Tube Liquid Trap Magnet
Purification of Liquids and Wet Separation
MPI’s Liquid Finger Trap Magnet Tube Design (LFT) — is designed to protect product flow lines and pumps by magnetically removing ferrous contaminants from product flow. MPI’s Liquid Finger Trap Magnets Tube Design magnets provide purification of liquids and wet separation for a variety of industries, including, but not limited to, chemicals, food processing and paper mills.
Benefits of the Tube Liquid Trap Magnet From Magnetic Products, Inc
- 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.
- Diameter Ranges
- Standard inlet / outlet sizes available from 1.5” diameter up to 12” diameter (HP model required for sizes over 4” diameter)
- Adaptable to Existing Lines
- Easy installation into existing line using sanitary tri-clover, threaded or ANSI 150 pound inlet and outlet flanges
- Tube Configuration for Easy Cleaning
- Exclusive tube configuration for easy removal of ferrous tramp metal from magnetic tubes
- 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
- Welded tube support located on the bottom of the magnet element
- 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
Tube Liquid Trap Magnet Product Details
How It Works
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.

Product Options
- Pipe Size: Available in diameters from 1” to 6” in any increment.
- Maximum Operating Pressure:
- 150 PSI at 248°F (120°C) (standard on sizes 4” and smaller)
