Abstract
Technologies are generally described for holding an impeller of a pump assembly in place axially with an impeller locking collar by loading the collar against a ring element. In a centrifugal pump assembly, one side of the shaft has a larger diameter for the impeller to abut against. The other side of the shaft may be fitted with an impeller locking collar comprising two portions that can be threaded together and hold the impeller in place by tightening against a ring element such as a split ring or spiral lock. Anti-rotation to avoid loosening of the impeller locking collar may be achieved by providing counter threads against a shaft rotation. Secondary anti-rotation may be provided by one or more set screws in the impeller locking collar.
