Lubrication
The pump’s lubricating system is force-feed type.
Oil circulation is obtained by means of a gear pump connected to the
rotor shaft.
The oil is drawn through a gauze filter to prevent any foreign bodies
from entering the pump.
Shunt-mounted on the delivery line is a hydraulic piston which,
besides actuating the anti-suckback device (see ANTI-SUCKBACK
DEVICE), also regulates pressure by discharging excess oil flow
directly into the tank.
The required flow of oil under pressure passes through ducts that are
drilled in the walls of the pump and lubricates the bushings and the
inside parts.
