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.
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.
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.
