Key Observations:
• Pressure drop increases non-linearly with higher flow rates (typical for basket strainers).
• Magnetic efficiency remains very high (>95%) at moderate flow rates and gradually decreases at very high velocities due to reduced residence time.
• Data is based on clean water at 20°C for a standard 4″–6″ model with 12,000 Gauss neodymium magnets.
✦ Optimal operating range: 20–40 m³/h for best balance of low pressure drop and high magnetic efficiency ✦

Step-by-Step Installation Procedure
| Step |
Procedure |
Notes |
| 1 |
Verify the strainer orientation – arrow on the housing must point in the direction of flow. |
Incorrect orientation will reduce efficiency. |
| 2 |
Install the unit in a horizontal or vertical position with adequate clearance for basket removal (minimum 1.5× basket length above or in front). |
Allow space for future maintenance. |
| 3 |
Place gaskets between the strainer flanges and pipeline flanges. Align bolt holes carefully. |
Use new gaskets only. |
| 4 |
Insert bolts and hand-tighten in a criss-cross pattern. Then torque to manufacturer-recommended values using a torque wrench. |
Avoid over-tightening to prevent gasket damage. |
| 5 |
For threaded connections: Apply PTFE tape or thread sealant and tighten securely. |
Do not overtighten threaded ends. |
| 6 |
Install the magnetic rods into the housing and secure the cover tightly. |
Ensure magnets are fully inserted. |
| 7 |
Slowly pressurize the system and check for leaks at all connections. Tighten if necessary. |
Monitor pressure gradually. |

Step-by-Step Maintenance Procedure
| Step |
Procedure |
Important Notes |
| 1 |
Shut down the system, isolate valves, and depressurize completely. Drain all fluid from the strainer. |
Lockout/Tagout must be applied. |
| 2 |
Remove the cover carefully. Pull out the magnetic rods and inspect captured ferrous debris. |
Golden-yellow rods make debris highly visible. |
| 3 |
Remove the basket strainer. Clean thoroughly with a soft brush or non-metallic scraper. |
Do not use metal tools on the basket. |
| 4 |
Wipe magnetic rods with a clean cloth. Remove all attached ferrous particles. |
Strong magnets – keep away from metal tools. |
| 5 |
Inspect seals and gaskets. Replace if damaged or hardened. |
Use compatible gasket material. |

Q&A
| Question |
Answer |
| What is the main advantage of a Magnetic Filtration Basket Strainer compared to a standard basket strainer? |
It provides dual-stage filtration: the basket removes large debris and non-ferrous particles, while the high-strength neodymium magnets capture fine ferrous contaminants down to 1 micron that would otherwise pass through a standard strainer. |
| How fine can the magnetic filtration capture particles? |
The powerful neodymium magnets can effectively capture ferrous particles as small as 1 micron. The basket strainer rating typically ranges from 50 µm to 5000 µm depending on your selected mesh or perforation. |
| What materials is the strainer made from? |
The housing and basket are constructed from high-quality Stainless Steel 304 or 316L, offering excellent corrosion resistance and suitability for industrial, chemical, and food-grade applications. |
| How do I know when the strainer needs cleaning? |
Monitor the differential pressure across the strainer. A significant increase in pressure drop indicates clogging. The bright golden-yellow magnetic rods also make captured ferrous debris highly visible during inspection. |
| Can the magnetic rods be removed for cleaning without stopping the entire process? |
No. The system must be isolated and depressurized before removing the cover and magnetic rods. This is a standard safety requirement. |
| What is the maximum operating pressure and temperature? |
Standard models are rated up to 16 Bar (232 PSI) and temperatures from –20°C to +150°C (–4°F to +302°F). Higher ratings are available upon request. |
| How often should maintenance be performed? |
Frequency depends on contamination level. Typical schedule:
• Magnetic rod cleaning: Monthly
• Basket cleaning: Every 1–3 months
• Full inspection: Every 6–12 months |
| Is this strainer suitable for food or pharmaceutical applications? |
Yes. When ordered with 316L stainless steel, sanitary tri-clamp connections, and food-grade gaskets (EPDM or PTFE), it meets requirements for food, beverage, and pharmaceutical processes. |
| Does the magnetic filtration affect non-ferrous particles? |
No. The magnets only attract ferrous (iron, steel, nickel, etc.) particles. Non-ferrous contaminants are captured solely by the basket strainer mesh or perforations. |
| Can the strainer be installed in any orientation? |
The flow direction must follow the arrow marked on the housing. It can be installed horizontally or vertically, but sufficient clearance must be provided for easy basket and magnet removal during maintenance. |

Suitable for oils, coolants, chemicals, water, and food-grade liquids. |
Magnetic strength can weaken over time
Extreme temperatures or physical damage may reduce magnet performance. |
✦ Overall, the advantages in filtration performance and equipment protection far outweigh the disadvantages for most industrial applications. ✦
