Distribution block and metering units
Various types of metering units with the Twin greasing system are available, each with a different
grease output. Each grease point can receive the correct dose of grease per greasing cycle by a
careful choice of the type of metering unit.
Figure 2.7
Distribution block with metering units
The metering units are mounted on a distribution block per group. The distribution blocks are
deliverable with 2, 3, 4, 5, 6, 7, 8, 9, 12, 14, 18, 20, 21 or 22 ports (exits).
Grease points are connected to these ports through metering units and secondary grease lines.
Unused ports are sealed with a blind plug. A pressure switch can also be mounted into one of the
ports.
Because of their closed construction the metering units are exceptionally well suitable for use in
dirty and dusty environment.
The metering units and distribution blocks are made of brass or stainless steel. The various metering
units are distinguished from each other using numbers (see Figure 2.7/3). The table below is an
overview of the various metering unit numbers and their grease capacity.
