Liquid System; Pump; Valves And Symbols - Hardi COMMANDER DELTA FORCE Instruction Book

Liquid System

Pump

Diaphragm pump with 6 diaphragms, model 464.
Standard speed = 540 rpm (6-spline shaft).
Optional speed = 1000 rpm (21-spline shaft).
The design of the diaphragm pump is simple, with easily accessible
diaphragms and valves, which ensures that liquid does not contact the
vital parts of the pump.
Pump model 464 is shown on the picture.
FlexCapacity pump
Some sprayers include a dual pump setup with an extra hydraulically
driven pump of the same type as the main pump. It is placed on the
sprayer's 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.
μ
ATTENTION! Only the functions used should be open - always close remaining valves.
μ
ATTENTION! If a valve is too tight to operate, or to loose (= liquid leakage, the valve needs to be serviced. Please see
"Adjustment of 3-Way Valve" on page 157 for further information.
Pressure Valve (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 desired symbol is just below the indicator mark. If the handle is turned to a position without a
label with a symbol (unused function), the valve is closed.
