8.3. Dismantling the pump
OFF
For disassembly and reassembly, refer to the cross-
section drawing (paragraph 12.2 Annexes).
The pump function can be impaired by erroneous
procedure or tampering with internal parts.
To inspect the impeller (28.00), to clean the internal
parts and to check whether the impeller turns freely
when moved by hand, remove the screws 15.70 or
strainer 15.50, the screws (14.24) pump casing (14.00).
To dismantle the impeller remove the nut (28.04).
Others parts should not be dismantled.
8.4. Mechanical seal inspection
If the mechanical seal (36.00) and the oil chamber are
to be inspected, follow these instructions.
CAUTION: there may be slight pressure in
the oil chamber.
Care must be taken to avoid a sudden spurting
of oil.
Once the plug (34.08) with washer have been removed,
adjust the hole to the downward position and empty the
chamber completely.
Do not dispose of the waste oil in the enviroment.
The mechanical seal (36.00) can be inspected by
removing the screws (70.18).
When re-filling with fresh oil, remember that the
chamber must not be completely filled; a sufficient
quantity of air must remain inside it in order to
compensate for overpressure caused by thermic
dilation of the oil.
The quantity of oil to be inserted in the chamber is:
0,04 litres.
Use white oil suitable for food machinery and
pharmaceutic use.
