Flowline Oil Supply Units

Screw pump unit for oil circulation systems

SKF Flowline oil supply units provide highly efficient separation of lubricant from water and air. Cylindrical stainless steel reservoirs typically require only a third of the volume of traditional oil tanks. Advanced technology and the unique SKF reservoir design maintain the oil at the highest level.

The SKF Flowline series compact modular circulation lubrication system consists of the following components:

  • Flowline pump unit
  • Control Center ST-2240
  • Flowline flow meters
  • Oil collectors

Technical characteristics and advantages

  • Increased operational availability thanks to optimal oil transport
  • Reducing costs for purchasing, transporting and disposing of oil
  • Energy saving
  • Reducing the negative impact on the environment
  • Reduction in tank size by 50 % compared to conventional oil tanks
  • Air and water removal efficiency is 80 % higher than conventional oil tanks
  • Improving the efficiency of the 90 % tank
  • Short delivery times

Application areas

  • Pulp and paper industry
  • Metallurgy
  • Mining industry
  • Industrial gearboxes
  • Industrial fans
