4.1 Replacing the hose
4.1.1 DISASSEMBLING THE HOSE
Close the inlet and discharge valves, purge the pipes.
Disconnect the pump from inlet and discharge piping.
If the pump is equipped with the "leak detection kit",
which allows the pump to be stopped in the event of the
hose breaking, first the capacitive sensor must be removed
by unscrewing the large PVC ring. See the kit Instructions
for further information.
Drain the lubricant by unscrewing the level plug
33
and
collect the lubricant in a tub.
Put the lubricant level plug
33
back in place.
Retighten cover screws
33
until they make contact.
Free the space as required and explained in § PUMP
LOCATION.
Remove circlips
24
from the suction and discharge
ports.
Loosen and remove screws
48
with their washers
49
and remove brackets
18
from the suction and discharge
ports.
Loosen inlet and discharge clamps
7
and
9
.
Remove the 2 inserts
12.
Place a tub under the lower port so that the lubricant in
the pump is collected.
NOTES
To insure an optimal life cycle of the hose, it is recom-
mended to replace the worn lubricant by some new
lubricant during any replacement of hose.
The hose may contain a certain volume of the pumped
fluid, but this will be expelled when restarting the pump.
Evacuation of this fluid may also be carried out by run-
ning the pump after having taken all the safety measu-
res required for personal and property protection.
If maintenance of the pump is not carried on site, check
the wheel rotation direction to determine the inlet and
discharge ends.
