pump. Never operate the pump in the wrong rotation as the pump will not function properly and
will likely result in damage. If rotation is incorrect for your system, contact an authorized
service center.
6. OIL LUBRICATION AND CONTROL SYSTEM
The vacuum pumps Farid Moro are designed with two different types of lubrication systems.
(see Figure 3).
6.1 FORCED LUBRICATION WITH GEARS.
The system is lubricated both in the vacuum and pressure functions by means of a gear pump
in the rear area, driven by the rotor shaft. The gear pump pulls the oil from the tank and delivers
it to the manually adjustable oil valve. Excess oil returns to the tank by means of a tube
connected to the oil valve. Forced lubrication is available, as standard in Europe, on all models
series AIR.
6.2 AUTOMATIC LUBRICATION.
With this system, lubrication is performed in both vacuum and pressure functions by means of
an adjustable flow rate dosing pump in the rear, driven by the rotor. The oil is directly injected in
the pump housing, avoiding manual regulation and achieving a significant saving of oil.
Automatic lubrication is standard on all U.S. AIR series pumps.
6.3 OIL TO BE USED.
The vacuum pump is delivered without lubrication oil inside the oil tank and gearbox (if any).
Pour mineral lubrication oil type ISO VG 100 (International symbol) in the oil tank and ISO VG
460 (International symbol) in the drive side gearbox (if used).
Never use hydraulic or detergent oil.

OIL LEVEL:
For internal lubrication, the min. and max. level of oil are indicated by marks located on the
stem of the dipstick (see Figure 4) located on the manifold.
