Flow magnetic separators
The flow-through magnetic separator can be used as a preliminary stage for protecting technology, preventing metal particles from entering equipment that could damage it. It can also be used to purify mixtures to the highest possible degree of purity, with the separator placed at the end of the line. Thanks to the superbly designed magnetic labyrinth, a high level of impurity capture is achieved. It is installed on circular pipes, where it replaces part of them, and the purified mixture passes directly through the separator labyrinth.

Flow Magnetic Separators – In-Line Metal Separation for Powder and Granular Materials
1Understand that the separator becomes part of the pipe
A flow separator is installed on circular pipes, where it replaces a section of the run. The material does not pass beside the magnets, it travels through the magnetic labyrinth inside the body, which is what produces the high capture rate.
That also means the unit has to be planned into the pipe route, not hung next to it. Measure the available length in the run as well as the diameter before you order anything.
2Decide where in the line it belongs
There are two sensible positions. As a preliminary protection stage it stops metal particles before they reach equipment that they would damage. Placed at the end of the line, it purifies the mixture to the highest achievable degree before packing or dispatch.
Plants with a quality guarantee towards their customers often run both: one unit protecting the machinery, a second one guarding the final product.
3Take the size from the pipe diameter
Separators for connection to circular pipes are manufactured as standard in sizes 50, 65, 66 and 100 mm. The current range also includes ready-made DN 32, DN 50 and DN 100 units, so smaller runs are covered as well.
The diameter has to match the pipe exactly. Reducing the cross section in a pneumatic or gravity line changes the flow behaviour and can create a blockage where none existed before.
4Choose the version and the magnetic strength
Flow separators come in three versions, ECO, Standard and UP, with magnetic strengths from 7,400 Gs up to 12,200 Gs. The stocked DN units state 10,900 Gs.
ECO suits occasional, visible contamination in a clean process. The stronger versions earn their price where fine iron dust, rust and abraded particles appear continuously, or where the product goes to a customer with contamination limits.
5Single-shell or double-shell
Both designs are available and the difference shows up in operation rather than in the datasheet. Compare them on how the unit is opened, how the captured metal is removed and how much of the process has to stop while that happens.
If the separator sits in a sealed or hygienically sensitive line, ask us which shell design fits your cleaning regime before you decide on the size.
6Confirm it is the right design for your transport
These separators are made for closed systems, pneumatic transport lines, vacuum conveying, gravity feed tubes and processing lines where the product must stay sealed and free of contamination, handling powders, granules and bulk solids.
Material on an open belt belongs under a magnetic plate, and material falling through a square opening belongs on a grid or a telescopic grate separator.
Tip: Send us the pipe diameter, the material and fraction, the throughput and whether the line is gravity fed or pneumatic, plus the length free in the run. Pneumatic lines in particular need the flow behaviour checked before the pipe is cut, and that is a five minute conversation compared with a rebuilt section.

Frequently asked questions about flow magnetic separators
Separators for connection to circular pipes are manufactured as standard in sizes 50, 65, 66 and 100 mm, and the range also includes ready-made DN 32, DN 50 and DN 100 units. The separator replaces a section of the pipe, so the diameter has to match exactly and you also need to check the free length available in the run.
It is the internal arrangement that forces the purified mixture to pass directly through the magnetic field rather than sliding past it. The design is what achieves the high level of impurity capture in a closed pipe, where there is no room for an operator to redirect the flow. In practice it is the reason a flow separator outperforms a magnet simply fitted to a pipe wall.
They differ in construction level and magnetic strength, which across the range runs from 7,400 Gs up to 12,200 Gs, in single-shell or double-shell designs. ECO suits occasional visible contamination in a clean process. The stronger versions pay off where fine iron dust and rust appear continuously, or where the finished product has contamination limits.
Either as a preliminary stage protecting technology, so that metal particles never reach equipment they would damage, or at the end of the line where it purifies the mixture to the highest achievable degree. Operations that guarantee product purity to their customers often install both, one protecting the machinery and one guarding the final product.
Yes. Flow separators are designed for closed systems, pneumatic transport lines, vacuum conveying, gravity feed tubes and processing lines where the product must remain sealed and contamination free. They handle powders, granules and bulk solids. State the transport type when enquiring, because it affects which design suits the flow conditions.
A flow separator belongs in a closed circular pipe. Material falling through a square opening in a gravity line is handled more cheaply by a magnetic grid or a telescopic grate separator, and material travelling on an open belt belongs under a magnetic plate. Liquid media are handled by a separation vessel rather than by any of these.
In a closed pipe nobody can see the contamination and nobody can pick it out by hand, which is why the separator itself has to do the whole job. Our flow separators are installed directly on circular pipes, replacing a section of the run, and the material passes through a magnetic labyrinth that achieves a high capture rate instead of letting the stream slide past the magnets. The range covers versions ECO, Standard and UP with strengths from 7,400 Gs up to 12,200 Gs, in single-shell and double-shell designs, as standard for pipe sizes 50, 65, 66 and 100 mm plus ready-made DN 32, DN 50 and DN 100 units. Tell us the pipe diameter, the material and whether the line is gravity fed or pneumatic, and we will specify it.
