Dual Line Systems & Multi Line Systems

When there are no of points in a machine which require to be lubricated the options are to have a centralized lubrication system which may be a
* Radial pump
* Pump with Progressive Type system
* Pump with Dual line System
* Mist lubrication /Spray system
* Single point lubricator

Dual line systems are used for plants and equipment generally where the points between each other is large. This system makes it possible for parallel installation. These systems have their applications compared to the progressive type system. The difference apart from this being a parallel line installation is that it requires change over valves to change the flow of lubricant from one line to other. However, individual flows can be adjusted for each point in this system.
