Pump units of the KFG, KFGS and KFGC series for rotary application
31-3034-EN
KFG pump unit
The KFG pump has three lubricant outlets for
connecting up to three independent zones. A
separate pump element is required for each
outlet.
Up to five pump elements with different deliv-
ery volumes are available so the delivery rate
can be adjusted to the requirements of the
individual zones.
Pumps of the KFG series for rotary application
differ from those for industrial use in that
they integrate a patented grease follower sys-
tem. This ensures continuous grease supply
to the pump in every situation.
The pump fill level is monitored by a fill level
switch attached on the cover. Depending on
the switch design, 1 to 3 switching points can
be monitored. "T" control can optionally be
used to provide a continuous fill level signal.
The pump is available in various voltage de-
signs.
There may be restrictions on the components
depending on the particular conditions in the
field of application.
This also applies to KFGS and KFGC (CAN bus)
pump units.
KFGS pump unit
Pump units of the KFGS series are reservoir
pump units with an integrated control unit
based on the KFG.
The KFGS pump unit is controlled by the
IG502-I integrated control and monitoring
unit, which can operate based on time or
(pulse) load and with or without a monitoring
function
.
This control unit provides the following
advantages:
Non-volatile memory with PIN code •
protection
Recording of remaining intervals and •
remaining lubrication times
Recording of fault notifications (diagnostics •
memory)
Data backup in case of voltage failure•
Connectivity for external pushbutton•
Connectivity for inductive piston detector •
or pressure switchInterval time and contact
time can be adjusted independently, inclu-
ding on monitored systems
Easy electrical connection using plug •
connectors
Interval times (timer), interval pulses (coun-
ter) and pump cycle times (contact) can be
entered through a display. A piston detector is
used to monitor the feeding operation on pro-
gressive systems; a pressure switch is used
for single-line systems. The KFGS pump unit
is available in various reservoir and voltage
designs.
In addition to the fill level versions that are to
be attached by the customer, the signal on
switch version "E" can also feed into the
IG502-I control and monitoring unit that is
integrated into the pump.
KFGC (CAN bus) pump unit
Pump units of the KFGC (CAN bus) series are
pump units from the KFG series with an inte-
grated CAN bus control unit.
The LC-CAN5000 control units offer the
following special features:
CAN bus interface (SAE J1939), which •
allows units to be seamlessly integrated
into the CAN bus networks.
The lubrication system can be monitored, •
operated and configured through the
CAN bus.
There is also the option of configuring and in-
dependently operating the pump unit via the
IRDA interface.
The control unit is still able to control up to
four independent zones and to supply them
from a single pump unit. To achieve this capa-
bility, electric switch valves which are con-
trolled based on the parameters set for each
individual lubrication zone are placed in the
main line. The control unit has up to four so-
lid-state switching outputs for this purpose.
Aside from valve control, the outputs can also
be configured as digital outputs for other pur-
poses. In addition to the above-mentioned
outputs, up to four digital inputs are available,
e.g. for monitoring piston detectors, pressure
switches or other switching contacts.
