Progressive metering
type a | b | c | d | e

At preset interval of times, pump EUR 1 supplies grease to the meters, which are responsible for determining the correct amount of grease that has to be supplied to the lubricating points.

However, as the mechanical organs do not require the same amount of lubricant, the flow rates of meters have been adjusted in order to meet the requirements of all possible applications.
The amount of grease supplied by each meter can be easily determined by observing the lines engraved on the brass body of the meter.

The amount of supplied grease depends on the actual stroke of the small piston of the meter.
The position of the elastic ring is used to adjust the stroke of the piston or, in other words, to increase or reduce the delivered volume of grease. The grease coming from the dispenser is pressurized.

When the piston is pushed down towards the bottom of the cylinder, it forces the grease volume in the chamber below to move towards the plastic tube and reach the lubrication point.

The meter reloads the grease leveraging the pressure difference generated by the pump. The ball closes the delivery duct so that when the piston returns to its idle position, it moves the grease from
upstream to downstream, thus preparing for the next lubrication cycle.
