The Magnetic Liquid Trap is a precision-engineered magnetic filtration device built for liquid, semi-liquid, and air-conveyed dry material pipelines. Produced by Mag Spring®, this system ensures reliable removal of ferrous contaminants, protecting pumps, valves, and finished products across food, chemical, and fine-powder conveying industries.
Four Configurations to Match Your Process
The Magnetic Liquid Trap Separator features a robust 304 / 316L stainless-steel housing with full-welded, leak-proof construction. Inside, high-intensity Neodymium magnetic cores generate up to 12,000 Gauss in standard models — and up to 14,000 Gauss for special . Also,special high-temperature(more than 300 °C engineered for demanding processes.
It comes in two main types:
Standard type: for typical liquid and slurry systems.
Easy-clean type: with a quick-release magnetic core for fast maintenance and reduced downtime.
The advanced magnetic circuit captures fine ferrous particles down to sub-micron size, ensuring product purity and minimizing wear in downstream equipment.

Engineered for performance stability, the trap’s durable body structure provides pressure resistance up to 10 kg if needed, allowing safe operation even in sealed pipelines and pneumatic powder conveying systems.
The high-temperature magnetic trap model maintains strong magnetic performance at temperatures exceeding 350 °C, ideal for thermal processing lines, paint, or resin industries where heat resistance is critical.
High-Pressure Magnetic Liquid Trap for Industrial Slurries
To integrate easily into various industrial setups, the Magnetic Trap Filter offers flexible connection options:
Tri-Clamp (sanitary) — for hygienic food and beverage production.
Threaded (BSP/NPT) — for general industrial lines.
Flanged — for heavy-duty or large-volume piping systems.
This adaptability makes it a top choice among high-pressure magnetic liquid filter solutions requiring both precision and durability.
During operation, the process fluid passes through a chamber containing high-intensity magnetic rods. Ferrous impurities are attracted to the rod surface while the purified liquid or gas continues downstream.
In easy-clean models, users can remove the magnetic assembly, discharge captured metals, and quickly resume production — improving maintenance efficiency and reducing contamination risk.

The Magnetic Liquid Filter for Pipeline Systems is widely used in:
Food & Beverage: chocolate, syrup, sauce, and dairy lines.
Chemical processing: paint, resin, pigment, and additive filtration.
Pneumatic powder transport: dry fine powder systems that require airtight design to prevent leakage.
Pharmaceutical and cosmetic: sanitary filtration in liquid and semi-liquid materials.
Our magnetic liquid traps meet the rigorous hygiene standards of the global food and dairy industry.
⚠️ Note: This model is maybe not suitable for sticky or bridging-prone liquids that require heating to stay fluid. For such materials, see our Insulated Magnetic Separator for Hot Viscous Liquids.
