Magnetic filter - The environmentally friendly filter solution

We are taking energy efficiency to a new level. The magnetic filter enables the efficient removal of large dirt loads from the process with minimal energy consumption. Thanks to the high efficiency of our system, you achieve considerable cost savings and increase the efficiency of your processes, while reducing component wear to a minimum. The result is a dry filter cake, minimizing the carryover of cooling lubricants from your process.

    The magnetic filter works in a very small installation space with a strong permanent magnet in the form of a permanent magnet roller, which is encased in a stainless steel shell. Thanks to a special rotary movement, the system reliably removes large amounts of dirt. The magnetic filter does not require any filter consumables for the filtration process and is therefore extremely sustainable and cost-efficient. The system is equipped with a plastic roller that presses out the resulting filter sludge, minimizing the carryover of cooling lubricants and creating a dry filter cake. Thanks to our intelligent design, you benefit from the long service life (4 to 6 years) and longer maintenance intervals. This leads to the high profitability and investment security of our systems. The magnetic filter system from Lehmann-UMT can be used in combination with all other filter systems either as a pre-separator or as a main filter.

    The magnetic filter is a compact system and consists of a strong permanent magnet roller, which is encased in a stainless steel shell. The magnets in the roller are mounted in such a way that they repel each other, maximizing the magnetic fields in the throughput depth. This enables even the smallest ferromagnetic particles to be reliably discharged.

Properties

The system is able to remove large quantities of dirt, helps to reduce wear on downstream filter systems and requires minimal space. The liquid enters the magnetic system from above through a distribution box. A rake distributes the liquid evenly so that it runs homogeneously past the underside of the magnetic roller. This ensures effective and safe filtration.

The roller rotates against the flow direction of the liquid, so the ferromagnetic particles adhere to the roller and are discharged from the process by the rotational movement. At the top of the magnetic roller there is another roller made of plastic, whose task is to press out the ferromagnetic particles and keep the liquid in the system. This process produces a dry filter cake or filter sludge. With our system, you reduce production costs by being able to recycle the filter cake more easily, reduce the disposal volume and minimize the carry-over of cooling lubricants.

By using magnetism, a naturally occurring energy source in the environment (magnetism), our system is characterized by its exceptional energy efficiency, sustainability and cost effectiveness. Furthermore, it does not require any filter aids or consumables, significantly reducing disposal volumes and operational costs. Thanks to its long service life, the magnetic filter achieves a positive ecological balance while ensuring high machine availability.

The system is made of stainless steel as standard, which makes it corrosion-resistant and also covers processing areas in acidic or alkaline environments. With our magnetic filter, you are flexible and securely positioned for the future.

Technical details:

  • Filter capacity: 60-1,600 l/min
  • Filter fineness: serves to reduce the dirt load of magnetic particles

Advantages

  • High dirt loads with minimal energy consumption

    The magnetic filter removes large quantities of dirt with minimal energy input and ensures efficient and cost-effective filtration, a short amortization period and high profitability. By using natural energy found in the environment (magnetism), the system requires only minimal auxiliary energy for filtration and reduces your production costs.

  • Sustainability

    The magnetic filter is particularly sustainable thanks to its long service life, low wear, high efficiency and energy efficiency. In addition, no filter aid is required for filtration, which reduces your production and follow-up costs. Move into a sustainable future with us.

  • Long service life / service life

    The magnetic filter is characterized by its durability and service life of 4 to 6 years. You benefit from outstanding machine availability, process reliability and a short amortization period, as the system works reliably over a long period of time. Thanks to its long service life, the magnetic filter is a particularly sustainable system with a positive ecological balance.

  • Long maintenance intervals

    The intelligent design and the high-quality, robust materials of the magnetic filter ensure long maintenance intervals. You benefit from maximum productivity thanks to the continuous operation of the filter. Your personnel costs are reduced thanks to the service and maintenance-friendly design of the system.

  • Efficient maintenance and low wear

    Thanks to the intelligent design and the use of robust, high-quality and durable materials, you benefit from reduced system maintenance and increased productivity. The longer maintenance intervals ensure savings in personnel costs. This increases the overall efficiency of your production, as your employees can concentrate on other important tasks. The entire system is designed to be extremely easy to maintain and service, which means that maintenance work can be carried out quickly and easily by trained personnel.

  • Small footprint

    The magnetic filter is very space-saving and is installed in the smallest possible installation space. This allows you to make optimum use of your available space and gives you more capacity for additional processing machines.

  • No filter consumables required

    The magnetic filter works with a strong permanent magnet, making it highly efficient and effective without the need for additional filter aids or consumables. Benefit from lower production and disposal costs with our system.

  • Fast commissioning and easy integration

    You benefit from time savings, cost reductions and increased flexibility thanks to the standard plug-and-play system. This means that Lehmann-UMT systems are easy to integrate and are quickly ready for operation.

  • Dry filter cake and low carry-over of cooling lubricants

    Dry filter cake and low carry-over of cooling lubricants lead to cost-efficient production, as the cooling lubricant can be used for longer, thereby reducing production costs. The dry filter cake makes it easier to recycle the chips, which has both economic and ecological benefits. With the system, you optimize your use of resources and actively contribute to environmental protection.

  • Automatic and intelligent sensor control

    The compact filter has an automatic and intelligent sensor control system that ensures needs-based filtration so that little manual intervention is required. This reduces personnel costs, machine downtimes and enables efficient filtration without additional manual control. All signals from the filter system are output to the connected processing machine, enabling problems to be identified more quickly and saving costs.

  • Safety and control through intelligent electrical interfaces

    The Lehmann-UMT systems can be flexibly integrated and keep pace with technological progress, thus reducing retrofitting and follow-up costs. You get maximum safety and control, as the compact filter is easily connected to the building management system. Intelligent sensor technology and connection enable early notification of maintenance and service work, which increases your productivity and reduces your costs.
