Abstract
A pump rotor includes a hub, a back plate and a plurality of blades extending from the hub and disposed on the back plate. Each of the plurality of blades has an outer surface essentially parallel to a rotational axis of the hub, and a first end adjacent the hub and a second end distal from the hub, the first end having a height from the planar surface that is less than a height from the planar surface of the second end. The plurality of blades is configured to cause a synchronized central column of flow.
Claims21
A pump rotor comprising:
- a hub having a rotational axis;
- a back plate having a planar surface;
- and
- a plurality of blades extending from the hub and disposed on the back plate,
- each of the plurality of blades having an outer surface essentially parallel to the rotational axis of the hub and a bottom surface opposite the back plate, and a first end adjacent the hub and a second end distal from the hub, the first end having a height from the planar surface that is less than a height from the planar surface of the second end, the bottom surface extending between the first end adjacent the hub and the second end distal from the hub and being planar,
