MRF 3 Technical Description
Technical Description
The MultiRheo Filter (MRF) is a stationary filtration unit used for the full-flow and
bypass filtration of low-viscosity fluids for the separation of particles of 100 µm to
1 µm (absolute).
The MultiRheo Filter is a filter series for the use of Flexmicron filter elements.
Suitable Fluids
NOTICE
Impermissible operating media
The MRF will be destroyed
►Only use the MRF in connection with:
- lubrication and mineral oils or media based on mineral oil
- cooling lubricants
Filter Design
The total pressure of the filters at a specific flow rate is comprised of the housing
and the element . The pressure loss of the housing can be determined using
the following pressure loss curve.

MRF 3 Technical Description
Pressure loss curve, housing
bar
Flow rate in l/min
The upper housing curve holds for mineral oil with a density of 0.86 kg/dm³ and a
kinematics viscosity of 30 mm²/s. The lower housing curve holds for water at 20°C.
For turbulent flow, the differential pressure will change proportionally to the density;
for laminar flow, it will change proportionally to the density and viscosity. The flow
velocity should not exceed 3 m/s at the filter inlet for oil and 4 m/s for water.

MRF 3 Commissioning
HYDAC FILTER SYSTEMS GMBH en Page 20 / 32
BeWa MRF3 3218003c en-us 2012-02-22.doc 2012-02-22
Commissioning
The MRF is supplied ex works without any filter elements. Prior to commissioning,
insert the filter elements into the filter housing, as described on page 22.
Set up
Set up the unit horizontally on a level surface.
Make sure that there is sufficient space above the filter housing to remove the filter
elements.
Notes on Piping / Hosing
Make sure that no vibrations or stress/loading from other machinery and equipment
are carried over to the filter housing. If necessary, use expansion joints.
The pressure differential in a hydraulic line depends upon:
flow rate
kinematic viscosity
pipe dimensions
density of fluid
The pressure loss can be estimated for hydraulic oils as follows:
Δp ~ 6.8 * L / d4* Q * V * D
Δp = Pressure differential in [bar]
L= Line length [m]
d= Internal line diameter [mm]
Q= Flow rate [l/min]
V = Kinematic viscosity [mm²/s]
D = Density [kg/dm³] Mineral oil based hydraulic fluid has a density of
~ 0.9 kg/dm³.
This applies to straight pipelines and hydraulic oils. Additional threaded connections
and pipe bends increase the pressure differential.
Keep the height difference between the pump and the oil level in the tank as low as
possible.
Hoses must be suitable for suction pressures of at least -0.5 bar.
Constrictions in the connections and lines should be avoided. This could
compromise suction output and cause cavitation .
Take note that the nominal size of the connected hoses/piping must be at least as
large as the inlet port sizes.
