Abstract
A vortex pump impeller utilizes primary blades in combination with splitter blades. An increase in total head is observed through exemplary impellers in a vortex pump, compared to an impeller lacking the splitter blades. Single stage and dual stage pumps utilizing the exemplary impellers are also disclosed. Exemplary pumps may also contain a grinder assembly.
Claims15
An impeller, for use with a vortex pump, comprising:
- a circular base plate with a central axis of symmetry and a face surface defining a plate periphery;
- a plurality of primary blades, each primary blade extending axially from the face surface and extending in the radial direction beginning at a first point outwardly from the central axis and ending at the plate periphery;
- and
- a plurality of secondary blades, each secondary blade extending axially from the face surface and extending in the radial direction from a second point outwardly from the central axis to the plate periphery, with one secondary blade arranged between each adjacent pair of primary blades, the second point being further in the radial direction from the central axis than the first point.
1 more element
An impeller, for use with a vortex pump, comprising:
- a circular base plate with a central axis of symmetry, with a face surface defining a plate periphery;
- a plurality of flow channels formed symmetrically around the face surface, each flow channel extending from the plate periphery to a first point radially outward from the central axis, each flow channel bisected by a splitter member that extends from the plate periphery to a second point that is radially outward from the central axis, the second point being farther from the central axis than the first point.
