Description
The Hardi NL models consist of a pump, frame with tank of 300, 400,
600 or 800 litre capacity, M-70 operating unit, SB booms (if fitted) of 6,
8, 10, or 12 metre and transmission shaft.
The design of the diaphragm pump is simple, with easily accessible
diaphragms and valves that ensures liquid does not come in contact
with the vital parts of the pump.
The tank, made of impact-proof and chemical resistant polyethylene,
has a purposeful design with no sharp edges for easy cleaning and
efficient agitation. A suction filter is located at the top of the tank. This
facilitates filter inspection even if the tank is filled with spray liquid.
The M-70 operating unit consists of; on/off function, pressure regula-
tion valve with pressure gauge and distribution valves for closing of
spray boom sections.
The SB boom is bolted to the tank frame and is fitted with spring
loaded breakaways at the pivots.
An identification plate fitted on the frame indicates model, year of
production and serial number, and country of origin.
