Hump Magnet

The double-bend (S/hump) pipe geometry presses the product onto the magnet surface at two points; it provides high capture efficiency in pneumatic conveying lines.

A two-bend transition

The hump magnet is a Z transition with two bends added to the pipeline. As the material moves through this transition, it deflects first in one direction and then in the other, coming into contact with two separate magnet surfaces. The aim is to guide the flow physically and guarantee that every particle passes through the magnetic field.

Why it is more effective than a straight pipe

A magnet placed on a straight pipe holds only the particles passing close to it; material flowing on the opposite side of the cross-section does not feel the field at all. The hump geometry forces the flow onto the magnet surface. That is why it is one of the solutions with the highest capture rate in pneumatic and free-fall lines.

Where it is used

Pneumatic conveying lines, discharges under silos and closed-pipe bulk material transfers. Placing it at points where the line already changes direction both saves space and creates no additional pressure loss.

When choosing

Line diameter, material throughput and wear load are decisive. With glass-fiber raw material the inner surface of the bend is exposed to wear; at this point a wear resistant body should be preferred — the same problem is seen in pipe elbows. Cover access for cleaning should be planned at installation.

Positioning tip

Placing it at points where the line already changes direction both saves space and creates no additional pressure loss. The distance between the two bends and the bend radius determine the wear behavior; with abrasive raw material, periodic inspection of the inner surface is recommended.
