Abstract
The invention relates to a fluid pump that has an electric motor with a shaft and an impeller with an outer diameter, that is connected to the shaft for conjoint rotation. A maximum volumetric flow and a maximum pressure difference (dp) can be generated in the fluid pump by the rotating impeller. A characteristic index number (K) for the fluid pump is greater than 350 kW/m. The index number (K) corresponds to the product of the maximum volumetric flow and the maximum pressure difference in the fluid pump divided by the square of the outer diameter of the impeller.
