-255h
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.
PE 26
Tank capacity:
1,2 liters
Adjustable flow rate:
from 2 to 6 cm3
Sizes:
132 x 99 x 228-255h

PE 26 R3
Tank capacity:
3 liters
Adjustable flow rate:
from 2 to 6 cm3
Sizes:
215 x 145 x 205-235h
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.
Vibration magnetic
PV 140
Tank capacity:
1,2 liters
Max flow rate:
from 70 to 140 cm3/min
according to the lubricant viscosity
Sizes:
132 x 99 x 196h
Continuous operation low-pressure vibration magnetic pump, whose speed is the same as the frequency of the electric mains (50/60 Hz). The lubricant gets delivered by the magnetic core that acts as a piston; the working pressure, set to 3 bar is controlled by a By-pass valve to recover and return any excess lubricant to the reservoir.
PV 140 R3
Tank capacity:
3 liters
Max flow rate:
from 70 a 140 cm3/min
according to the lubricant viscosity
Sizes:
215 x 145 x 220h
Continuous operation low-pressure vibration magnetic pump, whose speed is the same as the frequency of the electric mains (50/60 Hz). The lubricant gets delivered by the magnetic core that acts as a piston; the working pressure, set to 3 bar is controlled by a By-pass valve to recover and return any excess lubricant to the reservoir.
