High pressure unit LubiCool - KNOLL Maschinenbau GmbH


The KNOLL high pressure unit LubiCool®-L is a compact high pressure unit for machine tools, particulary for small and medium machining centers and lathes. The system cleans the CL and provides the machine with high pressure.

It is suitable for

  • Demanding machining processes
  • Machining difficult materials (e.g. high-alloy steels, titanium, copper)
  • High pressure requirements with increased volume of CL
  • Additional flushing requirements
  • Original equipment and retrofitting



Compact and modular

• Space-saving installation
• Flexible and demand-driven configuration


• Fast installation
• Easy retrofitting

High pressure up to 90 bar with optional flushing

• Short-breaking chips
• Reduced processing times due to higher cutting speeds
• Extended tool life
• High flushing performance

Effective filtration via belt filter

• Reduced concentration of ultra-fine particles
• Long service life of components and the cooling lubricant (CL)

Wear-resistant screw spindle pump

Long service life and process reliability

Demand-driven pump control

• Lower energy costs
• Lower heat development
• Longer durability

Attractive price-performance ratio

Short amortization time


  1. The transfer pump or the lift pump of the chip conveyor conveys the dirt CL from the machine tool into the compact filter.
  2. The compact filter separates chips and the soiling from the CL, which flows in the clean media tank.
  3. The dirty fleece is collected in the sludge container.
  4. The high pressure pump provides the machine tool demand-driven with cleaned CL through switchable outputs. 
  5. The optional flushing pump can operate different flushing processes via up to four switchable outputs. 
  6. The SmartConnect control takes over control, monitoring and visualization of the system parameters.
