Functional description of progressive
system with KFG pump unit
A general progressive feeder system con-•
sists of the following components: Pump
unit with pump element and pressure
regulating valve
Lubricant lines, consisting of main and •
possibly branch lines
Progressive feeders •
When the pump motor is turned on, the pis-
ton pump delivers lubricant from the lubricant
reservoir to the lubricant outlet. The pump el-
ement attached to the outlet delivers the lu-
bricant further, into the downstream main
line. The lubricant flows through the main line
to the progressive feeder. There, the lubricant
is distributed according to the volume re-
quired by the lubrication point being sup-
plied.
In progressive systems with a master feeder
and secondary feeder, the lubricant coming
from the pump unit is delivered to the master
feeder. The master feeder distributes the
lubricant to the secondary feeders according
to their individual volume requirements. From
there, the lubricant flows to the lubrication
points.

Functional description of progressive
system with KFGS pump unit
The general functional description for progres-
sive systems with a KFG pump unit also ap-
plies for the design with KFGS pump control.
The control unit integrated into the pump
housing allows the following additional con-
figuration, monitoring and connectivity op-
tions:
Interval time and contact time can be •
adjusted independently, including on moni-
tored systems
Recording of remaining intervals and •
remaining lubrication times
Data backup in case of voltage failure•
Non-volatile memory with PIN code •
protection
Connectivity for inductive piston detector to •
monitor the feeder function
Connectivity for external pushbutton •
Internal fill level monitoring (E control); •
lubrication cycle and fault notification
remain on display in case the level falls
below minimum

Functional description of progressive
system with KFGC (CAN bus) pump
unit
The general functional description for pro-
gressive systems with a KFGS pump unit also
applies for the design w ith CAN bus pump
control. The integrated LC-CAN5000 control
unit permits the lubrication zone of a pro-
gressive feeder system to be distributed into
individual lubrication zones for which individ-
ual parameters (e.g. contact and interval
times) can be set. Up to four lubrication sec-
tions can be installed in total. To distribute the
lubricant, a corresponding number of electric
switch valves is installed in the lubricant line
leading from the pump element. A valve is
opened as soon as the control unit starts a
pump cycle period for the corresponding lu-
brication segment. The pump can only pro-
vide one lubrication segment with adequate
lubrication, so it must be ensured that only
one valve is opened during operation. This is
handled by the control unit in automatic and
semiautomatic operation.
A 5/4 directional solenoid valve can optionally
be used in place of single valves.
