General
This user manual contains information for the correct operation and maintenance of your device. It also
contains instructions for avoiding possible injury and serious damage and it allows a safe and as
trouble-free functioning of the product as possible. Read this manual thoroughly before putting the
device into operation, familiarise yourself with the operation and control of the device and follow all
instructions precisely.
•The data published in this instruction manual is based on the available information at the time of
delivery. This is issued subject to later amendment.
•We retain the right to amend or modify the construction and/or model of our products at any time
whatsoever without any obligation to modify any previously supplied products accordingly.
Ferromagnetism
The working principle of the device rests on (Ferro)magnetism.
Ferromagnetism is the basic mechanism by which certain materials such as iron cobalt and nickel can
get magnetized when exposed to an externally applied magnetic field. Materials that remain magnetized
after the external magnetic field is removed, are called permanent magnets. Most magnetic materials
lose their magnetism after the external magnetic field is removed. Most alloys of iron, cobalt and nickel
are magnetic. However, some stainless steel alloys like AISI304 or AISI316 are only slightly magnetic.
Because in most cases it will be Fe parts that will be Ferro-magnetically influenced, we will use the term
‘Fe’ in this user manual when we mean ferromagnetic material

Danger of magnetic field
The magnets generate a powerful magnetic field that strongly attracts ferromagnetic (Fe) materials.
Always take into account that these materials may suddenly be drawn towards the magnet, very
powerfully. This applies to steel workbenches and steel tools, but also to Ferromagnetic materials
carried on your person, such as coins in your wallet or your keys. Make use of non-magnetic tools and
workbenches fitted with a wooden worktop and preferably a non-Fe frame (for instance stainless steel).
Always be aware that Ferromagnetic parts will be attracted -- even personal items - if you are
closer than 0.3 meter to a magnet.
Danger - strong magnetic field!
People fitted with pacemakers should on no account enter the magnetic field
(within a radius of 1 meter).
Prohibited for people with pacemakers!
Credit cards, chip cards, computer disks/tapes, computer screens, watches,
etc. may be damaged or destroyed if they enter the magnetic field (within a radius of 0.5 meter).
Danger for magnetic cards!

Device description
Intended use / user indications
Product
The device is suited for separation of ferromagnetic (Fe) parts out of free flowing powder and granular
products, grain size up to 10 mm, such as flour, sugar, coffee beans, plastics, ceramics, etc.
Not suited for (moist) products that are sticky and/or badly flowing.
Fe particle size
Suited for product flows with Fe particles of 30 µm and larger, depending on magnet strength quality.
See product specs in the appendices for exact Fe parts size specification.
Product should be free of Fe part size and weight that can cause damage to the magnet bar tubes.
Mechanical or other sieving of larger parts is advised.
Foreign part size
Foreign part (like other metals) size that can cause damage to the magnet bar tubes have to be filtered
out.
Mechanical or other sieving is advised.
Temperature
Suited for surrounding temperatures from -20 °C up to +40 °C and product temperatures from -20 °C up
to +60 °C with standard Neoflux® magnets.
See product specifications in the appendices for max. product temperature.
The magnet is to be protected against higher temperatures than prescribed, because the magnet might
lose magnetic force permanently when exposed to high temperatures
Air pressure
The relative pressure inside the device must be under 0.2 barG. The relative vacuum inside the device
must be under -0.5 barG.
If an air pressure coupling is mounted on the flange, it may be redundant if the product channel has an
overpressure. Also, it may not function if there is a relative vacuum in the product channel.
Air pressure between seals on motor shaft and housing
An air pressure seal may be mounted between the motor and Cleanflow housing. This is to prevent any
oil or debris from the motor reductor from entering the product channel. If an air coupling is mounted to
the motor mounting flange, then the maximum supply pressure is 0.1 barG. This pressure may only be
connected if an air coupling is mounted. If a closing plug is fitted, then the system is not suitable for
applying an overpressure. The air coupling will only work optimally if the air pressure is equal between
the outside and inside of the product chute.
Free space
Make sure that there is approximately 1 meter of free space around the SECR to perform and ease the
inspection and maintenance operation.

Device description
13
Noise level
The noise level generated by the device is significantly below 70 dB(A).
Vibrations
The magnet is to be protected against strong external vibrations, because the magnet might lose
magnetic force permanently and or the brittle ceramic magnet material might break.
The only vibrations caused by the SECR are caused by the moving and rotating magnet bars. The
product channel in which the device is mounted has to be stiff enough to damp out the (relatively small)
forces of the moving and rotating magnet bars.
Cleaning
Minimum 2x per day cleaning (Fe parts disposal) of the device is advised for an optimal magnetic
separation and to prevent Fe accumulation on the magnet bar tubes and the problems that can be
caused by that. Clean more often when the magnets catch a lot of Fe parts and less often if proven that
2x per day is too much. Clean magnets have the best separation result, so make sure to clean more
often than assumed necessary, to achieve a satisfactory result of the magnetic device.
Deliverable specials
High product temperatures
For high product temperatures there is the possibility of using other magnet material than the standard
Neoflux® magnets. See product specs in the appendices.
Abrasive products
If you have an abrasive product, we can supply the magnet bars and /or inside housing with a protective
coating, like for instance a tungsten carbide coating.
Use in FOOD product flows
The cleanflow magnet can be adapted so that it can be used in almost any food stream. It’s standard
execution already has few gaps in the product channel. The product channel (or even complete housing
+ magnet bars) can be delivered in gap-free SS AISI304 or AISI316, or in combination with other – for
instance prescribed or delivered by customer – food appproved materials. Surface treatments like
electrolytic polishing, staining, etc, are also possible.

Device description
14
Working principle
•The rotating clean flow magnet is suited for separation of ferromagnetic (Fe) particles out of product
flows.
•By rotation of the magnet bars on a rotor, bridge forming on the bars is relatively little and thus a
much better Fe separation result is created.
•For becoming a high quality de-ironing processes, clean flow magnets have a very high magnetic
field value on the magnet bars. The “sticking” strength of the magnets and the speed of the rotor can
be differently designed, varied with the flow rate, type of product and magnet selection.
Figures: Basics of Fe separation process Cleaning by pulling out rotor and extractor
•The product, contaminated with Fe parts, passes one or more magnet bars while flowing through
the rotating clean flow magnet.
•The Fe parts will be ‘sucked’ towards a magnet bar and will cling onto it.
•The Fe parts will stay on the bar until the magnet bars will be cleaned of the Fe parts
Before a cleaning action the product flow needs to be temporarily interrupted.
•Cleaning the magnet bars of the Fe parts is very easy; the magnets can be simply pulled out of the
surrounding stainless steel tubes. When this is done the Fe parts will instantly fall off the tubes and
can then be caught and/or transported.

Standard Construction
1. The actual magnet unit is the rotor, consisting of an extractor and several very strong Neoflux®
magnet bars.
2. The extractor consists of 2 flanges with tubes welded or soldered in-between.
3. The magnet bars are mounted on one side to a flange and form the magnetic part of the rotor
assembly, it fits exactly into the extractor part of the rotor.
4. The flanged motor is bolted to the SS housing.
5. The housing has an inlet and an outlet flange with holes for bolted mounting.
6. The rotor can be taken out of the housing for cleaning or inspection, by opening the door, which is
held tightly closed by 2 fastener clamps.
7. Some SECR types have an extended motor shaft and an extra bush between housing and motor to
help to discover oil loss through the shaft more easily and so further reduce the danger of motor oil
penetrating into the product canal.
8. The control box is connected to the safety latch switch unit; if the door is opened during production,
the motor will shut off. The safety latch is locked into the latch safety switch unit.
9. The silicone seal at the door prevents leakage of product out and dirt into the device.

Magnetic bar housings remarks
•The cleanflow has fragile magnetic bar housings. The housings have a very small wall thickness,
which ensures maximum déferrisation.
Heavy contamination of the product flow can damage the housings.
•Make sure that heavy or non-magnetic parts are filtered out of the product flow before it passes the
cleanflow magnet! Place a sieve in the product stream before it reaches the cleanflow!
•During maintenance or cleaning be very careful with the magnetic bar housings.
Always place the magnet section with the ends down and the flange up, not on its side.
•When the magnetic bars are damaged it may be difficult to move the bars in their housings; If this
occurs it is advised to replace the tubes or let the tubes be replaced by Goudsmit, to avoid further
damage.
•Damage to the magnet bar tubes and damage caused by damaged magnet bar tubes is not covered
by the guarantee. Please take the utmost care when cleaning the device!

Installation
17
Installation
Placing and transport procedures
The rotating clean-is always to be lifted by 4 lifting lugs!
Keep the centre of gravity into consideration. This is not in the middle of the device, but closer to the
motor side.
•Use proper lifting devices that suit with device’s weight. Clear the area under the magnet during
transport.
Read the weight of the clean flow magnet on the identification plate.
•The device is delivered in a wooden box. Bolt a lifting lug to each of the 4 corners of the magnet
housing flange for stable transport process. Keep each corner on the same level for proper
alignment before installation.
•Close the door and quick locking mechanisms properly to prevent the extractor and magnets of
falling out of the housing. Check that the rotor (extractor and magnets) is clamped tidily to the shaft.
•Bolt the flanges of the device tidily to the inlet and outlet flange of your product canal. Improper
alignment and loose assembly may cause leakage of raw product. Ensure that the channels are
strong enough to support the weight of the clean flow magnet and raw product in it.
•It is best to install the clean flow magnet in a well reachable height to the operators. A good height
eases the cleaning process.
•Avoid any impact during transport to prevent damage, especially to the rotor. Damage to the
extractor can cause magnets to “stick” into the extractor.
•To prevent physical damage and abrasion the cabling on the outside of the device requires
adequate protection.
Gasket material / grounding
To prevent the build-up of static electricity, make sure there is metal bridge between the magnetic
device / product channel and the installation. The completed installation must also be grounded.
