- Conveyor and Filtering System (Pump Technology)



Areas of application: The circuit system is suitable for the fully automatic return of the chip/cooling-lubricant mixture of several processing machines to a central separator/filter. This central separator/filter supplies the machines with cleaned cooling lubricant. The system is used in large production areas with a machine train of 30 and more machines and as an island solution (wet processing).


  • High flexibility in the erection or changeover of the machine train
  • Low space requirement due to above-floor pipelines
  • No plant components within the hall floors
  • Low maintenance and upkeep
