Abstract
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.
