3.4 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 WORK 

CYCLE 

The state of lubrication 

1000 

The oil level 

2000 

Cleanliness of the filling and intake filter (where 
fitted) 

2500 

Clean the tank of any deposits on the bottom 

3000 

 
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
