Multi stage ultrafine filtration plant
Feinstfilteranlage
Processing of coolant and lubricant
LEHMANN – UMT GmbH
Processing of coolants and lubricants
After many successful years on the market, the ultra-fine filter system has been continuously further developed and designed for new materials such as HSS and ceramics, so that users now have state-of-the-art, reliable technology available to filter oils and emulsions crystal clear. The product features are convincing: a combination of different filtration stages allows mixed processing of complicated materials (like HSS, carbid metal, ceramics), the modular design allows configuration and adaptation to a wide range of applications such as grinding, lapping, honing and others.
High-performance pre-filtration by means of magnetic separators and belt filters reduces the dirt load on subsequent filtration stages, which considerably extends their energy efficiency and longevity. Depending on requirements, a lamella separator and a sedimentation tank with discharge system follow. Ultra-fine filtration completes the high-performance filtration system, with which filter finenesses of 2 µm can be achieved. A further advantage that should not be underestimated is the low space requirement of the systems, which is 50 % less than with systems previously available on the market.

Conveying equipment and systems
Chip redistributor
The chip redistributor is a system for the discharge of different chips, e.g. from mechanical processing. The incoming chips are discharged from the workstation by means of a chip conveyor system. The chip redistributor is designed to distribute the conved chips into several containers.

Advantages:
-environmetally friendly separation of the chip waste
-container replacement without idle times
-fast and environmentally friendly proposal of the chip waste at the workstation
