Fan impeller for e.g. non-positive displacement pump
The impeller has a width ratio, b2/D of between (0.2,0.6) and a predominant radial throughflow. The radial extent, (D-d1) /D of the radial impeller blade grid (1) reduces from a region of the support wheel (2) to the cover wheel (3). The exit edges (4) of the blades rise outwardly, whereby the grid...

| description | The impeller has a width ratio, b2/D of between (0.2,0.6) and a predominant radial throughflow. The radial extent, (D-d1) /D of the radial impeller blade grid (1) reduces from a region of the support wheel (2) to the cover wheel (3). The exit edges (4) of the blades rise outwardly, whereby the grid outlet diameter D increases. The support wheel is inclined against the direction of flow and towards the rotational axis of the impeller. The radial blade lattice begins at the support wheel when the radial ratio, d1/D is greater than or equal to (0.5), and stops when it is greater than or equal to 75. |
