General deScription
MIA-FD is the acronym for Manifold Instantaneous Auto-compensating Flow Divider. The VIVOIL MIA-FD ow divider is the
answer to the market request for continuous improvement of:
• Precision: All components has been re-engineered to allow for a tolerance constructive reduction and to reach a hi-
gher uniformity between elements. In addition we have included an internal auto-compensating system that removes
the dependency from the pressure dience between elements.
• Modular: each element is a single independent unit
• Congurable: each element can have added valves and other modular elements with CETOP NG6 , ISO 4401-03-02-0-
05.
• Expandable: the system can be improved by adding new divider elements on to an existing ow divider.
• Simple: the completed ow divider is a real compact manifold system and is easy to install.
The MIA-FD FLOW DIVIDER is not only a simple ow divider and combiner, but it is a system to distribute and feed with
constant and independent ow rates for the various circuit branches. The open architecture of the MIA-FD has been deve-
loped to be integrated into dierent functionality that will follow the customers requirements.

dependence of the error trend from temperature/ViScoSity
The below graph shows the typical trend of the error captured during experimental tests:
The green line represents the maximum real error measured during the tests.
With oil temperatures up to 45 °C the absolute error between elements is < 0.8 % (with a pressure dierence from 0 to
180 bar)
Note: All products were tested after assembly
and an initial run time to adapt the parts to each
other. The complete adjustment requires several
hours.
Test details:

Flexible pipes EN 853/2SN 3/8 GAS L=2000 mm
Cylinder bore ø100 mm - Cylinder rod ø50 mm - 1000 mm stroke.
floW diViSion preciSion definition:
We dene the ow division error as the dierence between the maximum and the minimum volume of ow on the outlet
of the ow divider (expressed in a percentage).
Example: One 4 element ow divider feeds 4 equal cylinders with a 1000 mm stroke.
When the rst cylinder C1 reaches the end of the stroke at 1000 mm, the other cylinders will have dierent strokes, becau-
se of the error ow division.
The dierence between the maximum stroke on C1 and mini-
mum stroke on C3 is:
1000 - 995 = 5 mm
Therefore the absolute ow division error is:
(5/1000)*100 = 0,5%
Attention! In order to express the error as a percentage, you
must calculate the maximum misalignment between all stroke
positions.
Please remember that the nal error rate is made of the ow di-
vider error, the oil compressibility, the pipes, seals and cylinders
elasticity, in addition to the volumetric eciency of the nal
uses (such as motors).

mia-fd floW diVider
An auto-compensating system has been added inside of the MIA-FD making the ow division does not depends on the
pressure applied on each of the elements. This system does not require any adjustments.
With this type of ow divider there is no pressure amplier eect, and therefore there is no risk of making the safety valve,
that is positioned before the ow divider ineective.
Due to the higher precision of this solution, no relief valve is necessary in the main part of the applications. Relief valves
can be installed at any time and only in the elements that need them. This is accomplished by using a CETOP connection
on top of each element.

hoW it WorkS General information
The ow divider is made up of two or more elements (sections). Inside each element there are a couple of gears that deter-
mine the quantity of oil that goes from the inlet to the outlet. The gear couples are connected mechanically so that all of
them haves a synchronized rotation.
For this reason, the ow rate that passes through each element has a constant ratio determined by the displacement of
each element.
Gears can rotate in both directions, making the ow divider reversible.

floW diViSion modality
Inlet from 1 (P/T) to An: The ow is sent to the
gear element (01) that divides it into independent
ow rates. The uid goes through the compen-
sation system and feeds the P from the CETOP
connection on each element.
The CETOP closing plate (03) connects P with A
which is communicating with An.
The Bn connection is communicating with the B
port on the CETOP interface on each element.
The CETOP closing plate (03) connects B with T and
consequently is communicating with the common
line (04) and connection 2(T/P)
The Bn connection can be used for the backline
from the actuators.
floW combiner modality
Inlet form An to 1(P/T): the dierent ow rate
gets in from the An connections that are all com-
municating with the A port in the CETOP interfa-
ce of each element.
The CETOP closing plate (03) connects A with P,
then feeds the gears (01)
With this working method it is recommended
that you insert an adjustable ow regulator (06)
and assemble it (as per the scheme 2) on the ow
divider outlet in order top increase the precision.
This will slow down the descending phase and
consequently give to the gears a counterpressu-
re.
Bn connections, can be used to send oil ot the
actuators, because they are directly communica-
ting through the common line (04) to the 2 connection (T/P) .
cetop connection interface uSe on the floW diVider StaGeS:
From the above schemes :
• When the oil works as in Scheme 1 the P connection on the CETOP interface is the outlet and T is the back line.
• When the oil works as in Scheme 2, the P connection on the CETOP interface is the back line and T is the outlet.
This is really important when you are considering the use of CETOP components on top of each element.

cetop interface on the floW diVider StaGeS:
Valves and modular command elements can be installed on each ow divider element.
CETOP 3 NG6 , ISO 4401-03-02-0-05.
To allow this, it is necessary to remove the CETOP closing plates.
When a CETOP element is installed, you
should always check that its characteri-
stics and use limits are appropriate to the
actual use.
You must respect all of the indications
and instructions provided by the manu-
facturer (ie: assembling, use, installation,
safety, torque couples).
The CETOP component can eect on the
nal precision, becuase it acts after the
ow compensating system, . (As an exam-
ple, the error can drastically improve be-
cause of internal leakage on an installed
CETOP component)
Vivoil Oleodinamica Vivolo declines all
possible responsibility for bad functiona-
lity of the ow divider that is generated
from equipment, valves, commands and
any other possible element that has been
installed on the ow divider or is outside
the ow divider.

Check that the ow divider has not been damaged during the transport.
Pay close attention so you do not damage parts during the movement and assembling phases.
• Secure the ow divider on clean, at surface.
• Secure the ow divider by using the mounting brackets supplied or the threaded holes on the products sides. Secu-
ring the ow divider incorrectly can compromise the proper functionality of the system.
• To prevent additional noise caused by acoustic resonance, you should consider the use of anti-vibration mounts.
• Only remove the plugs immediatly before you connect the pipes.
• Pay careful attention so you do not introduce dirt into the ports or the CETOP connections

floW rate definition
The table shows the operating range of the individual elements of the
ow divider.
Higher ow rates with the same gear displacement, improve the preci-
sion, but cause a higher pressure loss and higher noise levels. For this
reason we suggest, whenever it is possible, the use of a ow rate close to
the optimal value dened in the table.
It’s important to check the ow rate for each element, even for the combi-
ning phase.
Working pressures indicated must be considered maximum continuous
values.
Pressure peaks of approximately 10 percent are allowed.

• Execute all of the proper connections
• Check that all of the valves that can inuence the pressure are adjusted to the minimal values during the rst start up.
• Check that no valves, taps, plugs, ow restrictors or other elements, that can obstruct or restrict the oil ow or impro-
ve the pressure, are present after the ow divider.
• Check the proper connection tightening and the proper circuit positioning
• Always respect the recommendations and instructions from the machine builder, where the ow divider is
installed, concerning safety and how to install pipes, valves, electrical connentions, etc.
• Start the ow divider for a short period with no load on the uses
• Immediately stop the use if any strange noise, leakages, strange movements, etc. cause you to doubt or suspect there
are issue with the proper functionality.
• Purge the air from the circuit. In order for the ow divider to work properly, no air should be present in the circuit (no
foam in the tank).
• Perform many cycles without load on the uses.
• With all the actioning deactivated and no pressure on all the pipes, check that no leakage occurs and that all pipes,
ttings and connections have been properly tightened
• Adjust the valves and perform some empty cycles.
• After all the steps before have been succesfully passed, start by gradually adding the load on the uses on step at a
time.

• Do not exceed the temperature indicated in this catalogue
• Check that no air is in the circuit (no foam in the tank).
• If CETOP valves are applied on the ow divider, respect the user instructions from the manufacturer.
• Always respect the recommendations and instructions from the machine builder where the ow divider is
