Dual-line lubrication systems
for oil, semi-fluid grease and grease up to NLGI 2
SKF and Lincoln dual-line lubrication systems can be used on large systems with dispersed lubrication points that require varying lubrication quantities. These systems utilize two main lines that are supplied alternately with lubricant from a high-pressure pump via a change-over valve at up to 400 bar (5800 psi). Branch lines, along the main lines, are connected with dual-line metering devices to supply a large volume of lubricant to the lubrication points. Within large dual-line systems, end-of-line pressure switches are used to control and monitor the system.

Benefits and applications
simple to design, easy to extend or reduce
precise, metered amount of lubricant, to up to 2000 lubrication points over long distances up to 120 m
- Variety of applications
heavy industry, metal working plants, pulp and paper production, mining, mineral processing, power plants, cement factories, steel works and more
- Effectively in harsh conditions
including potentially high lubrication-point back pressure, dirty, wet or humid environments and low temperatures.
