Which one Batter Parallel or Progressive CLS?

To know which one is better, I think you first need to know how both of its work. It is obvious that both do the same work that is Supply of Lubricant to the required place, But the working principle is completely different.

A. Single-line (parallel) system CLS:

          A single-line parallel system is the simplest automatic lubrication system. A pump pressurizes the main supply line and fills several individual piston distributors or injectors. Each injector serves one lubrication point and can be easily adjusted to deliver a precise amount of lubricant with a high degree of accuracy. The injectors operate independently of each other. The advantage of this is that failure of an individual injector, or a blocked supply line, does not disrupt the rest of the system.

   B. Series (Progressive) system CLS:

             In a series progressive system, a pump supplies the lubricant through a master metering valve and optional secondary metering valves to the lubrication points. The metering valves are custom-sized for each lubrication point to deliver the required amount of lubricant. Each piston inside a divider, block is dependent on the flow of the previous piston. Lubricant is therefore delivered to each lube point in succession. This means that if lubricant reaches the final lube point in the network, you know that each point in the network has received its specific amount.

                 So, now the question is who works batter, Based on my hand on experience I can Conclude that Progressive CLS is definitely battered then Parallel one Because of the advanced process/ Technology used here. Progressive can work in high pressure, MLS installed so you can monitor properly, Less maintenance is required.
