Feinstfilter MicroPur - KNOLL Maschinenbau GmbH

Application

The MicroPur® is a reverse-flow filter for separating the finest impurities from cooling lubricants (oils and aqueous solutions).

• Ideal for tool grinding in carbide and HSS
• Local use for a machine as a standardised individual system
• Central use for multiple machines as an individual central system
• For cooling lubricant maintenance in the bypass flow

Description

Filtering process

  1. The filter pump conveys the dirty cooling lubricant tangentially into the filter bowl
  2. Centrifugal force causes larger solids to accumulate on the housing wall
  3. The cooling lubricant flows through the filter elements from the outside to the inside
  4. A filter cake (concentrate) forms on the surface of the filter element and acts as an additional deep-bed filter aiding microfiltration
  5. The filtered cooling lubricant (filtrate) enters the clean tank

 

Regeneration process

  1. The growing filter cake causes a reduction in the volumetric flow or an increase in the pressure differential at the filter cartridge
  2. The regeneration phase starts in response to pressure or time control: The intake valve closes and the drain valve opens
  3. The flushing pump conveys the cooling lubricant that has just been cleaned to the filter element, from the inside to the outside
  4. The filter cake is released and enters the sludge tank
  5. Downstream equipment for sludge treatment (automatic concentrator) further reduces the concentrate and conveys it to an external container
