11. MAINTENANCE

All maintenance that requires the pump to
be dismantled and reassembled should be
conducted by a specialised technician.
All maintenance should be conducted with the
pump disconnected from the power mains.
EN
Under normal operating conditions, the pump should be
serviced every 12 months (approximately every 2500 hours
of operation). If operating conditions are more severe, reduce
this interval to 6/8 months (approx. 2000 hours). To keep
pump performance unaltered over time, restore correct
impeller distancing plate (see para. 11.2) at each service.
Submit the pump for regular servicing according to the
table below.

11.1. Top-up/change of lubricant
Top-up or replace the lubricant using the hole on the plate,
placing the pump upside down (see Fig. 15.3.1). Ensure
that there is the quantity of lubricant stated in the table
15.3.2 in the oil chamber.
Use a non-foaming, non-detergent white mineral oil (CAS
8042475), suitable for coming into contact with food, such
as: VABRIOL ATOXOIL FU 15.
11.2. Adjustment of the distancing plate
(figs. from 15.1.1 to 15.1.2)
Adjust to the minimum possible:
- the distance between the impeller (1) and the diffuser
(2), by appropriately choosing the washer thickness
(3).

should be seen in the oil.
Replace each time they
are dismantled.
Replace every 3000 hours.
