3.7 Multipressure spray lance system
For each line pressure of 120 and 160 bar a kit of nine different spray lances is available, which
have been especially developed for the Multipressure spray lance system. Each of the nine spray
lances represents a combination of pressure and water volume. Users may therefore always
select the job-right combination of pressure and water volume.
The spray lances for 120 and 160 bar respectively differ in that the spray lances for 120 bar
are fitted with a GREY nozzle protection, and the spray lances for 160 bar are fitted with a
BLACK nozzle protection.
The nine spray lances are marked with each their colour and on the spray lance chart on the
DELTABOOSTER pressure, water volume and number of pumps may be read for the nine types
of spray lance.
The different water volumes and pressures depend on which high-pressure nozzle and which
pre-nozzle the spray lance is fitted with.
For further details on reactive power and nozzle sizes please refer to the Product Description
in sect. 1.9.
Alternative nozzles or spray lances should only be fitted in consultation with your Nilfisk-ALTO
specialists.
