Pressure regulators with a volumetric valve (RPN-DPR-ERGO-REMO)

Adjusting the maximum pressure valve

=put main control A in the drain position (“OFF”).

=loosen the hand wheel of maximum pressure valve B completely (anticlockwise).

=open volumetric valve E completely.

=start the pump by activating the power-takeoff of the tractor at 540rpm

=open main control A (position “ON”), the manometer will be activated

=open the drain tap on filter F slightly (only ERGO and REMO)..

=close volumetric valve E completely. If the pressure rises over the maximum limit of the system, make sure maximum pressure valve B is open (see previous indications)

=open all of the section valves C (position “ON”)

=adjust maximum pressure valve B to a value over that of the working pressure (generally 10-14 bar) and in any case lower than the safe maximum pressure that the system can reach.

Adjusting the volumetric pressure.

=with the volumetric pressure valve E adjust the pressure to the value the treatment will be done at (the pressure is indicated on the nozzles tables on the basis of the tractor speed and litres/hectare to spray)

Warning! The working pressure must be adjusted with the volumetric valve and not with the maximum pressure valve. In the case the working pressure is too near to the calibrated pressure of the maximum pressure valve, the proportional valve may not be able to compensate the speed variations correctly.

Adjusting the compensated returns

=close only one tap of section C (position “OFF”).

=adjust the corresponding compensator G until you return to the pressure set previously (displayed on the manometer).

=open and close the tap of section C and check that the pressure remains constant.

=repeat the above operations for all the section taps.

If the types of nozzles aren’t changed the regulations carried out will guarantee a constant spraying of the liquid also per treatments that are done at different working pressures.

NB: if the type of nozzle is changed then the calibrating will have to be done again.

4.9DELIVERY FILTERS (ONLY EQUIPPED MODELS) Particularly useful when using small (low volume) nozzles.

In a central position with a manometer after the filter that shows any blockages in the cartridge. On the RVA version there is also a manometer before the car- tridge to make it easier to find the problem.

The cleaning of the cartridge in the RPV-DPR-ERGO-REMO series is fully au- tomatic (for ERGO and REMO see the previous paragraph), for the model RVA you should open the drain with the relevant lever (Fig. N° 4) for 2-3 minutes during the washing operations, as in the enclosed instructions.

You should clean the cartridge by hand periodically, on the basis of the product used. To clean, stop the pump. Wear rubber gloves and the other personal pro-

tective equipment when cleaning. Follow the instructions in the enclosed

FIG. 4

manual.

4.10 SPRAYING COMPUTER (OPTIONAL)

Scrupulously follow the instructions in the relevant manual when using.

We don’t recommend using the sprayer with the computer until you have had at least one lesson from the UNIGREEN technicians.

CAMPO 11 - 16 - 22 - 32, DSP 11 - 16 - 22 - 32 specifications

Unigreen DSP Series and CAMPO Series are advanced agricultural sprayers designed to meet the evolving needs of modern farming. The Unigreen DSP (Dynamic Spraying Product) models 11, 16, 22, and 32, along with the CAMPO models of the same specifications, are engineered for efficiency, precision, and reliability in crop protection.

One of the key features of the Unigreen DSP models is their innovative spraying technology. Each model is equipped with a high-capacity tank that allows for extended operation without the need for frequent refills. The DSP series incorporates adjustable booms that provide precise application across various crop types. This ensures uniform coverage and minimizes waste, making it an environmentally friendly option for farmers.

The CAMPO series also boasts similar tank capacities and boom adjustments, making them suitable for diverse agricultural applications. Both series offer customizable options, allowing farmers to choose the configuration that best fits their land and crop requirements.

Another standout characteristic of both Unigreen and CAMPO sprayers is their user-friendly interface. Equipped with advanced electronic controls, farmers can easily monitor and adjust spray rates, pressure, and other critical parameters in real time. This technology not only enhances the sprayers' operational efficiency but also aids in achieving the optimum application rates for different pesticides and fertilizers.

Furthermore, both series integrate cutting-edge GPS technology, enabling precision agriculture practices. This feature allows operators to map their fields, ensuring that every inch is accurately treated, while also reducing the possibility of overlap or missed areas. This precision application reduces chemical usage and ultimately leads to cost savings.

Durability is another primary focus in the design of the Unigreen DSP and CAMPO sprayers. Built with high-quality materials that can withstand harsh environmental conditions, these sprayers promise longevity and consistent performance over time.

In summary, Unigreen DSP and CAMPO models 11, 16, 22, and 32 are technologically advanced agricultural sprayers that combine efficiency, precision, and durability. With features such as adjustable booms, advanced electronic controls, and GPS technology, they cater to the diverse needs of today’s farmers, helping to enhance productivity while minimizing environmental impact. These sprayers are positioned to play a pivotal role in the future of sustainable agriculture.
