Assembly/Disassembly
No pump assembly operations are envisaged.
During the disassembly phase ensure the tank is empty.
Disconnect the electrical parts.
Where the machine is to be scrapped, do not dispose of potentially polluting parts in the environment, following
local regulations for their correct disposal.
At the time of the machine being scrapped it is necessary to remove and destroy the identification plate and all other
relative documents.
3.4.1
Disassembling the cover
Pumps Part N° 888100 and 888120
Screw a 3 mm screw into the hole of the nylon tube which secures the cover to the tank and, taking the head
of the screw with a pair of pliers, completely extract the nylon tube from its seating and remove the cover.
Pump Part N° 888110
This pump is equipped with a pressure disk with a seal which remains perfectly in contact with the internal
surface of the tank. When the pressure disk, following the level of the grease being pumped, descends down
the guide rod, an increase in pressure is created in the zone above the disk itself. After having removed the
nylon tube as described above, it is necessary to raise the cover and at the same time tilt it until the passage
of air is permitted eliminating the existing difference in pressure between the zones above and below the
pressure disk.
3.4.2
Removing the tank
Where it is necessary to remove the tank to clean or replace the pump, remove the nylon tube which secures
the tank to pump body as described for removing the cover.
3.5
Regulation
Pressure
It is possible to regulate the working pressure by inserting a regulating valve (Part No. 0888036) in the delivery line.
Pressure regulation: 0 - 25 MPa (0 - 250 bar).
3.6
Maintenance
Locate the machine in conditions which facilitate easy access.
!
Utilise individual protection to avoid contact with mineral oil or grease.
Periodic inspection
Periodically it is necessary to check:
VERIFICATION
The state of lubrication
The oil level
Cleanliness of the filling and intake filter (where
fitted)
Clean the tank of any deposits on the bottom
The tank should only be filled with clean lubricant free from metallic particles or foreign bodies in order to ensure
the long life of the pump and to avoid damage to the machine being lubricated.
The machine does not require any special tools to carry out checks or maintenance tasks, However, it is
recommended that only tools suitable for the tasks and in good condition should be utilised (DPR 547/55) to avoid
injury to persons or damage to machine parts
