In line high pressure filters
THE IMPORTANCE OF AN EFFICIENT FILTRATION
The main cause of anomalies in hydraulic systems has to
be attributed to the presence of contaminants in the fluid.
The nature of the contaminant may be: gaseous, namely
air mixed with the fluid; fluid, it depends on water
penetrating the fluid; solid, therefore particles of various
origins and dimensions.
Customers who operate equipments are always focused
on obtaining the best possible performance, lower
energy consumptions and greater respect for the
environment.
These characteristics can be attained by using top
quality components in the hydraulic system for
generating and regulating the fluid power, which are also
more sensitive to the presence of contaminants in the
fluid.
Starting from these requirements, we understand how
important and fundamental it is to prevent the presence
of air and water from mixing in the fluid tank by using
dedicated solutions.
It is also crucial to limit the presence of solid particles in
the hydraulic circuit through a suitable filtering system,
which is indispensable to maintain the project
requirements of the system over time and to keep
running costs low.
The correct choice of a filter and its optimum position in
the hydraulic system requires the same care and
experience needed to choose all the other components.
The use of filters with larger filtering surfaces reduces, at
equal flow rates, the superficial contaminant load and
therefore the filter's life is extended proportionally.
To maintain the maximum efficiency of the system, the
filters must have a clogging indicator showing the
differential pressure on the filtering cartridge and to
immediately point out when the cartridge needs
replacing in order to prevent the by-pass valve from
opening.
The following factors should be analysed when choosing the ideal filter:
Ø
The filtration degree required to protect the most sensitive component from contamination
Ø
The points of the circuit in which the filters have to be installed
Ø
The working pressure of the system
Ø
The maximum flow rate and the type of fluid to be filtered
Ø
The duty cycle
Ø
The retention efficiency of the filtering cartridge
Ø
The contaminant accumulation capacity of the filtering cartridge
Ø
The working ambient temperature
Each filter used generates a pressure drop that increases continuously as time goes by. This pressure drop represents
an efficiency index of the filter itself.
When the hydraulic system is about to be assembled, all the components must be perfectly clean and the fluid has to be
added through a device complete with a filter.
During the test phase, it is advisable to run some work cycles at low pressure in order to create the best possible
conditions for all the components.

TECHNICAL CHARACTERISTICS
The filters of the HF760 and HF761 series are connected
to the pressure line of the circuit and protect the system’s
components against contaminant particles.
The standard filters are supplied with by-pass valve
calibrated at 87 psi (6 bar).
HF761 serie differs from the HF760 one because adopts
HE K-86 elements.

SIZING – PRESSURE DROP
2) The pressure drop of the element is proportional with the oil density and kinematic viscosity, therefore for oil with
density different to 7.29 lb/gal (0,856 kg/dm
3
) and kinematic viscosity different to 120 SSU (30 cSt) the value of Dp in the
element will be:
Now you sum the values of the pressure drop of the housing to the value of the pressure drop of the filtering element,
always making sure the total Dp does not exceed the pressure limit of 11 psi (0,75 bar).
The total pressure drop of the filter is calculated by summing the pressure drop value in the housing to the one filtering
element.
Total Dp =Dp in housing + Dp in element
In filters of series HF760 and HF761 in normal working conditions, the total Dp must not be more than 11 psi (0,75 bar)
whereas, for use in harsh conditions, it must be within 14.5 ¸ 22 psi (1 ¸ 1,5 bar).
To establish the values of pressure drop involved, the following pages provide some diagrams with curves referred to
the use of mineral oils ISO VG46 with kinematic viscosity of 120 SSU (30 cSt) and density of 7.29 lb/gal (0,856 kg/dm
3
).
Calculation example
Filter HF760-20.106-AS-FG010-LC-B60-GD-B-DD-G
Flow rate= 12 US gpm (45 l/min)
Kinematic viscosity: 120 SSU (30 cSt)
Oil density : 7.29 lb/gal (0,856 kg/dm
3
)
Filtering degree: 10 mm
Data obtained from the diagrams:
Dp in housing = 2.00 psi (0,14 bar) (page 4)
Dp in element = 7,25 psi (0,50 bar) (page 5)
Total Dp = 2.00 + 7.25 = 9.25 psi (0,64 bar) (Dp is lower than maximum value admitted – therefore sizing is correct)..
If oil with different kinematic viscosity and different density is used, the values obtained from the diagrams will be
re-calculated considering the following indications:
1) The pressure drop of the housing is proportional with the oil density, therefore for oil with density different to 7.29
lb/gal (0,856 kg/dm
3
) the value of the Dp in the head-bowl will be:

ASSEMBLY
Once you have checked the integrity of the filter inside its
package, proceed as follows:
A Secure the filter to the attachment device via the threaded
holes in the head (pos.6).
B Take the protection caps off the oil inlet and outlet.
C Connect the circuit pipes to the filter, checking the flow
direction, which is pointed out by the arrow on the head
(pos.6).
D If the clogging indicator (pos.9 - 10 - 11) is immediately
mounted in the filter, take the protection cap off and screw
the indicator in the dedicated seat and tighten to a
tightening torque of 531 lbf in (60 Nm). If the indicator is
electric, complete the required connections.
E Start the circuit for a few minutes.
F Make sure there are no leaks.
Pos. Description
1 Filter bowl
2 Seal
3 Anti-extrusion ring
4 Sealing O-Ring
5 Filtering element
6 Filter head
7 By-pass valve
8 Sealing cap
9 Visual differential indicator
10 Visual electrical differential indicator
11 Visual electrical differential indicator

When ordering spare parts, always specify the
reference number, the filter code and quantity.
Example: Spare part pos. 4 - HHP02050 - Qty 2
ASSEMBLY AND REPLACING ELEMENT INSTRUCTIONS
REPLACING ELEMENT
Once the working hours limit indicated in the maintenance
instructions of the system is reached, or when the clogging
indicators point out the limit pressure drop created inside the
filter, the cartridge must be replaced, remembering that this
procedure involves the drainage of hydraulic oil and therefore
you need to prepare suitable containers to collect the oil.
Proceed as follows:
A Stop the system in “Machine stopped” status.
B Secure any shut-off valves on the hydraulic circuit.
C Unscrew the filter container (pos.1).
D Remove the clogged filtering cartridge (pos.5), making
sure no residual particles have settled on the bowl bottom
(pos.1).
E Make sure the O-ring (pos.4), seal (pos.2) and the
anti-extrusion ring (pos.3) are not damaged, otherwise
replace them and consequently position the new ones
correctly.
F Insert the new filtering cartridge, lubricating the sealing
O-ring beforehand.
G Screw the container tight (pos.1) making sure the threading
is screwed correctly. Tighten to a tightening torque as
indicated on pages 9,10,11.
H Start the machine for a few minutes.
I Make sure there are no leaks.
