Abstract
In an aspect, there is provided a pump impeller assembly that includes a first impeller portion arranged to drive a fluid through a fluid conduit, a second impeller portion movable between a more-rotationally engaged position in which the second impeller portion has a first amount of rotational engagement with the first impeller portion, and a less-rotationally engaged position in which the second impeller portion has a second amount of rotational engagement with the first impeller portion that is less than the first amount of rotational engagement, and an actuator operatively connected to the second impeller portion and configured to drive movement of the second impeller portion between the more-rotationally engaged position and the less-rotationally engaged position based on a fluid property.
