A device (10) for carbonating drinking water with carbon dioxide (CO2) is described, comprising a main body (12) configured to house a first positive displacement pump (14) and a second positive displacement pump (16) connected in series. The main body (12) also comprises at least one inlet duct (18) for the water to be carbonated, a first inlet duct (22) for the carbon dioxide (CO2), positioned upstream of the first positive displacement pump (14), a second inlet duct (28) for the carbon dioxide (CO2), positioned downstream of the first positive displacement pump (14) and upstream of the second positive displacement pump (16), and at least one outlet duct (42) for the carbonated water. A first step of carbonating the water with carbon dioxide (CO 2 ) takes place in the thrusting step inside the chamber of the first positive displacement pump (14) and a second step of carbonating the water with carbon dioxide (CO 2 ) takes place in the thrusting step inside the chamber of the second positive displacement pump (16). |
