Liquids & powders in food & pharma pressure lines
This type of magnetic filter is especially designed for the high hygienic requirements of the food and pharmaceutical industries. The products to be transported are usually liquids or powders with a risk of bacterial growth.
Suited for pressures up to 10 bar and temperatures up to 140 °C.
We can calculate the precise pressure drop with these filters in your situation for gaseous or liquid products using our FEM software. The pressure drop depends on the physical properties of your product flow (viscosity) and its speed. Please contact us about this.

Filtering & discharging of ferrous impurities
The magnetic unit with very strong neodymium magnetic bars is positioned in the middle of the product flow. The product with ferrous impurities passes several magnetic bars while flowing through the filter.
The magnets attract passing ferromagnetic contaminants. The captured particles stick to the magnets, while the purified product flows further.
How does the cleaning / iron discharging work?
Once the product flow is stopped, you take the entire magnetic grid unit out of the product channel. Then pull the magnetic bars out of the extractor tubes, causing the ferrous particles to fall off the extractor tubes.
Cleaning / iron discharging sequence
- Stop the product flow.
- Unscrew the clamp connection of the magnet unit.
- Lift the complete magnet unit out of the housing.
- Take the magnet unit out of the extractor unit and place it away from the extractor unit on a clean surface.
Catch the ferrous particles that now will fall off the tubes and dispose them.
- Wipe clean all parts with a soft cloth and - if necessary - a suitable cleaning fluid.
- Shove the magnet unit back into the extractor unit.
- Place the complete magnet unit assembly back into the housing.
- Replace the clamp and re-tighten it by tightening the screw connection.
- Restart the product flow.
