Cap.
- Introduce the sponge at the beginning of the section to be washed, being careful to restore pipe blocking through gaskets and
joints.
Take all the necessary safety measures to avoid sponge ejecting from the piping section causing injuries to
near-by persons and/or damages to objects.
Carefully read the relative paragraph to eliminate clogging during cleaning.
-
Cleaning with water
- Wet a washing sponge with water (FIG.29-REF.1) and insert it in the piping.
- Re-connect piping to the machine and open the shutter, if present.
- By means of Victaulic fittings complete with rubber gasket, connect the specific drum (FIG.29-REF.2) collecting the outfeed
sponge at piping end.
- Fill the hopper with water and start pumping.

FIG.29
The exiting of the sponge from the end pipe is violent: adequately direct the end pipe so no one near-by is
injured and/or property damaged. If deposit is present inside the piping, the sponge does not exit: reverse the
pumping direction to drain pressure inside the piping and stop the machine.
Carefully read paragraph 7.7 to eliminate any deposit during cleaning.
- Water-suction
cleaning
Insert the rubber sponge at the end of the end pipe, activate pumping by means of leverl 4 (FIG.27) and hold the lever
downwards, if pumping is vertical. The concrete is sucked back in hopper.
The concrete may outflow from the hopper if piping is long.
7.8 IMPORTANT
WARNINGS
The operator must be specifically trained to following the operations below. Ensure there is no residue pressure
in the piping and no other persons are near-by, before opning a joint. This, potentially dangerous, operation
must always be carried out, with the utmost caution, by an experienced person.
The manometer (FIG.28-REF.5) shows pressure higher than 150 bar and pumping blocks in case of clogging.
Reverse pumping cycle and run 4-8 suction cycles: the hopper content level will increase.
Clogging can now be eliminated.
