(54) Title: ANTI-SPIN PUMP DEFFUSER (57) Abstract: An electric pump may include a stack of diffusers including a first diffuser and a second diffuser. The first diffuser includes a recess therein defining an inner recess surface sub-90        stantially circumscribing a primary diffuser axis. The second dif-r, s-Al 82 fuser includes a lip projecting into the recess of the first diffuser. In response to a differential torque applied to the first and second 78b diffusers about the primary diffuser axis, the lip of the second diffuser may engage the inner recess surface of the first diffuser, and thereby prevent relative rotation of the diffusers with respect 90a                           "owl) a to one another. An outer perimeter surface of the lip and the inner _Iy-H recess surface may define polygonal shapes or other non-circular 92                                _4::=_ profiles.
