4.6 Progressive distributors (option)
Progressive distributors VPB can be directly
flange-mounted on the pump elements, but
limited to 2 units with up to 20 outlets each and
various feeding volumes.
The following progressive distributors can be
flanged directly:
VPB-B Data sheet P0378
VPB-G Data sheet P0177
In case of attached progressive distributors,
the 0,16 cm³ delivery volume pump element
is marked with a grey plastic nap
N
.
Functioning:
In the distributor, the lubricant supplied by the pump element is delivered to the outlets
progressively.
For more information about the functioning of the distributors see data sheets P0378 and
P0177, respectively.
Functional control:
In conjunction with the monitoring of the movement of a distributor piston, the lubricant
supply to all outlets is monitored. When evaluation is to be made via pump control, pro-
gressive distributors with electric functional control need to be selected.
When, however, using the pump controller, one distributor each can be
monitored only.
