This D25 x 150mm Magnetic Rod has a threaded M8 Hole, with an outside diameter of 25mm and a length of 150mm. It has a high Gauss reaching 12,000. These magnetic filter rods are used for continuous removal of ferrous debris, ensuring product purity and subsequently protect the downstream equipment from being damaged. From large magnetic separator systems to small single drawers these rods are able to extract any ferrous contaminant.

 

The magnetic rods (magnetic bars) are composed of stainless steel tubes and rare earth magnets inside (normally neodymium magnets, specially SmCo magnets for higher working temperature). The surface of magnetic rods can be fine polished and meet the food standard and pharmacy industry standard. The working temperature is depended on the magnets used inside.
 

1. Standard diameters D12, D16, D18, D19, D20, D23, D25, D32mm. Smallest can be D6mm and can be bigger than D35mm for customization.
2. Length can be up to 1,000 mm and even longer per customers' requirements.
3. Standard fixation with female threads of M6, M8, M12 or male threads of M6, M8, M12, or inch threads according to customers' requirements.
4. Customized designs are welcome
5. Laser welding and normal welding (argon protecting welding) optional.
6. Easy to assemble/remove the tubes with the standard threads on the tube' ends on/from the frame.
7. Maximum flux density can reach 12,500GS on the rod surface
8. Application:  Food industry / Dairy industry / Chemical industry / Water treatment / Heating solution / Plastic industry / Textile industry / Pharmaceutical industry

Remarks:
1. The SST results differ from coating. In general, Salt Spray Test result for the magnets with barrel plating (normally for small size of magnets), is better than the ones with rack plating (normally for big size of magnets).
2. Salt Spray Test (SST) condition: 5% NaCl, 35°C, continuously spray a certain time, test whether there is corrosion on plating/coating surface.
3. Pressure Cooking Test (PCT) condition: 2 atm, 95% RH (Relative Humidity), 121°C to test the plating/coating adhesion. (Zinc, Passivated/Phosphated, and Epoxy not suitable for PCT).
4. Other test methods for plating/coating: Drop Test, Cross Cut Test, Heating and Spilling Test, Constant Temperature, Humidity Test, etc.
