3. Overview, functional description
means of a cycle indicator or piston detector.
Optional integrated check valves integrated
offer high functional reliability (at high or dif-
fering back pressures). They also provide ac-
curate 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 main metering device/secondary meter-
ing device systems, check valves must be
used on the metering device outlets of the
main metering device.
For the VPKM and VPKG progressive meter-
ing devices, metering device sections for
two connections (T = twin) or for one con-
nection (S = single) are available. In case of
single sections, the two opposite outlets are
connected internally, whereby one outlet is
closed.
For the VPK metering device, it is also pos-
sible to consolidate two neighboring outlets
after the metering devices have been com-
pletely installed.
A progressive metering device of the series
VPK consists of at least three to a maximum
of ten metering sections.
