Piston pump system for spraying the smallest quantities of liquid.

Main application range:

External MQL for circular saws and band saws.

Operating principle:
The liquid flows from the reservoir into a piston pump. This pushes an exact quantity of the lubricant into the internal feed tube. Separately supplied compressed air splits the medium in the nozzleblock into tiny particles of fluid and sprays it onto the tooth profile of the saw.


  • Swept volume of the pump (manual)

  • Clock frequency of the pump (manual)

  • Quantity of spray air (manual)

  • Switch on/off using actuation control drive (electric, pneumatic or manual)

Pump module SF

– Pneumatically driven, finely meterable piston pump with FPM seals, manually adjustable with PMC precise metering control (2), enabling easy adjustment of the volume using a dial.

– Ventilation unit integrated underneath the pump module.

– Frequency generator for pump pulses, manually adjustable 0 – 90 stroke min-1.

– A air valve to enable the quantity of spray air to be adjusted.

– High-grade push in/screw fittings/ pneumatic tubes.

– Stable, compact metal housing (200x200x155) with robust metal closer and door seal for dust protection and noise reduction, earthing pin.



– Connections for feed tube with EASY-COAX® system (plug-in system for speedy, simple assembly, disassembly and interchange, including EASY-COAX® twist-stop) on the left side of the housing.

– Component labelling in accordance with the designations in the pneumatic connection diagram.
