Description

Dosers are lubrication elements designed for two simultaneous supply lines, one of which is pressurized while the other is depressurized, alternating lubrication cycles thus dosing an adjustable amount of lubricant in each cycle.

Design and principle of operation

Each dosing unit is made up of a servo piston (A) and a servo (B). The movements of the piston (Fig. 1) show the operation of the dispenser alternating the feeding of the lubricant when it enters through line 1 or when it enters through line 2.

The supply is made with the two separate outputs, but there is the possibility of internal communication of the outputs, unifying in a single output, thus doubling the flow. It has two possibilities, through internal or external communication.

  • Internal communication, is done online and opposite outputs are communicated. It consists of removing the stopper (C) and extracting the ball from its interior (D). (Fig. 2)
  • External communication, outputs can be joined in line and is done by means of two additional parts on the outside, the union block (F) and the ogive (E). (Fig. 3)

Being internal communication, we offer the advantage of avoiding fittings and external piping, thus favoring a clean installation.
