7.1. 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 pressu-
re in the oil chamber.
Care must be taken to avoid a sudden
spurting of oil.
For GQ.., GX...
Once the plug (34.08) with washer have been re-
moved, 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 (34.12).
For GM...
Once the plug (14.46) with washer (14.47) 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 impeller key (28.20), the screws
(14.24) and the pump casing (14.00).
When re-filling with fresh oil, remember that the
chamber must not be completely filled;
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:
0,08 litres for GQ.., GX...
0,5 litres for GM...
Use white oil suitable for food machinery and
pharmaceutic use.
For the GMC, GMV pumps a normal engine oil of
the SAE 10W-30 type can also be used.
