Winter services

These gear pumps have been developed specifically for targeted de-icing of roads and airports. Exact dosing of the liquid de-icing agent is possible, since the drive can be controlled precisely through use of the gear-pump principle in combination with high-resolution speed sensors. The gear pumps are resistant to corrosion.
