4.3.1 KFG/KFGS pump elements
KFG and KFGS pump units can be equipped
with up to three pump elements. Each pump
element has a connector for, e.g., connecting
an independent progressive feeder. A grease
return can be attached in place of a pump
element.
Close any outlets which are not required using
a DIN 910-M20x1.5-5.8 screw plug with a
DIN 7603-A20x24-Al washer.
The pump elements must be ordered accord-
ing to the required delivery rate.
4.3.2 KFGC (CAN bus) pump elements
3/2 directional solenoid valves can be em-
ployed so that lubricant connections can also
return the lubricant into the reservoir from
lubricant outlets which are not required at the
