PSG3 modular dosing units

For sequential or circulating oil lubrication systems

The PSG3 consists of a support panel and various metering segments that can be combined to create the desired output ratios. The channels are integrated into the support panel, so the connections and tubes remain in place even if individual segments need to be replaced.

Technical characteristics and advantages

  • Easy to maintain as the outlets are located on the support panel
  • Design flexibility thanks to replaceable dosing segments
  • Optional visual or electrical monitoring
  • Versions made of material with improved corrosion resistance are available
  • Blind segments are available
  • Adjustable supply thanks to internal or external connection of outputs
  • The main metering device in circulating oil lubrication systems

Application areas

  • Tunnel boring machines
  • Papermaking machines
  • Presses
