Adaptive Volute Geometries for Centrifugal Pumps

Centrifugal pump systems and related methods are disclosed herein that can shift a best efficiency point of a pump based on one or more operating conditions to operate more efficiently across and/or adjust to a broader range of conditions. Pumps provided for herein can include an adaptive volute in which a geometry of the volute can be adjusted to shift an operating efficiency of the pump. In some embodiments, a height or radial dimension of the adaptive volute can be adjusted based on one or more operating condition. A geometry of the adaptive volute can be adjusted during operation of the pump and/or while an impeller is disposed within the volute. In some embodiments, a first and second collar can be disposed within the adaptive volute. Rotation of the first component can move the second component axially, which can expand or contract an axial dimension of the adaptive volute.
