8. Water pump
The scrubbing/suction tool and the spray tool are options which can be installed in the
machine and then have to be activated in the machine control unit.
The spray tool requires a greater quantity of water so that a sufficient jet of water
comes out of the spray nozzle. In order to do this, the water pump is actuated with a
high voltage in order to obtain a sufficient delivery quantity. This can lead to the
system pressure increasing so much that the solenoid valve is opened by the water
pressure. To prevent this, a bypass must be installed between the water pump outlet
and the inlet which contains a valve which opens at a pressure of about 2 bar.
