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.

A centrifugal pump to improve the efficiency of fluid flow, and minimize long term wear on the pump by progressively increasing fluid pressure as fluid moves from an eye of an impeller towards diffuser blades, into the volute and out through an outlet. The fluid pressure is increased by progressively increasing the volume through which the fluid travels. A tear-drop shaped volute casing surrounding the diffuser and impeller creates a pocket of maximum pressure just below the outlet. A dampener can be provided to dampen the vibration of the motor. A cylindrical basket strainer can be provided with a flat face abutting against the volute casing to distribute pressure evenly. A clamp ring can be provided to easily seal and access the basket strainer using a plain rod.

A variable mechanical automotive coolant pump includes a rotatable rotor shaft, an impeller wheel which is co-rotatably connected with the rotor shaft, a static guiding cylinder, a control sleeve, and at least one guiding device. The impeller wheel has a discharging radial outside. The control sleeve has a hollow-cylindrical control sleeve body having a radial outside. The control sleeve does not rotate and is guided axially slidable within the static guiding cylinder so as to regulate a flow rate of the variable mechanical automotive coolant pump by closing or opening the discharging radial outside of the impeller wheel. The at least one guiding device guides the radial outside of the control sleeve within the static guiding cylinder.
