“One size does not fit all and
using the right jetter nozzle for
the job is critical to success.”
DIFFERENT NOZZLES FOR DIFFERENT APPLICATIONS
•
Chisel point nozzle
The punching nozzle is a tool for solving
heavy blockages of all kinds. These are
mineral deposits, ice, mud, sand and
grease. It is also very suitable for dissolving
roots. In addition, the sharp edges penetrate
with their kinetic energy like a chisel which
rips and cuts roots free.
•
Grenade Bomb
The grenade bomb nozzle cleans the
circumference of a pipe (grease, seal skin)
while remaining in the centre of the pipe.
When the nozzle is withdrawn, heavy soiling
(gravel, sand and deposits) is also released
and the pipe is completely cleaned.
•
Flounder
The flounder floats extremely quickly, so
large deposits of sand, gravel, stones or
grease on the channel bottom of the pipe
are cleared away. A deep cleansing in highly
water-bearing ducts is also possible (no
float). You also need less water due to the
large washing capacity.
•
Ejector nozzle
Casings and runners made of VA – a
specific high-grade of stainless steel.
Recommended working pressure 100 to
130 bar. Maximum permissible pressure
200 bar. Ejectors gently remove sand, mud,
gravel, etc. from the tube floor. The ejector
must be immersed in water and can be used in locations which are
difficult to reach (e.g., culverts) or in sensitive systems.
•
Spider chain slingers
You can remove roots, mineral deposits and
other blockages in pipes with diameters of
80‒900mm. Renovations often begin with
a round cleaning of the pipe: the easiest
way to do this is with a spider chain slinger.
The change slinger uses fresh water or
exceptionally well filtered water. This can also be used for removing
encrustations, root growth and roughening of the pipe walls,
especially before pipe repair workings. PA
