In a progressive system the lubricant is pumped into a single input of a "progressive distributor" and is volumetrically divided into a number of points by the progressive movement of the pistons arranged in sequence.
The valves of the distributor are in series with each other, that means that each piston can supply the lubricant only once the previous one has completed its dosing. An obstructed dispensing point, or a faulty component, will cause the end of operation of all connected progressive distributors. A sensor will signal the alarm, and is necessary only to check a single element to detect the fault in the line block.
One of the major advantages is that allow more control over the correct operation of the entire system and individual outlet points, not just the oil level and the correct operation of the pump.
The new system will then be managed with a new logic based on two different processing parameters of the conveyor, both empty and full.
