Liquid Traps in Food Processing Facilities

Manufactured to the highest standards, from Stainless Steel and available in Food and Sanitary Grade finishes, the liquid traps are manufactured using the latest grades of Rare Earth Neodymium Magnets to offer exceptional ferrous metal removal from liquid processing and conveying lines.

Our industry leading design allows the magnets to work at high temperatures without affecting magnetic and therefore metal removal performance. With a range of standard designs and the option of a heated water jacket, ideally suited to the chocolate industry, we have the ideal solution. The magnetic performance of our Magnetic Liquid Traps is so high they can also remove work hardened stainless steel fragments.

Cartridge Style

Cartridge Style Magnetic Liquid Traps


Our cartridge design magnetic liquid filters or Magnetic Traps are designed to ensure maximum contact is made between product and the magnetic fields by forcing liquids through a tightly spaced grid of magnets. These Cartridge Style Magnetic Liquid Filters are engineered for use with non-fibrous fluids. Ferrous contamination is magnetically extracted from the liquid flow by the extremely powerful Rare Earth magnet design  and held firmly on the cartridge surfaces. Simply and quickly cleaned by removing the magnetic lid assembly from the filter housing and wiping off the collected metal particles.

Features available include:

  • Easy spot check the magnetic cartridge for contamination with unique ‘Clean In Place’ (CIP) design
  • Standard 2”, 3” & 4” Line Diameter, 1/2" and other sizes available upon request
  • Magnetic Liquid Filters are held ex-stock for immediate dispatch
  • Designed for the Food and Powder and Bulk Industries
  • Optional Heated Water Jacket available

Plate Style

Plate Style Liquid Filters

Plae style liquid filters
Bunting Magnetics Plate style Magnetic Liquid Filters are available as either a Single Plate Magnet or Dual Plate Design. Using Bunting Magnetics unique magnetic plate design they are especially effective at removing ferrous particles from viscous and fibrous liquids and liquids containing larger suspended solids. These magnetic filters are designed to direct contaminants into the deep magnetic field from the magnetic plate where any ferrous or even work hardened stainless steel is captured, held and protected from the wiping action of the liquid flow. The incorporated deflector creates a gradual change in the direction of flow causing agitation of the product and exposes contaminants that would otherwise be blocked by suspended solids.

  • 400 Stainless steel tapered live step is standard. 316 Stainless steel is available
  • Finishes available are: food, sanitary and 3-A
  • Standard high temperature and high intensity rare earth magnets

Additional Info

Liquid Traps

This particular cartridge-style magnetic liquid trap contains the strong permanent magnetic cartridges from Bunting. In environments or production lines that feature non-fibrous fluids, where no solids bigger than 13mm are present, this design is perfect. Liquid chocolate is one such example.

This liquid trap is versatile in the sense that its installation can be effective in any position or orientation in a pipeline. The magnetic trap itself is T-shaped and it pushes the liquid in question through a tight grid of magnetic cartridges. As the strong magnetic field is created in the gaps that are between the cartridges, the magnetic particles are attracted to them (the gaps) and remain there until the cleaning process removes them. Not only can installation be achieved in any position in the pipeline but the process is also very straightforward, fitting into existing pipelines easily. There are a number of different fittings available which will help to deliver ongoing and reliable protection against metal contamination. Depending on your application, the traps can be supplied in a range of sizes and designs to suit both high temperature and sanitary environments.

The cleaning process is also straightforward: The magnetic cartridges are held in place by a lid – lift this up and away from the trap housing and then wipe away all of the ferrous metal which has been collected.

Cartridge-Style Magnetic Liquid Traps are the ideal solution for those looking to deliver product purity which involves protection from metal contamination. If you have any questions about which magnetic liquid trap is the best suited to your application and environment, please contact the team at Bunting Magnetics, who will be happy to give you guidance and advice.
