3. Overview, functional description
can be checked by monitoring any piston by
means of a cycle indicator or piston detector.
Check valves integrated standard offer high
functional reliability (at high or differing
back pressures). They also provide accurate
metering and safe blocking behavior, even
for internal and external consolidation of
lubricant outlets.
Progressive metering devices distribute
a lubricant quantity delivered by a pump
to multiple outlets. The individual meter-
ing device sections determine the quantity
distribution.
The different output quantities within a me-
tering device are achieved by using various
metering device sections or consolidating
two or more outlets.
For the VPM and VPG sectional metering
devices, sections for two outlets
(T = twin) or for one outlet (S = single) are
available. In case of single sections, the two
opposite outlets are connected internally,
whereby one outlet is closed. Each section is
equipped with a lateral and an upper outlet
per side. Only one outlet can be connected
at a time. The second outlet must be blocked
by either a plug screw, a blockage indicator,
or a lubricant nipple. If necessary, crossport-
ing bars can also be connected to the upper
outlets.
A progressive metering device of the series
VP consists of at least three to a maximum
of ten progressive metering device sections.

Example: 2S = 0.4 cm³ per cycle from one outlet
3S = 0.6 cm³ per cycle from one outlet
6S = 1.2 cm³ per cycle from one outlet
Example: 2T = 0.2 cm³ per outlet
3T = 0.3 cm³ per outlet
6T = 0.6 cm³ per outlet
Example:
2SC
= 0.8 cm³ per cycle from one outlet

T (twin) = two outlets
