Centralized lubrication systems withprogressive distributors preferably serve the lubrication of machinery. The lubricationcapacity is up to hundreds lubrication points per system.

Progressive distributors distribute thelubricant to the lubrication points connected to their outlets, in smallmetered quantities progressively in a given sequence. When the last lubricationpoint has been supplied, the process of lubrication automatically starts againat the first lubrication point. If lubrication is interrupted at any point,because the pump is switched off or the delivery line is blocked, it continues fromthe same point when the system is re-started.
