Storing the MRF
Storage may not be done unless the MRF has been completely drained, cleaned and
flushed and the filter element removed.
Storage temperature: +5°C to +30°C
Humidity: up to 80% relative humidity
Air: Clean, salt-free air, not near oxidizing substances (rust
film).
Storage duration: Indefinitely.
After a storage > 2 years all seals are to be exchanged
before the introduction.

MRF 1 Checking the scope of delivery

BeWa MRF1 3221266e en 2009-06-08.doc 2009-06-08
Checking the scope of delivery
Upon receiving the MRF check it for any damage in transit. Do not put the MRF into
operation unless it is in perfect condition. Report any damage in transit to the
forwarding agent or the HYDAC department in charge immediately.
The MultiRheo filter is factory-tested for leakage and proper functioning and is properly
packed.
The fluid connections are all sealed with plastic plugs to prevent the intrusion of
contaminants into the filter during transport.

MRF 1 Calculating filters and filter elements
HYDAC Filter Systems GmbH en Page 14 / 36
BeWa MRF1 3221266e en 2009-06-08.doc 2009-06-08
Calculating filters and filter elements
The total pressure of the filters at a specific flow rate is comprised of the housing p
Δ
and the element pΔ. The pressure loss of the housing can be determined using the
following pressure loss curve. The pressure loss of the filter elements is computed on
the basis of the R factors.
Pressure loss curve, housing
Differential pressure (bar)
Flow rate (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.
