Multi-line system
In most manifold systems, lubrication is provided by a direct connection from the pump to the point.
Therefore, one pumping element is used per point. From a system design point of view, this is the easiest and most intuitive system. If the lubrication amount is different for each point, different elements are used to adjust the amount according to the pumping element's different discharge amount.
Therefore, monitoring equipment is rarely used, but sometimes a distributor valve is used as needed.
