NOTICE :
Seals are designed for use in normal conditions
intended for use in food process. In order to
assure a perfect sealing on SLC series pumps
we recommend to :
•
do an inspection of the seals every three months
(this time could be shorter if using the pump in
hard conditions. Contact the manufacture for
advice if necessary).
•
replace the pump sealing every two years
(refer to the § PROTECTION OF THE BELLOWS
for the replacement of the second seal).
It is important to keep a good grip on the piston ;
its rotation could lead to deterioration of the bellows.
BE CAREFUL WITH THE WEIGHT OF
THE PARTS WHEN THEY ARE BEING
REMOVED.
WARNING
The weight ot the parts can
be dangerous and may
provoke bodily injuries or
material damages.
