Liquid system

Pump

Diaphragm pump with 6 diaphragms, model 463. Standard = 540 r.p.m. (6 splines shaft). Optional = 1000 r.p.m. (21 splines
shaft). The design of the diaphragm pump is simple, with easily accessible diaphragms and valves which ensures liquid does
not contact the vital parts of the pump.
FlexCapacity pump
Some sprayers facilitates a dual pump setup with an extra hydraulically driven pump of same type as the main pump, placed
on sprayers right side.
The FlexCapacity pump is turned ON/OFF with a separate hydraulic lever in the tractor cabin.

Valves and symbols

The possible functions of valves are distinguished by coloured identification on the function labels. The modular valve
system facilitates the addition of optional extras on both pressure side and suction side. A function is activated by turning
the handle towards the desired function.
ATTENTION! Only the functions used should be open - always close remaining valves.
ATTENTION! If a valve is too tight to operate - or to loose (= liquid leakage) - the valve needs to be serviced. Please see
"Pump valves and diaphragms renewal" on page 93 for further information.
Pressure SmartValve (Green symbols)
This valve is to select which function the pressurized liquid from the
pump will be routed to.
The active function is indicated by the indicator. The handle is turned so
the indicator points to the label for required function. If handle is turned
to a position without label (unused function) then the valve is closed.

Internal tank cleaning
(Rinsing nozzles)
Suction SmartValve (Blue symbols)
This valve is to select suction from main tank or from the rinsing tank.
The handle is turned so the label for required function is directed to the
indicator. If handle is turned to vertical position (indicator not pointing
at a label) then the valve is closed.
