Fluid pump

The invention relates to a fluid pump (1) having an electric motor (6) with a shaft (7) and having an impeller (4) which is connected to the shaft (7) in a rotationally fixed manner and has an outer diameter (d). A maximum volume flow # imgabs0 # of the fluid pump (1) and a maximum pressure difference (dp) of the fluid pump (1) can be generated by means of the rotating impeller (4). A characteristic parameter (K) of the fluid pump (1) is greater than 350 kW/m2. In this case, the characteristic parameter (K) corresponds to the product of the maximum volume flow # imgabs1 # of the fluid pump (1) and the maximum pressure difference (dp) of the fluid pump (1) divided by the square of the outer diameter (d) of the impeller (4). 本发明涉及流体泵(1)，该流体泵具备带有轴(7)的电马达(6)且具备抗相对转动地与轴(7)连接的带有外径(d)的叶轮(4)。借助旋转的叶轮(4)能产生流体泵(1)的最大体积流量#imgabs0#和流体泵(1)的最大压差(dp)。流体泵(1)的具有表征性的特征参数(K)在此大于350kW/m2。特征参数(K)在此相当于流体泵(1)的最大体积流量#imgabs1#和流体泵(1)的最大压差(dp)的乘积除以叶轮(4)的外径(d)平方。
