Magnetic Cartridges & Grate Magnets

Magnets for Separation and Removal of Bulk Contaminants

Magnetic Cartridges (also called Rods or Tube Magnets) are engineered to achieve the optimum balance between reach-out and holding force. Cartridges can be mounted individually or in multiple-row arrays. Cartridge magnets are to be used in gravity free-fall magnetic separation applications.

Grate Magnets provide economical magnetic protection against tramp iron in mechanical or gravity conveying and processing systems. They can remove ferrous fines, fragments, and larger metal objects from dry particulates, liquids, and slurries.

Magnetic Cartridges

Both standard and heavy-duty models are constructed of durable 304 stainless steel tubing and are available with threaded hole, threaded rod, or plain sealed end plugs. 316 stainless steel is also available. End plugs are fully welded into the tough 1-inch diameter tubing for added durability.


General-Purpose Magnetic Cartridges


    • Ceramic, and High-Intensity Rare Earth magnets are available.
    • Select tapped, sealed or studded ends.
    • Standard 1″ round cartridges start at 4″ lengths.




Heavy-Duty Magnetic Cartridges

Cartridges_sqaureDesigned for maximum metal removal and for use where high flow rates or bridging might be a problem or where structurally stronger cartridges are required.

  • Durable, heavier-gauge stainless steel tubing resists wear and lasts longer in demanding applications.
  • High-Intensity Rare Earth magnets are standard.
  • Heavy-duty 1 1/2″ square cartridges offer nearly two times the magnetic surface area of standard cartridges.

Grate Magnets

Grates can be installed or simply laid inside hoppers, pits, chutes, housings and bins, where they can be accessed for cleaning. Neodymium Rare Earth magnets are standard but Ceramic is also available, as well as the new NUHI™ Neo Ultra High Intensity magnets. All finishes available including food, sanitary and USDA. Learn how the NUHI™ Cartridge Magnet can protect your customer, product and brand HERE.
