Interface/connection dim's : DN250 acc. EN 1092-1 PN10
SFN-250-IF-07Q-HT-F1m-S-B-B
SKU: SSFNP25038
Stock *: 0
No of bars: 7
Build-in length: 500 mm
Weight: 130 kg
Robust filter for general industrial applications without risk of bacterial growth.With these large diameters, the filters are too heavy to lift. Therefore, the cleaning is semi-automatic. For magnetic filtering of fine ferrous contaminants - such as stainless steel wear particles - from your liquid and powder flows in pressure pipes up to 10 bar.

Semi-automatic cleaning
Capture Fe particles from 30 µm - 2 mm
Flanges DN150-300 (EN 1092-1)
Max. 10 bar / 140 °C
Magnetic bars in pneumatic tube (Ø34 mm, 9400 gauss)

Application

Liquids and powders in pressure lines up to DN300

This very robust magnetic filter is suitable for many industrial applications where liquid mixtures and powders are transported in pressurized pipelines up to 10 bar.
 
For example removing steel wire from paper pulp (read the news article about this application).

Working princple

Filtering & discharging of ferrous contaminants

How does the magnetic filtering work?
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?
Cleaning of the magnetic rods is partly manually (over guide rods) and partly automatically (pneumatically controlled).
 
Once the product stream is stopped, you pull the complete magnet unit out of the product channel over the guide rods. Then the magnetic rods are pneumatically 'blown' to the OUT position, at which point the Fe particles fall off of the tubes.
 
Cleaning / iron discharging sequence

Stop the product flow
Loosen the srew connections of the magnet unit
Slide the complete magnet unit out of the housing
Slide the magnet unit out of the extractor unit
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
Slide the magnet unit back into the extractor unit
Slide the complete magnet unit assembly back into the housing
Re-tighten the screw connections
Restart the product flow
