Hydraulic filters type X-FUI, X-FER, X-FHP
suction, return and pressure filters
X-FUI, X-FHP and X-FER filters are desi-
gned to be installed respectively on the
pump inlet line, on the pressure line and
on the return line; they are suitable for
hydraulic mineral oil or synthetic fluids.
The filtering element of X-FUI filters is
made by a metallic net with square mesh.
The filtering element of X-FER and X-FHP
filters is made by inorganic microfibre
with an acrylic support and it can be
easily replaced.
They are available in different dimen-
sions:
- type X-FUI; to be installed immersed
on the pump inlet line: G 1/2”
to G 2

- type X-FER; to be installed on the

- type X-FHP; to be installed on the

X-FER and X-FHP filters may be delive-
red with visual or electrical clogging
indicators.

1) For water glycol it is better to use filters with a filtration rating which is not lower than 25 µm.
2) For phosphate ester fluids, consult our technical office and specify the kind of fluid.
3) For metallic cartridges, the filtration rating is fixed in micron by the maximum diameter of the sphere which is inserted in the net-mesh.
4) The cartridge of new filters type X-FER and type X-FHP is made by microfibre and when it is clogged it cannot be cleaned and it must be replaced.
It may be useful to have a spare cartridge with every single installed filter.
5) The microfibre cartridges of the new X-FER filters have a filtering power which is about 2,5 times higher than the filtering power of the metallic car-
tridges type SP-CFE and they have a size which allows them to be easily changed with this type of cartridge.

hey have to be installed immersed in the fluid in order to protect the pump.
They can be installed in any position: we recommend to avoid localized obstructions and to limit the fluid speed to 1 ÷ 1,5 m/s.
T

D
p

T
hey are not equipped neither with a by-pass valve nor with a clogging indicator; therefore regular controls of the filter conditions are necessary.
The filter must be entirely replaced when it is clogged.
Fluid temperature: -25 °C ÷ +110 °C
3.3 X-FHP
They have to be installed on the pressure line in order to protect the circuit components.
The cartridge is made by inorganic microfibre with acrylic support. When it is clogged, it cannot be cleaned and it must be replaced.
The cartridge will be easily replaced after the filter housing has been unscrewed.
The collapsed pressure of filtering elements is 20 bar.
They are equipped with a by-pass valve with opening pressure of about 6 bar ±10%.
They are delivered with visual/electrical indicator (see sections
쪪
and
쪬
) which opens or closes an electric contact when filter has
reached a preset value of contamination (5 bar ± 10%).
Fluid temperature: -20 °C ÷ +70 °C

T
hey have to be installed on the return line to tank.
T
he cartridge is made of inorganic microfibre with acrylic support. When it is clogged, it cannot be cleaned and it must be replaced.
The cartridge will be easily replaced after the cover has been removed.
The collapsed pressure of filtering elements is 10 bar.
T
hey are equipped with a by-pass valve with opening pressure of 2,5 bar ±10%. The by-pass valve is integral with cover.
They are delivered with visual or electrical indicator.
The visual indicator shows the progressive building-up of contaminant in the cartridge, by means of a red sector.
The electrical indicator (see sections
쪪
a
nd
쪬
) opens or closes an electric contact when filter has reached a preset value of
c
ontamination (2 bar ±10%).
