SKF KFGL - KFGS Pump Units; KFGL Pump Units

5.4 KFGS pump units
Pump units of the KFGS series are reservoir
pump units with an IG502-2-I integrated con-
trol unit with a control display. Parameters for
interval times (timer), interval pulses (counter)
and pump cycle times (contact) can be entered
through the control unit.
A piston detector is used to monitor the feed-
ing operation on progressive systems.
The KFGS pump is available in the same reser-
voir capacities and voltage designs as the KFG
series.
The fill level of the pump units is monitored
using the fill level switches mentioned in
Chapter 5.2.3 (operating instructions) and
Chapter 4 (in the assembly instructions).
The signals from minimum fill level monitoring
are processed by the integrated KFGS control
unit.
5.5 KFGL pump units
Pump units of the KFGL series are reservoir
pump units with an LC502 integrated control
unit with a control display. The control unit is
pre-programmed with standard settings and
easy to operate
The control unit can be used to set the pump
run time either:
based on pump speed
 based on time (hours and minutes) or
machine cycles (load-dependent)
Sectional lubrication is available for differing
lubricant requirements; the lubrication lines
can be controlled and monitored individually
The LC502 also offers a wide range of options
for monitoring functions and processes, with
up to three lubrication zones able to be moni-
tored independently.
The LC502 is fitted with integrated tempera-
ture overload protection and continuous sys-
tem monitoring with fault detection and fault
analysis.
A piston detector is used to monitor the feed-
ing operation on progressive systems; a pres-
sure switch is used for single-line systems.
The KFGL pump is available in the same reser-
voir capacities and voltage designs and with
the same grease follower plates as the KFG/
KFGS series.
The fill level of the pump units is monitored
using the fill level switches mentioned in
Chapter 5.2.3 (operating instructions) and
Chapter 4
(in the assembly instructions.
The signals from minimum fill level monitoring
are processed by the integrated KFGL control
unit.
