Dual-Line Lubrication Systems

Dual-line lubrication systems are centralised networks that alternately pressurise two main lines to operate positive metering valves. The alternating action supports many outlets over extended plant layouts and allows feeder output to be adjusted for heavy machinery using grease in demanding environments.

Questions about dual-line lubrication systems

What should I send to identify dual-line lubrication systems?

Send point count and outputs, piping distances, grease grade, reservoir capacity, reversing and monitoring method. Send a plant layout showing both line routes and each feeder, including the most remote point and elevation changes. A clear photograph, drawing or readable reference can resolve details that dimensions alone do not show.

How should I select dual-line lubrication systems?

Design both mains, pump, reversing valve and feeders from distance, grease flow, ambient conditions, point demand and control philosophy. Confirm the mating parts and operating environment before ordering, since an apparently similar size can use a different profile, material or internal arrangement.
