Made
in virgin polypropylene type NOVOLEM 1.106, the hemispherical design
of the head assures an excellent hydraullic repartition, not only
in the filtering process but also in the cleaning process, having,
also an excellent resístance to crushing.
The
union head-body is made by a mechanic-termic coupling that gives
a resistance and reliability very hard to obtain with other mechanic
systems of coupling head-body of the nozzle.

The
nozzles with a pitch of 0.2 mm have a free surface of 1.8 cm2
The nozzles
with a pitch of 0.5 mm have a free surface of 5.22 cm2
Each nozzle
is delivered completely equipped with their nut or ferrule, and ring made
in polypropylene, rubber and PVC respectively, ready for their installation.
APPLICATIONS
Open filters with concrete false bottom. With embedding ferrule..
Pressure
filtres with plastic or metallic false bottom.
Ion exchangers.
Active
carbon filters.
Made
in stainless steel AISI 304L or in AISI 316L, the construction material
gives to the nozzles an excellent mecanic and chemical resistance.
PROFILES
|
To
avoid the passing of particles that goes with the fluid, a lot of
meshes can be used with one condition that is the pitch must be
smaller than the size of the particle. However a lot of grooves
of the mesh can be obstructed with smaller particles compared with
the pitch due to particle's geometry or the filtering media breakdown.
This problem can be solved using our exclusive antiobstruction profiles
that assures that the particles don't get blocked in the mesh.

NORMALIZED
MODELS
MODEL BI
In this model, the tighten and fixing are made in the lower part. This
nozzle can be provided with a prolonging tube, when a liquid and a gas
(water and air) are used in the countercurrent cleaning. The normalized
length of the tube is 150 mm. Any other lengths can be provided under
request.
MODEL BC
This nozzle is specially designed for its installation in ramificated
collectors.
Identically of the previous model, the fluid is capted in the central
nozzle through a hole which measures depend on the desired pressure drop
in working conditions.
Also
we can produce, under request any kind of nozzle.
