Spraying with FlexCapacity pump
On conventional P.T.O. systems, both the P.T.O. pump and the hydraulic FlexCapacity pump deliver constant flow when
engaged. Therefore the spray pressure is controlled by the regulation valve when:
•
Valves/sections are opened or closed.
•
Speed is increased or decreased, etc.
When specific driving conditions or large nozzles makes the regulation valve unable to adjust to correct pressure because
of too large or too low flow, i.e. regulation valve is completely open or closed, it requires the FlexCapacity pump to be turned
ON/OFF - in general:
•
Turn FlexCapacity pump ON when nozzle pressure gets too low. Controller prompts the warning “Increase pump flow”.
•
Turn FlexCapacity pump OFF when nozzle pressure gets too high. Controller prompts the warning “Reduce pump
flow”.
