4.3 Pump elements
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 accor-
ding to the required delivery rate.
4.3.2 KFGC (CAN bus) pump elements
3/2 directional control valves can be employed
so that lubricant connections can also return
the lubricant into the reservoir from lubricant
outlets which are not required at the moment.
Close any outlets which are not required using
a DIN 910-M20x1.5-5.8 screw plug with a
DIN 7603-A20x24-Al washer.
