PUMPING DEVICE

摘要

The invention relates to a pumping device for introduction of a fluid into a base layer, in particular into a base layer containing gas, for the production of gas-permeable structures in the base layer. The pumping device is arranged on a transportation vehicle having a separate drive unit, including a pump motor and a pump, whereby a speed/torque converter is arranged between pump and pump motor. A hydrodynamic device, in particular a hydrodynamic converter, is used in place of a transmission for speed/torque conversion.
