L22. Tank Bypass Return Shut-Off Valve
(variable rate ground drive implements only)
This Nutri-Pro
®
manual mentions only a single
shutoff valve for the tank bypass return hose. Your
tank may have additional shutoff and/or flow
management valves. Consult your tank manual.
L23. Tank Bypass Return Inlet
(variable rate ground drive implements only)
The return outlet of the NP30L or NP40L applicator
is a
3
/
4
inch cam-lock quick coupler plug (male,
MCL). The tank bypass return hose fitting must be,
or be adapted to
3
/
4
inch FCL.
Implement System Components (Option)
This list presumes that the implement has system
components factory-installed by Great Plains. The list
includes all components for both pumping systems
(preset and variable rate). If the implement has
aftermarket components, part or all of this information
may not apply to your operations.
L24. Supply Inlet
The supply inlet of ground drive NP30L or NP40L
applicator is a 2 inch cam-lock quick coupler
receptacle (female, FCL). The tank supply hose
fitting must be, or be adapted to 2 inch MCL.
The supply inlet for hydraulic drive is a 1
1
/
2
inch
unterminated hose. This requires an inlet coupling
compatible with the nurse tank to be used. An
applicator-side shut-off valve is recommended.
L25. Inlet Shut-off Valve
Where present, this valve is open for application
and clean-out, and closed at all other times.
L26. Return Outlet
(variable rate ground drive implements only)
With the variable rate feature, the pump dial
is
typically set to maximum rate. Flow control
valve
diverts excess fertilizer back to the tank.
The return outlet of the NP30L or NP40L applicator
is a 2 inch male cam-lock quick coupler (MCL). The
tank return hose fitting must be, or be adapted to
2 inch FCL.
L27. Return Outlet Shut-Off Valve
(variable rate ground drive implements only)
This valve is open for application and clean-out, and
closed at all other times.
L28. Bypass Return Outlet
(variable rate ground drive implements only)
The return outlet of the NP30L or NP40L applicator
is a
3
/
4
inch cam-lock quick coupler plug (male,
MCL). The tank bypass return hose fitting must be,
or be adapted to
3
/
4
inch FCL.
L29. Bypass Return Shut-Off Valve
(variable rate ground drive implements only)
This valve is open for application and clean-out, and
closed at all other times.
L30. Strainer
This fitting contains an 80 mesh screen for filtering
large particles and coagulates in the fertilizer,
preventing blockage at the orifice plates
. See
page 90 for alternative screen sizes and page 104
for maintenance.
L31. Ground Drive Pump
The CDS-John Blue NGP-7055-K has a capacity of
34 gallons/minute (129 liters/minute). See the
CDS-John Blue NGP Pump Parts and Instructional
manual (12-M-43) for maintenance.
L32. Pump Adjustment Dial
(ground drive implements only)
This 0-to-10 adjustment sets the percentage of
rated gpm/lpm to use. Settings below 2 are not
recommended.
Preset Rate:
Pump and application rate are set by a combination
of ground drive sprockets (not shown) and dial
setting. See page 92 for preset rate setting.
Variable Rate:
The pump is typically operated at dial setting 10,
using whichever ground drive sprocket provides
higher-than-needed gpm/lpm. Application rate is
controlled by valve
, which diverts excess flow
back to the nurse tank.
L33. Pump Adjustment Tool
(ground drive implements only)
Adjusting the setting dial may require some
mechanical assistance. A slot is provided to store
the tool at the pump when not being used for
adjustments.
L34. Gauge Protector
(ground drive implements only)
This fitting transmits manifold pressure to the
pressure gauge
, and protects the gauge from
direct contact with corrosive fertilizer.
