jbs vario E

applicator for liquid silage additives, applies 4 - 17 l/h

At a glance

  • easy to handle
  • may be used with all liquid biological silage additives
  • very exact application
  • variable control of flow rate
  • excellent spray pattern (may be adjusted by changing the nozzles)
  • apply additives up to ten hours using just 40 litre of liquid
  • attractive price

jbs vario E is an inexpensive, yet exact and uncomplicated solution to apply biological silage additives without being limited to using a certain product only. It enables you to chose flow rates between 4 and 17 l/h - depending on the nozzle you select.

Due to its reasonable price and easy handling, larger motor pools may be equipped or several choppers may be set up with tanks in advance, thus enabling you to install jbs vario E to one of the vehicles according to need within a short period of time.

Usage instructions

The bayonet nut on the nozzle carrier allows rapid changing from the first (4 - 8 l/h) to the second enclosed nozzle (8 - 17 l/h) in order to ensure an optimal spray pattern at all times. An integrated non-return valve keeps the applicator from dripping. When operating the pump for the first time, open the non-return valve for airing until liquid drips out of the valve and no more bubbles remain in the hose. In order to avoid conglutination of the parts from silage additive residues or in order to dissolve possible block-ages after a longer period of non-use, we recommend running the applicator with clean water.

The flow meter comes with a display range of 2.5 - 25 l/h. If possible, use hose clips to fix flow meter in uninterrupted sight of driver. In any case, the flow meter needs to be installed vertically (upright).

Combined with the electronic control unit, it guarantees an exact applicability at all times. As the flow meter is calibrated with water we recommend calibrating the applicator once more after the installation in order to be able to adjust the application if necessary.

All parts have to be thoroughly cleaned on a regular basis.

The electronic control unit is installed in the chopper’s cabin, thus enabling the driver to control pump performance variably by using the control dial. Connect the unit to the chopper’s 12-V on-board electronic system (see sketch below).

Voltages above 12 V may damage the unit!

The unit is protected by a fuse. Do mind the correct polarity when connecting the unit - otherwise, the unit will be damaged.

The pipe filter ensures blockage-free operation of flow meter and nozzles. It should regularly be opened for cleaning (rinse with cold water).

The 12-Volt immersion pump is to be connected to the electronic control unit. The pump has a forced ventilation and cannot run dry - however, it should not run without liquid for longer than 10 - 15 minutes. The jet of water dripping out next to the hose connection on top of the pump removes air from the pump. As mechanical force may break the hose-vent connection, it should be handled with care.

When using a large tank, make sure that the pump reaches the bottom of the tank. Do not apply tensile strain to the power cable connected to the pump as otherwise, the sealing gasket between pump and motor may be pulled out thus enabling water to penetrate the motor.

On installation, mind the correct polarity of the cables, as otherwise, the pump will not draw in the silage additive.

Any clean container may be used as a tank. We recommend using jerrycans (approx. 25 litre).

Only remove cable loop if you want to connect the applicator to a pick-up switch!
