The HARDI Navigator 550M, 800M and 1000M diaphragm models consist of
*
a pump, frame with tank, EC or EVC controls (Electric Controls) and Manifold
System. The Navigator 550M model is available with either the hydraulic folding
Eagle™ SPB series spray boom available in 45', 50', 60' or 66' widths or a manual
fold boom (MB) available in 42', 45' or 50' widths. The Navigator 800M*/1000M
model is available with the hydraulic folding Eagle™ SPC series spray boom
available in 80' 88' or 90' widths.
The heart of your sprayer is the diaphragm pump. Because the design is simple,
low maintenance requirements and pump life is guaranteed. The bearings and
crankshaft are grease lubricated and are therefore protected from spray solution
if any diaphragm fails in service. A drain hole is in the base of the crank case to
facilitate draining of any foreign matter. The pump is self priming and can be run
dry without damage.
The tanks, made of impact proof and chemical resistant poly eth yl ene, have a
purposeful design with rounded contours which allows for ef fi cient cleaning and
draining. The tanks are designed with a large deep sump, so that they can be
completely emptied even when the sprayer is used on slopes up to 15% inclination.
A remote operated valve drain is fi tted for effi cient draining.
The EC (electric control) unit, used on 60' - 90' booms, consists of: ON/OFF control
valve, self-cleaning fi lter, pressure regulating valve with built-in HARDIMATIC,
2-1/2" pressure gauge and distribution valves with pressure equalization.
The EVC (electric control) unit, used on 42' - 50' booms, consists of: pressure
fi lter, pressure regulating valve with with built-in HARDIMATIC, 2-1/2" pressure
gauge and distribution valves with pressure equalization. ON/OFF control of the
spray boom is done only by the individual boom section valves.
HARDIMATIC is a mechanical rate controller that ensures a constant volume
of spray solution per acre even at varying speeds in the same gear. Maximum
performance of the HARDIMATIC is obtained with a P.T.O. shaft speed between
300-600 r.p.m. (540 r.p.m. pump) or 650-1100 (1000 r.p.m. pump).
The "Manifold System" features color coded three way valves on suction and
pressure sides of the liquid control system. It allows for safe and simple use of
the sprayer and accessories from one centralized location.
The self-cleaning fi lter screens out impurities from the spray solution which are
recirculated back to the main tank while clean solution is constantly being supplied
to the boom.
The Eagle™ coil spring suspended hydraulic series boom is available with either
3 (HY model) or 5 (HZ model) hydraulic cylinders. The base version being the HY
model, includes boom height adjustment and fold/unfold features all controlled from
the tractor. The HZ model has all the same features as the HY model but also includes
individual wing tilt and fold with a 'joystick' control handle. An optional electrical
'DH' control for closed center hydraulics is available. Both versions require single
and double acting hy drau lic outlets on the tractor as well as a 12V connection for
the HZ model. The MB (manual fold boom) offers hydraulic height adjustment as
standard equipment and hydraulic wing tilt as an option.
The Navigator 800M is no longer available
