The vacuum system creates an atmospheric pressure difference in order to fill or empty the tanker. By creating a vacuum (depression) in the tank, slurry can be sucked. When spreading, the principle is reverse: the tank is pressurized by the pump, which allows to expel the slurry.
Advantages
Price/efficiency ratio
Limited wear (no slurry in the pump)
Low maintenance costs
user-friendly system

Vane
Rotary pump with eccentric rotor and forced lubrication system
The blades slide into the seatings of the moving rotor and are kept in contact with the pump housing under the action of the centrifugal power.
The moving blades ensure an air displacement creating a depression at the pump inlet and an overpressure at the outlet. The pump change-over allows to direct these flows, suck or spread.
Lobe rotors
Lobe pump with higher spreading capacity
Since there is no friction between the lobes, overheating and wear of the components are limited
It is an eco-friendly system since there is no lubrication system
The moving lobes ensure an air displacement creating a depression at the pump inlet and an overpressure at the outlet. The pump change-over allows to direct these flows, suck or spread.
Garda
GARDA system
The GARDA/JULIA system with 100% mechanical drive combines a Garda or Julia centrifugal pump with a vacuum pump (respectively Battioni & Pagani or Jurop). A pump change-over allows to choose the desired pump type. Standard delivered with a high-flow spreading gun, it is however still possible to feed a rear spreading implement or an umbilical system.
Advantages
Emptying through spreading gun to spread on very uneven grounds while the tanker remains on a flat area.
Irrigation works possible

Lobe pumps
Pumping system with lobe pump
Lobe pumps are volumetric pumps. This system uses the mechanical action of two lobe rotors. As they turn, they create a vacuum on the suction side, which is determined by the rotation direction, which allows to attract the slurry into the pump housing. Then, slurry is driven by the lobes, goes along the rotor wall and is spread.
These pumps do not take much place although they have a relatively high capacity. Their sucking principle ensures them a maximum stability and eliminates almost all vibrations. Furthermore, they are all standard fitted with an automatic stop system and wear rings. We propose pumps of the Vogelsangbrand.
Advantages
Higher speed when filling/emptying (depending on the pump flow)
Better filling level, especially with thick slurry and/or very deep pits
Possibility to pump up to 3.5 m deep
Standard equipment for mixing and transfer from pit to pit
Perfectly linear flow
High outlet pressure, for a good distribution even with large working widths

Storm
STORM Centrifugal Pumping System
The STORM system sends the slurry out of the pump thanks to the centrifugal power created by the rotation of a screw around an eccentric pump housing. The centrifugal pumping system certainly reaches the highest flows (up to 10,000 l/min).
Storm pumps only work when emptying. The tank is therefore filled by the gravitational force through an upper hydraulic access.
Advantages
Very high and linear slurry flow
Limited wear and low maintenance costs
Possibility to pump thick slurries
Low risk of cavitation
Pressure at the exit above 1 bar for a good distribution on high working width

Spiral
Pumping System with Spiral Pump
The spiral pump system makes use of a rotor with screw to suck and spread slurry. The rotation of the screw inside the stator then creates a series of hermetic chambers that move along the suction/discharge axis, resulting into suction and discharge.
Advantages
Higher speed when filling/emptying (according to pump flow)
Possibility to pump thick slurries
Compatible with very long pipes (pumping or spreading tool)
Possibility to pump up to 3.5 m deep
standard equipment for mixing and transfer from pit to pit
Pressure at the exit above 1 bar for a good distribution on high working width
