Liquid Fingertrap Magnet — Tube Design

  • For use in product streams up to 100 PSI
  • Stainless steel construction
  • Quick-release clamps provide easy removal for inspection and cleaning of the magnetic element
  • All LFT-Series Trap Magnets are factory pressure tested at 100 PSI

 

Liquid Finger Trap Magnet
  1. Flowability and Strength Variations
    • Product is pumped through the magnet where ferrous tramp metal collects on either an array of 1” diameter magnetic tubes or a single 3” diameter magnetic tube. The tramp metal collects behind the tubes in the direction of product flow to prevent tramp metal wash off. Non-magnetic particles are separated by gravity and collect in the sump located in the bottom of the magnet enclosure.
  2. Diameter Ranges
    • Standard inlet / outlet sizes available from 1.5” diameter up to 12” diameter (HP model required for sizes over 4” diameter)
  3. Adaptable to Existing Lines
    • Easy installation into existing line using sanitary tri-clover, threaded or ANSI 150 pound inlet and outlet flanges
  4. Tube Configuration for Easy Cleaning
    • Exclusive tube configuration for easy removal of ferrous tramp metal from magnetic tubes
  5. Beauty Rings Protect Tubes from Impact
    • Welded tube support located on the bottom of the magnet element
      • Ensures proper magnetic protection by eliminating bending of the tubes inwards due to product flow or handling during cleaning
      • Increases magnet life by preventing broken welds on end of tubes caused by impact during cleaning
  • Detectable Gasket Material
    • Metal detectable magnet housing gasket standard (Buna material)
  • Maximum Pressure Levels
    • Designed for operating at up to 150 PSI maximum pressure (at 248°F) depending on model size
  • High-Temperature Rating
    • Designed for operating temperatures up to 356°F depending on model configurations
  • USDA Certified
    • USDA approved certified sanitary (USDA AMS NSF / ANSI / 3-A14159-1 2002) available

The tramp metal collects at the downstream side of the magnetic tubes, preventing tramp metal “wash-off” during the continuous product flow around and through the magnetic field without restricting the product flow. Additionally, non-magnetic particles are trapped, by gravity, in a sump beneath the magnetic element.
