The invention relates to a dosing device comprising a housing comprising at least one inlet, at least one outlet, and a liquid flow path extending from the inlet to the outlet. The dosing device is adapted for dispensing in a metered manner a viscous concentrate from a holder. The concentrate in diluted condition forms a beverage suitable for consumption. The dosing device is adapted to be connected, in use, to a storage space of the holder. According to the invention, the dosing device comprises a gear pump to be included in the liquid flow path, which gear pump can be driven in particular by a rotor located upstream of the gear pump, by means of changing magnetic fields.
