Function
During sowing a centrifugal pump draws the
liquid fertiliser through a filter out of the hopper.
It runs through a control valve, the shut-off valve
and the flow meter.
Through the hose system it reaches the fertiliser
coulters and finally flows into the seed bed.
The 3-way valve in the line system allows switch-
ing between filling with pump, external filling and
empty hopper/place.
Liquid fertiliser pump
The pump is maintenance-free. It is hydraulically
driven and integrated in the fan drive. It can be
separately switched off.
