Hose is blocked by mortar that is
too thick (high pressure by low
water factor)
Remove blockage, increase water

42 Conveyor stands still / clogging
Clogging might form in the conveying hoses for several reasons. This means that the material to be
conveyed remains stuck in the conveying hoses and cannot be pumped to the hose end.
42.1 Removal of clogging in hoses / signs for clogging
Implementation by operator:
Blockages can occur in the pressure flange or in the mortar hoses.
Indications are:
rapidly increasing conveying pressure,
blocking of pump,
running difficulties or blockage of the pump motor,
expansion and turning of the mortar hose,
no material discharge at the hose end.
42.2 Causes for clogging:
Highly worn mortar hoses,
work interruptions,
badly lubricated mortar hoses,
residual water in mortar hose,
clogging of the pressure flange,
strong tapering at the couplings,
kink in mortar hose,
badly pumpable and demixed materials.
