4.3 KFG (S) (L) (C) pump element series
KFG pump units can be equipped with up to
three pump elements.
Depending on the pump unit's application
(ProFlex/MonoFlex) and configuration (KFG/
KFGS/KFGL/KFGC), it is possible to connect
each of the pump elements to a single, inde-
pendent lubrication zone and/or to link them
together to form a shared zone.
The pump elements are available in two types
of design: with spring return pistons or posi-
tively driven pistons.
In both types, the pistons are actuated by a
cam disc. In the spring return design, the pis-
ton of the pump element is pressed against the
cam disc by a spring. In the positively driven
design, on the other hand, the piston of the
pump element is slotted into the cam disc,
which is especially practical when the unit is
used at very low temperatures.
The pump elements are available in different
models for different delivery rates.
A grease return or a filler socket can be at-
tached in place of a pump element. A screw
plug (DIN 910-M20x1.5-5.8) with sealing ring
(DIN 7603-A20x24-Al) can also be fitted if de-
sired. Alternatively the screw plug can be
ordered from SKF under order number
KFG 1.128.
