Downhole centrifugal pumps and related components and methods may include stationary diffusers housing impellers where the stationary diffusers have radial sidewalls defining a radially outer portion of each of the stationary diffusers. Coupling pins may extend between and engage with the radial sidewalls of the stationary diffusers to at least partially transfer a rotational force applied to one or more of the stationary diffusers to one or more of the remaining stationary diffusers.

Downhole centrifugal pumps including locking features and related components and methods

Downhole centrifugal pumps and related components and methods may include diffusers housing impellers and a rotational shaft passing through the impellers to impart rotation to the impellers. Bearings are positioned within at least some of the diffusers to support the rotational shaft during the rotation of the impellers. Coupling pins may be positioned between and engage with the bearings and the at least some of the diffusers to at least partially secure each of the bearings to one of the at least some of the diffusers.
