dedicated solutions.

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.

TECHNICAL CHARACTERISTICS

HF 650 series can be used on hydraulic circuits with working pressure up to 35 bar and are particularly specified for
hydrostatic charge pumps, cooling circuits along with the traditional fluid filtration on the tank return line.
The standard filters are supplied with by-pass valve set at 25 psi (1,7 bar) or at 51 psi (3,5 bar).

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
filtering element.

Total Dp = Dp in housing + Dp in element

In filters of HF 650 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 ISO VG46 with kinematic viscosity of 120 SSU (30 cSt) and density of 7.29 lb/gal (0,856 kg/dm3).

Calculation example

Filter HF650-20.180-AS-FG010-B17-GE-B-XA-F-Y
Flow rate= 22.5 US gpm (85 l/min)
Kinematic viscosity: 120 SSU (30 cSt)
Oil density : 7.29 lb/gal (0,856 kg/dm3)
Filtering degree: 10 mm

Data obtained from the diagrams:

Dp in housing = 3.62 psi (0,25 bar) (page 4)
Dp in element = 1.60 psi (0,11 bar) (page 5)
Total Dp = 3.62 + 1.60 = 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-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/dm3) the value of the Dp in the head-bowl will be:

Dp of diagram (psi) • Oil density ( lb/gal)

Dp in housing = [psi]
7.29 (lb/gal)
Or
Dp of diagram (bar) • Oil density ( kg/dm 3 )
Dp in housing = [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/dm3) and kinematic viscosity different to 120 SSU (30 cSt) the value of Dp in the
element will be:
02/01.2016

Oil density (lb/gal) Oil viscosity (SSU)

Dp in element = Dp of diagram (psi) • • [psi]
7.29 (lb/gal) 120 (SSU)
Or
Oil density (kg/dm 3 ) Oil viscosity (cSt)
Dp in element = Dp of diagram (bar) • • [bar]
3
0,856 (kg/dm ) 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.

SPECIAL VERSION FOR HYDROSTATIC TRANSMISSIONS

The in line HF650 filters can be applied to hydrostatic transmission circuits by using a special pressurization valve.
The oil flow coming from the open circuit is pressurized at 7.25 psi (0,5 bar) and sent to the hydrostatic circuit depen-
ding on the charge pump need, while the excess flow is normally discharged into the tank.
For a correct filter choice, please contact our technical department.
