Liquid Fingertrap Tube Magnet

MPI’s Liquid Fingertrap Magnet Tube Design (LFT) — is designed to protect product flow lines and pumps by magnetically removing ferrous contaminants from product flow. MPI’s Liquid Fingertrap 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.

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

Description

How Liquid Fingertrap Tube Magnets Work:

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.

Liquid Fingertrap Tube Magnet 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)
- 75 PSI at 248°F (120°C) (standard on sizes 5” and larger)

Cleaning Method:
- Manual clean (standard)
- Manual quick-clean with a sleeve over stripper for easy removal of tramp metal. Not recommended for sticky products. Sleeve over design reduces magnetic performance at contact.

Magnet Element: Four different styles are available depending on your application
- Array of 1” diameter tubes designed for liquids, purees, and products with solids 1/2” and smaller
- Single 3” diameter tube mounted in the center of housing designed for products with fragments, solids or chucks up to 1” in size
- Plate magnet design with one or two plate magnets mounted on the outside of the product flow for very difficult flowing and fibrous products
- Combination magnet and screen design
