xtreme™ TRAPS
The Xtreme™ Style rE separators available from Eriez remove weakly magnetic or very fine iron contaminants. These separators are made with Erium® 3000, a high quality rare earth permanent magnetic power source.
Erium® 3000 develops a magnetic field which has up to 25–times the strength of conventional ceramic or Alnico magnet materials.
The gap between low and high intensity magnetic separators has been filled with these
Xtreme magnets. They have more strength at a greater distance than conventional permanent magnets, high gradients and increased holding force. This means they can reach out and attract magnetic or very fine iron contaminants, and hold them so tightly that wipe–off by product flow is virtually eliminated.
All models of Eriez grate magnets are available with Xtreme elements. Existing units can be easily retrofitted with these more powerful magnetic assemblies.
NOTES:
Capacities vary depending on tramp iron size, liquid velocities and viscosities.

NEW OR RETROFIT if you have existing Eriez magnetic Traps, it is a simple matter to retrofit your existing separator body with Xtreme Style rE magnet assemblies. This provides a fast and economical way to upgrade iron separation performance. in many cases conventional ceramic magnets can be used to scalp easier–to–remove iron, with an
Xtreme rE magnet providing a final stage of separation to capture weakly magnetic contaminants.
FIVE OFTEN ASKED QUESTIONS ABOUT
RARE EARTH MAGNETS
Q. What’s so special about rare earth magnetic separators?
A. rE magnets offer solutions that were not available before to many fine and/or weakly magnetic iron contamination problems.
Their magnetic strengths fall in the medium–intensity range —
4,000 to 10,000 gauss. Previously, this strength was available only through high–intensity electromagnets, which are bulky, expensive to purchase and expensive to operate. All too often, the high–cost electromagnetic level of separation isn’t really needed, or its cost exceeds the “value added” to the product or process, making it difficult to justify.
The gap between high–intensity electromagnets, then, and the low–intensity conventional ferrite and alnico magnets, left a void in the medium–intensity range. rare earth magnets fill this void and allow economically feasible solutions to those ferrous contamination problems that are too tough for low–intensity separation but for which high–intensity separation was overkill.
Q. How can these new magnets benefit a processing operation?
A. The improved performance of rE magnets makes them particularly suited for certain applications. These include (1) the removal of fine iron, such as iron of abrasion, which is difficult to attract and hold because of its small mass; (2) the removal of weakly magnetic contaminants, such as iron oxide or rust, which do not respond well to conventional ferrite magnets; and (3) the removal of some stainless steel particles which have been rendered paramagnetic through work hardening.
Q. What exactly are rare earth magnets?
A. rare earth magnetic materials are neither rare nor earth. lanthanides is the proper name for these metals, which range from atomic number 57 to 71 on the periodic table of elements.
While rare earth materials have been known for a long time, it’s only recently that their use has become economically feasible.
Using new technology, rare earth metals are being combined with other elements to produce a new breed of permanent magnet.
Q. How are rare earth magnets different from other magnets?
A. The rare earth magnets are a major advancement, since they have much higher magnetic strength than conventional ferrite or ceramic magnets – (up to 25–times more pull) – yet provide similar circuit stability and long service life.
Properly designed rE magnets also have high magnetic gradients and greatly increased holding force. This means they can reach out and attract weakly magnetic or very fine iron contaminants and hold them so tightly that wash–off by product flow is virtually eliminated.
Q. Are all rare earth magnets this strong?
A. Definitely not. An Eriez magnetics Technical Center evaluation of different compounds and magnetic circuits showed that some rare earth compositions and circuits were only slightly better than ferrite (ceramic) magnet circuits, while others were many times stronger. This research led Eriez to the development of Erium 3000, a very powerful, third generation, permanent rare earth magnetic compound. Depending upon their circuit design, these rare earth magnets, as noted above, can provide up to 25–times the pulling power of conventional permanent magnets – with no increase in size.

The magnetic element, consisting of a group of magnetic tubes, is arranged to cause the material flow entering the body to impinge against the tubes and filter through the magnetic field, completely covering the open area.
This arrangement takes advantage of the material change in direction and the difference in inertia between the unwanted iron and the material carrying it. The magnetic circuit is designed so the entrapped iron will have a tendency to work around and cling to the down– stream side of the tubes…this action prevents iron particles from being washed off by the continuous flow of material.
The “pocket type” body contour of a ferrous trap tends to spread the material up and down and cause it to pass around and through the magnetic barrier in relatively thin streams without restricting the flow in the unit. With this design, installed with the closure either up or down, a sump is provided that tends to trap heavy nonmagnetic objects such as stones, etc. The rugged body will withstand working pressures to 150 psi (10.5 kg/sq cm).
For even better retention of micronsized particles and easier cleaning, the standard (ceramic and alnico) magnetic tubes can be covered with slide–on steel screens. Each of the thousands of points on the screen develops a high–gradient magnetic field which attracts and holds fine particles. The screens are cleaned by sliding them off the tubes and rinsing.
NEW EASY–TO–CLEAN

Eriez’ Super B-Traps (shown at left) are also available with rare
Earth easy–to–clean elements that insure complete removal of fine iron particles and speed up the cleaning process. Element stud can be padlocked to eliminate accidental cleaning.

PiPELiNES
This Ferrous Trap model has been designed to serve as an effective, low–cost, magnetic pipeline trap where operating conditions are not too severe. This unit is of nonsanitary cast bronze construction capable of withstanding pressures up to 150 psi (10.5 kg/sq cm). it is built for 2–inch (51 mm) pipelines; standard reducers can be used to adapt it to lines as small as
1/2–inch (13 mm). The powerful magnetic circuit is encased in one stainless steel tube. As a built–in safety factor, any material that might be brushed off by the flow will tend to pass the outlet and accumulate in the pocket at the end of the body.
mODEL L-2-F
FOr SEParatiNG/FiLtEriNG
This unit, basically the same as the model l, has a bronze filter sleeve that fits around the magnetic tube making the unit perform a dual separating operation. magnetic power from the tube draws and holds fine iron contamination, while the filter element catches and holds nonmagnetic fines, lint, etc. This model is recommended where more than magnetic impurities contaminate a product. The perforated brass filter with steel end discs is available with either .023–inch (.6 mm) diameter openings or .033–inch
(.8 mm) diameter openings. Each trap is furnished with one screen.

mODEL U
The model U Trap utilizes a rare Earth magnet circuit to remove fine and weakly magnetic contamination like rust, scale, or screen wire. model U Traps remove ferrous contamination from difficult–to–flow or chunky products likevegetables, salsa, or meat batters.
The special body design of the model U incorporates a gradually tapered transition that gently directs the product over a smooth magnetic surface. The body design does not incorporate diverters or baffles.
This design works well for applications where finger–style traps would plug due to large product size or where delicate products would break if forced against a baffle.
The model U Trap with its compact design can be installed easily into 3 or 4–inch (76 or
102 mm) lines. The standard unit is sanitary, incorporates our Super–Strength rare Earth magnet element, 316 stainless steel and
ACmE threads. Optional features include stronger and high–temperature rare Earth magnet circuits, ferrule and flanged ports.
