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, which are
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 condi
-
tions for all the components.

SIZING – PRESSURE DROP
The total pressure drop of the filter is calculated by summing the pressure drop value in the housing to the one in the fil
-
tering element.
Total Dp =Dp in housing + Dp in element
In filters of HF 620 series in normal working conditions, the total Dp must not be more than 1.4 psi (0,1 bar) on suction
line and 5.8 (0,4 bar) on return line.
In filters of HF 625 series in normal working conditions, the total Dp must not be more than 5.8 psi (0,4 bar).
To establish the values of pressure drop involved, the following pages provide some diagrams with curves referred to
the use of mineral oils SAE 10 with kinematic viscosity of 120 SSU (30 cSt) and density of 7.29 lb/gal (0,856 kg/dm
3
).
Calculation example
Filter HF620-30.155-AS-FG010-B17-GG-B-XB-DA-G
Flow rate= 29 US gpm (110 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 = 1.45 psi (0,10 bar) (page 5)
Dp in element = 3.77 psi (0,26 bar) (page 8)
Total Dp = 1.45 + 3.77 = 5.22 psi (0,36 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-cal-
culated 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:
Dp in housing =
Dp of diagram (psi)
• Oil density ( lb/gal)
[psi]
7.29 (lb/gal)
Or
Dp in housing =
Dp of diagram (bar)
• Oil density ( kg/dm
3
)
[bar]
0,856 (kg/dm
3
)
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:
Dpinelement = Dp of diagram (psi)
•
Oil density (lb/gal)
•
Oil viscosity (SSU)
[psi]
7.29 (lb/gal) 120 (SSU)
Or
Dpinelement = Dp of diagram (bar)
•
Oil density (kg/dm
3
)
•
Oil viscosity (cSt)
[bar]
0,856 (kg/dm
3
)30(cSt)
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 indicated above.

ASSEMBLY AND REPLACING ELEMENT INSTRUCTIONS
01/03.2011
MOUNTING
Once you have checked the integrity of the filter inside its
package, proceed as follow:
A Take off the protection cap from the in/out ports.
B Secure the filter in the head through the holes of the upper
side (pos.2) tightening them as follows:
HF 620-20/30 and HF 625-20/30 = 44 lbf in (5 Nm)
HF 620-40 and HF 620-50 = 62 lbf in (7 Nm)
C Connect circuit's pipes to inlet and outlet ports using the
tightening torque indicated on pages 22 and 23.
D If the filter has a clogging indicator (pos.3 - 4 - 5 - 6 - 7 - 8), take
the protection cap off and screw the indicator in the dedicated
seat, then tighten to a tightening torque of 266 lbf in (30 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.
REPLACING ELEMENT
Once the working hour limit indicated in the manteinance
instructions of the system is reached or when the clogging
indicators point out the limit pressure drop created inside the
filter, the element must be replaced. Pay attention to the
drainage of hydraulic oil, therefore prepare suitable containers to
collect it.
Proceed as follows:
A Stop the system in "machine stopped" status.
B Secure any shut-off valves on the hydraulic circuit.
C Remove the clogged element by hands-crewing it from the
filter head (pos.2) or if needed by using a strap wrench.
It is advisable not to recover the oil in the element since it is
full of clogging particles.
D Lubrificate the new element's seal (pos.1).
E Screw the new element until reaching the ledge with the
filter head (pos.2).
F After reaching the ledge, hand-screw the element for 3/4
more (for series 20) or 1/2 more (for series 30, 40 and 50).
G Re-open the eventual valves closed before.
H Start the machine for a few minutes.
I Make sure there are no leaks.
